Anesthesia Recovery
If your surgery requires you to go under general anesthesia, you may not be allowed to eat solid foods for a few hours after surgery. When your body awakens after anesthesia, your digestive system also needs some time to adjust. Filling your belly with solid foods shortly after surgery may cause you to feel nauseous and might lead to vomiting. Your physician may allow you to have lemon-lime soda, juice or plain crackers, but you should not have anything else by mouth for at least a few hours after you awaken from anesthesia.
