Anyone who deals with life-time constipation will have a "redundant" or "tortuous" colon. All that means is that it has basically stretched out of its anatomically correct position and has a few more loops and twists. Usually, it's not that big of a deal unless the colon twists like a kink in a garden hose and cuts off the blood supply. Believe me - you'd KNOW it if that happened! I lost a good chunk of colon to just that situation.
The worst part of a redundant colon is that it causes even more constipation because there's that much more mileage for the stool to travel and thus get even more dried out. A real vicious circle. All you can do is keep yourself as regular as you possibly can. Hope this info helps a bit.
