Your Hormones Aren't the Villain: What Perimenopause Is Actually Doing

Have you had the experience of your body changing on you, seemingly overnight, with no one able to tell you why? One season you recognized yourself. Then somewhere along the way your sleep got worse, your moods got sharper, your weight settled into places it never used to, and the woman in the mirror started to feel like a stranger. If that's you, you're not imagining it. A lot of what you're feeling is connected to your hormones.

On a recent episode of the Living Inspired podcast (listen above), I opened the doors to something I usually teach inside my program. It's the conversation I end up having with nearly every woman who finds her way to me. The one about hormones. Not the version you've been handed on social media, where estrogen is the villain and the right cream or supplement will save you. The real one, where your hormones are one part of a much larger story your body is trying to tell you.

Where Your Hormones Actually Sit

Picture a pyramid. Your hormones live in a hierarchy, and where each one sits tells you almost everything about how to help it. At the very bottom, holding up everything else, is blood sugar regulation. Just above it is insulin, the hormone that manages that blood sugar. Above that are your adrenal hormones, your stress hormones, including cortisol. Above those sit your thyroid hormones. And resting on the very top of the whole structure are your sex hormones, estrogen and progesterone.

Look at where they live. The top. Which means they're the most downstream. The most dependent on everything beneath them working properly.

You cannot stabilize the top of a pyramid when the base is shaking.

Here's what I see over and over. A woman comes to me convinced her estrogen is the whole problem, certain that if she could just find the right hormone or the right protocol, everything would settle. I understand the pull of that. This is a disruptive, disorienting season, and we want one clean answer. But hormones don't work in isolation. They aren't the villain of this story. They're messengers, and they respond to everything else happening in your body.

So we never start at the top. We steady the blood sugar. We support the stress response. We build the base, because a stable foundation gives the hormones up top a far better chance of finding their own balance. This is also why I get cautious when a woman tells me she wants to start hormone therapy while her blood sugar is swinging all over the place. Start at the top of a shaking pyramid and you can make things harder, not easier.

Not a Gentle Decline

Most of us were sold a gentle story about this transition. Estrogen drifts slowly downward, a few hot flashes come and go, and then it's behind you. That is not what perimenopause is.

First, the words, because they get used interchangeably and they shouldn't be. Menopause is one single day. It's the day that marks twelve consecutive months since your last period. That's the entire definition. It's one point on the calendar, looking backward. Perimenopause is the years-long stretch leading up to that day, when your hormones are shifting. It can start in your early to mid-40s, sometimes in your late 30s, and it can last anywhere from a few years to ten years or more. If you're still getting your period but your body feels like it's changing, you're very likely in it. And post-menopause is everything that comes after that one menopause day, for the rest of your life.

Now the part almost no one explains. During perimenopause, estrogen doesn't glide down. It swings. It can spike higher than it ever was in your regular cycling years and then crash to new lows, sometimes inside the same week, month after month, unpredictably.

It isn't the eventual low that drives the hardest symptoms. It's the roller coaster.

Progesterone tends to be the first to go, and there's a clean reason for it. You only make a real surge of progesterone after you ovulate. As you move through perimenopause, you start having cycles where you don't ovulate at all, even if a period still shows up. No ovulation means no meaningful progesterone that month. And progesterone is your calming hormone. It works alongside the soothing systems in your brain. So when it drops, you feel more wired, more anxious, more easily rattled, and your sleep tends to fall apart. That's not in your head. That's the loss of your body's own calming agent.

Estrogen is the one doing the wild swinging, and it does far more than reproduction. Estrogen is neuroprotective. It directly supports your brain and your mood. So when it crashes, you can get the brain fog, the low mood, the irritability, the anxiety, and that maddening word-finding trouble where the sentence is right there and then it's gone. Research suggests that the seasons when estrogen runs low, like postpartum and perimenopause, may bring a real increase in mood symptoms. So when you feel like you've lost a little of yourself, like your brain isn't working the way it used to, there is a physiological reason underneath it. Your brain is adapting to the loss of a hormone it once relied on.

By some measures, estrogen during perimenopause can run up to about thirty percent higher than in your earlier premenopausal years, even as it's crashing to brand new lows. That chaos is exactly why perimenopause is so often harder than menopause itself. Your body handles a stable low far better than it handles a violent swing. It's always reaching for balance, and during these years it can't find any footing.

When the Labs Say You're Fine

You go to your doctor. You say something feels wrong. Maybe they run lab tests, tell you your hormones are normal, and you walk out feeling dismissed and a little crazy. I've been there.

Here's what's actually happening. Behind all of this is a hormone called FSH, or follicle-stimulating hormone. Your ovaries hold a finite number of follicles, and by this stage they're running low. When your brain wants estrogen, it sends out FSH to stimulate those follicles to make it. With fewer follicles answering the call, your ovaries produce less estrogen, so your brain sends out even more FSH, practically shouting to get a response. That's why FSH climbs during this transition. It's your brain raising its voice at ovaries that aren't answering.

Now hold that next to the roller coaster. Your hormones are swinging so dramatically from day to day, even hour to hour, that a single blood draw is one snapshot of a moving target.

A blood draw on a Tuesday morning tells you almost nothing about the whole picture.

You could be tested on a high day or a low day. Even the medical guidelines say a single FSH or estrogen reading is unreliable for diagnosing this transition. Perimenopause is largely diagnosed by your symptoms and your story, not by one number on a page in one moment in time. So if you've been told your labs are normal but you know something has changed, you're probably not wrong. Your experience is valid. Your symptoms are real.

It's the Same Conversation

Here is the thread that ties this whole thing back to the base of the pyramid. Estrogen also helps regulate your blood sugar. It supports how your body produces insulin and handles glucose. So as estrogen becomes unstable in perimenopause, your blood sugar regulation can get harder. You can become more insulin resistant, and your body can start storing fat differently, often around the midsection, which sends so many women searching for what they're suddenly doing wrong. Usually the answer is nothing. The ground underneath shifted.

This is why the blood sugar work is never separate from the hormone conversation. It is the hormone conversation. Supporting your blood sugar is one of the most direct things you can do for your hormone system, because the two are physically linked.

That's also the honest answer on hormone therapy. It can be genuinely helpful and a valid option for many women. It's also nuanced, and it is not a one-size-fits-all fix. Whether it's right for you depends on your history, your symptoms, your risks, and your goals, and that's a conversation for you and a provider who truly understands menopause. I'm not here to tell you to take it or to avoid it. I'm here to tell you that if you're considering it, you still start at the base. You steady the foundation first, so that whatever you build on top of it has something solid to stand on.

What To Take With You

One new understanding. Your sex hormones sit at the very top of the pyramid, which makes them the most dependent on everything below them. Chasing the top while the base is unsteady is why so many protocols disappoint. You support the foundation first, and the hormones get a real chance to settle.

One Next Step

Get honest about where you actually are. Perimenopause, menopause, or post-menopause. Naming it changes how you read your own symptoms, and it's the difference between feeling blindsided and feeling informed.

If you're still cycling, start tracking it. An app works, or a note in your planner works just as well. You're simply learning where you are in your own rhythm, so you can stop being ambushed by your own body and start meeting each phase with what supports it.

Your body isn't turning on you. It's moving through a passage it was built to move through. I've come to see this season not as a malfunction but as an invitation, the years where self-care stops being a nice extra and becomes something you're finally allowed to put first.

You're not unraveling. You're not too much. You're not behind. You're a woman moving through a change your body was designed to cross. Support the foundation. Trust the process.

Lots of love,

Rachel
