How Long Does Menopause Last? Stages, Timelines and What Changes the Length

A reader wrote to us in January with a question that sounded almost like an apology: “My last period was six years ago. Why am I still waking up soaked at 3 a.m.?” She had been told, by a well-meaning relative, that menopause “takes about a year.” Nobody had told her that the year is the definition, not the experience.

Her question is suddenly everyone’s question. Late 2025 brought two developments that pushed menopause back into the headlines: a second non-hormonal prescription medicine for hot flashes received US approval in October, and in November the US Food and Drug Administration announced it would remove the long-standing boxed warning from systemic hormone therapy labels. As of early 2026, searches for how long does menopause last have climbed alongside those stories, often tangled with viral claims that it “lasts forever” or “ends at 55.”

Neither is true. The real answer has stages, a median, a wide range and a short list of things that stretch or shorten it. Here is what the evidence shows, and how strong that evidence is.

What changed recently: why menopause length is a hot search again

Three dated events explain the current spike in interest, and none of them changes the biology of the transition. They change the conversation around it.

In May 2023, the US Food and Drug Administration approved fezolinetant (brand name Veozah), the first medicine in a class called neurokinin 3 receptor antagonists. A neurokinin 3 receptor antagonist is a drug that calms the brain cells in the hypothalamus that trigger hot flashes once estrogen falls. In October 2025, a second medicine in a related class, elinzanetant (brand name Lynkuet), received US approval for moderate to severe hot flashes and night sweats. For the first time, people who cannot or prefer not to use hormones have more than one prescription option designed specifically for the symptom that most often outlasts the transition.

Then, in November 2025, the FDA announced it would remove the boxed warning that had sat on systemic menopausal hormone therapy labels since 2003. The agency framed the change as an update to reflect two decades of follow-up data on timing, age and formulation. Professional societies had already moved toward individualized, age-aware prescribing; the label change brought packaging closer to that practice.

Why does this matter for the question of duration? Because the length of menopause was, for many years, discussed as something to simply wait out. The National Institute on Aging and Mayo Clinic now describe the transition as a multi-year phase with symptoms that can be managed at any point, not only in the first twelve months. The newest approvals reinforce that framing. They do not promise a shorter transition, and no clinician should tell you otherwise; they widen the set of conversations worth having with a doctor if the years are stretching on.

How long does menopause last? The honest short answer

Start with the definition, because it is the source of most confusion. Menopause is diagnosed retrospectively: it is the day you have gone twelve consecutive months without a menstrual period, with no other cause such as pregnancy, breastfeeding, a medicine or illness. On that definition, menopause lasts one day. Everything before it is perimenopause; everything after it is postmenopause, which lasts the rest of your life.

What people actually mean when they ask how long does menopause last is: how long will I feel like this? That has a measurable answer, and it is longer than most families pass down.

Perimenopause, the stretch of irregular cycles and fluctuating hormones before the final period, lasts about four years on average according to Cleveland Clinic and the National Institute on Aging, with a documented range from a few months to roughly ten years. Vasomotor symptoms, the medical term for hot flashes and night sweats, were tracked in the largest US cohort of midlife women, the Study of Women’s Health Across the Nation (SWAN). Among women who experienced them frequently, the median total duration was 7.4 years, and the median persistence after the final period was 4.5 years. One in ten women in NHS guidance reports symptoms lasting up to twelve years.

Put those together and a realistic expectation for a person with typical symptoms is somewhere between five and ten years of noticeable change, centered on the final period rather than ending there. Some people move through it in two years. Others need fourteen. Both are within the normal distribution, which is exactly why a single number has never served readers well.

What are the different stages of menopause?

Clinicians use a framework called STRAW+10, published in 2012, which stands for Stages of Reproductive Aging Workshop. It divides adult reproductive life into stages based on cycle patterns and hormone measurements rather than age alone. For everyday use, three phases matter.

Perimenopause begins when cycles start to vary. STRAW+10 marks the early phase as a persistent change of seven days or more in cycle length between consecutive cycles. The late phase is defined by gaps of sixty days or longer between periods. During both, the ovaries release estradiol (the main form of estrogen) erratically, swinging high and low within the same month, while follicle-stimulating hormone (FSH), the pituitary signal that tells the ovaries to work harder, climbs. Those swings, not a steady decline, are what produce the characteristic unpredictability of hot flashes, sleep disruption and mood changes.

