For the last eight hours prior to your surgery, refrain from eating or drinking anything. Sips of water and chewing gum are examples of this. While you are under general anesthesia, it is possible that you might regurgitate if your stomach is not completely empty. You might breathe in food or water if this takes place. In order to protect your safety, the surgery will need to be postponed if you consume food or liquids within eight hours of the procedure.
