"You Are Too Young for Menopause" — Why So Many Women in Their 40s Are Told This (And Why It Is Often Wrong)

You are 41. You have not slept properly in months. Your patience is shorter. Your joints ache. Your brain feels foggy in a way you cannot explain. You finally make a GP appointment, bring it up, and hear back: "You are too young for menopause."

Or some version of it. "Your periods are still regular, so it cannot be that." "Your bloods are fine, so it cannot be that." You go home. You feel a little less certain than when you arrived.

There are three sentences women in their 40s hear most often when they raise perimenopause symptoms, and none of them is an accurate reason to rule perimenopause out.

"You are too young"

The most quoted figure in menopause is that the median age in Australia is 51. The misunderstanding is what a median means. A median is a midpoint. Half of women will experience menopause before that age, and half after.

Symptoms of perimenopause typically begin earlier — the median age for the first signs is 47 (Study of Women's Health Across the Nation — SWAN; Australasian Menopause Society 2024). That means half of women begin to feel perimenopause symptoms before age 47.

Perimenopause itself can last anywhere from two to twelve years. Working backwards, that places the start of perimenopause for some women in their late 30s. It is not unheard of, but it is uncommon and warrants further investigation.

"Your periods are still regular"

This is the single biggest reason perimenopause is missed.

For many women, periods remain completely unchanged until they are well into perimenopause, or even near the end of it. (Newson 2023.) The textbook definition has historically been tied to cycle changes, but the clinical reality is that fluctuating hormones can drive symptoms long before the cycle itself shifts.

I am a Former Registered Nurse with years of clinical experience, yet I did not recognise my own perimenopause — because my periods were completely unchanged. That gap in my own knowledge is what sent me back to study.

"Your bloods are normal"

The current guidance from the Australasian Menopause Society, NICE in the UK, and the International Menopause Society is clear: for women over 45, perimenopause is a clinical diagnosis based on symptoms and age, not a blood test.

Hormone levels in perimenopause fluctuate constantly. You may get a "normal" blood test result, but that does not necessarily tell us the true picture. A snapshot taken on a single day cannot capture a moving target. A doctor should be able to make this diagnosis by listening to you — by hearing your symptoms, your history, and your age. Your symptoms and your age are the standard, not your blood test.

Did you know?

The fastest rate of bone loss in a woman's life happens in the two years before her final period — during perimenopause. Cardiovascular changes, lipid changes, and visceral fat gain also accelerate during perimenopause, not after. This is why leading menopause clinicians have shifted to treating symptoms when they appear rather than waiting for the transition to be complete. (Casperson & Smith 2025; SWAN cardiovascular cohort.)

What this means for you

If you are in your late 30s or 40s, your age does not rule out perimenopause. If your periods are still regular, that is not evidence against perimenopause. If your bloods are within range, that is not evidence against it either.

You are entitled to a second opinion from a GP trained in menopause. The Australasian Menopause Society maintains a directory of qualified clinicians.

Three takeaways

1. The median age of 47 for the first signs of perimenopause is a midpoint. Half of women experience signs earlier.

2. Regular periods do not rule out perimenopause. For many women, periods stay unchanged until they are well into the transition.

3. Normal bloods do not rule out perimenopause. For women over 45, the diagnosis is clinical — symptoms plus age, not lab values.

4. 
   

This is not your body failing you. It is your body changing — and asking for a different kind of support.

Start by tracking your symptoms over the next two to three months. Two to three months captures the cyclical pattern of perimenopausal hormones in a way that two weeks cannot. There are over 40 documented symptoms of perimenopause — most women have never seen the full list.
