Iron deficiency complicating celiac sprue is usually attributed to the malabsorption of dietary iron or the loss of iron from the intestinal mucosa. There has been little investigation of the role of intestinal loss of blood in patients with this condition. The purpose of this study was to determine the prevalence of occult gastrointestinal bleeding in patients with celiac sprue. ⋯ Occult gastrointestinal bleeding can be detected in about half of patients with celiac sprue and should be added to the list of factors that can contribute to iron deficiency in patients with this disorder.
