Diet after abdominal surgery is a common problem that bothers patients and families. There are many kinds of abdominal surgeries, such as appendicitis, intestinal adhesion release, bowel resection anastomosis, small bowel surgery, and colorectal surgery. The size of the surgery varies and each patient is different, so the postoperative diet needs to be individualized. A reasonable diet helps patients recover smoothly. An unreasonable diet not only prolongs the recovery time, but can even cause serious postoperative complications, such as intestinal obstruction and intestinal fistula. I. Doctors will check the room every day, so you can ask them about diet during the checkup. The doctors in our department check in every day to see the patients they are assigned to, 365 days a year, usually between 8:00-9:00. If you are not sure about something, we suggest you to ask during the check-in, because doctors are very busy with patients, discharges, consultations and surgeries every day, and cannot guarantee that we are available at other times. If a patient has a temporary special problem, you can consult with the doctor or nurse on duty, who will be in the department 24 hours a day.