Menopause is the single anniversary point described above. Doctors do not typically need a blood test to confirm it in someone over 45 with a classic pattern; the calendar is the test.

Postmenopause is subdivided by STRAW+10 into early (the first several years, when hormone levels settle and symptom frequency peaks then recedes) and late (the long stable phase, when concerns shift toward bone, heart and genitourinary tissue health).

Two things about the stages of menopause trip people up. First, you can be in late perimenopause and still conceive; contraception guidance from the NHS advises continuing until twelve months after the last period if you are over 50, and two years if under 50. Second, surgical removal of both ovaries skips the stages entirely and produces abrupt menopause, which is one reason the experience can be more intense.

How long does perimenopause last, and when does it start?

Perimenopause most often begins in the mid-40s. Mayo Clinic places the usual onset between 40 and 44, with the National Institute on Aging noting that for most people it starts in the 45 to 55 window and lasts about seven years in total when early and late phases are combined, though many sources quote a four-year average for the symptomatic part.

Why the spread? Because “start” is hard to pin down. The first changes are often subtle: a cycle that arrives three days early, slightly heavier flow, a night of unexplained sweating. Many people date their perimenopause to the first obvious hot flash, which can be years after the hormonal shift actually began. SWAN data suggest sleep disturbance and mood changes frequently precede hot flashes.

The length also depends on the measuring stick. Using the STRAW+10 definition (persistent cycle irregularity to final period), the median is around four years. Counting from the first symptom to the last, it can reach a decade. Cleveland Clinic gives the full range as a few months to ten years.

A handful of patterns from observational cohorts are worth knowing:

• People who start perimenopause earlier tend to have a longer transition, not a shorter one.
• Those whose hot flashes begin while they are still having periods report the longest total symptom duration, a median of nearly twelve years in SWAN.
• Cycle gaps of sixty days or more usually signal that the final period is within one to three years.

This is observational evidence, strong enough to set expectations but not to predict any individual’s calendar. If you want a working rule: once periods become unpredictable, plan for several years of change, and treat anything shorter as good fortune rather than the norm.

What is the average age for menopause?

In the United States, the average age at the final menstrual period is 51, according to Mayo Clinic, the National Institute on Aging and MedlinePlus. The NHS gives 51 for the UK as well. Most people reach it between 45 and 55; that ten-year window captures the large majority of natural menopause.

Averages hide meaningful variation. Roughly 5 percent of women reach menopause between 40 and 45, which is classified as early menopause. About 1 percent reach it before 40, classified as premature menopause or primary ovarian insufficiency (the loss of normal ovarian function before 40). At the other end, a small proportion continue menstruating into their late 50s, and that is still within normal limits.

Several factors nudge the average age, and the evidence quality varies:

• Genetics carries the most weight. Your mother’s or sister’s age at menopause is the single best non-medical predictor of your own, a finding replicated across population studies.
• Smoking is associated with menopause one to two years earlier on average, with a dose-response pattern. This is consistent observational evidence, not a trial, but it is one of the most robust lifestyle associations in the field.
• Surgery and treatment. Removal of both ovaries causes immediate menopause. Chemotherapy and pelvic radiation can bring it forward or cause it outright, depending on age and regimen. A hysterectomy that leaves the ovaries in place does not cause menopause but can advance it by a year or two.
• Ethnicity and geography show small average differences in large cohorts, though socioeconomic and smoking patterns explain part of the gap.

Age matters for duration because it anchors the whole timeline: the earlier the transition starts, the longer, on average, symptoms persist, and the more years of postmenopause lie ahead.

How long do hot flashes last after your last period?

Hot flashes are the symptom most people are really asking about, and here the evidence is unusually good. SWAN followed more than 1,400 women with frequent vasomotor symptoms across seven US sites for up to seventeen years, with results published in JAMA Internal Medicine in 2015. Because it tracked people prospectively rather than asking them to remember, it is the best available answer to how long do hot flashes last.

The headline figures:

• Median total duration: 7.4 years.
• Median duration after the final menstrual period: 4.5 years.
• Women whose hot flashes started in early perimenopause: median 11.8 years total.
• Women whose hot flashes started only after the final period: median 3.4 years.

In other words, an early start predicts a long run. That finding reversed an older assumption that early symptoms meant you would “get it over with” sooner.

