Is Lead Poisoning Reversible? Recovery, Timelines and What Lasts

Lead poisoning is partly reversible. Once exposure stops, the amount of lead in the blood goes down, but lead stored in the bones can stay for decades, and the CDC says some effects of lead poisoning “can be permanent and disabling,” especially on a child’s developing brain.

In short: you can recover in the sense that blood lead levels fall once the source is found and removed. ATSDR, the CDC’s toxic-substances agency, estimates the half-life of lead in adult blood at 28 to 36 days, about a month, while lead in bone has an apparent half-time of one to two decades. Damage that has already happened, such as effects on learning and IQ, may not reverse, which is why the CDC focuses on stopping exposure early and on support services for children. There is no home treatment or detox. If you are worried, call your doctor, your local health department or Poison Control at 1-800-222-1222.

This page sums up what the CDC, ATSDR, NIEHS and the World Health Organization publish. It is not medical advice; only a provider who knows the person can say what to expect.

What “recovery” from lead poisoning means

Recovery means two things: will the lead leave the body, and will the effects go away? Official sources answer them separately.

For the lead itself, the answer is mostly yes, slowly. ATSDR’s course for doctors says repeat blood tests are used “to verify the decline in BLL after lead sources have been reduced or eliminated.” A falling blood lead level is the main sign of recovery. How fast it falls depends on how high the level was, how long the exposure lasted, the person’s age, and how much lead has built up in the bones.

For the harm, the answer is less certain. NIEHS states that “many effects are permanent,” and official sources do not promise that any specific effect will reverse. Our guide to the effects of lead poisoning lists what each agency describes, and our lead poisoning hub covers the basics.

How long does lead stay in your body?

ATSDR describes three places lead goes: blood, soft tissues, and bones and teeth. The bones and teeth of adults hold about 94% of the body’s lead; in children, the figure is about 73%. Lead leaves the blood much faster than it leaves the bone, and bone can feed lead back into the blood for years. ATSDR’s 2020 Toxicological Profile for Lead puts it plainly: lead “is retained in the body for decades.”

The published timeframes below are averages and ranges from studies, not a forecast for any one person.

Timeframe	What happens	Source
About a month (28 to 36 days)	Estimated half-life of lead in adult blood: roughly half of the lead in the blood is gone in that time, if no new lead comes in and bone does not add more.	ATSDR, Case Studies in Environmental Medicine: Lead Toxicity
1 week to 2 years	The apparent half-time of lead in blood “varies with age and exposure history.” Long or heavy exposure builds bone stores that slow the decline.	ATSDR Toxicological Profile for Lead (2020)
8 to 38 months	Apparent blood half-times estimated in one study of children exposed at ages 2 to 3. ATSDR notes these include lead moving from bone back into blood.	ATSDR Toxicological Profile for Lead (2020), citing Manton et al. 2000
2 weeks to 9 months between tests	The CDC’s follow-up blood test schedule for children, set by the confirmed level: higher levels are checked sooner.	CDC, Recommended Actions Based on Blood Lead Level
1 to 2 decades	Apparent half-time for elimination of lead from bone.	ATSDR Toxicological Profile for Lead (2020)
Several decades	One part of bone lead is “essentially inert,” with an elimination half-time of several decades; ATSDR’s course says it “stores lead for decades.”	ATSDR Toxicological Profile (2020); ATSDR Case Studies in Environmental Medicine
Years later	Stored bone lead can return to the blood during pregnancy, breastfeeding, menopause, broken bones, long bed rest, kidney disease and older age.	ATSDR Case Studies in Environmental Medicine; CDC, Risk Factors and Pregnancy
Possibly lifelong	Some effects, such as on a child’s brain development and IQ, can be permanent.	CDC; NIEHS; WHO

So how long does lead poisoning last? No official source gives a single answer. A level built up over years comes down more slowly than one from a short exposure, because bone keeps releasing lead. In one study of retired lead workers cited by ATSDR, about half of the blood lead decline had a half-time of 13 years.

Lead stored in bone can come back

Because so much lead is stored in bone, a person can have lead in their blood long after the original source is gone. ATSDR calls this inert pool “a potential endogenous source of lead that can maintain BLLs long after exposure has ended.” Release increases with pregnancy, breastfeeding, menopause, advanced age, broken bones, being bedridden, kidney disease and some other conditions, and ATSDR says calcium deficiency makes it worse.

Pregnancy matters most here. The CDC says “the lead stored in the bones of adults can be released into the blood during pregnancy,” and WHO says this lead “becomes a source of exposure to the developing fetus.” If you are pregnant or planning a pregnancy and think you were exposed in the past, tell your health care provider.

This is also why a child’s level can rise again. ATSDR lists four reasons for a rising level: a source no one has found yet, abatement work that was not done properly, a known hazard that was not controlled, or lead stored in the child’s body moving back into the blood.

Which effects may be permanent, and what can improve

Official sources are direct about the permanent side. The CDC says “the effects of lead poisoning can be permanent and disabling” and that there are no safe levels of lead in the blood. WHO says lead “can permanently affect children’s brain development, resulting in reduced intelligence quotient (IQ),” along with shorter attention span and lower educational attainment, and that children who survive severe poisoning “may be left with permanent intellectual disability and behavioural disorders.”

What improves is the level of lead in the body. Stopping exposure prevents more damage, and that is the part families and health departments can control. For children, the CDC also points to services that help a child learn and develop, covered below; they support the child rather than undo effects.

Why removing the source is the most important step

A blood lead level cannot fall for long while new lead keeps coming in. That is why “finding and removing lead from the child’s environment” comes first in the CDC’s list of follow-up services, and why ATSDR tells doctors to start a prompt investigation for the source. Above the CDC reference value of 3.5 µg/dL, providers report the result to the health department, which may arrange a home investigation; the rules vary by state or city.

Common sources include deteriorating paint and the dust it makes in homes built before 1978, water from lead pipes, bare soil, lead brought home on work clothes, and some imported spices, remedies, cosmetics and pottery. See lead poisoning causes and prevention, or try our free home lead risk checker. Do not sand or scrape old paint yourself; that makes more lead dust.

Follow-up blood tests: how recovery is tracked

The only way to see recovery is repeat blood tests. For children, the CDC sets the timing by the confirmed (venous) level: early follow-up in 3 months for 3.5 to 9 µg/dL, 1 to 3 months for 10 to 19, 2 weeks to 1 month for 20 to 44, and as soon as possible for 45 or higher. Once levels are falling, the gaps get longer, up to 6 to 9 months. The full table is on our blood lead levels page.

Support for children: early intervention and school services

Because some effects can last, the CDC’s follow-up for children goes beyond the blood test. The CDC tells parents that a doctor “may also recommend connecting the child to early educational services.” Its guidance for providers says to check that the child is meeting developmental milestones and to refer families to supportive services as needed, such as developmental specialists and the Early Intervention Program.

A 2015 CDC expert panel report, Educational Interventions for Children Affected by Lead, notes there are no studies specifically on early educational interventions for lead-exposed children, but that children with or at high risk of developmental delays benefit most from interventions that start early. It calls for streamlined access to developmental assessment, intervention and special education services, and for consistent use of the Individuals with Disabilities Education Act (IDEA). Ask your child’s doctor about a developmental evaluation, and tell the school about the exposure. Our guide to lead and children has more on prevention and screening.

Nutrition: what the CDC says

The CDC’s wording on food is short. For children above the reference value, its follow-up services include “feeding the child a diet high in iron and calcium.” Its prevention advice for families says “a balanced diet with foods that provide calcium, iron, and vitamin C may help keep lead out of the body,” and notes that many of these foods can be bought through food assistance programs such as WIC.

A good diet supports the body; it does not remove stored lead and is not a treatment. Do not give supplements for lead unless your own or your child’s doctor tells you to.

Medical treatment at high levels

At very high blood lead levels, doctors may use chelation therapy, which the CDC describes as “a medical treatment used to remove lead from the body.” The CDC’s provider guidance places it at 45 µg/dL and above, decided with a medical toxicologist or a pediatrician experienced in lead poisoning, and ATSDR says chelation is not risk free. It lowers the lead load; it is not described by official sources as reversing damage already done. Our lead poisoning treatment guide explains the CDC’s actions at each level, and which doctor treats lead poisoning explains who to see.

Products sold online as lead “detox” or home chelation are not the same thing, and no official source we use recommends them.

Adults

Most adults with high blood lead were exposed at work, according to NIEHS, in jobs such as construction, mining, welding and battery manufacturing. Blood lead falls after exposure ends, more slowly after years of exposure. If you work with lead, tell your doctor.

Who to call

911 for severe symptoms such as a seizure, collapse or trouble breathing.
Poison Control, 1-800-222-1222, free and around the clock, if you think someone swallowed lead or you have urgent questions.
Your doctor or your child’s pediatrician for blood lead tests, follow-up and referrals.
Your local health department for case management and home investigations.

Frequently asked questions

Is lead poisoning reversible?

Partly. Blood lead levels come down once exposure stops, but lead stored in bone can stay for decades, and the CDC says some effects can be permanent. Stopping exposure early limits the harm.

Can you recover from lead poisoning?

