The Prevalence of Constipation and Irritable Bowel Syndrome in Parkinson's Disease Patients According to Rome III Diagnostic Criteria.
Gastrointestinal symptoms are one of the most common non-motor features of Parkinson's disease (PD). Recently, a report from Taiwan revealed that irritable bowel syndrome (IBS) may be associated with an increased risk of developing PD; however, the prevalence of IBS in PD patients has not been fully evaluated. Rome III criteria are widely assessed with a questionnaire to determine functional gastrointestinal disorders.



We assessed the prevalence of constipation and IBS in PD patients in our cohort using Rome III criteria.



Between October 2014 and April 2015, 118 patients with PD were treated at Fukuoka University Hospital and were enrolled in this study. Rome III criteria were used to diagnose constipation and IBS.



Constipation and IBS were detected in 32 (27.1%) and 20 patients (17.0%), respectively. The most common symptom related to constipation was straining during defecation (77.1%). Among constipation symptoms, patients' self-awareness of constipation was mostly related to straining during defecation (odds ratio 5.27, 95% confidence interval 1.475-18.811). The number of constipation symptoms was correlated with the severity of the Hoehn-Yahr Stage (p < 0.05) and total levodopa equivalent dose (p < 0.05).



This is the first report to investigate the prevalence of IBS in PD patients with Rome III criteria. We found a higher prevalence of IBS compared with the general population. The prevalence of constipation based on Rome III criteria was much lower than that reported in previous studies. Further studies are warranted to evaluate gastrointestinal symptoms in PD patients using comparable questionnaires.
