A 70 year old male presented with melena for 2 months, multiple blood transfusions and an average hemoglobin of 4-5 gm/dl. UGI endoscopy revealed Ancylostoma duodenale worm infestation causing GI bleed, same features in capsule endoscopy. Patient improved with deworming.
Ancylostoma duodenale, a hookworm, attaches to the small intestinal mucosa and feeds on blood, causing chronic gastrointestinal bleeding. Repeated mucosal injury leads to occult or overt GI bleed, iron deficiency anemia, fatigue, and weakness. Severe infestations may result in significant morbidity, particularly in malnourished or immunocompromised patients.
