Why can't I eat or drink before surgery?
The likelihood that a patient will vomit during the anesthetic is increased with a short time interval between eating or drinking and the surgery. The most likely times for someone to vomit are going to sleep and waking up. Your risk of having a complication is increased if these events occur. The exception to this is emergency surgery, and special precautions will be taken to minimize the risk.
