In the early postoperative period, patients are typically given planned intravenous nutrition. The purpose of feeding patients in the early postoperative period is to help the gastrointestinal tract gradually adapt during the recovery period. Doctors recommend that patients eat foods that are easy to chew, light and low in salt. Smaller and more frequent meals are recommended, and each portion should not be too large. Oral solution with potassium is usually taken half an hour after a meal to avoid irritation of the gastrointestinal tract.
