When Does Menopause Start? Age, Stages and Timing

Menopause is being talked about more than ever, but many women still find themselves in the middle of perimenopause without realizing it has already begun. So, when does menopause actually start?

If you have noticed changes in your body and wondering whether menopause might be starting, welcome to the club.

Your menopause journey happens in three stages: perimenopause, menopause, and postmenopause.¹ Each stage brings different changes, and your menopause timeline is unique – not everyone experiences menopause in the same way.^1,2

Knowing roughly what to expect and what may affect your timeline could help spot changes earlier, feel more prepared, and find support when you need it.

What Exactly Is Menopause?

But, what is menopause exactly? It might be confusing, but menopause is a single, defined moment.¹

There is a stage before (perimenopause) and a stage after (post menopause).¹

When people say a woman is 'going through menopause' what they actually may be describing is perimenopause.²

This refers to years of change leading up to that single point of periods stopping, and the years after, are postmenopause.¹

Menopause is not a medical problem, but it does come with changes that deserve your attention (and maybe some preparation).¹

Why Does Menopause Happen?

You’re born with a limited number of eggs in your ovaries.^{3, 4} As you go through each monthly cycle, your egg stores get smaller because of ovulation.⁵

Eventually, the store gets small enough to trigger your ovaries to make less estrogen and progesterone.⁵

Your brain responds to these lower levels of estrogen by making more follicle-stimulating hormones (FSH) to encourage your ovaries to release more eggs.⁵

In the moment, it works, but over time, your ovaries could stop responding, and your estrogen levels fall, causing menopausal symptoms.^4,5

Sometimes you might notice lesser-known symptoms of menopause. It might be surprising, but it happens because estrogen affects many parts of your body, including your brain, heart, bones, and bladder.⁴

What Are the Three Stages of Menopause?

Let’s look at what you could expect in each stage.

Perimenopause: The Transition Phase

Perimenopause, menopause, and postmenopause each bring their own changes and symptoms.¹

Let’s break down what you can expect in each phase, so you’re ready for a deeper dive into the specifics later on.

What Age Does Perimenopause Typically Begin?

Before you experience menopause, perimenopause comes first.² It is a transition period where your hormones, estrogen and progesterone, fluctuate and decline.⁶

Because of these hormonal changes, you might notice your ovulation dates become unpredictable, and your periods can change in length, frequency, and flow.^5,6

Even though your period pattern changes, you might still need contraception, as you may be able to get pregnant.⁷

Perimenopause could start in your mid to late 40s, although some women notice changes in their 30s already.^2,8 On average, most women begin this stage around 47 years, and it could last anywhere from 4 to 10 years.^7,8

During the final 1 to 2 years, estrogen levels may decline more noticeably, affecting organs like your urethra and bladder.^8,9

Some symptoms you might notice during this time include:

• Hot flushes⁷
• Night sweats⁷
• Trouble sleeping⁷
• Mood swings⁷
• Brain fog⁷
• Irregular periods⁷
• Vaginal dryness⁷
• Low sex drive⁷
• Bladder leaks when you cough or sneeze⁷
• Urgency⁹
• More bathroom breaks than usual⁹

Menopause: The Defining Moment

It might feel confusing, but even if your symptoms feel intense, menopause has not happened until you have gone 12 consecutive months without a period or spotting.³

The average age for women in US is 52 years, but most women notice this point between 45 and 55 years.3 Also, you might still notice some perimenopause symptoms 1 to 2 years after this point.¹⁰

What Is the Average Age for Menopause?

Most women go through menopause around age 52.¹ That said, the timing can vary, and some women might experience menopause a bit earlier or later. Looking at your family history can give you an idea of when you might expect to go through menopause.²

Postmenopause: Life After Menopause

Postmenopause begins after you have gone 12 full months without a period.1 It starts immediately after menopause and continues for the rest of your life.¹

During this stage, estrogen levels stay at a lower, more stable level.11For some women, symptoms such as hot flushes and night sweats may begin to ease over time.11 For others, these symptoms could continue into their 60s.¹²

Some changes from low estrogen may also continue and need your attention during postmenopause, for example: vaginal dryness and bladder issues.11, ¹³

Postmenopause is not simply the end of menopause symptoms, but a new stage of long-term health.11 During this time, lower estrogen levels may affect bone and heart health over time.¹¹

Speaking with your doctor about long-term health checks, including bone density, cholesterol, and cardiovascular health, could help you stay understand what going on.

