The enteric nervous system controlling the GI tract is part of the autonomic nervous system which is affected in PD. Gastroparesis occurs in most people with PD, as contractions in the GI tract become sluggish. This is why constipation is so common in PD, often appearing years before motor symptoms.
The ways in which Parkinson’s disease can increase the risk of constipation include: lack of dopamine (a neurotransmitter) in the brain – impairs control of muscle movement throughout the body. Bowel muscles can become slow and rigid.
Constipation is a common complication of Parkinson’s disease, but it can be managed with lifestyle changes such as adding extra fibre to your diet, or medical treatment. Many people who have Parkinson’s disease notice difficulties with constipation before they notice motor symptoms such as tremor or stiffness.
I’m going to simply direct you to a document that covers just about every thing about what can help.. except I didn’t see my solution. I take 1 capsule of Tripple Magnesium Complex (ordered from Swansons) along with 1 capsule of Cape Aloe 250 mg (ordered from NaturalHealthySolutions.com) each morning and each evening. Both products attract fluid to the digestive zone helping things to be soft enough that, with digital stimulation, movement can be iniated.
