Root cause functional medicine

Ever feel dismissed because your labs are “normal,” yet your symptoms persist?

Functional medicine looks deeper to uncover what standard testing may miss. Standard screening panels are designed to rule out disease, not to measure how well your body is functioning — a result can sit inside a broad reference range and still be nowhere near where you personally feel your best.
We go beyond symptom management to identify and address the root causes of health concerns, using advanced testing, personalized care plans, and evidence-based therapies to help your body restore balance and function.

Frequently asked questions

Before you book

What is functional medicine?

Functional medicine is a systems-based approach that looks at health history, symptoms, lifestyle, and appropriate testing to better understand factors that may be contributing to ongoing health concerns. Care is individualized and can complement conventional medical care.

Conventional medicine is essential for diagnosis, acute care, preventive care, and treatment of disease. Functional medicine adds a broader look at lifestyle, nutrition, metabolic health, sleep, stress, and other factors that may influence symptoms and long-term wellness.

Patients commonly seek support for concerns involving energy, brain fog, hormones, thyroid function, gut health, metabolic health, chronic pain, complex chronic symptoms, healthy aging, and overall wellness. Evaluation and recommendations depend on the individual.
Your first visit focuses on your health history, symptom timeline, previous testing, medications, supplements, nutrition, sleep, activity, stress, and goals. Based on that information, the provider can determine whether additional testing or specific next steps are appropriate.
When appropriate, testing may include conventional laboratory work and selected specialty testing related to hormones, gastrointestinal health, nutrients, metabolism, genetics, or environmental exposures. Testing is chosen based on the clinical question rather than using the same panel for every patient.
Yes. Straight 2 U Wellness offers individualized hormone evaluation and optimization for appropriate patients. Recommendations are based on symptoms, medical history, laboratory findings, risks, benefits, and ongoing monitoring.
