Small intestinal bacterial overgrowth has been found to be highly prevalent in Parkinson's Disease. Parkinson's Disease is associated with gastrointestinal motility abnormalities that could favour the occurrence of small intestinal bacterial overgrowth. The aim of this study was to assess the prevalence of small intestinal bacterial overgrowth in people with Parkinson's Disease. The prevalence of small intestinal bacterial overgrowth was far higher in people with Parkinson's Disease. It occurred in over half (54%) of all people with Parkinson's Disease, in contrast to only 8% of people that do not have Parkinson's Disease. The severity of Parkinson's Disease was also very significantly related to small intestinal bacterial overgrowth. This can lead to the following symptoms : excess gas, abdominal bloating and distension, abdominal pain, and diarrhea or in some cases chronic constipation.The researchers suggest that the gastrointestinal motility abnormalities that often occur in Parkinson's Disease might explain this association.
