title: The stomach and iron deficiency anaemia: a forgotten link.
abstract: Iron deficiency anaemia is generally considered a sign of occult bleeding from the gastrointestinal tract, and standard care therefore includes evaluation of the gastrointestinal tract to rule out possible bleeding sites. However, it is often overlooked that iron deficiency anaemia may be the result of an imbalance between iron loss and iron intake, and may also be due to reduced absorption of iron from food, i.e., coeliac disease. The absorption of alimentary iron is not a simple process and the stomach plays a major role in this process of iron "digestion". This review presents evidence linking iron deficiency anaemia to gastric conditions that lead to reduced acid secretion, such as, for example, gastric surgery, atrophic body gastritis and Helicobacter pylori gastritis.
