Does lead poisoning go away?

Can your body get rid of lead?

As the body naturally gets rid of the lead, the level of lead in the blood falls. Kids with severe cases and extremely high lead levels in their blood will be hospitalized to get a medicine called a chelator. The chelator attaches to the lead and makes the lead weaker so the body can get rid of it naturally.
