Digestive System

Many people suffering from Parkinson's Disease also suffer from constipation. Digestion slows down with movement in people with PD, leading to unusual bowel movements. People who have difficulty swallowing may be put on a special diet and if the diet has a lack of fiber, constipation occurs. In addition to constipation, nausea is a common effect due to the drugs that help control movement in patients with PD. One last effect that Parkinson's disease has on the digestive system, is bloating. The muscles that move food along through the digestive system may have a slowed response or lack of movement. If the stomach muscles cannot push food through to the intestines, then it can cause a delayed gastric emptying [bloating, nausea, and vomiting].
