Functional Medicine vs. Traditional Medicine

Traditional medicine focuses on the illness at surface level and often times treats symptoms more than the root cause. This can leave you without a cure for the actual problem. This is where Functional Medicine steps in.

Functional Medicine takes a holistic approach and looks at the bigger picture. It takes into account your psychological, physical, environmental, social, and spiritual situations. Often times, this holistic or integrative approach can help identify the root cause of an illness which can help prevent further or worse symptoms from appearing.
