I have several (3 - 4) bowel movements during the day. this has developed over time. A medical doctor said that the muscles in my bowels are slowing down due to my age, 76 yrs. I had a prostatectomy in 1998 which, I believe, causes me to need to quickly need to find a toilet. A practical result is I hesitate to travel, since I may not locate a toilet quickly overseas. Had mild diverticulitis attack last August and December of 2014, with Cefdinir last December. A scan confirmed diverticulosis. What type doctor should I see next? Would travel to Cleveland clinic or Mayo Clinic improve chances of successful result?
