In the developing world, parasitic worms, malaria, and HIV/AIDS increase the risk of iron deficiency anemia. Poor absorption of iron from food may occur as a result of an intestinal disorder such as inflammatory bowel disease or celiac disease, or surgery such as a gastric bypass. Sources of blood loss can include heavy periods, childbirth, uterine fibroids, stomach ulcers, colon cancer, and urinary tract bleeding. Iron-deficiency anemia is caused by blood loss, insufficient dietary intake, or poor absorption of iron from food. There may be additional symptoms depending on the underlying cause. Children with iron deficiency anemia may have problems with growth and development.

Anemia is typically significant before a person becomes noticeably pale. Anemia that comes on quickly often has more severe symptoms, including confusion, feeling like one is going to pass out or increased thirst. When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. Iron-deficiency anemia is anemia caused by a lack of iron.