Blood lead levels fall after the source is removed, tracked with repeat tests. Whether effects on learning or health improve varies; official sources describe some as permanent.

How long does lead poisoning last?

There is no single timeline. ATSDR estimates the half-life of lead in adult blood at about a month, but levels built up over years fall more slowly because bone keeps releasing lead. The CDC schedules children’s follow-up tests 2 weeks to 9 months apart depending on the level.

How long does lead stay in your body?

In the blood, weeks to months; in bone, years to decades. ATSDR gives an apparent half-time of one to two decades for lead in bone, and says part of it is stored for several decades.

Can lead come back years later?

Yes. ATSDR says bone lead can move back into the blood during pregnancy, breastfeeding, menopause, after a broken bone or with older age.

Can Lead Poisoning Kill You? Lead Poisoning Statistics and Deaths

Yes, lead poisoning can kill, but in the United States today it almost never does so quickly. The World Health Organization says lead exposure was linked to more than 3.5 million deaths worldwide in 2023, mostly through its effects on the heart and blood vessels after years of exposure, while sudden deaths from very high levels, usually in young children who swallowed something made of lead, are rare in the US and are reported as individual cases.

In short: most lead-related deaths come from long-term, lower-level exposure that raises blood pressure and the risk of heart disease in adults. Fast, fatal poisoning is rare in the US but has happened, for example in a 4-year-old who swallowed a lead charm in 2006. Lead levels in US children have fallen by about 96% since the late 1970s, yet millions of homes still have lead paint hazards and about 4 million lead water pipes remain in the ground. No safe blood lead level is known, so prevention and testing still matter. For a possible poisoning, call Poison Control at 1-800-222-1222, or 911 in an emergency.

This page gathers public statistics from health and housing agencies and one peer-reviewed study. It is not medical advice. Talk to a doctor or your local health department about your own situation.

Can lead poisoning kill you?

It can, in two very different ways.

Slowly, through the heart and blood vessels. This is where most lead-related deaths come from. The WHO says lead contributes to high blood pressure, heart and blood vessel problems and kidney damage in adults. Over many years that raises the chance of dying from a heart attack or stroke.
Quickly, from a very high dose. A large amount of lead in a short time, for example from a swallowed lead object, can cause serious brain injury (lead encephalopathy) and death. In the US this is now rare.

So the honest answer to “can lead poisoning kill you” is yes, but the main danger for most people is quiet and long-term, not sudden. More in our guide to the effects of lead poisoning.

Lead poisoning deaths: what the numbers really say

The WHO figure: 3.5 million deaths worldwide

The WHO’s lead fact sheet, dated June 10, 2026, cites the Institute for Health Metrics and Evaluation (IHME): more than 3.5 million deaths globally in 2023 were attributed to lead exposure, “primarily due to cardiovascular effects.” It is a modeled estimate, not a tally of death certificates that say lead poisoning.

The US estimate: about 412,000 deaths a year

A 2018 study in The Lancet Public Health by Bruce Lanphear and colleagues followed 14,289 US adults whose blood lead was measured in a national survey from 1988 to 1994, and linked them to death records through 2011. The researchers estimated that 18% of all deaths, equivalent to about 412,000 a year, could be attributed to lead, including about 256,000 cardiovascular deaths and 185,000 deaths from ischemic heart disease.

This is a peer-reviewed research estimate, not an official CDC count. It is also based on blood lead levels from the late 1980s and early 1990s, when the average adult level in the study was 2.71 µg/dL; lead levels have fallen a great deal since, as the children’s data below show. It shows how large the long-term effect may be, not today’s yearly toll.

Is there an official US count?

We could not find a current CDC or NCHS page that publishes a national yearly count of deaths from lead poisoning, so we do not quote one. A heart attack in someone with years of exposure is not recorded as lead poisoning.

Fatal lead poisoning in children is rare, but it has happened

In a 2001 report the CDC called fatal lead poisoning in US children rare, crediting public health measures. Two cases published in its Morbidity and Mortality Weekly Report (MMWR):

New Hampshire, 2000. A 2-year-old girl who had arrived three weeks earlier with her refugee family died with a blood lead level of 391 µg/dL. The CDC called it the first reported death of a child from lead poisoning since 1990, and the investigation pointed to lead paint and dust in the home.
Minnesota, 2006. A 4-year-old boy died of lead encephalopathy after swallowing a heart-shaped charm that tested at 99.1% lead. It came on a bracelet given free with a pair of shoes; his blood lead level was 180 µg/dL. The bracelets were recalled.

For comparison, the CDC’s reference value for children is 3.5 µg/dL, so these children had levels more than 50 times higher. Keep small metal jewelry and charms away from young children; see lead and children. If a child may have swallowed a metal object, call Poison Control at 1-800-222-1222 right away, or 911 for severe symptoms such as a seizure.

How common is lead poisoning in the US?

It depends on what you count, because no level of lead is known to be safe.

Children: much lower than before, but not zero

The EPA’s America’s Children and the Environment report shows the median blood lead level of US children ages 1 to 5 fell to 0.6 µg/dL in 2017–2020, a 96% decrease since 1976–1980. The biggest drop followed the removal of lead from gasoline. The median was higher for children in families below the poverty level (0.8 µg/dL) than for other children (0.6 µg/dL).

What “1 in 40” means

The CDC’s blood lead reference value of 3.5 µg/dL was set at the 97.5th percentile of blood lead in US children ages 1 to 5, using national survey data from 2015 to 2018. By definition, that means about 2.5% of young children, roughly 1 in 40, were at or above 3.5 µg/dL in that survey. It does not mean children below 3.5 are safe. The CDC says the value is a screening tool to find children with more lead than most, and it is not health-based. Our guide to blood lead levels explains the numbers in more detail.

Why there is no single national case count

States report blood lead tests to the CDC, and the CDC publishes those tables for 2017–2022. But the CDC itself warns that this data is not a population-based estimate, is not representative of the US or even of a whole state, and cannot be compared accurately between states because testing and case definitions differ.

Adults: mostly a workplace issue

The CDC’s National Institute for Occupational Safety and Health (NIOSH) tracks adults with blood lead of 10 µg/dL or more through its ABLES program. Among adults at that level whose source was known, about 90% were exposed at work, and the National Institute of Environmental Health Sciences (NIEHS) names jobs such as mining, construction, welding and battery manufacturing. See lead poisoning in adults for more.

Where the risk still comes from

Old paint and dust. The EPA says about three-quarters of US homes built before 1978 still contain some lead-based paint. HUD’s American Healthy Homes Survey II, done in 2018–2019, found lead-based paint in 34.6 million homes and at least one lead-based paint hazard in 29 million. About 3.3 million homes with a hazard had a child under 6 living there.
Water pipes. The EPA estimated in its November 2025 update that about 4 million lead service lines remain across the country. Read more in our guide to lead pipes.
Jobs and hobbies. Most adults with high blood lead were exposed at work.
Products. The CDC lists some imported candies, traditional medicines, toys and jewelry as sources.

What these statistics mean for you

Three practical steps, in line with CDC, EPA and HUD advice:

Test people, not guesses. Most children with lead in their blood have no obvious symptoms; the CDC calls a blood test the best way to know. Ask your doctor; our guide to the lead poisoning test explains how it works.
Find the source. In a pre-1978 home or one with a possible lead service line, testing paint, dust and water shows where lead is.
Get help early. Ask your doctor or local health department.

For risks, sources and who to call, see our lead poisoning guide.

Frequently asked questions

Can lead poisoning kill you?

Yes. Very high levels can cause serious brain injury and death, which is rare in the US today. Far more often, years of exposure raise blood pressure and the risk of heart disease, and the WHO links more than 3.5 million deaths worldwide in 2023 to lead, mostly through the heart and blood vessels.

How many people die from lead poisoning in the US each year?

We found no official yearly count. A 2018 peer-reviewed study estimated about 412,000 deaths a year attributable to lead, mostly from heart disease, in adults exposed in 1988–1994.

How common is lead poisoning in children?

Much less common than in the past: the median level in children ages 1 to 5 fell 96% since 1976–1980. No safe level is known, so ask your child’s doctor about testing.

Which Doctor Treats Lead Poisoning? Who to See and How to Find Them

For most people, the doctor who treats lead poisoning is the one they already have: a child’s pediatrician or an adult’s family doctor, working together with the local health department. When blood lead levels are high, the CDC tells that doctor to bring in specialists, such as a Pediatric Environmental Health Specialty Unit (PEHSU), Poison Control or a medical toxicologist.

Doctor on a phone consultation at a desk in a clinic office

In short: start with your own doctor or your child’s pediatrician and ask for a blood lead test. Your local health department can often test too, and it follows up on high results. Workers exposed on the job can also see an occupational medicine clinic. At higher levels, the CDC’s guidance has the doctor consult a PEHSU or Poison Control, and at the highest levels a medical toxicologist or a pediatrician experienced in lead poisoning, sometimes with a hospital stay. For urgent questions call Poison Control at 1-800-222-1222; for a seizure, collapse or trouble breathing, call 911.

This page sums up what the CDC, ATSDR, NIOSH, OSHA and the specialist networks publish. It is not medical advice; only a provider who knows the patient can decide on care.

