I have been suffering from chronic diarrhea mixed with nausea, abdominal bloating and painful bowel movements, for the last 6 months. i have seen 2 different gastro doctorsand have undergone numerous tests. what could it be?

What did they say?: Sounds like you've been struggling -- what have your doctors shared with you? One thought: as part of the "numerous tests" you've had, have you been through a trial of elimination diet to check for food sensitivities? For instance, even if you don't have celiac you could still be sensitive to gluten. Or you could be dealing with ibs, needing overall program. Hoping you'll confer with local docs.

IBS: If everything turned out normal, i suspect irritable bowel syndrome (ibs).

We may not add: To what your two gastroenterologists told you . You already have second opinion so you must have a good idea of what is going on . My advise would be stick to the one you felt is empathic , feel for you . Good luck.
