    Hormones & Thyroid Center: Hashimoto's, Perimenopause & Low Testosterone

    Your labs were 'normal' and you still feel flat, heavy, anxious or wired. Hormones do not break on their own. They respond to gut health, blood sugar, stress, toxins and sleep. This center connects those dots and gathers everything we have published on thyroid, sex hormones and adrenals.

    Signs your hormones need a closer look

    • Fatigue, weight gain or feeling cold despite "normal" thyroid results
    • Heavy, painful or irregular cycles; PMS that takes over your week
    • Sleep that breaks at 3am, hot flashes, anxiety that arrived with perimenopause
    • Low drive, low motivation and losing muscle in men
    • Wired at night and exhausted in the morning

    What sits underneath hormone imbalance

    1. Thyroid and autoimmunity

    Hashimoto's is autoimmune. Looking only at TSH can miss it; antibodies and the full thyroid picture matter. See the Autoimmune & Skin Center.

    2. The gut and liver

    Estrogen is cleared through the liver and gut. When either is congested, hormones recirculate. See the Gut Health Center.

    3. Stress and cortisol

    Chronic stress pulls resources away from sex hormones and disrupts thyroid conversion.

    4. Toxins

    Mold and endocrine-disrupting chemicals can interfere with hormone signalling. See the Mold & CIRS Center.

    Frequently asked questions

    Why do I feel hypothyroid when my TSH is normal?

    TSH is one signal. Free T3, free T4, reverse T3 and thyroid antibodies can tell a different story, and conversion is affected by stress, nutrients and inflammation. Discuss the full picture with your clinician.

    Can perimenopause cause anxiety?

    Yes. Falling and fluctuating progesterone often shows up first as anxiety, poor sleep and irritability, sometimes years before cycles change.

    Does the Root Cause Snapshot test my hormones?

    No. The $47 Root Cause Snapshot is a written root-cause read with no lab testing. Hormone and genetic testing happen in DNA Precision and Private Concierge.

    Should I stop my thyroid or hormone medication?

    Never change a medication without the prescriber who manages it. Root-cause work runs alongside your existing care.
