Colonoscopy is necessary for initial diagnosis, and for colorectal cancer screening after 10-years of diagnosis.
Beyond that, endoscopy (a colonoscopy or flex-sigmoidoscopy) can be used for diagnostic purposes during flare onset or when treatments fail (to assess how far and how severe the inflammation goes, and treat it with appropriate meds). Is endoscopy always necessary in the proceeding? Sometimes fecal Calprotectin (FCP) stool test or C-Reactive Protein (CRP) blood test is enough to get the inflammation level. A flex-sig doesn't require drinking a prep at all, just two fleet enemas are taken and it can be easier to do. It cannot hurt to ask, would if a FCP, CRP, or flex-sig would be enough.
