How It Works

We take time to listen, review your history, and understand your health goals.

When appropriate, we use targeted lab testing to uncover underlying imbalances.

Your results guide a customized plan tailored to your body and needs.

We adjust, support, and optimize your care as your health evolves.

Ever feel dismissed because your labs are ‘normal,’ yet your symptoms persist?

If you’re still dealing with unexplained symptoms, functional medicine looks deeper to uncover what standard testing may miss. Functional medicine goes beyond symptoms to uncover the root causes by evaluating hormones, gut health, thyroid function, inflammation, nutrition, sleep, and lifestyle—so care is truly personalized and lasting.

  • Fatigue or low energy
  • Brain fog or difficulty concentrating
  • Weight gain or trouble losing weight
  • Digestive discomfort or bloating

Frequently Asked Questions

Common Questions

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.
Yes. Persistent symptoms can warrant further evaluation even when routine testing has not identified a cause. A consultation can help organize the full picture and determine whether additional evaluation is appropriate.
