The treatment of peptic ulcers mainly depends on their cause. It is generally believed that infection with Helicobacter pylori is most closely related to peptic ulcers. In such cases, the first step is to check for Helicobacter pylori infection. If there is an infection, antibacterial treatment is generally used, with the common regimen being quadruple therapy: a proton pump inhibitor plus two antibiotics and a bismuth agent. If there is no Helicobacter pylori infection, symptomatic treatment is generally sufficient. The preferred method is to use acid-suppressing and stomach-lining-protecting medications, combined with symptomatic treatment. At the same time, it is helpful to develop good dietary and living habits, opt for a light and easy-to-digest diet, and eat regularly in fixed amounts. Avoid overeating and excessive fatigue; abstain from smoking and alcohol, and maintaining a good mood all help. (Medication should be used under the guidance of a professional doctor.)
