I just went to a specialist yesterday. Previously I tested positive for lactose and fructose. He didnt want to listen to my ideas about sibo. He was babbling about something in my hydrogen levels in the fructose test, so therefore I dont have sibo. All's I want is to be tested for it. I dont know what else to do. It can get very frustrating...as many of you probably know. Anyways, for the sibo test I think i need to do a lactulose breathing test. Is that all? Any input would be appreciated. Thanks
