One of the most disorienting things that can happen to a person is googling a symptom, finding nothing helpful, and then eventually discovering — sometimes years later — that what you were experiencing had a name the whole time.
That’s perimenopause. And the reason so many of us don’t know about it is because the women who came before us didn’t really have a platform to talk about it. Well. We do. So let’s go.
This isn’t a doom list. It’s a what-the-heck-is-happening list. Because the more you know going in, the less likely you are to think you’re losing your mind when your body starts doing weird stuff in your forties — or even your late thirties.
What even is perimenopause — and when does it actually start?
Perimenopause is the transition phase before menopause, and it can start anywhere from your late 30s to your mid-40s — sometimes earlier. According to the Mayo Clinic, it can last anywhere from a few years to over a decade. Yes. A decade.
Menopause itself is just one day — the day that marks 12 consecutive months without a period. Everything before that is perimenopause. Which means most of the chaos? Happens before the finish line.
And yet somehow this is not information that gets handed to us. We just… find out. Usually while already in it.

Why does nobody talk about the rage?
The hot flashes get all the press, but the rage — the sudden, inexplicable, disproportionate fury at completely ordinary things — is what actually catches people off guard.
Estrogen affects serotonin. When estrogen starts fluctuating wildly (which is what perimenopause is, essentially — hormonal chaos, not a smooth decline), your mood regulation goes with it. So you’re not “overreacting.” Your brain chemistry is genuinely different on a given Tuesday than it was the Tuesday before.
That’s worth knowing. It doesn’t make the rage okay to unleash on unsuspecting people, but it does make it explainable. And explainable is a lot easier to work with than “I think I’m just becoming a terrible person.”
The brain fog is real and it is rude
Midlife cognitive fog is one of the most documented and most dismissed symptoms of perimenopause. You walk into a room and have absolutely no idea why. You lose words mid-sentence — not small words, big important words that you’ve known your whole life. You read the same paragraph four times.
A study published in Menopause journal found that cognitive complaints are strongly associated with perimenopause — and that they tend to improve after menopause. So it’s a phase, not a permanent state. But when you’re in it, it feels permanent.
Write things down. Be patient with yourself. And for the love of all things holy, stop apologizing for it in meetings.
Is the insomnia hormonal or am I just stressed?
Both. And also they make each other worse, which is genuinely cruel.
Progesterone has a sedative effect, and as it drops during perimenopause, sleep gets harder to come by. Add night sweats (which are just hot flashes that happen while you’re horizontal) and you’ve got a situation where you’re exhausted all day and then inexplicably wired at 2am.
This isn’t insomnia in the traditional sense — it’s hormonally driven sleep disruption. Which means the usual advice (no screens before bed, chamomile tea, a consistent bedtime) helps a little but doesn’t solve it. Talk to a doctor. A real one who takes this seriously. Those exist.
Your period gets weird before it goes away
This is the one that sends a lot of people to the internet in a panic. Periods in perimenopause don’t just get lighter and then stop. They get unpredictable. Sometimes heavier. Sometimes way heavier. Sometimes two weeks apart. Sometimes skipped entirely.
All of that is in the range of normal — but “normal” is a wide range, and anything that feels extreme is worth checking out. Fibroids, polyps, and other things can also cause heavy bleeding, and perimenopause doesn’t make you immune to those. Get your stuff checked. Don’t assume it’s just hormones.

Does anxiety get worse during perimenopause?
For a lot of people, yes — and it often comes out of nowhere. People who have never had significant anxiety suddenly find themselves dreading things they used to do without a second thought. Social situations. Driving somewhere unfamiliar. Meetings.
Again: this is hormonal. Estrogen plays a role in regulating the brain’s fear response, and when it fluctuates, that regulation gets shaky. It doesn’t mean you’re developing an anxiety disorder. It means your hormones are doing something and your brain is along for the ride.
Knowing that doesn’t make it less uncomfortable. But it does mean you’re not broken.
The weight redistribution nobody asked for
This one is aggravating because it happens even when nothing about your habits has changed. Perimenopause shifts fat storage patterns — specifically toward the abdomen — thanks to dropping estrogen levels. It’s not about calories in or miles run. It’s biology doing a thing you didn’t vote for.
