- Duodenal ulcer
- An ulcer (a hole in the lining) of the duodenum (the first portion of the small intestine). Ulcers can affect the stomach, duodenum, or esophagus.

Diagnosis is made with barium x-ray or endoscopy. Complications of ulcers include bleeding, perforation, and blockage of the stomach (gastric obstruction). Treatment involves antibiotics to eradicate H. pyloridus, eliminating risk factors, and preventing complications.
