Lead poisoning
What is Lead poisoning?
Lead poisoning happens when lead builds up in your body over months or years. Lead is a toxic heavy metal found in older paint, contaminated soil, certain pipes, and some products. Even small amounts can cause serious health problems.
Your body has no use for lead. When it enters through breathing, swallowing, or skin contact, it accumulates in your blood, bones, and organs. Lead interferes with how your cells work and damages your nervous system, kidneys, and other vital systems.
Children under age 6 are most vulnerable because their bodies absorb lead more easily. Their brains and nervous systems are still developing. Adults who work with lead or live in older homes also face higher risk. The good news is that lead poisoning is preventable when you know the sources.
Symptoms
- Abdominal pain and cramping
- Constipation or digestive problems
- Fatigue and weakness
- Headaches
- Irritability and mood changes
- Loss of appetite
- Memory loss and difficulty concentrating
- Pain or tingling in hands and feet
- Muscle and joint pain
- High blood pressure in adults
Many people with early lead exposure have no obvious symptoms. This makes testing important if you have known risk factors. Children may show developmental delays, learning difficulties, or behavioral problems before other signs appear.

Causes and risk factors
Lead poisoning occurs when you are exposed to lead through your environment. The most common source is paint in homes built before 1978, when lead paint was banned. Dust from peeling or chipped paint settles on surfaces and hands. Soil near older homes or busy roads can also contain high lead levels from old gasoline and paint.
Other sources include contaminated drinking water from lead pipes or fixtures, certain imported ceramics and cookware, some cosmetics and traditional remedies, and occupational exposure in construction, battery manufacturing, or auto repair. Children who put hands and objects in their mouths face higher risk. Adults who work with lead or renovate old homes without proper safety measures are also vulnerable.
How it's diagnosed
Lead poisoning is diagnosed through specialized testing that measures lead levels in your blood or urine. A simple blood test is the most common method for detecting lead exposure. Urine testing can also show recent exposure and help monitor lead levels over time.
If you suspect lead exposure, talk to your doctor about testing. While Rite Aid does not currently offer lead testing, our medical team can help you understand your symptoms and connect you with appropriate testing resources. Early detection allows for faster intervention and better outcomes.
Treatment options
- Remove the source of lead exposure immediately by identifying and eliminating contaminated paint, soil, water, or products
- Clean your home thoroughly using wet mops and cloths to capture lead dust without spreading it
- Wash hands frequently, especially before eating and after being outdoors
- Eat foods rich in calcium, iron, and vitamin C to help reduce lead absorption
- Chelation therapy for severe cases, where medication binds to lead so your body can remove it
- Regular monitoring of lead levels to track progress and ensure levels are dropping
- Nutritional support to address deficiencies and support detoxification
Most cases of lead poisoning improve once exposure stops and the body gradually eliminates stored lead. Children may need educational support if lead affected their development. Always work with a healthcare provider who can monitor your progress and recommend the right treatment plan for your situation.
Frequently asked questions
Early signs often include fatigue, headaches, and abdominal pain. Many people have no symptoms at first, which is why testing is important if you have risk factors. Children may show irritability, loss of appetite, or developmental delays before other symptoms appear.
Lead enters your body when you breathe dust or fumes containing lead, swallow contaminated food or water, or absorb it through skin contact. The most common route is swallowing lead dust from old paint. Children often get exposed by putting contaminated hands or objects in their mouths.
Your body can eliminate lead over time once exposure stops. Treatment focuses on removing the source and supporting your body's natural detoxification. Severe cases may need chelation therapy to speed up lead removal. Some effects, especially in children, may be permanent if exposure was severe or prolonged.
A blood test is the standard method for detecting lead poisoning. The test measures the amount of lead in your bloodstream. Urine testing can also detect recent exposure and monitor treatment progress. Your doctor can order these specialized tests through clinical laboratories.
Children under 6 years old face the highest risk because their bodies absorb more lead and their brains are developing. People living in homes built before 1978 are at risk from old paint. Workers in construction, battery manufacturing, and auto repair also have higher exposure risk.
Foods high in calcium, iron, and vitamin C help your body absorb less lead. Dairy products, leafy greens, lean meats, and citrus fruits are good choices. Eating regular, nutritious meals also helps because lead is absorbed more easily on an empty stomach.
Lead can remain in your bones for decades after exposure ends. Blood lead levels typically drop within weeks to months once exposure stops. The timeline depends on how much lead you absorbed and how long exposure lasted. Children eliminate lead faster than adults.
Yes, adults can develop lead poisoning, though it typically takes higher exposure levels than in children. Adults most often get exposed at work or during home renovations. Symptoms include fatigue, headaches, high blood pressure, joint pain, and memory problems.
Lead poisoning is highly preventable with the right precautions. Keep your home clean and dust-free if it was built before 1978. Use cold water for drinking and cooking, and let taps run briefly before use. Wash hands frequently and avoid bringing work clothes worn around lead into your home.
Chelation therapy uses medication that binds to lead in your bloodstream so your body can eliminate it through urine. Doctors reserve this treatment for severe cases with very high lead levels. The medication is given by mouth or through an IV depending on the severity and the patient's age.
