7 in 10 Women Miss the Signs of Perimenopause. Here's What That Actually Looks Like
By Diamond, Founder of Muna
I read a survey this week that made me want to forward it to every woman I have ever met.
A telehealth company called Hone Health asked hundreds of women about their perimenopause symptoms and when they realized what was actually happening to them. Seven in ten did not recognize, or were not sure, that what they were feeling was perimenopause at all. Eight percent did not even know what the word meant. More than half said their first symptoms showed up before age 45, and over a quarter noticed changes in their thirties.
That gap between what your body is doing and what anyone ever told you to expect is exactly the gap I started Muna to close. So let's talk about what the data actually says.
It Rarely Starts With Your Period
Here is the part that surprised me most. Only 28% of women listed period changes among their first three symptoms. The most common first signs were hot flashes or night sweats, brain fog or memory problems, changes in body composition, sleep problems, and fatigue, all clustered close together in frequency.
In other words, perimenopause usually introduces itself through your sleep, your focus, or your temperature regulation long before it touches your cycle in an obvious way. If you have been waking up at 3 a.m. for no reason, or losing your train of thought mid-sentence, and your period still looks normal, that does not rule anything out.
Why So Many Women Get Told It Is Something Else
Nearly half of the women surveyed said a doctor attributed their symptoms to another cause first. Of those, most were told it was just normal aging, and some were told it was a thyroid issue or another condition entirely. Dr. Shelly Chvotzkin, an OB-GYN affiliated with Hone Health, put it plainly: perimenopause gets missed because women "aren't aware of how early perimenopause can start," and because, as she said, "regular periods do not automatically rule out perimenopause."
That mismatch has a cost. Among women who first sought hormonal treatment before 45, only 36% actually received it by that age, even though 42% had asked. Nearly a quarter of women delayed care simply because they did not recognize their symptoms as hormonal in the first place, and almost as many said a provider dismissed them outright. Sixty-three percent saw at least two clinicians before getting hormone treatment, and about three in ten saw three or more.
Dr. Chvotzkin called this the practical cost of perimenopause, and I think that is the right phrase for it. It is not just confusing. It is expensive, in time, in energy, and in the years you spend doubting yourself before anyone takes the doubt seriously.
What This Means If You Are an ADHD Brain Riding These Changes
I built Muna for women navigating ADHD and PMDD, and perimenopause is quickly becoming one of the biggest reasons people find us. If your attention, memory, and mood already feel unpredictable some weeks, a hormonal shift that shows up as brain fog or sleep disruption before it shows up as a missed period is especially easy to misread as you "just having a bad month" rather than your body changing. (I went deeper on the biology in how perimenopause affects ADHD.)
This is also why 68% of the women surveyed said no clinician ever explained how these midlife hormonal changes could affect their heart, bones, brain, or metabolic health. Nobody sat them down and connected the dots. If nobody has sat you down either, that is not a personal failing. It is a pattern, and now there is data behind it.
What Actually Helps
None of this is a reason to self-diagnose, and I want to be honest about that. A quick note: nothing here is medical advice, and Muna supports and tracks your symptoms, it does not diagnose or treat any condition. If some of this sounds like your last few months, the next right step is a conversation with a qualified clinician who takes your full symptom picture seriously, not just your period calendar.
What you can do in the meantime is start paying attention to the whole picture, not just your cycle. Sleep changes. Temperature swings. Memory blips. Mood shifts that do not match anything going on in your life. Writing those down, even loosely, gives you something concrete to bring into that appointment instead of a vague feeling that something is off. That is the entire reason symptom tracking exists inside Muna: not to replace your doctor, but to hand you the receipts when you finally get in the room with one.
You are not imagining this. Seven in ten women did not see it coming either, and now you know what to actually watch for.
If you want more of this kind of research translated into plain language, I send a Research Roundup like this every Friday, and a more personal note every Tuesday about what I am learning from actual Muna users. And if you want to start tracking your own patterns before your next appointment, Muna is free for 30 days, no card required at signup.
