The time to stop bleeding in patients with gastric hemorrhage should depend on the severity of the condition, which usually takes about 2 weeks to be cured, and may take 4 to 8 weeks in severe cases. Gastric bleeding is one of the common clinical symptoms in emergency department and gastroenterology, often caused by gastric ulcer, esophagogastric fundal varices, acute erosive hemorrhagic gastritis and gastric cancer. Mild cases may be asymptomatic or present with vomiting of blood, tarry black stools, bloody stools and so on. In severe cases, shock may occur due to rapid and excessive bleeding, which can be life-threatening if not treated in time. According to the etiology, gastric hemorrhage can be divided into non-variceal gastric hemorrhage and variceal gastric hemorrhage; according to the clinical manifestation, it can be divided into acute hemorrhage and chronic occult hemorrhage. Gastroscopy is the preferred examination method to diagnose the cause of gastric bleeding. Emergency gastroscopy within 24 to 48 hours after bleeding can directly observe the condition of the lesion, with or without active bleeding or assess the risk of rebleeding, clarify the cause of bleeding, and at the same time provide hemostatic treatment for the bleeding lesion. Patients with gastric bleeding are advised to seek prompt medical attention for a clear diagnosis and targeted treatment under a doctor’s guidance.
