Just been diagnosed with functional bowel disease. what is it? what's the treamtment, prospects, how does it work?

More Fiber Less Stre: I recommend 1-2 tablespoons of Psyllium Husks (Metamucil, Konsyl) in a glass of water. Drink it fast (otherwise, it will turn to sludge in the glass)--and follow with another glass of water. You should have an easy bowel movement every day. If you're not doing that, you probably need more fiber--and maybe more magnesium (500-1,000 mg/day). Stress may exacerbate the condition.

FunctionalorDysfunct: That's a very big question. First and foremost be sure that's the exact name of your diagnosis. And insist on a discussion with the doctor who gave you that diagnosis. Then read-up on it. If you have any doubts, get a second opinion. I say all this because this diagnosis could be with you for life and involve certain therapies, diets and medications so you want to be sure it's what they called it.
