Minimally invasive surgery for gallstones needs to be performed under general anesthesia. Do not eat for 6 hours after general anesthesia because the anesthetic will have a certain reaction on the gastrointestinal tract, which may lead to nausea and vomiting after eating. In addition, anesthesia inhibits the function of the gastrointestinal tract, which may not be fully recovered within 6 hours. 6 hours later, you can eat thin rice first, and if there is no vomiting, abdominal pain and other symptoms occur, you can eat some soft rice after the 2nd day, and resume normal diet after 3 days, but still pay attention to lightness and avoid intake of meat and greasy food. Within 1-2 months after the operation, when the body slowly compensates, it can return to normal diet.
