Iron deficiency anemia

Iron deficiency anemia refers to anemia caused by an imbalance between the body's demand for and supply of iron, leading to depletion of stored iron in the body, followed by iron deficiency within red blood cells. Iron deficiency anemia is the most common type of anemia. Increased iron requirements with insufficient iron intake, impaired iron absorption, and excessive iron loss can all cause iron deficiency anemia. Patients may have symptoms such as fatigue, easy tiredness, dizziness, growth retardation in children, intellectual disability, and susceptibility to infection, which should be actively prevented and treated.
