Functional Medicine is an integrative and complimentary (holistic) healthcare approach that treats illness and promotes wellness by focusing on the biochemically unique aspects of each patient and then individualizing interventions designed to restore physiological, psychological, and structural balance.
It takes into consideration fundamental physiological processes, environmental factors, and genetic predispositions that influence health and disease. Interventions are aimed at treating the 'root cause' of manifested problems rather than treating symptoms in isolation from their root causes.
