Why Do I Feel Both Stressed and Depleted — What Is the 'Pregnenolone Steal' in Perimenopause?

Some days it feels like you're floored by exhaustion, but at the same time, your mind is racing with a low-grade hum of anxiety. You're tired, but wired. And honestly? It's a confusing and frustrating place to be.

This feeling of being both stressed and depleted during perimenopause is at the heart of a functional medicine concept known as the 'pregnenolone steal'. The theory suggests that during chronic stress, your body prioritizes making the stress hormone cortisol, potentially diverting the "mother hormone" pregnenolone away from producing other essential hormones like progesterone.

So, What Exactly Is Pregnenolone?

Think of pregnenolone as the starting block for a whole team of hormones. It’s a precursor, often called a 'mother hormone,' because your body uses it to synthesize other critical steroid hormones. We're talking about progesterone, DHEA, testosterone, and yes, cortisol. It’s the raw material. But its job doesn't stop there. Research also shows that pregnenolone plays a part in the body's wellness toolkit, helping to regulate inflammation by promoting the breakdown of key inflammatory proteins in our immune cells. So it's a pretty important molecule, doing a lot of work behind the scenes.

How Does the 'Pregnenolone Steal' Theory Work?

Here's the idea, in plain English. Your body is smart. When it perceives a threat — whether that's a real emergency or the modern-day equivalent of back-to-back Zoom calls, financial worries, and just not enough sleep — it goes into survival mode. Its top priority becomes producing cortisol to manage the stress. The 'pregnenolone steal' theory proposes that to meet this high demand for cortisol, your body might divert its pregnenolone resources over to the cortisol production line. The pathway essentially "steals" the building blocks that might have otherwise been used to make hormones like progesterone. When you're already in perimenopause and your progesterone levels are naturally declining, this added demand from stress can feel like pouring salt in a wound.

But Is This 'Steal' a Proven Fact?

This is where we need to be really clear. The 'pregnenolone steal' is a compelling theory, and it makes a lot of logical sense, but it’s a concept that is debated in the scientific community. It's used mostly in functional medicine to explain a clinical pattern, but there isn’t a ton of direct biological evidence to prove it happens to a degree that significantly drains other hormone levels system-wide. The most important thing to remember is that the primary reason progesterone levels drop during perimenopause is because of declining ovarian function. That is the main event. The stress component is an extra layer on top of a system that's already in a massive state of flux. So while the 'steal' might not be the whole story, the core message holds true: unmanaged, chronic stress makes perimenopause harder.

What This Means for You

So, what do you do with this information? You focus on what you can actually control. Whether it’s a literal 'steal' or just the general havoc that high cortisol wreaks on the body, the bottom line is the same. Managing your stress is not a luxury during this time of life — it’s a necessity for your hormone health.

This doesn't mean you need to eliminate all stress. That’s impossible. It just means finding small, consistent ways to signal to your body that it's safe. It means protecting your sleep like it's your job. It means choosing movement that feels good, not punishing. It means eating enough food, regularly, to keep your blood sugar stable. It means learning to say "no." The name of the theory doesn't matter as much as the reality of how you feel. And if you feel both stressed and depleted, giving your nervous system a break with support from targeted adaptogens like those in GloSerene is the most practical first step you can take.