Duration also varied by self-identified ethnicity in the cohort: a median of about 10 years for Black women, 9 for Hispanic women, 6.5 for non-Hispanic white women, and roughly 5 for Chinese and Japanese American women. Researchers attribute part of this to differences in body composition, stress, smoking and access to care rather than biology alone, and the gaps narrowed once those were accounted for.

Other factors associated with longer hot flash duration in SWAN included higher perceived stress, more depressive and anxiety symptoms at onset, lower education level and younger age at first symptom. None of these is destiny. Hot flashes also follow a curve rather than a plateau: for most people, frequency peaks around the final period and in the first year or two after it, then declines gradually. A small minority, under 10 percent in most surveys, still report occasional hot flashes in their 70s. That is uncommon but documented, and it does not signal anything wrong.

Menopause timeline at a glance: typical ranges and what shifts them

Readers have asked for the numbers in one place, so here they are. Every figure below comes from the sources cited at the end of this article, and the “what shifts it” column reflects observational associations rather than guaranteed effects. Medians describe the middle person; half of people fall on either side.

Phase or symptom	Typical duration or timing	Documented range	What tends to shift it
Perimenopause	About 4 years (symptomatic phase); up to 7 years counting early changes	A few months to 10 years	Earlier onset lengthens it; smoking shortens time to final period
Age at final period	51 (US and UK average)	Normally 45 to 55	Family history, smoking, ovarian surgery, chemotherapy
Hot flashes, total	Median 7.4 years	Under 2 years to more than 14	Start before final period lengthens; higher stress and BMI associated with longer
Hot flashes after final period	Median 4.5 years	Months to 12+ years	Late-onset flashes resolve faster (median 3.4 years)
Sleep and mood changes	Peak in late perimenopause and early postmenopause	Variable; often improve within 2 to 5 years after final period	Night sweats, prior depression history, life stressors
Vaginal and urinary symptoms	Begin in late perimenopause or after	Persist indefinitely without treatment	Do not resolve on their own; local treatments are available via a clinician
Rapid bone loss	Fastest in the first 5 to 7 years after final period	Slows but continues afterward	Earlier menopause means more years of lower estrogen

Two patterns stand out. First, the phases overlap rather than queue up neatly; it is normal to have sleep disruption, hot flashes and cycle changes at once. Second, not every symptom has an end date. Hot flashes and sleep changes trend toward resolution. Genitourinary changes trend the other way, which is why they deserve a separate conversation with a doctor rather than patience.

What changes the length of menopause: genetics, smoking, weight and more

Why does one person finish in two years and a neighbor need twelve? Observational research points to a consistent set of modifiers. The evidence here is association, not proof of cause, but the patterns repeat across cohorts on three continents.

Age at onset. The most reliable predictor. Symptoms that begin while cycles are still regular run roughly three times longer than symptoms that begin after the final period. The biology is intuitive: an early start means more years of hormonal fluctuation before levels settle.

Family history. Timing clusters in families, and so, to a lesser degree, does symptom pattern. Twin studies estimate that about half the variation in age at menopause is heritable.

Smoking. Current smokers reach menopause earlier and, in several cohorts, report more severe and longer-lasting hot flashes. The likely mechanism involves accelerated follicle loss and effects on estrogen metabolism.

Body weight. The relationship is not simple. Fat tissue produces a weak estrogen, which once led to a theory that higher weight would mean fewer hot flashes. SWAN and other studies found the reverse during perimenopause: higher body mass index was associated with more frequent and longer-lasting vasomotor symptoms, possibly because fat tissue insulates and hampers heat loss.

Mood and stress. Depressive symptoms, anxiety and high perceived stress at the start of the transition predicted longer symptom duration in SWAN. The direction of cause is unclear; poor sleep from night sweats can itself worsen mood.

Medical interventions. Surgical menopause tends to produce more abrupt and intense symptoms. Cancer treatments vary widely in effect.

What this list does not include is anything you did wrong. Length is largely set by timing and inheritance. Where modifiable factors appear, the strongest is smoking, and the benefit of stopping extends well beyond the menopause timeline.

Early menopause and primary ovarian insufficiency: when the timeline starts before 45

Around one in twenty women reach their final period between 40 and 45, and about one in a hundred do so before 40. The terminology matters because it signals different follow-up. Menopause between 40 and 45 is called early menopause. Loss of normal ovarian function before 40 is called primary ovarian insufficiency (POI), a term clinicians now prefer to “premature menopause” because, unlike menopause, ovarian function in POI can be intermittent and spontaneous ovulation occasionally occurs.

