You may be told not to eat or drink anything after midnight before your procedure. This will reduce the risk of "aspiration", where food or liquid in your stomach gets into your lungs while you are under anesthesia. We want to minimize this risk.
Talk to your anesthesia providers for guidance. You may be told to take your regular medications with a sip of water on the day of your procedure. It is extremely important that you follow the preoperative instructions you are given.
