Autonomic Body Regulation Issues in Parkinson’s Disease
Autonomic symptoms happen when Parkinson's affects the body's automatic functions - the things the body is supposed to regulate without conscious effort. These symptoms can include blood pressure changes, bladder problems, constipation, temperature dysregulation, skin changes, and sexual dysfunction. This page explains how body-regulation symptoms can affect daily life and why they are an important part of Parkinson's, not a separate problem.
