I've been referred to gastroenterology due to a few bouts of rectal bleeding and high inflammation in my stools, with suspected IBD. I'm expecting that they will say I need a colonoscopy, but I'm really worried about the prep as when I have had diarrhoea in the past I have fainted (I think it's a vasovagal reaction to too much 'activity' happening in my digestive system). I'm really worried about the colonoscopy prep, and worried that I'll get the stomach cramps, cold sweat and sense of doom I have before I faint. It's the worst feeling in the world.
I'm just wondering if there are any doctors on here who may be able to advise? I'll bring it up with the gastroenterologist but I'm expecting them to say there's nothing they can do and I'll just have to get on with it (which I will if I'm told to do so), or whether there's anything they can do to mitigate it or do instead of the colonscopy prep? I'd happily fast for a week if it meant avoiding that feeling :(
