my daughter has ulcerative colitis and has been on a research med. She finally stopped it, at least temporarily, because it is causing so my gas. It will last for about four hours then it is time to eat again. It nausea so much gas that she looke like she is pregnant and can't wear some of her clothes. It doesn't matter what she eats.She has used simethecone, engymes and they don't seem to help. Any other suggestions?
