Perimenopause: Puberty's Older, More Dramatic Sister

Remember puberty?
The cramps that showed up without warning. The skin that betrayed you overnight. The mood swings that made you cry at the drop of a hat and then rage at your locker minutes later. The "what is happening to me" of it all.
Now imagine that experience again, except now you're managing a career, running a household, possibly parenting kids who are going through their own hormonal chaos. And once again, nobody gave you a heads-up that this was coming.
Welcome to perimenopause symptoms.
And here's the part that really isn't fair: puberty at least had the decency to wrap things up in a few years. Perimenopause? She can last a decade or more before you officially cross the threshold into menopause. That's right. A decade. Of your body slowly shape-shifting while you 2am Google "why do I feel like a completely different person" or "perimenopause symptoms".
So if you've been feeling like something is off but you can't quite name it, keep reading. Because what I'm about to walk you through might explain a lot.
It Starts Earlier Than You Think
Most women hear the word menopause and picture their 50s. Maybe their late 50s. Something for future them to deal with.
But perimenopause, the long, winding lead-up to menopause can start as early as your mid-30s. Your mid-30s. Which means that if you're 38 and your body changed the rules without telling you, the bloating, the brain fog, the sleep that just stopped happening, you're not making it up. You're not just stressed. You're not just tired. Something is actually, physiologically shifting.
The problem is that most of us can spend years in this phase before anyone names it for what it is. We go to multiple specialists for each issue. We're told to eat more fiber. We're asked if we tried meditation or yoga. We're prescribed antidepressants. I don't know about you, but it's kind of giving the "Suck it up buttercup!" feeling. "This is just part of getting older, right?
Wrong.
The Stuff Nobody Warned You About
You probably know about hot flashes. You might know about irregular periods and night sweats. Those are the headlines. But perimenopause and menopause have a whole backstory that rarely makes the brochure.
Did you know that hormonal shifts can change the way your gut functions? That the bloating, the constipation, the feeling that your digestion just completely changed personalities one day, that's not random. Your gut motility is influenced by your hormones, and when those hormones start fluctuating, your gut often responds in ways no one told you to expect.
Did you know that your pelvic floor is affected too? That the urgency, the leaking when you sneeze or laugh or jump, the heaviness or pressure that feels like something is falling out of you, those aren't just things that happen because you had kids or because you're getting older. Hormonal changes directly affect the tissue, the fascia, and the muscular support of your entire pelvic region.
Did you know your joints can ache because of hormonal shifts? That your brain fog isn't you losing your edge, it's your nervous system responding to a changing hormonal environment? That sex might feel different, uncomfortable, or even painful, and it has nothing to do with your interest level and everything to do with what's happening to your tissue?
Did you know that all of these things, the gut issues, the pelvic symptoms, the joint pain, the brain fog, the changes to your skin and sleep and mood and bladder are connected? That they're not ten separate problems requiring ten separate specialists? That they're your body responding to one massive, systemic transition?
Here's what's actually happening under the hood: Progesterone is usually the first hormone to decline, and that drop alone can disrupt your sleep, spike your anxiety, and make your cycles unpredictable. Estrogen doesn't just quietly fade out, it swings wildly, sometimes surging higher than it ever was before eventually dropping, which is why perimenopause can feel like a hormonal rollercoaster rather than a slow wind-down. And testosterone? That's been gradually declining since your 30s, affecting your energy, your motivation, your libido, and your ability to maintain muscle. These three hormones don't just manage your reproductive system, they influence your brain, your bones, your gut, your joints, your skin, your pelvic floor, and your cardiovascular system. So when they start shifting, you don't just feel it in one place. You feel it everywhere.
And here's what I see as a pelvic physical therapist: women walk into our clinic having seen three, four, five providers, each one addressing their one piece. The GI doctor looked at the bloating. The gynecologist looked at the period changes. The urologist looked at the urgency. Maybe someone suggested pelvic floor exercises and left it at that.
But nobody looked at how all of it is talking to each other. Nobody told them that their gut and their pelvic floor share fascia, nerve supply, and blood flow. That when one system is struggling, the other one feels it. That you can't fully resolve the pelvic symptoms without considering the gut, and you can't make sense of the gut changes without understanding the hormonal shift that's driving the whole thing.
Nobody connected the dots, because the dots were scattered across five different clinics.
This Is a Transition, Not a Decline
This is the part that changes everything: Just like puberty, perimenopause and menopause are a transition. Your body is not falling apart. It's not betraying you. It's reorganizing. And just like puberty eventually landed somewhere and you figured out how to live in your new normal, this will too.
But unlike puberty, you don't have to just power through and hope for the best.
Every single symptom I just listed? Treatable. Manageable. Often dramatically improvable, when you understand what's actually driving it and when you have the right team around you.
The bloating that's been dismissed as stress? There are real, specific reasons that's happening and real, specific ways to address it. The pelvic pressure and leaking? That's not just part of being a woman over 40. The painful sex, the urgency, the joint aches, the sleep disruption, none of it is something you just have to live with.
You deserve more than being told this is normal. Because yes, it's common. But common and untreatable are not the same thing.
You Don't Have to Figure This Out Alone
The reason I'm so passionate about this is that I watch women come in after years of piecemeal answers, exhausted and frustrated, and within a few visits everything starts making sense. Not because I have some magic solution, but because someone finally looked at the whole picture. The gut, the pelvic floor, the hormones, the nervous system, the connective tissue; all of it, together, as one conversation.
And that's exactly the kind of conversation that's happening at Putting Menopause on the Map on May 6th and May 12th at the Longmont Museum. I'll be there as the pelvic PT on a panel of incredible local women's health providers: physicians, mental health therapists, a registered dietitian, a naturopathic doctor, strength and conditioning experts all in one room, for two nights, breaking down everything you wish someone had explained to you years ago.
This isn't a lecture from someone you'll never see again. These are local providers you can actually follow up with for care. It's candid, it's surprisingly fun, and past events have sold out, so if something in this post made you think "wait, that's me," this is your room to be in.
Whatever stage you're in perimenopause or post-menopause, there's something for everyone.
And if you're not quite ready to dive into an event but this post lit something up for you, stay tuned. This is Part 1 of a series where we're going deeper into all of it. Your gut. Your pelvic floor. Your bladder. Your sex life. The stuff nobody talks about but every woman going through this transition needs to hear.
Because puberty didn't come with a manual either, but at least this time, you get to be informed.
