The time to eat after gastric cancer resection is usually after 1 week, and in rare cases, it may be after 10 days. Generally, after 1 week of exhaustion, we should try to let the patient to inject sugar saline into the gastric tube first, and if the patient is not uncomfortable after injecting, enteral nutrition can be given first. If there is no discomfort after the injection, you can start to let the patient eat after the gastric tube is removed. The order of eating is usually from liquid food to semi-liquid food and then to normal diet. The regular liquid diet is millet rice, thin soup, or rice rice, or various soups such as chicken soup and pork ribs soup. If the patient has no problem after eating liquid food, the next step is to gradually return to semi-liquid food, which can add minced meat, millet and chopped vegetables, and then gradually transition to a normal diet.
