Functional medicine addresses the underlying causes of disease, using a systems-oriented approach and engaging both patient and practitioner in a therapeutic partnership. It is an evolution in the practice of medicine that better addresses the healthcare needs of the 21st century. By shifting the traditional disease-centred focus of medical practice to a more patient-centred approach, our Functional Medicine Clinic in Whitby, Markham focuses on the whole person, not just an isolated set of symptoms.
