To undergo a surgery operation that requires anesthesia, especially if it is general anesthesia, it is advice not to eat or drink several hours before the intervention.
This is treating to prevent some complications by having an empty stomach, digestive tract and bladder. For example, having an empty stomach reduces the chances of the patient vomiting during the operation, a side effect that anesthesia may provoke.
The time before the patient should not eat or drink depends on the operation, although the most common is not to eat or drink between 8 and 12 hours before the operation. It is also generally recommended that the last meal be light and do not drink alcohol or smoke during this time.
