I went to see a gastroenterologist in October and he diagnosed me as having IBS, but no tests were done. he based his diagnosis on the symptoms I told him I've been having at the time. how can I know for sure that what I have really is IBS and not something else like Celiac Disease or Crohn's? And if it really is IBS, what besides change in diet can help with easing or getting rid of the symptoms? TIA

no tests ? THEN HOW DARE HE DIAGNOSE U THEN SECOND THIRD OPINION , RESEARCH AND GET TESTS ,

IBS is the diagnosis left after celiac disease and crohns are ruled out. you need to try another doctor and get tested for celiac disease and crohns. a good place to start is look up the celiac disease support group for your area in csaceliacs.org and find the doctor they recommend. Not only will that doctor be able to work with you to diagnose CD but if it isn't CD, probably more likely to help you figure out what it is.

Good luck and wish you better health.
