Autonomic dysfunction is common in patients with Parkinson disease. Orthostatic hypotension often becomes a concern in late disease, and impaired intestinal motility can lead to constipation and, sometimes, vomiting or impaired absorption. Urinary symptoms, retention, and bladder infection can occur, and erectile dysfunction is not uncommon. In addition, many patients note episodes of sweating.
