Many people with Parkinson’s disease suffer from constipation, so what are the causes of constipation in people with Parkinson’s disease? What should we do when we encounter this situation? The main cause of Parkinson’s disease constipation is the dysfunction of the plant nerves of the digestive tract caused by Parkinson’s disease itself, and the slow peristalsis of the gastrointestinal tract; due to motor retardation, patients with Parkinson’s disease often have less activity and lack of sufficient exercise, which is also not conducive to intestinal motility. This is followed by pharmacogenic constipation, as both anticholinergic drugs (Antanomics) and amantadine significantly slow down bowel movements. Other medications, such as stilbene, dopamine agonists, and levodopa can aggravate constipation, and some patients are even unable to take their medications due to severe constipation caused by levodopa. For pharmacogenic constipation, the first step is to stop or reduce the medication that is causing the constipation. For constipation caused by Parkinson’s disease itself, long-term use of laxatives is detrimental to the body and may worsen constipation. Therefore, the first step to reduce constipation is to use non-drug therapy. First, change bad habits Develop the habit of having regular bowel movements every day, preferably between 5 and 7 am after waking up. Daily defecation avoids the retention time of feces in the rectum, which also avoids the dehydration and hardening of feces in the rectum, making defecation easy. Second, change the structure of your diet Eat enough fiber-containing foods and drink enough water every day. In addition to helping patients prevent constipation, fiber can also lower cholesterol and help prevent many chronic diseases. Foods that contain a lot of fiber include vegetables, fruits, and legumes, especially those with leaves or stalks, such as cabbage, spinach, and celery. You should eat at least 20-25 grams of fiber a day, which is equivalent to eating 500 grams of vegetables. Drinking water is as important as eating fiber. Fiber without water soaking may make constipation worse. So, you should drink at least 4 to 8 glasses of water a day, and you can add juice, milk or other beverages. Regulating your diet is the preferred treatment for constipation, with water and fiber working together to keep your stools open. Third, medication For patients with severe constipation, if the above methods are ineffective, then you should use some medications, such as cork, senna, etc., under the guidance of a doctor.
