Many people with Parkinson's suffer from constipation (also know as lazy bowels). This does not only manifest in stomach aches after meals, but it can also have other adverse effects. Constipation can cause the medication to not work as they should. The annoying feeling of constipation can also cause the patients to eat less and lose weight unintentionally. Thus, treating constipation is therefore an important part of the treatment of people with Parkinson's disease.
