The bladder is a muscle, and spasms of the bladder muscle can cause urinary urgency and/or frequency among people with Parkinson's. Lifestyle changes can be of some benefit in reducing OAB; weight loss, reducing consumption of alcohol and caffeine, and reducing fluid intake at night. Pelvic floor strengthening with Kegel exercises can be helpful. Medications can also reduce the bladder spasms of OAB. Possible side effects include headaches, constipation, dry mouth, blurry vision, and urinary retention. Most OAB medications work via anticholinergic effects, and they can have the side effects of anticholinergic medications.
