How long you can eat after gastric polyp surgery depends on the patient’s surgical procedure and the patient’s recovery. First, if the patient undergoes gastroscopic excision of gastric polyps, and the polyps are small. The wound stops bleeding soon after surgery. In this case, the patient can have a liquid diet 2-3 days after surgery. About 1 week after surgery, the patient can transition to a normal diet. Second, if the patient has a large gastric polyp that cannot be removed endoscopically. Then it is necessary to perform open or laparoscopic surgery to remove gastric polyps. In this case, due to the large abdominal trauma, the patient’s gastrointestinal function recovers more slowly after surgery. It is often possible to try warm water only after anal discharge and defecation 5 days after surgery. It takes about 1 week after surgery for the intestinal function to slowly recover before a liquid diet is available, and patients can eat and drink completely normally in about 14 days after surgery.
