There is another disease called Habba Syndrome that not all doctors are aware of and I think some doctors can mistake it for IBS. I am insisting on being tested for it at my yearly physical because less than a year ago I was diagnosed with IBS without any tests--I do not get constipation, but severe diahrea.

Habba Syndrome is a disease characterized by chronic diarrhea and caused by a dsyfunctional but still intact gall bladder, characterized by three or more watery bowel movements per day. Anyone interested should check out http://www.encyclocentral.com/14919-Habba_Syndrome_Gall_Bladd
