Fish soup can be consumed 1~3 days after gastric polyp removal, the exact time depends on the way of surgery as per doctor’s advice. If gastroscopic polypectomy is chosen, it is a minimally invasive surgery. Generally, it is necessary to fast for 1 day after the operation, and then you can eat fluids on the 2nd day, such as fish soup, rice soup, etc. If there is no discomfort, you can resume a semi-liquid diet on the 3rd day, such as rice gruel, noodles and egg custard. If the diameter of the polyp is larger than 2 cm and endoscopic submucosal dissection is performed, fasting may be required for 2~3 days, and if no other discomfort occurs, fluid fish soup, rice soup, etc. can be eaten gradually. The specific feeding time after gastric polypectomy is recommended to follow the doctor’s instructions, the diet should be soft, easy to digest food, eat small amounts of food, should not eat too full.
