I as well have a redundant colon along with adhesions due to multiple abdominal surgeries. Plus I have Pelvic Floor Dysfunction. I am on the Fodmap diet as many others on this site are, however contrary to what most doctors and dietitians say, I avoid all foods that have more than 3 grams of fiber. I used to be a vegetable fanatic. Besides loving them, every Dr said fiber, more fiber and more fiber for the constipation. Fiber, especially insoluble, can't be broken down in your digestive tract. If your colon is twisted as mine is, plus adhesions (adhesions are like glue sticking your intestines together) there is no way for the fibrous food to get through, which ultimately blocks anything else I eat from passing through, causes bloating, pain, and horrible constipation. This goes for corn, popcorn, nuts, and anything with seeds. It just takes one seed or nut to get caught in a loop that is stuck together to cause a complete flare up. I am on Trulance. Trulance is supposed to liquify your stool so it can get pass through. In addition to that I take 2 to 3 caps of Miralax a day. Even with all of these laxatives food in general doesn't get through easily or daily, but fiber is my worst enemy. My bowels are like a yo-yo.
