Lead poisoning occurs when lead builds up in the body over time, causing serious health problems. It can affect many body systems, especially in young children, including the brain, nervous system, kidneys, and heart. There is no cure—only management. Preventing exposure is critical. Medical treatment, like chelation therapy, may be necessary at very high blood lead levels.
Even small amounts of lead can cause permanent damage. It affects brain development, behavior, learning, speech, hearing, and overall growth. It may lead to decreased academic performance, attention disorders, and anxiety. There is no safe blood lead level in children.
Contact your health care provider to schedule a blood lead test. In New York, testing is required by law at ages 1 and 2, and may be needed at other times based on risk factors. If exposure is confirmed, your provider can guide the next steps, including developmental support and environmental investigation.
If your child has elevated blood lead levels, your health care provider may recommend:
Developmental evaluations
Nutritional guidance (especially iron and calcium)
Referrals to specialists or early intervention programs
Stopping exposure and ongoing monitoring are essential to minimize long-term impacts.
