What condition can arise from a deficiency in iron in children?

A deficiency in iron in children commonly leads to anemia, specifically iron-deficiency anemia. This occurs when there is insufficient iron in the body to produce adequate hemoglobin, the protein in red blood cells responsible for carrying oxygen. In children, this can manifest as fatigue, weakness, pale skin, and a decrease in cognitive and physical performance. Iron is crucial during periods of rapid growth, such as childhood, making it essential to monitor iron levels to prevent anemia, particularly in populations at higher risk or with inadequate dietary intake.
