Duodenal bulb ulcers often manifest as hunger-like pain in the upper abdomen, which relieves after eating, accompanied by nocturnal pain. Symptoms also include acid reflux, heartburn, nausea, etc. If there is bleeding, symptoms may include black stools and vomiting blood. Treatment depends on whether there is a Helicobacter pylori infection. If there is a Helicobacter pylori infection, antibacterial treatment is required, commonly using a triple or quadruple antibiotic therapy for two weeks. If there is no Helicobacter pylori infection, symptomatic treatment is sufficient, generally using proton pump inhibitors and gastroprotective medications such as bismuth agents. Additionally, it is important to develop good dietary and lifestyle habits to prevent recurrence.
