Functional Medicine

If you are searching for leading functional medicine doctors in North Charleston, the Center for Occupational and Environmental Medicine (COEM) should be your preferred choice. With our patient centered care system and professionalism, we ensure our patients have and maintain healthy lives.

How Is Functional Medicine Different?

The main objective of functional medicine is to identify and tackle the root causes of diseases by viewing our body as one integrated system instead of a collection of different independent organs. It treats the whole system, not just its symptoms. In other words, functional medicine is a more patient-centered approach than the disease-centered method of traditional medical practice.

Why do we need Functional Medicine?

We need functional medicine because traditional medicine practiced by most physicians is oriented toward acute care of medical conditions. Unfortunately, this method lacks proper tools and methodology for preventing and treating chronic diseases.