Who to see first: your own doctor

The CDC’s advice to parents is simple: if you believe your child has been exposed to lead, talk to your child’s health care provider, who may order a blood lead test. Most children with lead in their blood have no obvious symptoms (see lead poisoning symptoms). Our blood lead test guide explains the finger-prick and blood-draw versions and what a result means.

The CDC’s clinical guidance is written for these providers: it tells them what to do at each blood lead level, from education and repeat tests to reporting, home investigations and specialist referrals. Your regular doctor is not just a gatekeeper; for most people with lead exposure, that doctor manages the follow-up. Our guide to lead screening for children covers when children are usually tested.

For adults, NIOSH, the CDC’s worker-safety institute, says that if you or someone in your household works with lead, tell your doctor, and ask about a blood lead test if your employer does not offer routine testing. See lead testing for adults for who should ask.

Your local health department’s lead program

The CDC says health care providers and most local health departments can test for lead in the blood. The CDC also funds childhood lead poisoning prevention programs run by state and local health departments. When a child’s result is at or above the CDC’s blood lead reference value of 3.5 µg/dL, the CDC tells the doctor to report it to the state or local health department, which may then follow the child, help the family find the source and arrange a home investigation where local rules require one.

What each program offers is set by the state or city, so call your county or city health department and ask for its lead program. Our lead poisoning test page lists other places to get tested.

Lead poisoning specialists

Three kinds of specialists come up in official guidance, working alongside your own doctor.

Pediatric Environmental Health Specialty Units (PEHSU)

The PEHSU network was created in 1998 by ATSDR, the CDC’s agency for toxic substances, with support from the EPA. It has ten regional units based at academic health institutions, each covering a group of states, with experts in pediatrics, environmental medicine and clinical toxicology. According to pehsu.net, pediatric and obstetric providers, public health departments and other health professionals can contact their regional unit for a consultation on children’s or pregnancy-related environmental exposures, lead included. ATSDR says the units also work with parents, schools and community groups.

Note for families: the national PEHSU site says the units do not provide clinical services. Your doctor can consult the regional unit. Find yours on the PEHSU regions page, which lists the states each region covers with phone and email contacts. We could not find a published statement on whether consultations cost anything, so ask your regional unit.

Medical toxicologists

Medical toxicologists are physicians who specialize in poisoning. The CDC’s guidance names them for the highest blood lead levels, where the provider consults “a medical toxicologist or pediatrician with experience in treating lead poisoning” about treatment. The American College of Medical Toxicology (ACMT) runs a public Find a Toxicologist directory that can be filtered by state and by inpatient or outpatient services. Some poison centers are listed in the directory too.

Occupational medicine doctors, for workers

Most adults with high blood lead are exposed at work, according to NIEHS. OSHA’s lead standards require employers to provide medical surveillance, including blood lead tests, without cost to employees who are or may be exposed at or above the action level for more than 30 days a year. The Association of Occupational and Environmental Clinics (AOEC) keeps a clinic directory of member clinics that see workers with job-related illness and people exposed to environmental hazards.

Who to see, when, and how to find them

Who	When to see them	How to find one
Pediatrician or family doctor	First stop for any lead worry, a blood lead test and all follow-up	Your own provider, or ask your health department where to go
Local health department	Testing, follow-up of high results, home investigations where required	Your county or city health department’s lead program
Poison Control	Someone swallowed something that may contain lead, or you have urgent questions	1-800-222-1222, free and confidential, 24/7
PEHSU	Your doctor wants expert advice on a child’s or pregnancy exposure (CDC: at 20 µg/dL and above)	pehsu.net, by region; no clinical care
Medical toxicologist	Very high levels (CDC: 45 µg/dL and above), usually through your doctor or a hospital	ACMT Find a Toxicologist; ask your doctor or Poison Control
Occupational medicine clinic	Lead exposure at work	Your employer’s medical program; AOEC clinic directory
Emergency room / 911	Seizure, collapse, trouble breathing or other severe symptoms	Call 911

What the CDC tells doctors to do at each level

Which specialist joins in depends on the blood lead level. In the CDC’s guidance for children’s providers (dated August 21, 2025), each step includes the ones before it:

Below 3.5 µg/dL: the regular doctor teaches families about lead sources, checks development and diet, and retests based on age and risk.
3.5 to 19 µg/dL: the doctor reports to the health department, takes an exposure history, arranges a home investigation as required locally and schedules follow-up tests.
20 to 44 µg/dL: a full history and exam, and the doctor contacts a PEHSU or Poison Control for guidance.
45 µg/dL and above: the doctor consults a medical toxicologist or a pediatrician experienced in lead poisoning about treatment, and admits the child to a hospital as soon as possible if there are signs or symptoms. The CDC also tells doctors to consider admission when the home is not lead-safe and no lead-free housing is available.

Our blood lead levels page puts these numbers in context, and lead poisoning treatment explains what the CDC and ATSDR say about care, including why there is no home treatment.

When to call Poison Control or 911

Poison Control, at 1-800-222-1222, connects you to your local poison center, where trained nurses, pharmacists or doctors answer; HRSA says the call is free, confidential and open 24 hours a day. Call if a child swallowed a paint chip, a fishing weight or anything else that might contain lead, or if you have urgent questions. For a seizure, collapse or trouble breathing, call 911. MedlinePlus (National Library of Medicine) also lists vomiting or seizures as reasons to call 911.

What to bring to the appointment

Test results: every blood lead result you have, with dates, and whether each was a finger-prick or a blood draw from a vein.
Home information: the year your home was built (paint before 1978 may contain lead), any recent renovation, peeling paint, known lead pipes, and any home or water test results. See lead paint testing and lead in water testing.
Products: names or photos of imported spices, foods, candies, remedies, cosmetics, pottery or toys you use, or the items themselves if the doctor asks. See lead in household items.
Work and hobbies: jobs and hobbies of everyone in the home, since NIOSH notes lead dust can come home on work clothes and shoes.

Questions to ask the doctor

Was this a finger-prick or a venous test, and does it need to be confirmed?
When should the next blood lead test be?
Will you report this to the health department, and will someone check our home?
Should other people in the household be tested?
Do you plan to consult a PEHSU, Poison Control or a medical toxicologist?

For what usually happens over the following months, see lead poisoning recovery.

Insurance and Medicaid

The CDC says many private insurance policies cover the cost of blood lead testing, and for children enrolled in Medicaid the cost is covered by the Centers for Medicare and Medicaid Services. A 2016 CMS bulletin states that all children enrolled in Medicaid are required to receive blood lead screening tests at 12 and 24 months, and any child aged 24 to 72 months with no record of a previous test must receive one. The same bulletin says Medicaid can reimburse lead investigations in the home of a child with elevated blood lead. Workers covered by OSHA’s lead standards get medical surveillance from their employer at no cost. Ask your insurer about specialist visits.

Frequently asked questions

What kind of doctor treats lead poisoning?

Usually a pediatrician or family doctor, with the local health department. At higher levels the CDC tells that doctor to consult a PEHSU or Poison Control, and at the highest levels a medical toxicologist or a pediatrician experienced in lead poisoning.

Is there a lead poisoning specialist near me?

Check ACMT’s Find a Toxicologist directory, your regional PEHSU on pehsu.net, and the AOEC clinic directory if the exposure is from work. Your doctor or health department can also refer you.

Can I call a PEHSU myself?

PEHSUs mainly advise health professionals, but ATSDR says they also work with parents, and each region lists a phone and email. They do not provide clinical care.

Should I go to the emergency room for lead exposure?

Call 911 for severe symptoms such as a seizure, collapse or trouble breathing. Otherwise, call Poison Control at 1-800-222-1222 or your doctor; they will tell you whether you need to be seen right away.

Does insurance pay for a blood lead test?

The CDC says many private plans cover it, and Medicaid covers it for enrolled children. OSHA requires employers to provide it free to covered workers.

Lead Poisoning in Adults: Symptoms, Signs and When to Get Tested

Lead poisoning in adults most often shows up as vague, everyday complaints: headaches, tiredness, joint and muscle pain, stomach pain or constipation, trouble concentrating or remembering, mood changes and higher blood pressure. Many adults with lead in their blood have no symptoms at all, which is why the CDC and its toxic substances agency, ATSDR, say a blood lead test is the way to know.

Nurse checking an adult's blood pressure in a clinic

In short: lead affects almost every system in an adult’s body. Official sources link it to high blood pressure, nervous system problems (headache, fatigue, poor concentration, memory loss, depression and irritability, tingling in the hands or feet), joint and muscle pain, stomach pain, kidney damage, anemia, and fertility problems in men and women, including lower sperm counts and abnormal sperm. In pregnancy, lead is linked to miscarriage and to babies born too early or too small. At very high levels lead can injure the brain (encephalopathy) and cause seizures, coma and death. Symptoms alone cannot tell you whether lead is the cause; a blood lead test ordered by a health care provider can. For urgent questions call Poison Control at 1-800-222-1222, and call 911 for severe symptoms such as seizures.

This page explains what the CDC, NIOSH, ATSDR, NIEHS, OSHA, WHO and MedlinePlus say about lead poisoning symptoms in adults. It is not medical advice. Only a health care provider can decide what your symptoms mean and what to do next. For symptoms in children, see our main lead poisoning symptoms guide; for the bigger picture, start at lead poisoning.

