Previous research has reported a high prevalence of small intestinal bacterial overgrowth in people with Parkinson’s Disease. A new study has just been published that sort to confirm those findings using a large (103) cohort of patients. The patients were given the hydrogen breath test to assess whether they had SIBO. The result was that 25% of the patients tested positive. Furthermore the authors suggested that having SIBO might worsen motor function.
