The stages of menopause: the STRAW+10 timeline
The 7 stages of menopause isn't a medical model. Doctors use STRAW+10, which splits reproductive aging into the late reproductive stage, the early and late menopausal transition (perimenopause), the final period, and early and late postmenopause. In everyday terms there are 3 stages: perimenopause, menopause and postmenopause. Your stage is read from your cycle pattern: cycles varying by 7 days or more, then gaps of 60 days or more.
The '7 stages' idea isn't a medical model. Doctors use STRAW+10: late reproductive, early and late transition, final period, postmenopause. Find yours.
The stages of menopause: expectation vs reality
What people often expect
“There are 7 clearly defined stages of menopause”
What the evidence shows
The widely shared 7 stages come from popular articles, not research. The international standard, STRAW+10, was agreed by scientists from five countries after reviewing cohort data, and it's designed to apply regardless of age, ethnicity, body size or lifestyle. It stages women mainly by bleeding pattern, with hormone tests as supporting criteria. Its stages are what doctors and researchers mean when they talk about where you are.
The different stages of menopause, step by step
Why doctors use STRAW+10 stages, not 7 stages
STRAW+10 is the international staging system for reproductive aging. It was updated in 2011 by scientists from five countries, who reviewed cohort studies on menstrual cycles and hormone markers such as FSH, AMH, inhibin B and antral follicle count. It stages women mainly by bleeding pattern, backed by hormone tests, and is meant to apply regardless of age, ethnicity, body size or lifestyle. It is used in research and to guide decisions about fertility, contraception and care.
Late reproductive stage: before perimenopause
The late reproductive stage, Stage −3, is when fertility begins to decline, although periods are still regular. In its first part, −3b, cycles don't change, but markers of egg supply such as AMH and antral follicle count are already low. In the second part, −3a, cycles may get subtly shorter and FSH starts to rise and vary. Many women in their late 30s and early 40s are in this stage without knowing it.
Early menopausal transition: the first stage of perimenopause
The early transition, Stage −2, begins when cycle length becomes variable: a difference of 7 days or more between consecutive cycles, happening again within 10 cycles. FSH is raised but variable, and AMH is low. This stage varies a lot in length. Periods may also get heavier or lighter, and the first sleep problems, mood changes and hot flashes can appear.
Late menopausal transition: skipped periods
The late transition, Stage −1, starts with a gap of 60 days or more without a period. Cycle length varies widely, hormone levels swing to extremes, and many cycles don't release an egg. FSH is often above 25 IU/L on a random blood test. This stage lasts 1 to 3 years on average, and hot flashes are most likely to occur during it.
The final menstrual period: the menopause stage
Stage 0 is the final menstrual period itself. You can only identify it looking back, after 12 months without bleeding. That 12-month point is what's commonly called menopause. The median age at the final period was 51.4 in SWAN, and it usually falls between 45 and 55. After that point, you are postmenopausal, and any bleeding needs checking. On hormonal contraception or HRT with monthly bleeds, the final period can be hidden, so age and symptoms guide the call.
Early postmenopause: hormones settle
Early postmenopause has three substages. Stage +1a is the first year after the final period, the end of the 12 months that confirm menopause and the end of perimenopause. Stage +1b is the second year, when FSH keeps rising and estradiol keeps falling; hot flashes are most likely in these 2 years. Stage +1c, lasting 3 to 6 years, is when hormone levels stabilize. The whole early postmenopause lasts about 5 to 8 years.
Late postmenopause: the final stage
Stage +2, late postmenopause, is the rest of life after hormone levels have settled. In this stage, changes linked to aging become more important than hormonal ones. Vaginal and urinary symptoms of the genitourinary syndrome of menopause often become more noticeable and tend to persist without treatment, and bone density keeps falling. Treating these symptoms, and protecting bones and heart, matters more in this stage than hot flashes, which have usually faded.
Menopause stages after a hysterectomy or on contraception
Women who have had a hysterectomy or endometrial ablation cannot be staged by their periods, so STRAW+10 relies on supporting criteria such as hormone levels instead. Hormonal contraception causes the same problem: the combined pill gives regular withdrawal bleeds, and progestogen-only methods can stop periods. In these cases, symptoms such as hot flashes, and your age, are the practical guides, and a doctor can sometimes use a blood test to help.

Video: Perimenopause, explained: what's happening, how long it lasts, and what helps
Read the transcript (826 words)▾
Day one. I found my keys in the fridge. Day four, three a.m., soaked. Day nine, my heart took off at my desk. I thought I was falling apart.
She wasn't. She was in perimenopause, and almost nobody had explained it to her. Let's fix that. Six minutes: what it is, what it feels like, how long it lasts, how it's diagnosed, and what helps.
Perimenopause is the transition to menopause. Menopause itself is a single point: twelve months after your last period. Everything before it, the years when your hormones start to change, is perimenopause.
Most people picture estrogen sliding down a gentle slope. In perimenopause it doesn't slide. It swings. Some months it drops, some months it spikes higher than it did in your thirties, while progesterone tends to fall. That rollercoaster, not a slow decline, is behind a lot of what women feel.
For most women, menopause arrives between forty-five and fifty-five. Perimenopause starts years before that, often in the early or mid forties.
Doctors describe it in stages. In the early transition, the length of your cycle keeps changing by seven days or more from one month to the next. In the late transition, you go sixty days or more without a period, and that stage usually lasts one to three years.
