iron deficiency anemia

For a discussion of iron deficiency more broadly, see the Wikipedia article iron deficiency. Iron deficiency anemia is the most common type of anemia, and the most common cause of microcytic anemia. Iron deficiency anemia occurs when the dietary intake or absorption of iron is insufficient, and hemoglobin, which contains iron, cannot be formed. In the United States, 20% of all women of childbearing age have iron deficiency anemia, compared with only 2% of adult men. The principal cause of iron deficiency anemia in premenopausal women is blood lost during menses.
