How Does Parkinson’s Disease Affect the Digestive System?
Parkinson’s disease is a very critical condition that affects almost the entire body, including the brains and digestive system. Researchers still struggle to understand the connection between the disease and some affected part of the body.
Effects of Parkinson’s disease to the body, which contributes to constipation include:
Lack of Dopamine
Dopamine  is a neurotransmitter that is involved in controlling muscle movements. It sends signals to the brain to help your muscles move.
People with Parkinson’s experience a lack of dopamine. When the body is lacking in enough dopamine, it makes it difficult for the bowel muscle to push matter through the GI tract, leading to constipation.
