Unmasking the Hidden Culprit: Capsule Endoscopy Reveals Diffuse Hookworm Infestation as a Cause of Obscure Gastrointestinal Bleeding and Refractory Anemia—A Case Report

2026Open accessUniversity of Khartoum

Abstract

A 70-year-old woman with transfusion-dependent anemia and ongoing gastrointestinal bleeding had inconclusive findings on imaging, upper endoscopy, and colonoscopy. Capsule endoscopy revealed the diagnosis: diffuse hookworm infestation causing active bleeding throughout the small bowel and colon. Targeted anthelmintic therapy resolved her anemia completely.
