According to clinical data on non-motor symptoms in Parkinson’s disease patients, 85% of Parkinson’s disease patients have urinary tract dysfunction, with urinary urgency and nocturia being the most common non-motor symptoms. Urinary symptoms mainly include urinary urgency, frequency, incontinence, urinary retention; and obstructive symptoms such as delayed urination, straining to urinate and other urinary disorder problems. Some Parkinson’s patients intentionally drink less water in order to control the symptoms of frequent urination, which is inappropriate and can easily cause dehydration in the body. During the daytime, you should drink water regularly, not because you are afraid of going to the bathroom. You can go to the bathroom to relieve urine in advance, not when you have the urge to urinate. In order to reduce the frequency of urination at night, you can slightly control the amount of water you drink after dinner; some patients are in a hurry to go to the toilet at night because of frequent urination and are prone to fall, so you can prepare a portable urine catcher in your bedroom for easy use. In addition, there are some diseases such as urinary tract infection and prostate hyperplasia that can cause frequent urination. If in doubt, you should go to the hospital as soon as possible to clarify the cause of frequent urination and treat it promptly. Overactive detrusor muscles are common in patients with Parkinson’s disease, and patients often complain of urinary urgency, which is caused by an underloaded amount of urine in the bladder, aggravated by dopamine stimulation. To improve constipation in Parkinson’s patients, increase the fiber content of food, such as various vegetables, do not always eat refined rice and pasta, you can appropriately increase coarse grains, the increase in dietary fiber can make the intestinal contents swell, which is conducive to defecation. Appropriate increase in water consumption, also has an improvement effect on constipation. Moreover, cool water can stimulate gastrointestinal peristalsis, which is sometimes helpful for constipation. Patients can decide whether to drink it according to their own situation. Every morning after waking up, drink 1 to 2 glasses of water to stimulate intestinal peristalsis; after breakfast, go to the bathroom for 10 minutes, even if there is no intention to go to the toilet, to form a habit, which is conducive to the improvement of constipation symptoms. In addition, a moderate amount of exercise every day can also be conducive to reducing constipation.
