Answer D.
Iron, like other divalent cations, is absorbed proximally in the duodenum and upper jejunum. Because sprue is a proximal intestinal disorder, patients may malabsorb iron. There is also recent
evidence that patients with sprue may lose iron. The rare Crohn’s disease patient with proximal intestinal disease may malabsorb iron; more often these patients have colonic blood loss from inflammation. Patients with a Bilroth II gastrojejunostomy bypass the main intestinal absorptive surface for iron uptake. Chronic pancreatitis does not influence iron absorption.Category:
