That happens to me any time I eat something containing chicory root, which is a fiber-dense but low-calorie additive put in a lot of fiber diet foods, like anything made by Fiber One. Stomach pains, severe bloating, gas, then an unpleasant exit. Are you eating any of those sorts of products? If so, try excluding them and getting your fiber from more natural sources like veggies, grains, and fruits, and read labels on any diet food with a fiber content because they like to sneak it in there to bump up the attractiveness of the nutrition label.
