“Although few Americans have heard of SIBO and SIFO, tens of millions of us are affected by them. We now know that 35–84 percent of the thirty-five million Americans diagnosed with irritable bowel syndrome, as well as the equal number who remain undiagnosed but grin and bear bowel urgency and bloating, have SIBO.6 We also know that of the twelve million Americans with the pain and disability of fibromyalgia, up to 100 percent have the bacterial overgrowth of SIBO, as do the majority of people with restless leg syndrome, fatty liver, diverticular disease, various food intolerances, gallstones, autoimmune and neurodegenerative conditions, and type 2 diabetes.6–12 The bacterial overgrowth of SIBO is also present in about 50 percent of the 150 million American adults who are overweight or obese.13 We also know that about a third of people with SIBO also have SIFO.14 It may not pillage the countryside or terrorize people in their cottages, but it is a monster that modern life has created, and it dwells in the thirty feet of your GI tract.”