Common signs of lead poisoning in adults

Adults absorb less of the lead they swallow than young children do, the WHO notes, and ATSDR says adults show nervous system symptoms at higher blood lead levels than children. But lead builds up over months and years, mostly in bone, and the signs tend to creep in slowly. Here is what official sources list, grouped the way you might notice them:

High blood pressure. NIOSH lists increased blood pressure among the effects of long-term exposure, the WHO names a higher risk of high blood pressure as a long-term harm in adults, and NIEHS says blood lead levels below 10 µg/dL are associated with increases in blood pressure and hypertension.
Joint and muscle pain. ATSDR lists muscle aches at low exposure and joint pain (arthralgia) at moderate exposure. OSHA says workers above 40 µg/dL begin to have joint pain and muscle pain (myalgia).
Headaches and fatigue. Headache, exhaustion and weakness are on NIOSH’s list for high short-term exposure; ATSDR lists mild fatigue at low exposure and general fatigue and headache at moderate exposure; OSHA adds sleep disturbance.
Stomach pain and constipation. NIOSH lists stomach pain, nausea and constipation for long-term exposure, and MedlinePlus says stomach pain and cramping are usually the first sign of a high, toxic dose. ATSDR notes that severe cramping (lead colic) can be mistaken for appendicitis.
Memory and concentration problems. NIOSH lists memory loss, distraction and forgetfulness. ATSDR lists difficulty concentrating, and in lead-exposed workers impaired concentration, slower reaction time and reduced hand dexterity.
Mood changes. NIOSH names depression, irritability and altered moods or behavior; ATSDR adds increased nervousness and lethargy.
Tingling or pain in the hands and feet. NIOSH lists pain or tingling in the hands or feet. ATSDR describes slowed nerve conduction and wrist weakness (“wrist drop”) as late signs in workers with long, high exposure.
Fertility problems. NIOSH lists fertility problems in men and women. ATSDR says occupational exposure may lower total sperm counts and increase abnormal sperm, and NIEHS links blood lead above 15 µg/dL to lower sperm counts and motility and to delayed conception. ATSDR also lists decreased libido and impotence among symptoms in exposed workers.
Pregnancy loss and early birth. The CDC says lead in a pregnant person’s blood raises the risk of miscarriage and of a baby being born too early or too small; the WHO says lead exposure in pregnancy can cause reduced fetal growth and preterm birth.

Some effects cause no symptoms you would notice. Kidney damage and anemia, for example, usually show up only in blood and urine tests. ATSDR adds that lead-induced anemia in adults is not common and appears only when blood lead has been high for a long time.

Lead toxicity in adults, system by system

ATSDR’s course for clinicians says lead serves no useful purpose in the body and can affect every organ system. This table sums up what each agency lists for adults.

Body system	Symptoms or effects in adults	Source
Heart and blood vessels	Increased blood pressure and hypertension; possible links to heart disease and stroke	NIOSH, NIEHS, WHO, ATSDR
Brain and nerves	Headache, fatigue, memory loss, forgetfulness, difficulty concentrating, tremor, tingling or pain in hands and feet; at very high levels encephalopathy, seizures, coma	NIOSH, ATSDR, OSHA, MedlinePlus
Mood and behavior	Depression, irritability, altered moods, nervousness, lethargy	NIOSH, ATSDR
Muscles and joints	Muscle aches (myalgia), joint pain (arthralgia), weakness	ATSDR, OSHA, NIOSH
Digestive system	Stomach pain, nausea, vomiting, constipation, loss of appetite, weight loss, metallic taste; severe cramping (colic) at high levels	NIOSH, ATSDR, MedlinePlus
Kidneys	Decreased kidney function, kidney damage	NIEHS, WHO, NIOSH
Blood	Anemia (uncommon in adults; seen with long, high exposure)	ATSDR, NIOSH, WHO
Male reproduction	Lower sperm counts, abnormal sperm, reduced motility; decreased libido, impotence	ATSDR, NIEHS, OSHA
Female reproduction and pregnancy	Delayed conception; miscarriage; baby born too early or too small	NIEHS, ATSDR, CDC, WHO
Other	Decreased lung function, bone or tooth loss, more infections	NIOSH

For how these effects play out over years, and which ones can last, see effects of lead poisoning.

How symptoms change with the level of exposure

ATSDR describes a “continuum” of signs and symptoms that tend to grow as exposure grows. It stresses that this is only a guide: symptoms vary from person to person, and no exact blood lead number can be attached to each stage.

Lowest exposure: the person may seem to have no symptoms, while subtle effects on thinking, learning and memory are possible.
Low exposure: irritability, lethargy, mild fatigue, muscle aches or tingling, occasional stomach discomfort.
Moderate exposure: joint pain, constipation, difficulty concentrating and muscles that tire easily, stomach pain, general fatigue, headache, tremor, vomiting, weight loss.
High exposure: intermittent severe stomach cramps (colic); encephalopathy that can quickly lead to seizures, a change in consciousness, coma and death; weakness or paralysis.

ATSDR says symptomatic lead poisoning in adults generally comes with blood lead levels of 40 to 60 µg/dL, and severe toxicity is often seen at 100 µg/dL or more. OSHA’s health-effects page for workers gives a similar picture:

Adult blood lead level	What OSHA says is associated
As low as 10 µg/dL (chronic exposure)	Impaired kidney function, high blood pressure, nervous system and behavioral effects, cognitive decline later in life
Above 20 µg/dL	Subtle effects on thinking; effects on sperm and semen quality; delayed conception
20 to 40 µg/dL	Cognitive aging, poorer hand-eye coordination, slower reactions, attention problems
Above 40 µg/dL	Symptoms begin: headache, fatigue, sleep disturbance, joint pain, muscle pain, loss of appetite, constipation
Above 60 µg/dL (much less common today)	Convulsions, coma and in some cases death; anemia, nerve damage, kidney scarring, severe stomach cramps

The point to take from both sources: by the time an adult feels clearly unwell from lead, blood lead is usually well above the levels where quieter harm, such as rising blood pressure or reduced kidney function, has already been found. Our blood lead levels guide explains what the numbers mean.

Why symptoms are often vague or missing

NIOSH says lead symptoms are similar to those of other illnesses, may develop slowly and can be overlooked. ATSDR notes that many people with lead poisoning have no symptoms, and that lead is often missed or misdiagnosed because tiredness, headaches, stomach pain and high blood pressure have so many other causes.

The NIEHS adds that health effects in adults have been found at blood lead levels below 5 µg/dL, such as decreased kidney function, and the WHO says there is no known safe blood lead concentration. In other words, feeling fine does not mean lead is doing nothing, and feeling unwell does not mean lead is the cause.

Very high levels: encephalopathy and seizures

Severe lead poisoning is rare in US adults today, but it still happens, mostly through work or contaminated products. MedlinePlus lists the signs of very high lead levels as vomiting, internal bleeding, a staggering walk, muscle weakness, seizures and coma. ATSDR describes lead encephalopathy (swelling and injury of the brain) as able to progress suddenly to seizures, coma and death, and says warning signs that can come first include dullness, irritability, memory loss, muscle tremor and a poor attention span.

These are emergencies. MedlinePlus says to call 911 right away for severe symptoms such as vomiting or seizures.

Where adults are exposed to lead

The NIEHS says most adults with elevated blood lead were exposed at work. The main sources, briefly:

Jobs: renovation, painting and demolition of older buildings, bridge and steel-structure work, battery making and recycling, smelting and foundries, welding and cutting, mining, firing ranges, radiator repair.
Hobbies: casting bullets or fishing weights, target shooting, stained glass, lead glazes and pigments.
Home renovation in a house built before 1978, when lead paint was still sold for homes.
Imported products: some traditional or Ayurvedic remedies, cosmetics such as kohl, and recalled spices, including cinnamon.
Drinking water from lead service lines, lead solder or older brass fixtures.

NIOSH also warns that workers can carry lead dust home on clothes, shoes and hair, putting children and pregnant family members at risk. Our guide to lead testing for adults covers each of these in detail, including what OSHA requires employers to provide.

Symptoms are not a diagnosis: a blood lead test is

No list of symptoms can confirm or rule out lead poisoning. The CDC calls a blood lead test the best way to assess a person’s exposure, and ATSDR tells clinicians that lead can only be diagnosed early if they suspect it behind common, nonspecific complaints. The test uses a blood sample drawn by a health care provider and sent to a laboratory. Home swab kits test surfaces like paint, not people.

If you have symptoms on this page and a possible source of lead, tell your doctor about your job, hobbies, home and any imported remedies, cosmetics or spices, and ask whether a blood lead test makes sense. Our lead poisoning test guide explains how the test works.

When to call a doctor, Poison Control or 911

Situation	Who to call
Seizures, repeated vomiting, collapse or trouble breathing	911 right away
Symptoms you think may be from lead, or you swallowed or breathed something that may contain a lot of lead	Poison Control, 1-800-222-1222 (free and confidential, 24/7)
Vague symptoms and a possible ongoing source (work, hobby, renovation, remedy, water)	Your health care provider or local health department, to ask about a blood lead test
You work with lead	Your employer’s medical program and your own doctor; tell your family’s doctors too
You are pregnant or planning a pregnancy and may be exposed	Your prenatal care provider

MedlinePlus notes that for suspected low-level exposure an emergency room visit is usually not needed unless the exposure was a high dose.

