There are two reasons why patients’ stomachs are bigger after laparoscopic surgery: 1. In the process of laparoscopy, carbon dioxide needs to be filled into the abdominal cavity to make the field wider, and the absorption of carbon dioxide takes some time, so the stomach will be a bit bigger before it is completely absorbed. 2. For this situation, the main thing is to be more active, to turn over more in bed, and to walk properly after being able to get out of bed, which can promote intestinal peristalsis. Do not eat anything before you have exhausted, otherwise it is easy to aggravate the situation of intestinal distension and intestinal obstruction.
