Do not eat anything for eight hours before surgery. This is a common rule: if your surgery is in the morning do not eat after midnight the night before surgery. This rule applies even if you have a local anesthetic. If you eat or drink even small amounts I may cancel your surgery. This is for your own safety. If you have food in your stomach and you vomit, some of that food may enter your lungs. This is a very serious complication. So no matter how tempted you are, do not eat or drink before surgery. Do not chew gum the morning of surgery. It is a good idea to eat a nourishing diet for a week or two before surgery. Consider increasing your vitamin C intake. Do not go on a strict diet in the weeks before your operation.
