Had sigmoid yesterday. Had very bad time with the prep. Colon went nuts. Began with diareha (sp?) at 7:30 p.m. that went non stop until 8:00 a.m. Then started up again after procedure. Anyway, stool sample showed lot of yeast. He has put me on Nyestin (sp?) and continue with Flagyl. Anyone else dealt with yeast in bowels?
