GI issues arise because the autonomic nervous system, which controls automatic bodily functions, is compromised in Parkinson’s, disrupting digestive processes. The most common problem is constipation. Other symptoms include gastroparesis, or delayed gastric emptying, which results in bloating, nausea, and early satiety; dysphagia, or difficulty swallowing; and sialorrhea, or excessive saliva production. Additionally, you may experience bloating and abdominal discomfort due to the slowed movement of food through the digestive tract. Managing these symptoms involves dietary adjustments, medications, and the empowering role of lifestyle changes, along with professional guidance, to improve quality of life.