What happens after a high result

Treatment is a medical decision: your doctor decides, often with the local health department or a medical toxicologist. The first step official sources describe is always the same, finding the source and stopping the exposure. Do not try supplements, “detox” products or anything sold to remove lead from the body. Our lead poisoning treatment page explains what doctors consider, lead poisoning recovery covers what to expect afterwards, and lead poisoning statistics has the national numbers.

Frequently asked questions

What are the first signs of lead poisoning in adults?

Often there are none. When symptoms appear, ATSDR lists irritability, tiredness, muscle aches or tingling and occasional stomach discomfort among the earliest. MedlinePlus says stomach pain and cramping are usually the first sign of a high, toxic dose.

Can lead poisoning cause high blood pressure?

Yes. NIOSH, NIEHS, ATSDR and the WHO all link lead to higher blood pressure in adults, and NIEHS says the association is seen at blood lead levels below 10 µg/dL. High blood pressure has many causes, so only testing can show whether lead plays a part.

Can lead affect fertility in men and women?

Yes. ATSDR says occupational exposure may lower sperm counts and increase abnormal sperm, and NIEHS links blood lead above 15 µg/dL to lower sperm counts and motility and to delayed conception. In pregnancy, the CDC links lead to miscarriage and to babies born too early or too small.

Can I have lead poisoning without symptoms?

Yes. ATSDR says many people with lead poisoning have no symptoms, and NIEHS reports effects such as decreased kidney function at low levels. A blood lead test is the only way to know.

Is lead poisoning in adults the same as lead toxicity?

The terms are used interchangeably. ATSDR’s clinician course is titled “Lead Toxicity,” and it covers the same symptoms and effects described on this page.

Lead Poisoning in Dogs and Cats: Signs, Sources and What to Do

Lead poisoning in dogs and cats is uncommon, but it does happen, and the signs are easy to mistake for an upset stomach or another illness. Veterinary sources describe vomiting, diarrhea, loss of appetite, belly pain, lethargy, behavior changes, wobbliness, tremors and seizures, usually after a pet swallows old paint chips or dust, a lead object such as a fishing sinker, or dust from a home renovation.

A cat resting near a sunny window in an older home

In short: if you think your dog or cat has swallowed something with lead or shows these signs, call your veterinarian right away, or the ASPCA Animal Poison Control Center at (888) 426-4435, which answers 24 hours a day, 365 days a year; the ASPCA says a consultation fee may apply. Do not make your pet vomit unless a professional tells you to. A vet confirms lead poisoning with a blood test and decides on treatment. Because pets and young children are often exposed to the same lead, a poisoned pet is also a reason to ask your doctor about testing the children in your home.

This page summarizes what the ASPCA Animal Poison Control Center, the Merck Veterinary Manual and veterinary schools publish. It is not veterinary advice; only your vet can examine and treat your pet.

How common is lead poisoning in pets?

Not very. The ASPCA’s poison control primer for veterinarians says lead toxicity is not a common issue in dogs and cats, but that cases do happen. In 2015, as reported by the AVMA’s news service, the ASPCA center handled 65 lead cases out of about 181,000 animal poisoning cases. The Merck Veterinary Manual lists dogs, cattle and pet birds as the animals in which lead poisoning is most common, and notes that young animals absorb lead more readily, so young age, a habit of chewing or eating non-food items, and easy access to lead are the key risk factors.

Rare does not mean unimportant. Lead poisoning can look like many other illnesses, and veterinary researchers point out that it can be missed unless someone thinks to test for it.

Signs of lead poisoning in dogs and cats

The ASPCA and the Merck Veterinary Manual describe two patterns. Signs mostly involve the stomach and gut and the nervous system:

Type of exposure	Signs veterinary sources list
Sudden (acute), such as swallowing a lead object or a large amount of paint	Not eating, vomiting, belly pain, behavior changes, a wobbly or unsteady walk (ataxia), tremors, overexcitement and seizures that come and go
Long-term (chronic), such as repeated paint dust or chips	Vaguer signs: belly discomfort, vomiting, diarrhea, not eating, lethargy, weight loss, anemia, behavior changes, occasional seizures, and in some dogs an enlarged, weak esophagus (megaesophagus), which is rarely reported in cats

The Merck Veterinary Manual says lead colic, a painful belly, can occur in all species, and that lead poisoning can resemble other nervous system and digestive diseases, so a vet may need to rule those out. Cornell University’s Feline Health Center lists vomiting, seizures and an unsteady gait among poisoning signs in cats that call for prompt action.

None of these signs is specific to lead. A dog with vomiting and diarrhea most likely has something else, but if there is old paint, renovation dust or a lead object in its life, tell your vet.

Puppies and young animals

Young animals are at higher risk on two counts. They chew and swallow things more, and, according to the ASPCA’s primer, a young animal may absorb as much as half of the lead it swallows, compared with roughly 5 to 15 percent in adults. If a puppy has been chewing on old windowsills, painted furniture or anything metal and heavy, mention it to your vet even if the puppy seems well.

Signs in cats

Cats rarely chew on objects the way puppies do. The Merck Veterinary Manual reports that cats have been poisoned by grooming dust off their fur after lead-painted woodwork was sanded, which turns dust on the coat into lead in the stomach. Cornell’s Feline Health Center names lead among the frequent causes of poisoning in cats and says they are exposed through many sources, including paint chips, linoleum and dust in older homes. The Merck manual notes there is no good information on a toxic dose for cats, one more reason to call a professional rather than guess.

Common sources of lead for pets

Old paint, chips and dust. The Merck Veterinary Manual says house paint made before 1978 can contain high concentrations of lead, and that a chip the size of a thumbnail can hold 50 to 200 mg of lead. See lead paint testing.
Home renovation. Sanding and scraping old paint spreads fine dust that pets walk through and lick off their paws and fur. The ASPCA’s poison control director has said remodeling is the most common situation in which the center sees pets exposed to lead.
Lead weights. Fishing sinkers and other lead weights, and lead shot. Some older curtain and drapery hem weights are also made of lead; a curtain weight has poisoned a child, according to a case report indexed by the NIH’s National Library of Medicine.
Other household items. The Merck manual and the ASPCA also list linoleum, solder, toys, bullets, putty, caulk, ceramic glazes on food and water bowls, and the foil covers on some wine corks.
Soil. Dogs that dig near older painted buildings or busy roads can swallow lead in soil. See dust and soil testing.

What to do if you suspect lead poisoning

Call your veterinarian or an emergency vet clinic right away. If your pet is having a seizure, collapsing or struggling to breathe, go straight to an emergency clinic.
Or call the ASPCA Animal Poison Control Center: (888) 426-4435. It is open around the clock, every day of the year. The ASPCA says a consultation fee may apply.
Do not make your pet vomit unless a veterinarian or poison control expert tells you to, as Cornell’s Feline Health Center advises.
Bring what you can. A sinker, chip or package, or a photo of it, and a note of when it happened and what signs you have seen.
Keep other pets and children away from the area until the source is found.

Do not give your pet any medicine, supplement or home remedy for lead. Only a vet can decide what is safe for your animal.

How vets diagnose lead poisoning

According to the Merck Veterinary Manual, the diagnosis is made by measuring lead in a blood sample, and only a small amount of blood is needed. X-rays can show lead objects in the stomach or intestines, and some blood smear findings can point toward lead but do not confirm it. Treatment, if needed, is decided by the veterinarian based on the pet’s signs and test results, and it always includes removing the lead source from the pet’s surroundings so the animal is not exposed again. Follow-up blood tests are part of that care.

Your pet as an early warning for your family

The Merck Veterinary Manual notes that dogs and cats can be sentinels for human exposure: the paint dust, soil or object that poisoned a pet may be reaching a toddler too. The CDC says most children with lead in their blood have no obvious symptoms, so if your pet is diagnosed, ask your child’s doctor or your local health department about a blood lead test, and read lead and children. For people, the number is Poison Control at 1-800-222-1222, and our guides to lead poisoning symptoms and lead poisoning explain what to watch for.

How to protect your dog or cat from lead

Know your home. If it was built before 1978, test for lead paint before you sand, scrape or remodel, and use a certified, lead-safe contractor. See lead-safe renovation and our professional directory.
Keep pets out of work areas during renovation and until cleanup is finished, since cats groom dust off their coats and dogs lick their paws.
Wet-clean dust on floors and windowsills, and wash pet bedding, toys and bowls often.
Store fishing tackle, ammunition and lead weights out of reach, and check old curtains for hem weights if your pet chews fabric.
Use bowls made for food. Skip old or decorative glazed ceramics of unknown origin; see lead in pottery and dishes.
Watch the yard. Discourage digging along the walls of older painted buildings, and test soil if you are unsure.

Frequently asked questions

What are the first signs of lead poisoning in a dog?

Veterinary sources most often list not eating, vomiting, belly pain and behavior changes, and with more severe exposure, a wobbly walk, tremors or seizures. These signs are not specific to lead, so call your vet.

My dog swallowed a fishing sinker. What should I do?

