Duodenal bulb ulcers are definitely treatable. Treatment is mainly through medication, with the specific approach depending on the presence of Helicobacter pylori infection. If there is no Helicobacter pylori infection, treatment primarily focuses on symptomatic relief using traditional medicines such as proton pump inhibitors, like omeprazole and lansoprazole. If Helicobacter pylori infection is present, antibacterial treatment is generally needed, using either triple or quadruple antibiotic therapy; triple therapy consists of a proton pump inhibitor plus two antibiotics, and adding bismuth forms quadruple therapy. One treatment cycle lasts two weeks, and after completing medication, Helicobacter pylori can be rechecked in one month. Additionally, it's important to maintain good dietary and living habits. If recurrent duodenal bulb ulcers cause bleeding at night, surgical treatment can typically be considered.
