Wow, what a great board. Here's my story. I am 6 months post RNY gastric bypass and have had chronic D ever since I received the surgery. Weight continues to fall at a high rate despite good eating. I tried low fat and Gluten diet, but makes no difference. GI doc has tried me on pancreatic enymes, Welchol, Flagyl, and now Lotrenex (2 days little improvement so far). Do you think it's possible to get IBS from this surgey? Only 20 inches of small intestine was bypassed, I have read that you can lose up to half your small intestine and still function normally. Anyway, I am really starting to hate my life and am begining to lean toward trying to get this reversed. I would rather be fat and healty (I know) than thin and sick all the time. Also I am so impatient for things to work. If I do not see improvemnt in 2-3 days I figure it will not work for me. Is this irrational thinking on my part. I am already on an anti-depressant for this and want to do everything I can to get better. Many thanks for all the wisdom and sharing on this board. BestTom
