Preoperative fasting is the practice of a surgical patient abstaining from eating or drinking for a period of time before an operation. It is intended to reduce the amount of contents in the stomach, preventing them from entering the windpipe and lungs should the patient vomit or regurgitate while under general anesthesia.
