Iron deficiency anemia may result from:
❑ inadequate dietary intake of iron (less than 1 to 2 mg/day), such as in prolonged unsupplemented breast-feeding or bottle-feeding of infants or during periods of stress such as rapid growth in children and adolescents
❑ iron malabsorption, such as in chronic diarrhea, partial or total gastrectomy, chronic diverticulosis, and malabsorption syndromes, such as celiac disease and pernicious anemia
❑ blood loss secondary to drug-induced GI bleeding (from anticoagulants, aspirin, and steroids) or due to heavy menses, hemorrhage from trauma, GI ulcers, esophageal varices, or cancer
❑ pregnancy, which diverts maternal iron to the fetus for erythropoiesis
❑ intravascular hemolysis-induced hemoglobinuria or paroxysmal nocturnal hemoglobinuria
❑ mechanical erythrocyte trauma caused by a prosthetic heart valve or vena cava filters.
A common disease worldwide, iron deficiency anemia affects 10% to 30% of the adult population of the United States. It occurs most commonly in premenopausal women, infants (particularly premature or low-birth-weight neonates), children, and adolescents (especially girls). Persons who are at increased risk for iron deficiency include those of low socioeconomic status who don’t get a well-balanced diet that includes iron-rich foods.

Iron deficiency anemia may result from:
❑ inadequate dietary intake of iron (less than 2 mg/day) — for example, during prolonged, unsupplemented periods of breast- or bottle-feeding (not eating solid foods after age 6 months) and during periods of stress, such as rapid growth in children and adolescents
❑ iron malabsorption, as in chronic diarrhea, partial or total gastrectomy, and malabsorption syndromes such as celiac disease
❑ blood loss secondary to drug-induced GI bleeding (from anticoagulants, aspirin, or steroids) or due to heavy menses, hemorrhage from trauma, a GI ulcer, cancer, or bleeding varices
❑ pregnancy, which diverts maternal iron to the fetus for erythropoiesis
❑ intravascular hemolysis-induced hemoglobinuria or paroxysmal nocturnal hemoglobinuria
❑ mechanical erythrocyte trauma caused by a prosthetic heart valve or vena cava filters.
Iron deficiency anemia is most common in premenopausal women, infants (particularly premature and low-birth-weight infants), children, and adolescents (especially girls).
