Are there any symptoms of lead exposure that parents should look for?

Answer: Most lead exposure is asymptomatic, which means there are no symptoms at all.

Lead can be detected at levels that are hazardous for brain development, but are without overt symptoms.

At higher levels of lead exposure, children can develop stomach aches or other gastrointestinal symptoms, feelings of lethargy, head aches or anemia. But those higher lead levels are pretty unusual.
