Lead Poisoning Child



Lead is a toxic metal in the environment. In children, lead poisoning is a blood level of lead that is 20 mcg/dL or more. It can lead to brain damage.


Lead poisoning is caused by eating, drinking, or breathing in tiny pieces of lead. This can happen quickly or over a period of time.

The most common causes are exposure to:

  • Lead-based paint—used in homes built before 1978
  • Dust, soil, or fumes that contain lead
  • Drinking water from lead pipes or pipes with lead-based soldering
  • Foods in lead-soldered cans from outside the US

Risk Factors

This problem is more common in children under 5 years of age. Other things that may raise the risk are:

  • Eating non-food items
  • Living in a house or apartment built before 1978, especially before 1960
  • Drinking water from pipes built before 1986
  • Living with adults who are exposed to lead— from work or hobbies
  • Receiving blood transfusions from adults with high lead levels
  • Being born to a mother with high levels of lead
  • Having low levels of iron in the blood



Children with lead poisoning may not have symptoms. Those who do may have:

  • Problems with behavior, learning, and attention
  • Difficulty hearing
  • Slow growth
  • Tiredness or weakness
  • Headaches
  • Nausea and vomiting
  • Lack of hunger and weight loss
  • Belly pain
  • Problems sleeping
  • Irritability
  • Clumsiness
  • Seizures or coma


The doctor will ask about your child's symptoms and health history. A physical exam will be done. A blood test can diagnose lead poisoning. This test may also be done in young children as part of a routine appointment.



Treatment depends on the severity of lead poisoning. It may include:

  • Monitoring the lead levels of a child with mild to moderate poisoning
  • Using medicine to remove lead from the body of a child with severe poisoning

Sources of lead will need to be removed from the child's environment. Public health officials can help.


The risk of lead poisoning can be lowered by removing sources of lead from a child's environment.
