Constipation in Parkinson's Disease

by Erik Steel

Overview

In Parkinson's disease, voluntary and involuntary muscle movements are lost or become impaired because of a lack of the neurotransmitter (chemical messenger) dopamine. Constipation is one of the effects of this disease.
Identification

According to the Mayo Clinic and Merck Manuals, constipation occurs in Parkinson's disease because the muscles of the digestive system are working more slowly.

Features

Merck Manuals reports that constipation can be worsened by the Parkinson's medication levodopa (used by the brain to produce dopamine) and by inactivity.
Similar Symptoms

According to the Mayo Clinic, Parkinson's disease can also lead to both urinary incontinence and retention of urine.
Treatment

The following are recommended by Merck Manuals to lessen constipation: eating high-fiber foods and drinking plenty of fluids, exercise and using stool softeners.
Warning

The Mayo Clinic reported in 2009 that chronic constipation may be a risk factor for later developing Parkinson's disease.
