Gastric ulcer bleeding is a relatively common complication. Treatment methods can be selected based on the endoscopic characteristics of the bleeding lesion. Active bleeding can be treated with acid-suppressing medications such as proton pump inhibitors, combined with endoscopic treatment, and if necessary, vascular interventional treatment or surgery. For those with blood clots, proton pump inhibitors can also be chosen, with endoscopic treatment if necessary. During endoscopy, fibrin glue can be sprayed on the surface of the ulcer, adrenaline can be injected at the bleeding site, and endoscopic hemostatic clip techniques can be used. During treatment, it’s important to adjust the diet. For those with significant bleeding, temporary parenteral nutrition should be chosen, and no food should be consumed to avoid further gastrointestinal irritation. (Please use medications under the guidance of a doctor.)