Call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 right away, even if your dog seems fine. Don’t make it vomit unless told to. A vet may take an X-ray to find the sinker.

Can cats get lead poisoning from dust?

Yes. The Merck Veterinary Manual reports cats poisoned by grooming dust from sanded lead-painted woodwork off their fur. Keep cats out of renovation areas in older homes.

Is the ASPCA poison hotline free?

The ASPCA says a consultation fee may apply; it does not publish the amount on its main page. Your own vet is also a good first call.

Can I test my pet for lead at home?

No. Lead in an animal is measured with a blood test done by a vet. Home swab kits are made for surfaces such as paint, not for pets or people, and EPA recognizes only certain kits for certain surfaces.

Effects of Lead Poisoning on Children and Adults

The effects of lead poisoning depend on age, how much lead and for how long, but official health agencies agree on the main ones. In children, lead harms the developing brain and nervous system, with effects on learning, attention and behavior; in adults, it is linked to higher blood pressure, kidney damage and fertility problems, and some effects in both can be permanent.

An adult having blood pressure checked by a nurse

In short: the CDC says no safe blood lead level in children has been identified, and the World Health Organization says there is no known safe blood lead concentration. Even low levels in children are associated with lower IQ scores and school achievement and with attention and behavior problems, according to the CDC and NIEHS. In adults, NIEHS links levels below 10 µg/dL to higher blood pressure and reduced kidney function, and NIOSH lists anemia, nerve and brain damage and infertility at high exposure. Because damage may not be reversible, prevention and early testing matter most. If you are worried, talk to a doctor or your local health department, or call Poison Control at 1-800-222-1222.

This page explains what the CDC, the National Institutes of Health (through NIEHS and its National Toxicology Program), NIOSH and WHO publish. It is not a diagnosis or medical advice. For an overview of the topic, start at our lead poisoning hub.

Lead toxicity: why lead harms the body

Lead toxicity is the medical term for the harm lead does once it is inside the body. Lead travels in the blood, reaches the brain, kidneys and other organs, and is stored in bones and teeth, the WHO explains. Stored lead can move back into the blood years later, for example during pregnancy, and reach a developing baby.

Doctors measure exposure with a blood lead test, reported in micrograms per deciliter (µg/dL). The CDC’s blood lead reference value for children is 3.5 µg/dL. That number marks the top 2.5% of US children aged 1 to 5; it is a screening tool, not a line below which lead is harmless.

Effects of lead on children

Children are the main concern for three reasons the CDC and WHO describe: they put hands and objects in their mouths, so they swallow more dust and soil; their bodies absorb more of the lead they swallow than adults do; and their brains are still developing. Children under 6 are the most likely to be exposed, the CDC says.

The CDC lists these effects of lead exposure in children:

Damage to the brain and nervous system
Slowed growth and development
Learning and behavior problems
Hearing and speech problems

The CDC adds that these can show up as lower IQ, a shorter attention span and doing less well in school. The WHO describes reduced attention span and increased antisocial behavior, and says lead exposure in children also causes anemia, high blood pressure, kidney problems and harm to the immune and reproductive systems.

Most of this happens quietly. The CDC says most children with lead in their blood have no obvious immediate symptoms, which is why testing matters more than watching for signs. Our lead poisoning symptoms guide lists the signs that do appear, mostly at higher levels, and our lead and children guide covers screening ages and prevention.

Effects at low levels

NIEHS, part of the NIH, summarizes the research by blood lead level. It says health effects in children are found at levels below 5 µg/dL and may include lower IQ scores and academic achievement, and that levels at or below 10 µg/dL are associated with more behavioral effects and delayed puberty. The National Toxicology Program’s 2012 review of low-level lead concluded there is evidence of harm in both children and adults below 10 µg/dL and, for some effects, below 5 µg/dL.

These are associations found across many studies of groups of people. They describe risk across a population; they cannot predict what will happen to one particular child. A child’s doctor is the right person to talk to about a specific result.

Effects at very high levels

At very high levels, lead can cause severe illness. The NIH’s MedlinePlus lists vomiting, a staggering walk, muscle weakness, seizures and coma. The WHO says children who survive severe lead poisoning may be left with permanent intellectual disability and behavior disorders. These are medical emergencies: call 911.

Effects of lead on adults

Most adults with high blood lead are exposed at work, according to NIEHS, in jobs such as construction, mining, welding and battery manufacturing. Others are exposed through home renovation, hobbies or contaminated products.

Body system	What official sources say
Heart and blood pressure	NIEHS: levels below 10 µg/dL are associated with increases in blood pressure; above 15 µg/dL with cardiovascular effects. WHO: increased risk of high blood pressure and cardiovascular problems. NIOSH lists heart disease.
Kidneys	NIEHS: levels below 10 µg/dL are associated with decreased kidney function, and even below 5 µg/dL may decrease it. WHO and NIOSH list kidney damage.
Brain and nerves	NIOSH: high exposure may cause neurologic and brain damage; long-term exposure can bring depression, irritability, mood changes, distraction and forgetfulness, and pain or tingling in the hands or feet.
Reproduction	NIOSH: infertility in both men and women. NIEHS links levels above 15 µg/dL to fertility problems.
Blood	NIOSH and ATSDR: anemia.
Other	NIOSH also lists hearing damage, decreased lung function, bone or tooth loss and more infections, and says lead is possibly linked to cancer.

NIOSH notes that these effects are the same whether lead is breathed in, swallowed or absorbed through the skin, that symptoms look like those of other illnesses and may develop slowly, and that very high exposure can kill. If you work with lead, tell your doctor.

Effects during pregnancy

Lead crosses the placenta. The CDC says lead stored in a mother’s bones can be released into the blood during pregnancy, and that lead exposure in pregnancy can raise the risk of miscarriage, of a baby being born too early or too small, and of harm to the baby’s brain, kidneys and nervous system. NIEHS says maternal blood lead levels even below 5 µg/dL are associated with reduced fetal growth, and the WHO lists reduced fetal growth and preterm birth. If you are pregnant and think you may have been exposed, the CDC’s advice is to talk to your health care provider.

Long-term effects of lead poisoning

The official wording here is careful, and so are we. What the agencies say:

CDC: “The effects of lead poisoning can be permanent and disabling.”
WHO: lead can permanently affect children’s brain development, and lead causes long-term harm in adults, including increased risk of high blood pressure.
NIEHS: many effects are permanent, and research suggests some psychological effects of childhood exposure may not appear until adulthood. NIEHS-funded research has also linked early-life lead exposure with psychiatric disorders and substance abuse.
WHO, worldwide: citing estimates from the Institute for Health Metrics and Evaluation, more than 3.5 million deaths in 2023 were attributed to lead exposure, mainly through effects on the heart and blood vessels.

A few cautions help read this research well. Many long-term findings come from studies that follow groups of people over time, and they show links, not certainty for any one person. Global death estimates are models, and they include countries with far higher exposure than the US. And lead stored in bone means that exposure in the past can still matter today, which is one reason doctors ask about old jobs, hobbies and homes.

Can the effects be reversed?

Blood lead levels can come down once the source is removed, and doctors can treat very high levels. But treatment does not undo damage that has already happened, and the CDC and WHO both describe some effects as permanent. That is why the CDC’s follow-up for children includes early educational services and developmental checks alongside removing the lead. Our guide to lead poisoning treatment explains what doctors and health departments do at each blood lead level.

Why prevention matters most

Because damage may be permanent and often has no symptoms, the CDC’s approach is to remove lead hazards before a child is exposed, which it calls primary prevention. In most US homes that means:

Old paint and dust. Homes built before 1978 probably contain lead-based paint, the CDC says, and peeling paint and renovation dust are the most common hazards. See lead paint testing and dust and soil testing.
Water. Lead pipes, solder and some brass fixtures can add lead to tap water. See lead in water testing.
Products. Some imported spices, candies, remedies, cosmetics, pottery, toys and jewelry. See lead in household items.
Work and hobbies. Lead dust carried home on clothes, shoes and hair.

Our guide to lead poisoning causes and prevention covers each source and the CDC and EPA steps in detail. When a home needs inspection or repair, use a certified professional from our directory.

Frequently asked questions

What are the long-term effects of lead poisoning?

In children, official sources describe lasting effects on learning, attention, behavior and development; in adults, higher blood pressure, heart and kidney problems and fertility effects. The CDC says effects can be permanent. How a specific person is affected depends on the level and length of exposure.

Is lead toxicity the same as lead poisoning?

The terms are used for the same problem: harm from lead in the body. Health agencies also talk about lead exposure, meaning any lead taken in, since no safe level has been identified in children.

Can a small amount of lead cause harm?

NIEHS says health effects in children are found below 5 µg/dL, and the CDC says no safe level in children has been identified. That is why doctors take any detectable level seriously and look for the source.

Do adults recover from lead exposure?

Blood levels fall once exposure stops, but lead stored in bone can stay for years, and some effects may last. An adult with possible exposure should talk to a doctor, who can order a blood test and advise on follow-up.

How do I know if my child has been affected?

Only a blood test shows exposure. Ask your child’s doctor or your local health department. If your child may have swallowed something with lead, call Poison Control at 1-800-222-1222; for severe symptoms such as a seizure, call 911.

