nothing! at least not after midnight the night before. and don’t drink anything either. a few bites of food or sips of coffee before your colonoscopy may seem like no big deal. but you won’t be fooling your gastroenterologist. a little food goes a long way toward obscuring the view of your colon. that makes it harder to identify any polyps or potential tumors during a colonoscopy. it might seem almost unbearable to go hungry or face a medical procedure caffeine-free. but think how much more uncomfortable it will be to undergo a repeat colonoscopy because of your “poor prep. ” peanut butter
what am i allowed to eat before having a colonoscopy?