Hot flashes are the famous one. Between fifty and seventy-five percent of women get hot flashes or night sweats during the transition. They're far from the only one.
Across sixteen studies, seventy-one percent of women in perimenopause reported joint or muscle pain.
In SWAN, the large American study that followed women through the transition, about half had a moderate or high chance of palpitations during perimenopause.
Women with no history of depression were more than four times as likely to have high depressive symptom scores during the transition as before it.
And memory: in SWAN, women learned new information less well during perimenopause, then bounced back after menopause.
Add broken sleep, itchy skin, a dry mouth, rage over a spoon. Each one gets blamed on stress, age or a busy life. Put them side by side, and a pattern appears.
The other side matters too. In SWAN, about one in five women started out with almost no symptoms. There is no single normal.
This is the part women are rarely told. In SWAN, frequent hot flashes lasted a median of seven point four years in total, and went on for a median of four and a half years after the final period.
Women whose hot flashes started early, while periods were still regular or just beginning to change, had the longest course: a median of more than eleven point eight years. African American women had a median of ten point one years.
So "it'll pass in a few months" is, for many women, simply not true. That's exactly why waiting it out shouldn't be the only plan.
Here's what surprises people. For women forty-five and over, UK guidelines say perimenopause can be identified from your symptoms and your cycle changes, without a blood test.
That's because hormone levels swing from day to day in the transition. A normal FSH result one week says little about the next.
There are exceptions. Under forty-five, and especially under forty, a doctor may use blood tests to look for other causes, including premature ovarian insufficiency. And because about one in eight women develops a thyroid problem, which can look a lot like perimenopause, a simple TSH test is often worth doing.
The most useful thing you can bring to an appointment is a record: your cycle dates, your main symptoms, and when they happen.
For hot flashes and night sweats, hormone therapy is the most effective option. Estrogen cuts how often hot flashes happen by about seventy-five percent. For healthy women under sixty, or within ten years of their last period, the Menopause Society finds the benefits generally outweigh the risks.
If hormones aren't right for you, there are non-hormonal medicines. Fezolinetant works directly on the brain's thermostat. Certain antidepressants, in low doses, reduce hot flashes by roughly forty to sixty-five percent.
For sleep, cognitive behavioral therapy for insomnia has strong evidence. In a trial of women with hot flashes, eighty-four percent were in the no-insomnia range six months later, compared with forty-three percent who got education alone.
None of this means everyone needs medicine. It means there are options, and they're worth a real conversation with your doctor.
A few things need a doctor soon, whatever your stage. Any bleeding twelve months or more after your last period. Palpitations with chest pain, breathlessness or fainting: that's an emergency, call 911. And periods that stop or turn irregular before forty.
Mae's turning point wasn't a test. It was someone finally putting her symptoms side by side. You can start that today. Find your stage in two minutes at perimenostage.com, and take what you learn to your doctor.
Nobody had told me. Now somebody has.

Stages of menopause: questions women ask
What are the 7 stages of menopause?
The 7 stages are a popular idea, not a medical model. The medical standard, STRAW+10, uses these stages: late reproductive (−3), early transition (−2), late transition (−1), the final period (0), early postmenopause (+1) and late postmenopause (+2). Some of these are split into substages.
Are there really seven stages of menopause?
No. The seven stages come from popular articles, not medical research. Doctors and researchers use STRAW+10, which describes the late reproductive stage, the early and late menopausal transition, the final period, and early and late postmenopause, with some stages split into substages. Everyday speech simplifies this to perimenopause, menopause and postmenopause.
What are the 3 stages of menopause?
In everyday terms: perimenopause, when periods become irregular; menopause, the point 12 months after your last period; and postmenopause, the years after. These map onto the STRAW+10 transition stages, the final period and the postmenopause stages.
What are the beginning stages of menopause?
The late reproductive stage, when cycles may get slightly shorter, followed by the early transition, when cycle length varies by 7 days or more. The first hot flashes, sleep problems and mood changes often appear here.
How do I know which stage of menopause I'm in?
Look at your periods. Regular cycles mean you're still in the reproductive stages. Cycles varying by 7 days or more mean early transition. Gaps of 60 days or more mean late transition. 12 months with no period means you've reached menopause. Our 2-minute check uses these markers.
Related →Which stage of menopause has the worst symptoms?
For many women, the late transition and the first 2 years after the final period, when hormones change fastest and hot flashes are most likely. Vaginal and urinary symptoms tend to be worst later, in postmenopause, if untreated.
How long does each stage of menopause last?
The early transition varies a lot. The late transition lasts 1 to 3 years on average. The first 2 years after the final period are the most hormonally active, and early postmenopause lasts about 5 to 8 years in total. Late postmenopause is the rest of life.
Related →Can hormone tests tell me my stage?
They can support it, but your bleeding pattern is the main marker. In the late transition, FSH above 25 IU/L on a random test is typical, but levels swing. NICE advises against using FSH tests to diagnose perimenopause in women 45 and over.
Is perimenopause a stage of menopause?
Yes. In STRAW+10, perimenopause covers the early and late menopausal transition and the first 12 months after the final period. It is the stage most women mean when they say they are going through menopause, and it is when most symptoms start.
What stage is postmenopause?
Postmenopause starts after the 12 months without a period that confirm menopause. STRAW+10 splits it into early postmenopause, about 5 to 8 years in which hormone levels settle, and late postmenopause, the rest of life. Bleeding at any point in postmenopause needs checking.
