What causes frequent bowel movements and bloating?

Three years after radiation for prostate cancer, I had a colonoscopy. This was because there were occasional black stools. One polyp was found. Three years later, another colonoscopy -- this time, all was clear. It has now been another three years and am concerned that I should have another test now. Currently -- and for the past couple of years -- there are frequent bowel movements (usually two per day), as well as excessive gas. The feeling of fullness is almost constant, and the urge to have a bowel movement happens very soon after eating -- sometimes within an hour. The only other symptoms relate to my long-tern acid reflux and to my mitral valve prolapse. Since I had the prostate radiation 9 years ago, my concern is that colon cancer is a possibility. I had been advised to have the colonoscopy every five years, but these symptoms cause me to consider having it now, after three years. MEDS: My current prescribed meds are metoprolol (50mg twice daily), losartan (25mg), and tamsulosin (0.4mg twice daily). Supplements: B-6, Omega 3, Co-Q10, Centrum, Vitamin C, and Biotin. (Male, 68 years.) Thank you.

Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.

I do not think it to be a malignancy. It seems more of a functional cause. But considering your age and history of irradiation and acid reflux, I would suggest both upper and lower GI endoscopy.

Hope I have answered your query. Let me know if I can assist you further.
