Functional Medicine

What is Functional Medicine?

90% of disease is based on diet and lifestyle factors, not genetics.
In spite of spending billions of dollars on research and new treatments, the conventional medical system has failed to address the growing flood of chronic disease.

In order make a difference, we need a new paradigm of health care.

Functional Medicine offers hope for the future.

Functional medicine finds and addresses the cause of disease, using the latest cutting-edge evidence-based and science-based methods.

Here is an example of how Functional Medicine works:

Problem: Patient is suffering from fatigue. Thyroid lab tests show low thyroid.

Functional Medicine solution: Look for reasons why the thyroid is stressed. Perform detailed testing as necessary to determine the cause and explore what diet and lifestyle habits might be contributing to or exacerbating the problem. Provide a comprehensive recommendation that takes the whole person into account. The solution is collaborative. The patient takes an active role in his or her care. All recommendations are safe and natural. The doctor does not consider care a success until the patient actually feels better.

Contrasted with:

Conventional solution: Provide medicine to bring thyroid numbers back into normal range. The patient might not feel better, but the lab numbers are now normal, so she is considered cured. Most of the time the only solution is medication and there is nothing else the patient can do to get better.
