For patients with Parkinson's disease, we advocate comprehensive treatment and full-course management. Drug treatment is the core treatment method, while surgical treatment can supplement drug therapy. Physical rehabilitation and psychological therapy should also be conducted. What should patients with Parkinson's disease avoid eating? Generally, patients with Parkinson's disease are prone to constipation. Therefore, we should avoid consuming spicy and greasy foods that may lead to constipation, and try to eat vegetables and fruits to keep the bowel movements regular.
