The Hormone Doctor: The Truth About Cortisol, Estrogen and Balancing Your Hormones

Most of what you've heard about hormone balance, perimenopause symptoms, and hormone therapy online is wrong. That misunderstanding is costing women years of unnecessary suffering through puberty, pregnancy, and menopause stages when effective solutions like testosterone for women already exist and can make a real difference.

Endocrinologist Dr. Gillian Goddard is joining Tamsen Fadal on The Tamsen Show to cut through the noise and explain how your hormonal system actually works and what to do when it feels like it isn't.She breaks down the feedback loop mechanism that keeps your hormones self-regulating, why that process is far more dynamic than any "hormone optimization" trend on social media, and what happens when those loops are disrupted at key life transitions.

In this episode, Tamsen and Dr. Goddard cover:

• What a hormone actually is, and why the feedback loop model changes everything
• The thyroid-immune system connection and why puberty, pregnancy, and perimenopause are your highest-risk windows for thyroid disease
• The late reproductive stage: the perimenopause phase most doctors miss, and why it matters
• HRT vs. birth control for perimenopausal symptoms, and why the right answer depends on where you are in your reproductive stage
• Testosterone for women: what the science actually shows (and what it doesn't yet)
• How to talk to your doctor about perimenopause, hormone therapy, and getting your symptoms taken seriously

If you've ever left a doctor's office dismissed because your periods were still regular but you knew something was off, this episode is for you. The late reproductive stage affects roughly 50% of women between ages 37 and 45, and most women have never heard of it.

Dr. Goddard's message is clear: you don't need to suffer. Whether you're navigating your first period or your last, your symptoms are valid and they can be addressed.