Lead Poisoning Treatment: How Doctors Manage High Blood Lead

Lead poisoning treatment starts with finding the lead and getting the person away from it. For most children and adults with lead in their blood, the CDC’s guidance for health care providers centers on removing the source, repeat blood tests, a healthy diet and close follow-up, with medicine to pull lead from the body (chelation) kept for very high levels and given only by medical professionals.

A health department nurse visiting a family at home

In short: there is no home treatment for lead poisoning. If a blood test shows lead, a doctor and often the local health department will look for where it came from, schedule follow-up tests, check diet and development, and in some cases send an inspector to the home. At very high levels, the CDC tells providers to consider hospital care and to consult a medical toxicologist about treatments such as chelation. If you are worried about lead exposure, call your doctor, your local health department or Poison Control at 1-800-222-1222. Call 911 for severe symptoms such as a seizure.

This page explains what the CDC and its toxic-substances agency ATSDR publish for health care providers. It is not medical advice, and it is not a plan you can follow at home. Only a health care provider who knows the patient can decide on care.

Step one: find the lead and remove it

Lead does not leave the body while new lead keeps coming in. That is why every level of the CDC’s recommended actions includes looking for the source. The CDC tells parents that when a child’s blood lead level is above its reference value, follow-up services can include finding and removing lead from the child’s environment, a diet high in iron and calcium, early educational services and follow-up blood testing. The CDC also describes primary prevention, removing lead hazards from the environment before a child is exposed, as the most effective way to protect children. Our lead poisoning hub sums up what the CDC, NIEHS and WHO say about why.

ATSDR, the CDC’s sister agency for toxic substances, says medical and environmental steps should happen at the same time to best protect a child, and that providers should start a prompt investigation for the source of exposure. In practice, the source is often in the home: deteriorating paint and the dust it makes, water from lead pipes, bare soil, a parent’s work clothes, or an imported spice, remedy or cosmetic. Our guides to lead paint testing, lead in water testing, dust and soil testing and lead in household items explain how each one is checked.

Do not try to strip or sand old paint yourself to “get rid of” the lead. The EPA warns that renovation can create large amounts of lead dust, and that lead abatement should be done by certified professionals. Find one through our lead professional directory.

What the CDC recommends at each blood lead level

The CDC publishes a table of recommended actions for children’s blood lead levels, measured in micrograms per deciliter (µg/dL). Its blood lead reference value is 3.5 µg/dL, the level that marks the top 2.5% of US children aged 1 to 5. The reference value is a screening tool, not a safe line: the CDC says no safe blood lead level in children has been identified. Each row below includes all the actions in the rows above it. We summarize the CDC’s provider guidance as published on its “Recommended Actions Based on Blood Lead Level” page (dated August 21, 2025).

Blood lead level (µg/dL)	What the CDC tells providers to do
Below 3.5	Teach families about lead sources and prevention; check development, diet and nutrition at well-child visits; repeat testing at intervals based on age and risk.
3.5 to 19	All of the above, plus: report to the state or local health department; take an environmental exposure history; arrange an environmental investigation as required where you live; test for and treat iron deficiency; review diet with a focus on calcium and iron; check development and refer for services as needed; schedule follow-up blood tests.
20 to 44	All of the above, plus: a full history and physical exam looking for signs of lead exposure; arrange or refer for an environmental investigation and lead hazard reduction; consider an abdominal X-ray to look for swallowed lead chips or objects; consult a Pediatric Environmental Health Specialty Unit (PEHSU) or Poison Control.
45 or higher	All of the above, plus: a detailed neurological exam; abdominal X-ray and, if needed, bowel decontamination; hospital admission if the child has symptoms, or if the home is not lead-safe or the source is unknown; consultation with a medical toxicologist or a pediatrician experienced in lead poisoning about decontamination or chelation.

A finger-prick (capillary) result at or above the reference value is confirmed with a blood draw from a vein, because lead on the skin can make a finger-prick read high. The higher the first result, the sooner the CDC wants that confirmation: within 3 months for 3.5 to 9 µg/dL, within 1 month for 10 to 19, within 2 weeks for 20 to 44, and within 48 hours for 45 or more. Our blood lead test guide explains the two kinds of test and what a result means.

Case management and the health department

Once a child’s blood lead level is at or above the reference value, the CDC tells providers to report it to the state or local health department. Many health departments then run what is called case management: a nurse or case worker follows the child, helps the family find and fix the source, and makes sure repeat tests happen. What the health department does, and at what level, is set by each state or city. The CDC’s guidance says environmental investigations should be arranged “as required,” because the rules differ from place to place. It also notes that in housing covered by HUD’s Lead Safe Housing Rule, an investigation may not be triggered below 5 µg/dL.

An environmental investigation usually means a trained inspector or risk assessor visits the home to look for paint, dust, soil and water hazards, and asks about jobs, hobbies, foods, spices, remedies and cosmetics. If you rent, tell your health department and your landlord; if you own, the investigator’s report tells you which hazards need professional work. For the difference between an inspection and a risk assessment, see lead paint inspection.

Nutrition: what the CDC says

The CDC’s advice on food is short and specific: for a child with a blood lead level above the reference value, it lists “a diet high in iron and calcium” among the follow-up services a doctor may recommend. For providers, it adds testing for and treating iron deficiency, reviewing the child’s diet with a focus on calcium and iron, and referring families to nutrition programs such as WIC.

A good diet supports a child’s health while the source is removed. It is not a treatment that removes lead, and it does not make lead exposure safe. Do not give a child iron, calcium or any other supplement for lead unless the child’s own doctor tells you to; the CDC’s guidance has the provider test for iron deficiency first.

Chelation: only for high levels, only by medical professionals

Chelation therapy uses prescription medicine that binds to lead so the body can get rid of it. The CDC says that if a child does have high levels of lead in the blood, they may receive chelation therapy, and its provider guidance places it at 45 µg/dL and above, decided together with a medical toxicologist or a pediatrician experienced in lead poisoning. ATSDR adds that 45 µg/dL is a guideline rather than a fixed threshold, that professional judgment should guide the decision for a child or an adult, and that chelation is not risk free.

We describe chelation only so you know what a doctor may talk about. It is a hospital or specialist treatment. Products sold online as “detox” or “chelation” for lead are not the same thing, and no official source we use recommends them. If anyone suggests a home lead detox, talk to your doctor or call Poison Control at 1-800-222-1222 first.

Follow-up blood tests

Treatment is measured with repeat blood tests. The CDC’s schedule for children after a confirmed venous result is:

Venous blood lead level (µg/dL)	Early follow-up	Later follow-up, once levels are falling
3.5 to 9	3 months	6 to 9 months
10 to 19	1 to 3 months	3 to 6 months
20 to 44	2 weeks to 1 month	1 to 3 months
45 or higher	As soon as possible	As soon as possible

The CDC notes that blood lead levels can change with the seasons, and that more time outdoors in summer may call for more frequent checks. ATSDR lists reasons a level may rise again: a source nobody has found yet, incomplete repairs, a hazard that was not controlled, or lead stored in the body moving back into the blood. A level that will not come down is a signal to look again, not a reason to give up.

Adults and pregnancy

For adults, most elevated blood lead comes from work, according to NIEHS, in jobs such as construction, mining, welding and battery manufacturing. NIOSH, the CDC’s worker-safety institute, asks people who work with lead to tell their doctor, and describes steps at work, such as changing clothes and showering before going home, that protect both the worker and the family. ATSDR says professional judgment should guide any decision to chelate an adult.

Lead stored in the bones can move into the blood during pregnancy and reach the baby, the CDC says. If you are pregnant or breastfeeding and think you may have been exposed, talk to your health care provider. Do not start or stop anything on your own.

Why there is no home treatment

The CDC says the effects of lead poisoning can be permanent and disabling, and most children with lead in their blood have no obvious symptoms (see lead poisoning symptoms). Treatment cannot undo damage that has already happened, which is why the official focus is on stopping exposure early, supporting the child’s development and checking that levels fall. All of that runs through a doctor and the health department. What you can do at home is the prevention side: wet-clean dust, wash hands and toys, keep children away from peeling paint, use cold tap water for drinking and cooking, and test your home. Our guide to lead and children has the full CDC and EPA list.

Frequently asked questions

Can lead poisoning be cured?

Blood lead levels can come down once the source is removed, and doctors can treat very high levels. But the CDC says some effects of lead can be permanent, so the goal is to stop exposure as early as possible. Ask your doctor what to expect for your situation.

How do you treat lead poisoning at home?

You don’t. There is no home treatment. At home, you can help by following the health department’s advice to remove lead sources, keeping dust down and making sure follow-up blood tests happen. Any medical treatment comes from a doctor.

At what level is chelation used?

The CDC’s guidance for children places it at 45 µg/dL and above, decided with a medical toxicologist or experienced pediatrician. ATSDR calls 45 a guideline, not a fixed rule. The decision belongs to the medical team.

How long does it take for blood lead levels to go down?

Official sources do not give one timeline; it depends on the level, how long the exposure lasted and whether the source is gone. That is why the CDC sets follow-up tests from 2 weeks to 9 months apart depending on the result.

Does eating well lower lead levels?

