Am I Too Young for This? What You Need to Know About Early Perimenopause
You're in your late 30s. Your periods have become unpredictable. You're waking up at 3am drenched in sweat, snapping at people you love for no good reason, and feeling like your brain has been replaced with cotton wool. You google your symptoms and the word "perimenopause" keeps coming up — but you dismiss it almost immediately.
Perimenopause? Surely not. I'm too young for that.
Here's the thing: you might not be.
Perimenopause Doesn't Wait Until Your 50s
Most of us grew up thinking menopause was something that happened in your early 50s and that you'd get some kind of warning before it arrived. The reality is more complicated — and earlier.
Perimenopause is the transition phase before menopause, when your ovaries gradually start producing less oestrogen. It can begin anywhere from your mid-30s to your late 40s, with most women entering it somewhere in their early-to-mid 40s. But for a significant number of women, it starts much sooner than that (Women’s Health Australia, 2026).
Menopause itself is defined as the point when you haven't had a period for 12 consecutive months. Everything leading up to that? That's perimenopause — and it can last anywhere from a few months to a full decade.
So if you're 37 and something feels off, it's not all in your head.
What Does "Early" Perimenopause Actually Mean?
There's an important distinction worth knowing here.
Early perimenopause (beginning between ages 40 and 45) is more common than many people realise. It's not considered unusual or alarming on its own, though it's worth discussing with your doctor.
Premature ovarian insufficiency (POI) — sometimes called premature menopause or ovarian failure — is when the ovaries stop functioning normally before the age of 40. The ovaries stop producing eggs and sex hormones (estrogen, progesterone, testosterone). This affects around 4 in 100 women and is absolutely something to speak to a GP about, as it carries additional health considerations around bone density and heart health (ESHRE, 2024).
And then there's the middle ground: women in their late 30s who are starting to notice hormonal shifts that don't yet have a clear label. Their cycles are changing. Their sleep is disrupted. Their moods feel harder to manage. They don't fit neatly into a diagnosis — but something is clearly happening. While it may not be POI, early hormonal decline needs management to prevent risks to bone health, cardiovascular health, and emotional well-being. This should be discussed with a doctor who is experienced in dealing with perimenopause. Lifestyle factors, like high stress, extreme exercise, significant weight changes, can be a cause. A naturopath can help address these factors - why not find out how they can help and book in for a free discovery call. Ideally, they work with your doctor to ensure the best outcome for you.
If this sounds like you, you're not alone and you're not imagining things.
The Symptoms That Often Get Missed (or Misattributed)
One of the reasons early perimenopause goes unrecognised for so long is that its symptoms are remarkably easy to explain away.
Irregular periods? Must be stress. Poor sleep? You've just got a lot on. Anxiety that seems to come from nowhere? Perhaps you need to slow down. Brain fog and forgetfulness? Everyone feels like that sometimes.
The symptoms most commonly associated with perimenopause include:
Irregular or changing periods — heavier, lighter, more frequent, or skipped altogether
Hot flushes and night sweats — the most well-known symptoms, but not universal
Sleep disruption — difficulty falling asleep or staying asleep, often linked to night sweats
Mood changes — irritability, low mood, anxiety, or feeling emotionally reactive in ways that feel out of character
Brain fog — difficulty concentrating, forgetting words, feeling mentally sluggish
Reduced libido — a drop in sex drive that can feel sudden or gradual
Vaginal dryness — often not talked about, but very common
Heart palpitations — can feel alarming, but are a recognised symptom of hormonal fluctuation
(Menopause Alliance Australia, 2026)
Not everyone experiences all of these, and they won't all appear at once. For some women, the first clue is simply that their once-reliable cycle has become unpredictable. For others, it's the mood changes or the sleep issues that prompt them to look for answers.
Why Is It So Hard to Get Answers?
Many women who suspect early perimenopause find the process of getting answers frustrating. Part of the problem is that hormone testing — while available — is notoriously unreliable during perimenopause. Because oestrogen levels fluctuate so dramatically from day to day, a single blood test can't give you a definitive picture.
This means diagnosis is largely based on your symptoms, your age, your cycle history, and ruling out other causes (thyroid issues, for example, can mimic perimenopausal symptoms closely).
The most important thing you can do is keep track of what you're experiencing — when symptoms occur, how often, how severe — and bring that information to a healthcare provider who takes your concerns seriously. If you feel dismissed, it is absolutely reasonable to seek a second opinion. Perimenopause is still an underserved area of women's health, and not every GP has deep experience in it.
So What Can You Do?
The good news is that perimenopause, whenever it starts, is manageable. There are real options available.
Hormone therapy (HT) is one of the most effective treatments for perimenopausal symptoms and is considered safe for most healthy women. It works by supplementing the hormones your ovaries are producing less of, and can make a significant difference to quality of life.
Lifestyle adjustments also play a meaningful role. Regular exercise, a nutrient-rich diet with plenty of protein, fibre and healthy fts, reducing alcohol and caffeine, and prioritising sleep hygiene can all help ease symptoms. A naturopath can help with making these adjustments.
(Women’s Health Australia, 2026)
Non-hormonal options exist too, including certain herbs that can help with specific symptoms like hot flushes. However, these should be discussed with a qualified nutritionist or naturopath. Off-the shelf products, whilst tempting and easily accessible, don’t take your specific situation (your health history, the mediations you might be taking, your gut health, your health goals etc) into account. The result is that they often don’t work and you have wasted a lot of money!
The right approach is different for every person, which is why a conversation with a knowledgeable healthcare provider — ideally one who specialises in menopause — is so valuable.
The Bottom Line
If you're in your late 30s or early 40s and something feels different — trust that instinct. Perimenopause doesn't come with a minimum age requirement, and being "too young" is far less common an explanation than many women are led to believe.
You know your body. If the symptoms are there, they deserve to be taken seriously — by your doctor, and by you.
