Have you ever noticed that during periods of high work or personal stress, your hormone symptoms get exponentially worse? Sleep becomes fragmented, belly fat accumulates faster, and your mood feels completely unpredictable.
This isn’t a coincidence. It is driven by a biological mechanism known in functional medicine as the “Pregnenolone Steal.”
At Ziva Wellness MD in Scottsdale, Dr. Vini Singh looks at how your adrenal health and sex hormones interact to keep your body balanced under pressure.
What Is the “Pregnenolone Steal”?
All steroid hormones in your body—including cortisol, progesterone, estrogen, and testosterone—are built from the same starting master molecule, called Pregnenolone.
When your brain perceives chronic stress (whether from long work hours, intense exercise without recovery, or poor sleep), your adrenal glands panic. Your body prioritizes survival over reproduction and longevity, rerouting your limited supply of Pregnenolone to manufacture excess Cortisol (the stress hormone).
[Chronic Stress] ➡️ [Pregnenolone Rerouted to Cortisol] ➡️ [Depleted Progesterone & Testosterone] ➡️ [Hormonal Chaos]
The Domino Effect on Your Body
- In Women:Low progesterone relative to high cortisol leads to intense anxiety, heavy PMS, bloating, and early morning wake-ups.
- In Men:High cortisol directly blocks the brain signals (LH and FSH) that tell the testes to produce testosterone, causing a rapid drop in energy, libido, and muscle recovery.
Rebalancing the System with BHRT and Stress Medicine
Simply taking a supplement won’t fix an adrenal system that is running on fumes. Dr. Vini Singh evaluates your full endocrine panel—mapping your cortisol curve alongside your sex hormones—to create a treatment plan that restores your hormonal reserves and builds resilience against daily stress.
