Re: Gas and flatulence, celiac symptom?
Have NO fear of your Colonoscopy. I have had two,one on its own and one with the Endoscopy.
You will be sedated and will not know about it. I was worried myself the first time but after I was sedated I didn't know anything about it infact I thought I had had the best nights sleep ever. No after effects either except for a feeling of Gas/Wind and that went after a few hours and I had my dinner as usual.
I wish you well and do let us know how you get on,
