The causes of iron deficiency include a diminished intake of iron in the diet, decreased gastrointestinal absorption, and excessive iron store loss due to bleeding. Diminished absorption usually is due to an insufficient intake of dietary iron in an absorbable form. Blood loss is the most common cause of excessive loss of body iron in developed countries, but it can also occur with hemoglobinuria from intravascular hemolysis. Malabsorption of iron is relatively uncommon in the absence of small bowel disease (eg, sprue, celiac disease, regional enteritis, Helicobacter pylori infection) or previous gastrointestinal surgery.
