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-centered focus of medical practice to a more patient-centered approach, Functional Medicine addresses the whole person, not just an isolated set of symptoms. By looking at the interactions between genetic, environmental, and lifestyle factors, the Functional Medicine model facilitates healing by restoring balance and bringing the mind and body back into alignment.
