Duodenal ulcers generally do not cause diarrhea. Instead, they typically present with upper abdominal pain—especially pronounced at night. Diarrhea is usually not associated with duodenal ulcers. It may instead result from bacterial or viral infections within the body, or from unhealthy dietary habits.
