WHAT WE TREAT

How we can help you

Comprehensive Diagnostic Testing

Expanded lab panels to evaluate complete hormone cascades (estrogen, progesterone, testosterone, DHEA, and cortisol), thyroid function, metabolic markers, and nutrient deficiencies. We find the right solution for your unique body

Bioidentical Hormone Replacement Therapy (bHRT)

custom-compounded or FDA-approved bioidentical hormones (molecularly identical to those produced naturally by the body) to restore optimal balance and relieve severe symptoms like hot flashes, brain fog, and night sweats.

Gut Microbiome & Estrobolome Optimization

Since the gut microbiome contains specific bacteria (the estrobolome) that metabolize and regulate circulating estrogen, treatment often includes targeted probiotics, dietary adjustments, and GI repair to ensure proper hormone clearance and reduce estrogen dominance or inflammation.

Adrenal & Cortisol Support

Chronic stress drains the adrenal glands, which are responsible for producing backup sex hormones as the ovaries wind down. Functional protocols incorporate adaptogenic herbs, targeted micronutrients (like Vitamin C, B-complex, and Magnesium), and nervous system regulation to support adrenal health.

FAQs

How do I know if I’m in perimenopause or menopause?

Perimenopause can begin as early as your late 30s or 40s and is characterized by changing period cycles, sudden hot flashes, brain fog, sleep shifts, or unexplained anxiety. Menopause is officially diagnosed after you have gone 12 consecutive months without a menstrual period. Comprehensive diagnostic lab work is the most accurate way to pinpoint exactly where you are in the transition.

How does functional medicine differ from traditional menopause care?

Traditional medicine often takes a reactive, "wait-and-see" approach or offers a standard, blanket prescription once symptoms become severe. At ReTreat, we take a proactive, root-cause approach. We evaluate your complete hormonal ecosystem—including thyroid, adrenals, and gut health—to design a fully personalized protocol that addresses why your symptoms are happening in the first place.

Do you accept health insurance for these visits?

We provide detailed superbills upon request that you can submit to your insurance provider for potential out-of-network reimbursement.

Are bioidentical hormones safe?

Bioidentical Hormone Replacement Therapy (bHRT) uses hormones that are structurally identical to the ones your body produces naturally. When prescribed based on precise, comprehensive lab testing and monitored closely by qualified clinicians, bHRT is a safe, evidence-based tool for restoring optimal balance and relieving debilitating symptoms.
