A percentage of the IBS population exhbits small intestinal bacterial overgrowth ( SIBO ). A standard diagnostic technique for determining if you have SIBO has not been established. Flagyl (metronidazole) is one of the drugs that are used to kill the bacteria responsible of SIBO. Some GI docs think that one method for determining if you have SIBO is to get you to take a course of special antibiotics to see if your IBS symptoms improve.
Did your GI doc talk you about SIBO?
