Iron Pill Gastritis: An Under Diagnosed Condition With Potentially Serious Outcomes

Given the ubiquitous use of oral iron therapy, their side effects are often encountered and well recognized in clinical practice. However, iron pill gastritis remains an often under-reported and elusive diagnosis. An astute clinician should be aware of this condition in order to promptly discontinue oral iron and institute timely treatment. Here in, we present a case of a 46-year-old woman who presented to the gastroenterology clinic with vague epigastric pain and microcytic anemia. Esophagogastroduodenoscopy revealed multiple gastric erosions and non-bleeding gastric antral ulcer with biopsies showing excessive iron deposition suggestive of iron pill gastritis. We reviewed the clinical features, pathology, and treatment of iron pill gastritis along with the review of the literature.
