An 81-year-old man felt breathless and dizzy with cold hands and feet for the last 6 months. He had been on low dose aspirin since a cardiac bypass graft 12 years before and had been on dabigatran anticoagulant for atrial fibrillation. He reported passing black bowel motions suggesting blood loss from the upper gastrointestinal tract. Iron deficiency was confirmed, and an endoscopy was performed which showed gastritis. He received an iron infusion, the dabigatran was interrupted for a few days, aspirin was stopped and he was started on medication to heal his stomach. His symptoms improved after 5 weeks.
