Lead poisoning happens when our body gets too much lead in it. Lead is a kind of metal that is very toxic, which means it is harmful to us if we have too much of it.
Lead can be found in different things, like old paint, soil, and even some toys. Sometimes, we can accidentally eat or breathe in lead without even realizing it. This is not good because lead can damage our brain, bones, and other parts of our body.
When we have lead poisoning, we can feel sick and have stomach pain, headaches or even get really tired. Doctors can test us to see if we have too much lead in our body and if we do, they may give us medicine or tell us to avoid things with lead so we can get better.
