 I have done a lot of research lately about the benefits and disadvantages of fibers in the diet of those who suffer IBS. There is so much conflicting information that I don't know if I am coming or going. Examples:
 Fiber Supplements such as Metamucil are sold as a " Laxative and and Dietary Fiber Supplement." It contains 2.4 grams of soluble fiber in each serving so since it is sold as a laxative one would be prone to think that it indicates that soluble fiber alleviates constipation. Also Metamucil,  along with most other fiber supplements contains psyllium husk (of which they brag about I might add) while conflicting statements say that psyllium husk is not well tolerated by IBSers who have bloating and/or gas, which many do.
 One source says that soluble fiber treats both diarrhea and constipation and keeps the system regular. Another source states the soluble fiber is best suited for those with constipation while, I swear, another says that soluble fiber is best suited for those who suffer diarrhea. One says  insoluble fiber is best for constipation.
 I know it is a crazy world out there but who are we to believe?
 Anyone clear on this? I am really confused.


I told my psychiatrist that everyone hates me. He said, "That cannot be true. You haven't met everyone yet!"

I have read that soluable fiber is best for constipation and insoluable is best for diarrhea. Soluable fiber helps make stools softer and wetter--what people with C, but not D, want. Insoluable fiber adds bulk to stools which is what D people want.

All fiber supplements have both kinds in them (all fiberous foods have both kinds), but some products lean more towards one kind of fiber than the other, so you need to pick the one that's a majority of the type that you need for your problem.

A number of people on here are taking the psyllium husks and like it better than any other type of fiber. So I guess it's like everything else about IBS: everything affects people in different ways.
