Colon prep requires several days of low-fiber diet, causing constipation and possible painful diverticulitis flare-up. Last colonoscopy was 7 years ago, no polyps. Anxiety motivated me to ask for another one after 3 family members diagnosed with colon cancer. However, all were determined to be sporadic cancers, ie, not genetic. And colonoscopies are recommended every 10 years. I’m now re-thinking if I should proceed; I’ve read about the elevated risks of colonoscopy for those over 70 (the recommended cut-off for these screenings is age 75). I'm obese, have high blood pressure (well controlled) and pre-diabetes (controlled with diet). Sometimes my pulse dips to 40-42 momentarily, but heart monitoring two years ago indicated nothing serious. My resting pulse is 60-65, though I’m not an active person. I read where the fluid loss during the prep, even while trying to stay hydrated, can cause an electrolyte imbalance. In seniors, that could lead to a cardiovascular event. Then there’s the risk of a perforated colon with the procedure or even with a diverticulitis flare. I decided to cancel my appointment for the scheduled procedure and instead, made an appointment to discuss these issues with my primary care doctor. Perhaps a less invasive screening would be preferable? Would love to know folks’ thoughts and experiences. Thanks!
