Symptoms and Problems

Most children with lead poisoning show no symptoms. A parent may not realize their child has a lead issue until they have the child tested. Fortunately, prompt attention can limit the effects of the lead exposure. Symptoms that may be seen in children with lead poisoning but are commonly mistaken for other illnesses include:

  • Difficulty sleeping
  • Poor appetite
  • Weight loss
  • Stomach aches
  • Vomiting
  • Constipation
  • Joint Pain
  • Headaches
  • Concentration Difficulty
  • Restlessness
  • Irritability
  • Weakness
  • Tiredness
  • Diarrhea
  • Blindness
  • Convulsions
  • Fainting
  • Dizziness
  • Staggering gait


Low lead levels in children may cause problems with the nervous system and brain. Problems that may occur include interfering with growth, harming hearing, lowering IQ levels, causing behavioral issues and making learning more difficult. In addition, the child may become anemic. High levels of lead poisoning may result in convulsions, kidney failure, a coma and even death.
