Gastroscopic polypectomy requires about three days in the hospital, about one week of rest and recuperation, and about one month of recuperation at home after discharge from the hospital. For two days after the operation, there may be vomiting, bloating and other discomforts due to anesthesia and the presence of gas in the stomach, and hospitalization is required for observation and therapeutic recuperation. In case of larger polyps, intravenous fluids are needed, as well as work to stop bleeding, which needs to be done in the hospital for about three days. Patients should note that during the postoperative hospitalization period, they should first eat liquid food, such as vegetable soup, noodle soup, etc., and then slowly transition to semi-liquid according to the body’s recovery, and finally to a normal diet, paying attention to the combination of meat and vegetables, and choosing warm, soft, fine, easy-to-digest food, to prevent the stomach because of the action of the food, and the discomfort that occurs in the postoperative period. During the hospitalization period, you should also keep your mood happy, and pay attention to observe the stool condition at any time, as well as whether there is any discomfort in the stomach.
