(Harper)The concentration of iron in the body "is regulated carefully by absorptive cells in the small intestine, which alter iron absorption to match body losses of iron" (Harper). These cells are shown in the picture below:
These cells have a 2-3 day life cycle, and are sloughed off into the intestinal lumen when they die (Harper).
Iron is absorbed through three different pathways, heme, ferrous, and ferric acid, that are shown in the picture below:
(Harper).Dietary iron contains both heme and nonheme elements, which are absorbed "noncompetitively into duodenal and jejunal mucosal cells" (Harper). However, many different factors can cause these pathways to malfunction, as shown in the picture below:
(Harper)."Either diminished absorbable dietary iron or excessive loss of body iron can cause iron deficiency" (Harper). Diminished absorbable iron is usually a result of a lack of iron consumption, and hemorrhages are the main cause for a loss of body iron. When a hemorrhage occurs, "the bone marrow is stimulated to increase production of hemoglobin, thereby depleting iron in body stores. Once they are depleted, hemoglobin synthesis is impaired and microcytic hypochromic erythrocytes are produced" (Harper).
Some other blood loss diseases include hemosiderinuria, hemoglobinuria, and pulmonary hemosiderosis. These are blood loss through the urine, through heart surgery, and through renal disorders (Harper).
Iron deficiency anemia resulting from poor absorption can be caused by either a genetic disorder, having a major surgery performed on the small intestine, or having a DI tract disease (like celiac disease) which may cause absorption problems (Harper).
