The past year has been a nightmare for me. It is getting increasingly worse by the day. I went in last October for a colonoscopy and my doctor had to immediately stop the proceedure. He said that he has performed over 30,0000 proceedures and has never seen a more twisted, turning, redundant colon. He obviously could not complete the proceedure because the risk of perforation wes too high. I had a barium enema a couple years ago and the photos were inconclusive due to the fact that the barium was stuck in too may loops in my excessively redundant colon.I have been suffering greatly with extreme bloating, constipation, nausea, back pain, unusual weight gain in-spite of eating only 1,200 calories a day and walking for 30 minutes a day. And I also have a general ill feeling a great deal of the time. Now I am suffering from depression from the weight gain and a huge abnomin. (I look like I am six months pregnant especially in the afternoon and evening)I have had many tests (Cat Scan, Abdominal utrasound, blood work etc...) All came back normal, yet I look and feel terrible. My doctor perscribed zelnorm and that has not helped. Only noticed improvement for the first couple days. Have been taking zelnorm now for 5 weeks. I have been taking herbal laxatives & colon cleaners which have helped with the constipation. Now I can have a bowel movement every other day instead of every 9 days. Whenever I have a bowel movement. My heart is racing and I feel so ill, I have to lie down for a bit afterwards.Is this IBS? If so, what can I do to put a stop to the extreme bloating and weight gain? (I have gained 16 pounds in the past 8 months. For many years I was a consistant 124 pounds so this is very unusual for me.Any help to remedy this problem would be greatly appreciated!!
