Nobody mentioned perimenopause.
That’s the problem. And it’s happening to women across Australia every single day.
What Perimenopause Actually Is
Perimenopause is the transitional phase leading up to menopause — the years during which your ovaries gradually begin producing less oestrogen and progesterone. It ends when you’ve gone twelve consecutive months without a period. That endpoint is menopause. Everything before it? That’s perimenopause.
It can last anywhere from two to twelve years. The average is around four to eight.
Most women don’t know this. They know what menopause is — hot flushes, the end of periods, a phase associated with being older. Perimenopause doesn’t carry the same cultural recognition, which means millions of women are experiencing a profound hormonal shift without a name for it, without clinical support, and without the understanding that what they’re feeling is physiological rather than personal failing.
That’s not an acceptable gap. It’s one we need to close.
When Does Perimenopause Start?
This is where the information gap does the most damage. Most women assume perimenopause is something that happens in their 50s. For many, it begins in their late 30s or early 40s.
Symptoms can appear years before periods become irregular — which is the marker most clinicians and patients watch for. By the time the menstrual cycle becomes noticeably disrupted, hormonal fluctuations may have been affecting mood, sleep, cognition, and energy for considerably longer.
There’s also a condition called premature ovarian insufficiency (POI), where perimenopausal changes begin before age 40. It affects roughly 1 in 100 women. It’s frequently undiagnosed or misdiagnosed — most commonly as depression, anxiety disorder, or stress-related fatigue.
The Symptoms Nobody Connects to Hormones
Here’s what makes perimenopause so easy to miss: the earliest symptoms often have nothing to do with periods or hot flushes. They’re subtler, more diffuse, and far more likely to be attributed to stress, overwork, or mental health conditions.
Mood changes and anxiety. Oestrogen plays a significant regulatory role in serotonin and dopamine production. As levels begin to fluctuate — not drop steadily, but fluctuate wildly — many women experience anxiety that feels different from anything they’ve had before. It can arrive suddenly, without an obvious trigger, and it doesn’t always respond well to standard anxiety treatments because it isn’t primarily a psychological problem. It’s hormonal.
Sleep disruption. Progesterone has a sedative, calming effect on the nervous system. As it declines, sleep becomes lighter and more fragmented. Night sweats — even mild ones — further interrupt sleep architecture. Women in perimenopause frequently describe waking at 3am unable to return to sleep, not because of stress, but because of hormonal withdrawal their body hasn’t been told to expect.
Brain fog and cognitive changes. Oestrogen is deeply involved in neural function, memory, and processing speed. The cognitive changes that accompany perimenopause are real, measurable, and distressing — but they’re almost universally attributed to ageing, burnout, or depression before anyone checks hormones. Women describe losing words mid-sentence, forgetting things they’d always remembered, feeling mentally slower than they’ve ever been.
Joint pain and physical changes. Oestrogen has anti-inflammatory properties. Its decline often correlates with increased joint stiffness and pain — another symptom almost never connected to perimenopause without prompting.
Changes in libido and vaginal health. Reduced lubrication, discomfort during sex, and lowered libido are direct consequences of oestrogen decline. They’re among the most undertreated symptoms in women’s health — partly because they’re underdisclosed, and partly because clinicians aren’t always asking.
Palpitations. Yes, heart palpitations. Oestrogen helps regulate the autonomic nervous system. Its fluctuation can cause irregular heartbeats that send women to cardiologists rather than endocrinologists. This is more common than the literature tends to reflect.
Why It’s So Frequently Missed
The diagnostic gap isn’t a mystery. It’s the product of several overlapping problems.
Perimenopause doesn’t show up cleanly on standard blood tests. FSH (follicle-stimulating hormone) levels can confirm menopause, but during perimenopause — when hormones are fluctuating rather than declining steadily — a single blood draw will often return normal results. A woman can be experiencing significant perimenopausal symptoms while her bloods look entirely unremarkable.
This means diagnosis relies heavily on a clinician who knows what to listen for, asks the right questions, and considers hormonal health in context — not just in isolation.
Most women are also presenting with individual symptoms rather than the full picture. One appointment for sleep, one for anxiety, one for joint pain. No single consultation maps the pattern. And without that mapping, perimenopause doesn’t enter the conversation.
There’s also a generational silence around women’s hormonal health that’s only recently begun to shift. Women who are in perimenopause now were raised in a medical culture that normalised dismissing women’s symptoms, pathologised emotion, and treated menopause as an embarrassing inevitability rather than a clinically significant physiological event. Many have internalised that silence. They don’t advocate for themselves as loudly as they should, because they’ve been trained not to.
What Treatment Actually Looks Like
Perimenopause isn’t something to push through. It’s something to treat — and the options are broader, more evidence-based, and more effective than many women realise.
Hormone Replacement Therapy (HRT). The evidence for HRT has been substantially rehabilitated in the past decade. Earlier concerns about breast cancer risk — stemming largely from a flawed 2002 study — have been revisited. Current guidance from bodies including the Australasian Menopause Society supports HRT as a safe and effective treatment for most perimenopausal women, particularly when commenced within ten years of menopause. Modern HRT formulations use bioidentical hormones, carry a more nuanced risk profile, and have demonstrated significant benefits for sleep, mood, cognition, bone density, and cardiovascular health.
Non-hormonal options. For women who can’t or don’t want to use HRT, there are evidence-based alternatives. Certain antidepressants (particularly SSRIs and SNRIs) have demonstrated efficacy for vasomotor symptoms and perimenopausal mood disturbance. Cognitive behavioural therapy (CBT) has an evidence base for both sleep and hot flushes. Mindfulness-based approaches have shown measurable benefit for anxiety.
Lifestyle support. Resistance training has emerged as particularly important during perimenopause for bone density, lean muscle retention, metabolic function, and mood. Dietary adjustments — particularly protein adequacy and calcium — matter more than they did in earlier decades. Sleep hygiene becomes more critical as sleep architecture becomes more fragile.
Targeted supplementation. Magnesium, for sleep and nervous system regulation. Vitamin D, for bone health and mood. These aren’t substitutes for clinical treatment but they’re appropriate adjuncts.
The right plan is individual. It’s built on a complete clinical picture — not a single snapshot blood test and a script for antidepressants.
What to Do If You Think This Is You
If you’ve recognised yourself in this piece, the most important thing you can do is get a proper clinical assessment. That means speaking with a clinician who understands hormonal health, takes your symptom history seriously across all domains, and doesn’t dismiss your concerns because your bloods look normal.
You’re not imagining it. You’re not losing your mind. You’re not simply stressed or getting older or not coping well enough.
You’re experiencing a significant physiological transition that deserves clinical attention — and that’s exactly what you should be able to access.
