Gastric bleeding fasting time depends on the patient’s condition, if the amount of bleeding is relatively small, generally fasting for about three days can be. If the amount of bleeding is relatively large also need hospitalization, if necessary intravenous infusion, hemostatic drugs, and in serious cases also need blood transfusion, so the fasting time is longer. The main thing is to observe whether the patient’s bleeding stops, for example, the symptoms are relieved, the stool turns yellow, and the red blood cell and hemoglobin values are found to be stable during the routine blood test, that is, there is no more gastric bleeding, and only then can the patient be considered to eat a liquid or semi-liquid diet. If the bleeding is caused by gastritis or gastric ulcer, usually the bleeding can be stopped after conservative treatment for a period of time, but if the bleeding is caused by gastric cancer, surgery should be considered after the cause is clear.
