Study Synopsis
This pilot study will determine the efficacy of a novel supplement protocol and low FODMAP diet for the treatment of small intestinal bacterial overgrowth (SIBO). The study will operate as a prospective, open label investigation, with an estimated sample size of 10 patients.
Patients diagnosed with SIBO by Dr. Nathan Morris, MD at Good Medicine Clinic (Oxford, Ohio) will be offered the opportunity to enroll in this study, if inclusion and exclusion criteria are met upon initial diagnosis. No control group will be assigned.
The diagnosis of SIBO will be determined via assessment of clinical symptoms and the results of a lactulose breath test. After administration of the supplement therapy and adherence to a low FODMAP diet (8 weeks), the lactulose breath test will be repeated and symptoms re-assessed by Dr. Morris. The post-treatment lactulose breath test and all supplements in the protocol will be provided free-of-charge to enrolled patients. In addition, enrolled patients will not be billed for the mid-treatment office visit. Patient and/or patient insurance will be responsible for all other expenses, including but not limited to the initial breath test, all other office visits and travel.
