Your Questions, Answered

Functional medicine is a science-based approach that looks for the root cause of your symptoms rather than just managing them with medication. It considers your genetics, environment, lifestyle, and lab work to create a truly personalized treatment plan.

Functional medicine uses advanced lab testing, evidence-based protocols, and a systems-biology approach. While there is overlap with naturopathic and integrative medicine, functional medicine is specifically focused on identifying and correcting the underlying drivers of disease.

Functional medicine addresses a wide range of conditions including chronic fatigue, thyroid disorders, autoimmune disease, gut issues, hormonal imbalances, brain fog, metabolic dysfunction, chronic pain, and more.

Many patients notice improvements within the first 4 to 8 weeks. More complex conditions may take 3 to 6 months of consistent treatment. Your provider will set clear expectations based on your specific situation.

We use advanced panels including comprehensive hormone testing, DUTCH testing, food sensitivity panels, gut health analysis, inflammatory markers, nutrient levels, genetic testing, and more. These go far beyond the standard labs your primary care doctor runs.
