Functional Medicine is a medical approach which involves testing for the underlying causes of disease and designing a treatment plan to address the root cause of the disorder, not just the symptoms. It views and treats the body as a whole, integrated system. Many factors can lead to illness, such as lifestyle choices, environmental exposures, and genetic makeup, and all factors should be considered for personalized treatment.
At this moment, your unique genetic makeup and that of the people you love can be predisposing you/them to all types of medical and psychiatric disorders, even before symptoms show up. Why live in the dark, hoping and praying that health problems are not sneaking up on you? Now, you can bring the light of inexpensive, often insurance covered, genetic testing into your life and take charge of chronic ailments now, possibly prevent them from happening or put them off for decades.
As the saying goes, If we don't test, we've guessed. Isn't health too important to make guesses about?
