The Natural History of Iron Deficiency Anemia

摘要

Background: Current evidence suggests that adult men and nonmenstruating women with iron deficiency anemia (IDA) should undergo gastrointestinal (GI) evaluation to detect a potential bleeding lesion. We hypothesized that after endoscopic evaluation and treatment, IDA would be expected to resolve. Thus, we aimed to understand the natural history of IDA, in particular long-term outcomes.
