Patients with gastrointestinal bleeding can eat in about 5-6 days if their condition recovers smoothly. Gastrointestinal bleeding is a common disease, such as ulcer disease, gastric cancer, cirrhosis of the liver and liver cancer, which can cause gastrointestinal bleeding. Patients suffering from GI bleeding need to fast if eating during the bleeding activity will cause excessive secretion of gastric acid, which will cause the bleeding symptoms to worsen. After gastrointestinal bleeding, the patient will be given symptomatic treatment such as hemostasis and blood transfusion, and then the blood pressure will return to normal and there will be no more blood vomiting or blood in the stool until there is light yellow soft stool, at which time the patient can eat. Because of the fear that the rice porridge contains coarse and dry rice grains, which may cut or stimulate the newly healed wound and cause bleeding again, a small amount of rice soup can be given. A small amount of alkaline rice soup can be put in the rice soup to avoid stomach discomfort.