Causes include genetic conditions such as Turner syndrome or fragile X premutation, autoimmune disease, chemotherapy, pelvic radiation and surgical removal of the ovaries. In many cases, no cause is found.

Why does early timing change the conversation about duration? Three reasons:

• More years of low estrogen. Bone density and cardiovascular protection depend partly on estrogen exposure across the lifespan. The NHS and the National Institute on Aging note that people with early menopause or POI face higher long-term risk of osteoporosis and heart disease than those who reach menopause at the average age.
• A longer symptomatic stretch. Earlier onset is associated with longer symptom duration, and symptoms after surgical menopause can be more abrupt.
• Different treatment framing. For POI, UK and US guidance generally regards hormone replacement until at least the average age of natural menopause as replacement of a missing hormone rather than optional symptom relief, unless there is a specific reason not to. That decision, including what and how, belongs entirely to the treating clinician.

Diagnosis before 45 typically involves blood tests, usually FSH measured on two occasions several weeks apart, along with evaluation for underlying causes. This is one of the clearest situations in which “wait and see” is the wrong approach: if periods stop or become very infrequent before 45, a medical evaluation is warranted.

What happens after menopause ends? Postmenopause explained

Postmenopause is the longest phase and, statistically, a third of life. A person who reaches menopause at 51 and lives to the US average female life expectancy spends roughly thirty years in it. So what happens after menopause in practical terms?

Symptoms recede, unevenly. Hot flashes decline over the first several years for most people. Sleep often improves as night sweats fade. Mood symptoms tied to hormonal fluctuation tend to ease once levels stabilize, though depression with other causes does not simply lift.

Some changes persist or progress. Genitourinary syndrome of menopause, the umbrella term for vaginal dryness, irritation, pain with sex, urinary urgency and recurrent urinary infections caused by low estrogen in those tissues, affects an estimated half of postmenopausal women and does not improve on its own. Hair, skin and joint changes are common and gradual.

Risk profiles shift. Bone loss accelerates in the five to seven years after the final period; the National Institute on Aging notes that women can lose up to 20 percent of bone density in that window. Cardiovascular risk rises to approach that of men of the same age within a decade or so, which the American Heart Association attributes to loss of estrogen’s effects on blood vessels and cholesterol, alongside aging itself.

Screening continues. Cervical screening, breast screening and, from the age recommended in national guidance, bone density assessment are part of routine postmenopausal care. The schedules depend on age and risk factors, so follow your clinician’s advice rather than a general article.

One hard rule stands out: any vaginal bleeding after twelve months without a period is not a late period and not “menopause coming back.” It is a symptom that always needs prompt medical evaluation, even if it is light, even if it happens once.

What is the average weight gain during menopause, and is it the hormones?

The honest answer is that midlife weight gain is real, modest and only partly hormonal. Mayo Clinic cites studies showing women gain, on average, about 1.5 pounds per year through their 40s and 50s. Across a decade that is roughly 15 pounds, and most of it is not caused by menopause itself. Aging reduces muscle mass, which lowers resting energy use; sleep disruption and shifting activity patterns do the rest.

What menopause does change, with reasonably strong observational support, is where weight settles. As estrogen falls, fat distribution shifts from hips and thighs toward the abdomen. SWAN measured this directly: waist circumference and visceral fat increased around the final period even in women whose total weight stayed stable. Visceral fat, the kind packed around internal organs, is metabolically more active and more strongly linked to cardiovascular and metabolic risk than fat under the skin.

A few evidence-based points to keep this in proportion:

• Randomized trials of menopausal hormone therapy have not shown it to cause weight gain; some suggest it slightly limits abdominal fat accumulation. Weight is not, on its own, a reason to start or avoid hormone therapy, and that decision rests with a prescriber.
• Resistance training two or three times a week preserves muscle and is the single most consistently supported strategy for limiting midlife fat gain.
• Protein intake and sleep quality matter more in this decade than in earlier ones because both counter muscle loss.

None of this is a moral failing or a reason to pursue extreme dieting, which accelerates muscle loss and backfires. The practical goal is maintaining strength and waist circumference rather than chasing a number from age 30. If weight is changing rapidly, especially with fatigue, hair changes or palpitations, thyroid function should be checked; thyroid disorders are common in the same age window and mimic menopausal symptoms.