Some things that actually help: strength training (building muscle increases insulin sensitivity), prioritizing sleep (poor sleep makes cortisol worse, which makes abdominal fat worse), and honestly just making peace with the fact that your body is in a transition.
I’m not going to tell you to love it. That’s a lot to ask. But understanding why it’s happening is at least a start.
Why do doctors keep dismissing perimenopause symptoms?
This is the question that makes me the most annoyed, and I think it’s worth saying directly: a lot of doctors — including a lot of women’s health doctors — are not well-trained in perimenopause. Medical education historically underinvested in menopause medicine, and it shows.
The Menopause Society (formerly NAMS) has been pushing for better training for years. But right now, you may walk into an appointment describing fatigue, mood swings, irregular periods, and sleep issues and walk out with a referral for anxiety medication and a pamphlet.
Advocate for yourself. Ask specifically about perimenopause. Ask about hormone levels. Ask about HRT. Come in knowing the vocabulary, because that changes how the conversation goes. And if your doctor isn’t listening, that’s useful information too — about that doctor.
What about HRT — is it actually safe?
Hormone replacement therapy got a bad reputation from a 2002 study that scared a lot of people and a lot of doctors off of it for twenty years. Here’s the thing: that study has been significantly reanalyzed and its conclusions largely walked back for most patients, particularly those who start HRT earlier in the transition.
The current guidance from the Menopause Society is that for healthy women under 60 or within 10 years of menopause, the benefits of HRT generally outweigh the risks. That’s not a blanket statement for every person — individual health history matters — but the old blanket “HRT is dangerous” narrative is outdated.
This is a conversation to have with a doctor who actually knows perimenopause medicine. Not a quick dismissal.
The skin and hair changes are also hormonal (not just aging)
Drier skin. Hair that suddenly has a different texture, or thins in places it didn’t before. Nails that break differently. These are estrogen-related changes, not just generic aging. Which means they often respond to the same interventions — including, in some cases, topical estrogen.
The beauty industry sells a lot of expensive products to perimenopausal women by framing these as “signs of aging.” Some of those products help. But knowing the actual cause is useful, because it expands your options beyond a $90 serum.
Does perimenopause affect your sex drive?
Yes, and in more than one way. Lower estrogen means vaginal tissue can become thinner and drier, which makes sex uncomfortable — and discomfort is a pretty effective libido killer. But there’s also the layer of just being exhausted and emotionally scrambled from everything else on this list, which doesn’t exactly set the scene.
This is treatable. Local estrogen (applied directly rather than systemically) is safe for most people and highly effective. Lubricants help. Communication helps. The main thing is not to just accept it as inevitable and permanent when there are actually options.
The symptoms nobody told me to connect to perimenopause
Joint pain. Heart palpitations. Tinnitus. Dry eyes. Itchy skin. These are all documented perimenopause symptoms that most people never connect to hormones because nobody told them to.
I cannot stress this enough: when estrogen fluctuates, it affects basically every system in the body — not just the reproductive one. Estrogen receptors exist in joints, the heart, the eyes, the ears, the skin. So the weird stuff that starts happening in your 40s that seems totally unrelated to “women’s health”? Check the list. It might be connected.
What’s actually helpful right now — besides waiting it out?
Strength training is probably the single most evidence-backed thing you can do for perimenopausal symptoms across the board — it helps with weight, mood, sleep, and bone density. It’s not a cure, but it’s real.
Beyond that: find a doctor who specializes in menopause medicine, look into my notes on how I started actually taking my health seriously again because that shift matters, and stop treating this like something to be embarrassed about or whispered around. We’re the pioneers of blogging — we literally built the infrastructure for oversharing on the internet — and yet somehow this particular overshare has been missing.
Not anymore. Talk about it. Loudly. Your future self will be grateful, and so will every woman reading this who thought she was alone in the weird.
Perimenopause isn’t the end of anything — it’s a transition, and transitions are survivable. The hard part is doing it without information, which is exactly why it needs to be talked about more.
If you’ve been googling symptoms and feeling like you’re not finding yourself in the results, that’s not you. That’s a gap in the conversation that we can actually fix.
But what do I know? I’m just a blogger who’s tired of watching women figure this out alone.
