Gastric ulcer bleeding is a relatively common complication. First, it is important to soothe the patient's emotions, encourage rest, reduce mental stress, and pay attention to significant bleeding, which can cause vomiting of blood. It is necessary to promptly clean the blood stains in the mouth to prevent aspiration, provide timely symptomatic treatment, and choose to use proton pump inhibitors combined with endoscopic hemostasis. Vascular intervention or surgery may be required when necessary. Dietary management should be strengthened, with regular meals, consumption of soft, easily digestible food, and avoidance of hard, cold foods. It is crucial to strictly abstain from smoking and alcohol, and to consume less strong tea, coffee, etc., while actively treating any complications. (Please use medications under the guidance of a doctor.)
