Functional Medicine


Functional Medicine at Cavallo Health 

Functional medicine determines how and why illness occurs through advanced diagnostic testing. Having a clear understanding of the genetic, biochemical, and lifestyle factors that contribute to your health, allows patient and practitioner alike to understand the complexity behind certain symptoms and illnesses. After identifying the underlying causes of disease, the patient and the practitioner are empowered to collaborate and create a personalized treatment plan. 


You may find that one condition has many different causes and, likewise, one cause may result in many different conditions. For instance, you may have an imbalanced gut microbiome that is triggering inflammation throughout your body, giving you digestive issues but also shoulder and back pain. By identifying the root cause, the patient is empowered to heal and reach optimal, pain-free health.
