Good morning everyone. I was diagnosed with diverticulitis back in feb, took me a few months to finally schedule a colonoscopy due to no insurance. My question is... 2 days ago I picked up a really bad cold... congestion. ..cough..sinus issues with it too. I'm to start my preparation tomorrow, and the colonoscopy is set for Tuesday morning. Will they still be able to do the procedure? I know they put you out for it..so I'm just wondering if I should call them before starting the prep.
