question: Hi  -  had gallbladder removed 1 year ago.. still many stomach problems,  gnawing pain upper right quadrant, then results in explosive diaherria and vomitting,  horrible pain.  comes almost daily.  now i can only eat white foods - bread rice pasta potatoe etc., as everythign else causes this problem.  i have lost 55 lbs.  (which puts me at normal weight now).  i have had ultrasounds, colonoscopy, and the one down the throat with camera, (sorry can't remember the name of hte procedure) as well as the breath test.  Noone can find any cause for this.. it is a huge problem, i can't leave house without "toilet paper and supplies " fo rthe car etc...  and now becoming housebound to avoid these painful episodes .. any ideas ?
