i've had stomach problems my whole life... i've tried everything but nothing really has worked. i had a colonoscopy last week and i have IBS-C. I'm continually constipated. Taking Zelnorm, probiotics, and peppermint oil capsules. I'm an extremely healthy eater and exerciser, but recently I have been so bloated I feel I've gained weight.. I'm not sure if it's weight though or just being bloated and constipated... does anyone have trouble with losing weight with IBS-C? it's so frustrating because i eat really healthfully and work out and i feel and look so much heavier than everyone else! any suggestions overall?
