Resumen

Lead poisoning is a medical condition caused by accumulation of lead in the body. Lead is a toxin that can accumulate in the body and damage almost every organ and system. Early symptoms of lead poisoning include irritability, difficulty sleeping, and loss of appetite. As the level of lead in the blood increases, more serious symptoms develop, including abdominal pain, vomiting, seizures, and coma.