What the evidence actually says about menopause duration, and how strong it is

Not all numbers in this article carry equal weight. Here is how the main claims grade on the standard hierarchy, from randomized trials at the top through prospective observational cohorts to expert consensus.

Strongest: prospective observational cohorts. The duration figures for hot flashes (median 7.4 years total, 4.5 years after the final period) come from SWAN, a multi-ethnic cohort followed for up to seventeen years with repeated in-person visits. Similar durations appear in the Penn Ovarian Aging Study and the Melbourne Women’s Midlife Health Project. For a question about natural history, this is the best design available; you cannot randomize people to menopause. Confidence: high for the population medians, moderate for subgroup differences.

Moderate: cross-sectional and registry data. Average age at menopause (51) and the proportion with early menopause (about 5 percent) rest on large population surveys across many countries. Consistent, but less precise about individual trajectories.

Moderate to lower: modifiers. Associations between duration and smoking, body mass index, stress and ethnicity are reproducible but observational. They may reflect confounding, and they describe averages that cannot forecast any one person’s timeline.

Expert consensus: the stage definitions. STRAW+10 criteria are consensus-based, built on cohort data but ultimately agreed by a panel. They are useful clinical shorthand rather than biological boundaries.

Randomized trial evidence exists for treatments, not for duration. Menopausal hormone therapy, fezolinetant and elinzanetant have each been shown in randomized, placebo-controlled trials to reduce hot flash frequency and severity while taken. No trial shows that any treatment shortens the underlying transition; symptoms commonly return if a medicine is stopped during the symptomatic years. Whether, when and how to use any of these is a decision for the prescribing clinician, weighing age, time since final period, personal and family history and preference.

The gap in the literature is men and women outside high-income countries, and people whose symptoms are mild and never studied. The medians above describe people with frequent symptoms, so they likely overstate duration for the population as a whole.

Common myths about how long menopause lasts

Several claims circulating on video platforms this year deserve a direct correction.

“Menopause lasts about a year.” The twelve-month rule defines the diagnosis, not the experience. Symptoms typically span several years on either side of that anniversary.

“It never ends.” Postmenopause is lifelong, but the symptomatic phase is not. Hot flashes resolve for the large majority within about a decade of the final period, and most people in their 60s report few or none. The symptoms that persist, mainly genitourinary, are treatable through a clinician and not a sign that “menopause” is ongoing.

“If your hot flashes start early, you’ll be done early.” SWAN found the opposite: early onset predicted the longest total duration, nearly twelve years at the median.

“Hormone therapy just delays the inevitable.” Hormone therapy manages symptoms while it is taken; it neither extends nor shortens the biological transition. Symptoms may return after stopping if a person is still within the symptomatic years, which is different from the treatment having prolonged anything. Timing of use is an individual medical decision.

“A blood test tells you how long you have left.” FSH and estradiol swing widely during perimenopause; a single reading can look postmenopausal one month and premenopausal the next. The NHS advises that over 45, diagnosis rests on symptoms and cycle pattern, not labs. Anti-Müllerian hormone, a marker of ovarian reserve, correlates with time to final period at a population level but is not accurate enough to give an individual a date.

“Menopause ends at 55 for everyone.” Fifty-five is the upper edge of the usual window for the final period, not an expiry date for symptoms. A person whose final period arrives at 54 may reasonably expect changes well past 58.

“Supplements can shorten it.” No supplement has been shown in trials to alter the length of the transition. Several have modest, mixed evidence for symptom relief; none changes the calendar.

When to see a doctor about menopause symptoms or timing

Most of the menopause transition can be navigated with information and, where wanted, treatment chosen with a clinician. Some situations call for an appointment promptly rather than at the next routine visit. The NHS, Mayo Clinic and MedlinePlus agree on the core list.

Seek medical advice soon if you notice:

• Any vaginal bleeding after twelve consecutive months without a period, however light or brief.
• Periods during perimenopause that are very heavy (soaking through protection hourly), last longer than seven days, occur more often than every three weeks, or include large clots.
• Bleeding after sex at any stage.
• Periods stopping or becoming very infrequent before age 45, or any menopausal symptoms before 40.
• A new breast lump, nipple discharge or skin change on the breast.
• Persistent low mood, loss of interest, anxiety that interferes with daily life, or any thoughts of self-harm. Mood changes are common in the transition; severe or persistent ones are not something to wait out.
• Palpitations, chest pain, breathlessness or fainting. Palpitations can accompany hot flashes but also signal heart rhythm or thyroid problems and need evaluation.
• Pain with urination, blood in urine or recurrent urinary infections.
• Hot flashes, night sweats or sleep disruption severe enough to affect work, relationships or safety.

