Patients with gastric ulcer bleeding should undergo emergency gastroscopy within 24-48 hours after bleeding to perform differential diagnosis, confirm the bleeding status, and conduct endoscopic treatment. The first choice of medication is drugs that suppress gastric acid secretion, commonly using PPI preparations or H2 receptor antagonists. However, PPI preparations and intravenous administration should be preferred in cases of major bleeding. If bleeding persists or recurs after pharmacological treatment, endoscopic treatment can be performed, including spraying hemostatic drugs, injecting sclerosing agents, and using hemostatic clips. If endoscopic treatment is unsuccessful, vascular interventional embolization or gastroduodenal artery treatment can be pursued. In cases where the patient repeatedly bleeds and both medical and endoscopic treatments are ineffective, surgical intervention may be considered.
