Detecting the Root Cause of Your Health Issues Through Functional Diagnostic Testing

Regenerative Whole Health Show: Detecting the Root Cause of Your Health Issues Through Functional Diagnostic Testing

As a board-certified health & wellness coach and Functional Diagnostic Nutrition Practitioner, Leslie Parran shows clients how to be a health detective to identify and understand symptoms.

Symptoms are not normal. They indicate imbalance and possible illness. When looking to find the cause of our health issues, we often end up in a cycle of trial and error. And, if we don’t find the root cause of our health issues, we may continue to feel worse.

Leslie Parran joins KnoWEwell’s Chief Health Officer, Dr. Tom O’Bryan to discuss how you can be your own health detective from your own home to find hidden imbalances in your metabolism through functional lab testing.
