Iron deficiency, by far the most common cause of microcytic anemia, may be traced to abnormal bleeding, rapid growth, or rarely, inadequate diet. A search for the source of abnormal bleeding is particularly important because it may lead to detection of an ulcer or cancer. Orally administered iron supplements usually are effective; parenteral therapy is rarely needed.
缺铁是小细胞性贫血最常见的病因，可能源于异常出血、生长迅速，或极少情况下的饮食不足。寻找异常出血的源头尤为重要，因为这可能会发现溃疡或癌症。口服铁补充剂通常有效；很少需要肠外治疗。
