<unk>  occurs when body iron stores are inadequate to meet normal metabolic demands of the body. It is the most common cause of microcytic anemia.<unk>  occurs in the setting of blood loss, insufficient dietary intake or poor oral absorption of iron from food. Symptoms of<unk>  including fatigue, weakness, shortness of breath, lightheadedness, and pallor. Twenty percent of all women of childbearing age have<unk> , compared with only 2% of adult men.

In post menopausal women and men, the main cause of iron<unk>  are digestive tract diseases.<unk>  is the final stage of iron<unk> . When the body has sufficient iron to meet its needs (functional iron), the remainder is stored for later use in the bone marrow, liver, and spleen. Iron<unk>  ranges from iron depletion, which yields little physiological damage, to<unk> , which can affect the function of numerous organ systems. Iron depletion causes the amount of stored iron to be reduced, but has no effect on the functional iron. However, a person with no stored iron has no reserves to use if the body requires more iron. In essence, the amount of iron absorbed by the body is not adequate for growth and development or to replace the amount lost.
