Living with Parkinson’s Dr. Dolhun Talks PD The Gut and Parkinson’s Rachel Dolhun, MD, is a movement disorder specialist, board-certified neurologist and vice president of medical communications at MJFF. For a brain disease, Parkinson’s may have a lot to do with the gut. People with Parkinson’s disease (PD) can experience symptoms across the entire digestive system, from swallowing problems to slow stomach emptying to constipation. These non-motor symptoms not only affect daily life, they influence how well Parkinson’s medications work. Coughing or choking when swallowing can make eating meals and taking pills challenging. Slowed stomach emptying can lead to nausea, heartburn and feeling full after only a few bites. It also can cause poor absorption of Parkinson’s medications, which means a dose may give little or no benefit. Constipation, too, can impact drugs’ absorption and effectiveness, and cause bloating and discomfort. The effect these symptoms have on patients’ quality of life has made this topic a growing priority for researchers and The Michael J. Fox Foundation (MJFF). HOW PARKINSON’S AFFECTS THE GUT Parkinson’s affects a network of nerves that direct swallowing and digestion. This network — the autonomic nervous 12 The Fox Focus system — also controls blood pressure and body temperature. It keeps our bodies running so we don’t have to think about it. When Parkinson’s affects these nerves, swallowing becomes uncoordinated and gut muscles slow down. FINDING NEW WAYS TO MANAGE SYMPTOMS Available treatments for Parkinson’s gut symptoms