Call emergency services for chest pain with sweating or arm or jaw pain, sudden severe headache, sudden weakness or confusion, or heavy bleeding with dizziness.

When you do see a clinician, bring a record of your cycles and symptoms over the past few months; it is more useful than any single blood test. Be ready to discuss family history of breast cancer, blood clots, heart disease and osteoporosis, because those shape which treatments are appropriate. Every decision about starting, continuing, changing or stopping a medicine, including hormone therapy and the newer non-hormonal options, belongs to you and your prescribing clinician together, informed by your individual history. Articles like this one can prepare the conversation; they cannot replace it.

Frequently asked questions

How long does menopause last on average?

For most people, noticeable symptoms span about five to ten years centered on the final period. Perimenopause averages roughly four years, and hot flashes last a median of about seven years in the largest US cohort, with around four and a half of those years after the last period. Menopause itself, defined as twelve months without a period, is a single point rather than a phase.

What is the average age for menopause?

The average age at the final menstrual period is 51 in the United States and the United Kingdom. Most people reach it between 45 and 55. About 5 percent reach menopause between 40 and 45, called early menopause, and about 1 percent before 40, called primary ovarian insufficiency. Family history is the strongest predictor of your own timing, followed by smoking.

What are the different stages of menopause?

There are three: perimenopause, menopause and postmenopause. Perimenopause is the years of irregular cycles and fluctuating hormones before the final period. Menopause is the point twelve months after that period. Postmenopause is everything afterward and lasts the rest of life. Clinicians subdivide these further using STRAW+10 criteria based on cycle gaps and hormone levels, but the three-phase model covers what most people need.

How long does perimenopause last?

About four years on average for the clearly symptomatic phase, with a range from a few months to roughly ten years. Counting from the earliest subtle cycle changes, the National Institute on Aging estimates around seven years. Once gaps between periods reach sixty days or more, the final period is usually within one to three years. People who start earlier tend to have longer transitions.

How long do hot flashes last after menopause?

A median of about 4.5 years after the final period, according to the SWAN study, though the range is wide. Hot flashes that begin only after the final period tend to resolve faster, with a median of 3.4 years. Those that start in early perimenopause run longest, nearly twelve years in total. A small minority of people still have occasional hot flashes in their 70s.

What happens after menopause ends?

Hot flashes, night sweats and sleep problems gradually fade for most people over several years as hormone levels stabilize. Vaginal dryness and urinary symptoms, by contrast, tend to persist or progress without treatment. Bone loss speeds up in the first five to seven years after the final period, and cardiovascular risk rises, which is why screening and heart-healthy habits take on greater weight in postmenopause.

What is the average weight gain during menopause?

About 1.5 pounds per year through the 40s and 50s, according to studies cited by Mayo Clinic, which adds up to roughly 15 pounds over a decade. Most of that comes from aging and loss of muscle rather than menopause itself. Falling estrogen does shift where fat settles, increasing abdominal and visceral fat even when total weight stays steady.

Can you still get pregnant during perimenopause?

Yes. Ovulation becomes irregular but does not stop until menopause, so pregnancy remains possible throughout perimenopause. NHS guidance advises continuing contraception until twelve months after the last period if you are over 50, and for two years after the last period if you are under 50. A clinician can advise on which methods suit this stage.

Does hormone therapy make menopause last longer?

No. Randomized trials show hormone therapy reduces hot flashes while it is taken; it does not alter the length of the underlying transition. If someone stops during the symptomatic years, symptoms may return because the transition is still underway, not because the treatment prolonged it. Whether to start, continue or stop hormone therapy is a decision for you and your prescribing clinician.

Can a blood test tell me how long until menopause?

Not reliably. FSH and estrogen levels swing widely during perimenopause, so a single reading can mislead. The NHS advises that for people over 45, diagnosis rests on symptoms and cycle pattern rather than blood tests. Anti-Müllerian hormone tracks ovarian reserve at a population level but cannot give an individual a date. Testing is more useful when symptoms begin before 45.
