I have SIBO and have been to many doctors. My family doctor said all I have to do is eat yogurt. After losing 45 pounds the doctor from University of Chicago said to go on a low residual diet, then two days of a liquid diet and then drink the colonoscopy liquid for two days. Afterwards, if I have any weight left take the Jona health stool test. I'm going to take the jona stool test after I finish the low fermentation diet. I just transitioned from the low fodmap diet (with fodzyme). The UofC doctor said there is no cure, just management. But I didn't care for his extreme diet and chose the low fermentation diet instead. Nothing else has worked so why not.
