I had a volvus (twisted bowel) five years ago and my colon never regained function. I have since had many hospital stays and surgeries, the last one resulting in a total open colectomy. That surgery resolved my dehydration issues but did nothing for my severe constipation. I am one of those rare people who developed "gut paraylisis" folowing a volvus. From trial and error and many forum suggestions I came across a "morbid obese" medication called "xenical"...It has been a answer to my prayers...It takes the fat from the meal and places it outside the stool allowing me to have a near normal bowel movement. I have tried hundreds of other medication over the last five years and this is the only medication I have had any success with. My insurance will not cover a penny of this very expensive medication because I am being prescribed it for an "out of range" use. My doctor has prescribed it and submitted it again and again to my insurance without success. The last time the insurance company asked for two other patient cases for the same use...If anyone out there is using this medication for constipation please...Please...Let me know. Thank you so very much. In addition if a doctor has prescribed it for this use, please let me know. My doctor would love to talk to you.
