I too have redundant colon. I have lost 25 lbs in less than 2 years. I was slim before. Started getting bad constipation about 7 months ago. Primary Dr said it was because I take opioids for chronic pain. I disagreed because I had been taking opioids for 16 years and I take only 25% of what I was taking before and constipation wasn't a problem. I had 2 unsuccessfull colonoscopies and finally a Barium enema showed my colon had so many sharp turns. The last Dr thought I might have colon cancer so it was a relief to hear it is redundant colon, sort of. I am still losing weight. I look like crap. I take Movantik, an opioid antagonist for your guts. protein shakes with a lot of fruit and Miralax once or twice a day. Either no BM or 3-4 explosive BM. I never know what Im going to get. Afraid to go vacation. Im supposed to see a colorectal surgeon in 3 days. Im expecting she is going to suggest colon reduction. Any one had that?
