Perimenopause: The Real Hormonal Cascade Explained

Perimenopause is not a single hormone dropping. It is a chaotic, multi-year cascade that begins with progesterone decline, followed by erratic estrogen, rising insulin resistance, and eventual thyroid slowdown.

Most women are told "it's just perimenopause" and offered the birth control pill or nothing at all. That approach misses the real physiology.

The Actual Sequence I See in Practice

1. Progesterone drops first (often in the late 30s)
2. Estrogen begins to fluctuate wildly
3. Insulin sensitivity declines
4. Cortisol rhythm becomes dysregulated
5. Thyroid conversion slows

This is why symptoms can feel random and why standard hormone testing often looks "normal."

My Clinical Approach to Perimenopause

I start with the LCHPMF foundation before any hormone replacement:

• Protein anchoring every meal
• Strategic carbohydrate timing
• Cortisol rhythm restoration
• Gut and liver support

Only after the foundation is solid do we consider targeted hormonal support.

The free 3-minute assessment at Take the free Hormone & Metabolism Assessment will tell you if perimenopause transition is one of your active patterns. You'll receive a personalized Clinical Mirror report and immediate access to LEO for real-time guidance.