The CDC recommends a diet high in iron and calcium for children with elevated blood lead, alongside removing the source. Diet supports the child; it does not remove lead or replace medical follow-up. Don’t give supplements unless your doctor says so.

Who pays for testing and follow-up?

The CDC says many private insurance policies cover blood lead testing, and Medicaid covers it for enrolled children. Ask your health department about home investigations and local programs, which vary by state.

Lead Poisoning Symptoms in Children and Adults

Lead poisoning symptoms are often vague or missing altogether, which is why so many cases are found only through a blood test. The CDC says most children with lead in their blood have no obvious immediate symptoms, and in adults the signs, such as stomach pain, headaches, tiredness or irritability, look like many other everyday illnesses.

A doctor talking with an adult patient in a clinic

In short: when symptoms do appear, official sources list stomach pain and cramping, constipation, nausea, headaches, tiredness, irritability, trouble sleeping, poor appetite and, in young children, learning, behavior and development problems. Very high levels can cause vomiting, a staggering walk, seizures or coma. A blood lead test is the only way to know. If someone has severe symptoms such as seizures or repeated vomiting, call 911. For other worries about exposure, call Poison Control at 1-800-222-1222 or talk to a doctor or your local health department.

This page explains what the CDC, its worker-safety institute NIOSH and the National Institutes of Health (through MedlinePlus) say about symptoms. It is not a diagnosis and not medical advice. Only a health care provider can tell you what a symptom means for you or your child.

Why lead poisoning is easy to miss

Lead builds up quietly. It is swallowed or breathed in as dust, chips, soil or contaminated food and water, and much of the harm happens before anyone notices anything. The CDC states plainly that most children with any lead in their blood have no obvious immediate symptoms, and that no safe blood lead level in children has been identified.

NIOSH makes the same point about adults: lead symptoms are similar to those of other illnesses and may develop slowly, so lead poisoning can be overlooked. A parent may put a toddler’s crankiness down to teething, and an adult may blame stress or poor sleep for headaches and fatigue. That is why doctors rely on a blood lead test, not on symptoms, to find exposure.

Signs of lead poisoning in children

The CDC describes the effects of lead in children mainly in terms of how it affects growing bodies and brains, rather than a short checklist of signs. According to the CDC, lead exposure in children can cause:

Damage to the brain and nervous system
Slowed growth and development
Learning and behavior problems
Hearing and speech problems

The CDC links these effects to lower IQ, a shorter attention span and doing less well in school, and notes evidence that childhood exposure can cause harm that lasts. Our page on the effects of lead poisoning explains the longer-term picture.

MedlinePlus, the National Library of Medicine’s consumer health site, adds symptoms that families sometimes notice day to day. For young children it lists the loss of developmental skills they had already learned, alongside irritability, aggressive behavior, low appetite and energy, trouble sleeping, constipation, and stomach pain and cramping. It also lists anemia (a low red blood cell count), which a doctor can find with a blood test.

None of these signs, alone or together, proves lead poisoning. They are common in children for many reasons. What they do mean is that if your child has them and also lives in or visits an older home, or may have been around one of the sources on our lead and children page, it is worth asking the pediatrician about a blood lead test.

Symptoms in adults

NIOSH, the CDC’s worker-safety institute, splits adult symptoms into two patterns.

Pattern	Symptoms NIOSH lists
High exposure over a short time	Metallic taste; stomach pain, nausea, vomiting; diarrhea or constipation; dehydration, headache, exhaustion, irritability, weakness; loss of appetite; memory loss; pain or tingling in the hands or feet
Exposure over a long time	Stomach pain, nausea and constipation; depression, irritability and mood or behavior changes; distraction and forgetfulness; higher blood pressure
Other effects NIOSH lists	Decreased lung function; bone or tooth loss; more infections in general; fertility problems in men and women

MedlinePlus also lists headaches, hearing loss, reduced sensations, difficulty getting pregnant and anemia among the symptoms of lead poisoning, and notes that stomach pain and cramping are usually the first sign of a high, toxic dose.

Adults most often meet lead at work or through hobbies: construction and renovation of older buildings, battery recycling, metal work, firing ranges, stained glass and similar crafts. NIOSH notes that workers can carry lead dust home on clothes, shoes and tools, exposing their families. If you work with lead, NIOSH advises telling your doctor and your family’s doctors.

Lead in pregnancy

The CDC says lead stored in a person’s bones from earlier exposure can be released into the blood during pregnancy, and that lead can pass to the baby. It links lead in the blood during pregnancy to a higher risk of miscarriage, of a baby being born too early or too small, and of harm to the baby’s brain, kidneys and nervous system. If you are pregnant or breastfeeding and think you may have been exposed, talk to your health care provider about testing.

Signs of very high exposure: when it is an emergency

MedlinePlus lists the signs of very high lead levels as vomiting, a staggering walk, muscle weakness, seizures and coma. These are rare, but they are emergencies.

Situation	What official sources say to do
Severe symptoms, such as seizures, repeated vomiting or loss of consciousness	Call 911 right away (MedlinePlus)
Other symptoms that might be from lead, or a child swallowed something that may contain lead	Call Poison Control at 1-800-222-1222, free and confidential, any time
You suspect ongoing low-level exposure (old paint, work dust, a recalled product)	Contact your health care provider or local health department; an emergency room visit is usually not needed unless the exposure was a high dose (MedlinePlus)

Poison Control is staffed by specialists who can tell you whether a situation needs urgent care. Keep the number in your phone.

The only way to know: a blood lead test

Because symptoms are unreliable, the CDC calls a blood lead test the best way to find out whether a child has lead poisoning, and the best way to assess a person’s exposure in general. Results are given in micrograms of lead per deciliter of blood (µg/dL). The CDC uses a blood lead reference value of 3.5 µg/dL to flag children whose levels are higher than most US children’s, and says any detectable lead means a child has been exposed.

The CDC says health care providers and most local health departments can do the test, many private insurance plans cover it, and Medicaid covers it for enrolled children. Children on Medicaid are required to be tested at 12 and 24 months, and between 24 and 72 months if they have never been tested. Our blood lead test guide explains finger-stick and venous tests, what results mean and what follow-up the CDC recommends.

Do not try to treat suspected lead poisoning at home or with supplements or products sold online. Decisions about care belong to a doctor, who can look at the test results, the source of exposure and the whole picture. Our lead poisoning treatment page explains what official guidance says doctors do.

When to ask a doctor about testing

The signs of lead poisoning are easy to miss, so risk matters more than symptoms. The CDC recommends that children at higher risk be tested. It names children who live in or regularly visit homes or buildings built before 1978, children in low-income households, children who are immigrants, refugees or recently adopted from other countries, and children who may be exposed through a household member’s job or hobby. Talk to a doctor if:

Your home was built before 1978 and has chipping or peeling paint, or has been renovated recently. See is lead paint dangerous?
Your home has a lead service line or you are not sure. See lead pipes.
Someone in the household works with lead or has a lead-related hobby.
Your child used a recalled product, such as the 2023 cinnamon applesauce pouches. See lead in cinnamon and spices.
You use imported spices, candies, traditional remedies, cosmetics or glazed pottery that could contain lead. See lead in pottery and dishes.
Your child has any of the symptoms above and you want to rule lead out.

Finding and removing the source

A blood test tells you whether someone has been exposed; it does not tell you where the lead came from. When a child’s level is at or above the reference value, the CDC says health departments may help find the source, and doctors may recommend removing lead hazards from the home, a diet rich in iron and calcium, early educational services and repeat testing.

For the home itself, the first steps are usually checking paint, dust, water and soil. Our guides on lead paint testing, lead water testing and dust and soil testing explain the options, and you can find a certified lead inspector or risk assessor for a full investigation. Where lead comes from and how to keep it out of your home is covered in lead poisoning causes and prevention, and more on health is on our lead poisoning hub.

Frequently asked questions

What are the first signs of lead poisoning?

Often there are none. The CDC says most children with lead in their blood have no obvious immediate symptoms. MedlinePlus notes that stomach pain and cramping are usually the first sign of a high, toxic dose. Only a blood lead test can tell.

What are the symptoms of lead exposure in adults?

NIOSH lists stomach pain, nausea, constipation, headaches, tiredness, irritability, mood changes, forgetfulness, higher blood pressure, tingling in the hands or feet and fertility problems, among others. Because they resemble other illnesses, tell your doctor if you may have been exposed.

Can lead poisoning symptoms go away?

Symptoms can come and go, which is one reason they are unreliable. The CDC says even low levels can affect children and that some effects can last. Ask a doctor about testing and follow-up rather than waiting to see whether symptoms fade.

How fast do symptoms appear?

It depends on how much lead and over how long. NIOSH separates short, high exposures, which can cause symptoms such as stomach pain and vomiting, from long, low exposures, which build up slowly. Many children with lead in their blood show nothing at all.

Who should I call if I think my child swallowed something with lead?

Call Poison Control at 1-800-222-1222. If your child has severe symptoms such as a seizure, trouble breathing or repeated vomiting, call 911.

Is there a home test for lead poisoning?

Lead in a person is measured with a blood test ordered by a health care provider or local health department. Home swab kits are made for surfaces like paint, not for people. Ask your doctor or health department about blood testing.
