What is Functional Medicine?
Functional medicine is a patient-centered approach to healthcare that focuses on identifying and addressing the underlying causes of illness and dysfunction in the body. It considers the unique biochemical makeup of each individual and seeks to restore balance and optimize overall wellness. By addressing these imbalances, functional medicine practitioners develop personalized treatment plans that promote long-term health and prevent future health issues.
