Low ferritin (iron deficiency) increases lead absorption in children. Iron and lead use the same intestinal transport pathways, so when iron stores are low, the body may absorb more lead from water, food, or airborne particles — even when a child lives in a newer home not associated with lead-based paint (post-1978 housing).
Pediatric treatment usually includes iron supplementation or vitamins, and physicians often monitor blood lead levels over many months. As iron stores improve, lead levels may decline over time.
