The severity of gastric bleeding is judged by the amount of bleeding, the speed of bleeding, and the location of bleeding. If the gastric bleeding is fast and large, the condition is serious; if the bleeding is slow and small, it is not serious and relatively easy to treat. Patients with gastric ulcer often have regular postprandial epigastric pain. If only a small amount of blood is oozing, it is not serious and oral medication is usually sufficient; if the bleeding is heavy, gastroscopic treatment may be required. Acute erosive hemorrhagic gastritis is not serious when bleeding is small, and patients may have no symptoms and only be detected during gastroscopy, and regular treatment is sufficient; however, if there is a large amount of blood vomiting and blood in stool, it needs to be taken seriously and treated in a timely manner. In addition, stomach bleeding in patients with gastric cancer is relatively serious; stomach bleeding in patients with cirrhosis usually causes vomiting blood or blood in stool, and generally the bleeding is large, fast and more critical, which needs to be treated as soon as possible. As for the diet of gastric bleeding patients, it is recommended to eat breakfast, lunch and dinner on time, try to eat softer food, avoid spicy and stimulating food, and consume moderate amount of high-protein food such as fish, eggs and beef to supplement nutrition.
