Parkinson Disease Constipation: Causes & Treatments

Anorectal Changes

Research suggests that Parkinson’s disease has an effect on the physiology and functioning of both the anus and rectum. It could cause the bowel muscles to stop functioning properly, making constipation more likely.

Poor Muscle Coordination

Parkinson’s disease weakens the muscles of the bowels and pelvic floor. Resulting in the muscles being unable to contract or a malfunction that makes the muscle relax instead of contracting. These effects of Parkinson’s can make it difficult for a bowel movement to occur.

Poor Posture and Inactivity

Parkinson’s can be as severe as making it difficult for you to maintain good posture, thereby leading to a hunched or bent posture. It can also make staying active a challenge. Both of these factors can make it more difficult to have a bowel movement, leading to constipation.