What Factors Can Influence Early or Late Menopause?

Your menopause age range often depends on your genetics.⁷ But sometimes, there are other factors that could shift your menopause timeline earlier or later.

Factors That Can Bring Menopause Earlier

Genetics and family history: The age your mother reaches menopause, might play a big role in your own menopause age.14 For example, if she experienced it earlier, you might have a similar onset.¹⁴

Smoking: The chemicals in cigarettes could reduce how many eggs you have in your supply, causing menopause to come 1 to 2 years earlier.^14,15

Chemotherapy and pelvic radiation: These cancer treatments could affect your ovaries, triggering early menopause symptoms.16 These symptoms may be temporary or permanent depending on the treatment you had, and age.¹

Surgical removal of the ovaries (oophorectomy): This type of surgery may cause immediate surgical menopause, regardless of your age.¹⁶

You might notice symptoms differently from natural menopause because your estrogen levels drop suddenly, rather than gradually over time.^16,17

Autoimmune conditions: Conditions such as thyroid disease or rheumatoid arthritis could trigger early menopause.¹⁴

Low body weight: Your body fat also plays a small role in estrogen production.18 That’s why women with very low body fat might notice menopause happening earlier than others.¹⁴

Factors Associated with Later Menopause

Genetics: Just like in early menopause, if it tends to happen later in your family, you may also notice it starting later for you.¹⁴

Higher number of pregnancies: Women who have had one or more pregnancies may experience menopause later on.19 It might happen because pregnancy temporarily pauses ovulation.¹⁹

Ethnicity: Your ethnicity may affect the age when menopause begins.20 Japanese and White women may experience menopause later on, while Hispanic and Black women may experience it earlier.²⁰

What Is Premature Menopause?

They may feel similar, but early menopause and premature ovarian insufficiency (POI) are different.

POI happens when the ovaries stop working properly before the age of 40, causing irregular or absent periods, but you could still get pregnant.²¹

Early menopause, on the other hand, means menopause happens earlier than usual, between the ages of 40 and 45.²¹

POI is less common than early menopause. It affects around 1 in 100 women under 40, while early menopause affects about 5% of women.^22,23

Sometimes the cause of POI or early menopause may be unknown, but other factors that could increase the risk. They include:^14,21,22

• Genetics, such as chromosomal conditions (like Turner syndrome)²¹
• Autoimmune conditions, such as thyroiditis²¹
• Medical treatments such as chemotherapy, radiation, or surgery²¹

If you notice signs of menopause before 40, it’s a good idea to see your doctor, because POI could expose you to a long period of low estrogen levels, affecting your bone, heart, and brain health.^21,22

Your doctor might order blood tests to check your FSH levels four weeks apart, among others, to help rule out POI.^21,24

If you have POI, your doctor might suggest hormone replacement to help with symptoms at least until you reach the natural age of menopause.^21,22

How Long Does Menopause Last?

Like we’ve mentioned before, the menopausal timeline has three stages: perimenopause, menopause, and postmenopause.¹

Perimenopause lasts for 4 to 10 years, although for some women, it may be shorter.⁹ Many women notice more symptoms during the final 1 to 2 years, when estrogen levels tend to be more noticeable.⁸

Menopause itself is a single moment in time.¹ At this stage, you have gone 12 consecutive months without a period.¹ After this point, postmenopause begins and continues for the rest of your life.¹

When it comes to menopausal symptoms, some women may notice symptoms such as hot flushes for 7 to 10 years, while for others, symptoms may last for a much shorter time.²⁵

Vaginal dryness and bladder changes may also continue into postmenopause and could worsen without treatment.^11,13

So, when do women experience menopause?

Your timeline and experience is unique, and there’s no set time that menopause can start, only a guide, like the one we’ve given you here to help you identify and manage symptoms as they arrive, and talk to a doctor when needed.
