As a part of non-motor symptoms in Parkinson�s disease (PD), the dysfunctions of the gastrointestinal tract are frequent, being a major complain in the majority of the patients. The aim of our study was to assess the impact of digestive dysfunctions on quality of life in Parkinson�s disease. We included in this study 60 patients with PD, with a disease severity which varied between 2 and 5 on Hoehn and Yahr Scale. Our results showed a low correlation between digestive dysfunctions and the severity of the disease, but a statistically significant correlation between quality of life and the stage of the disease. Also, we observed a statistically significant correlation between digestive dysfunctions and quality of life. Our study revealed that the frequency of digestive dysfunction has correlated with a poor quality of life in any stage of the disease.
