WHAT IS PERIMENOPAUSE?

Perimenopause is the natural transition phase your body moves through in the years leading up to menopause. The word literally means 'around menopause', and it's the time when your hormone levels - particularly oestrogen and progesterone - start to fluctuate and gradually decline.

Menopause itself is officially marked as the point when you've gone 12 consecutive months without a period. Everything that happens in the lead-up? That's perimenopause. And while menopause is a moment in time, perimenopause is an entire phase - one that can last anywhere from a few years to a full decade.

It's a totally normal, natural part of life - but knowing the early signs of perimenopause can make a world of difference to how you navigate it.

WHEN DOES PERIMENOPAUSE START?

For most women, perimenopause starts somewhere between their mid-40s and early 50s, but it can begin earlier. Some people experience the first signs of perimenopause in their late 30s, which can feel confusing if no one's ever mentioned it as a possibility.

Early perimenopause is often missed or misdiagnosed because the symptoms can be subtle, intermittent, and easy to blame on stress, busy life, or 'just getting older'. The key thing to know? If your cycle starts shifting and you're feeling different in ways you can't quite explain, perimenopause might be on the table - even if you're younger than you'd expect.

EARLY SIGNS OF PERIMENOPAUSE TO LOOK OUT FOR

Perimenopause symptoms can vary wildly from person to person - some barely notice the transition, others feel it hard. Here are the most common early signs to keep on your radar.

CHANGES TO YOUR PERIOD

This is usually the first clue. Your cycle might get shorter or longer, your flow might become heavier or lighter, you might skip months, or you might bleed more frequently. Spotting between periods can also be common.

HOT FLUSHES AND NIGHT SWEATS

That sudden wave of heat creeping up your chest and face? Classic. Hot flushes (and their nighttime cousin, night sweats) are caused by fluctuating oestrogen affecting your body's internal thermostat.

MOOD SWINGS, ANXIETY AND BRAIN FOG

Most of us would be familiar with mood changes during our menstrual cycles because we would have likely experienced them during PMS, and unfortunately this extends into perimenopause, too. Shifting hormones can mess with neurotransmitters like serotonin, which is why you might feel more anxious, irritable or emotionally fragile than usual. Brain fog - that frustrating inability to find a word or focus - is also very common.

SLEEP DISTURBANCES

Trouble falling asleep, waking at 3am for no reason, or feeling unrested even after a full night? Hormonal shifts (and those pesky night sweats) can disrupt sleep when you menstruate but also in a big way during perimenopause.

CHANGES IN LIBIDO AND VAGINAL DRYNESS

As oestrogen dips, you may notice a drop in libido and changes in vaginal lubrication. Dryness, discomfort during sex, and increased risk of UTIs can all show up. Totally normal, and totally manageable with the right support.

UNCOMMON PERIMENOPAUSE SYMPTOMS

Most women will recognise when they're experiencing the more obvious and widely discussed perimenopause symptoms, but there are some lesser-known symptoms that could also be related to this transition, as our bodies are producing less oestrogen. Be on the lookout for:

• Thinning hair, or other hair changes like dryness
• Changes in body odour
• Body zaps/electric shock type sensations
• Phantom smells (like smelling smoke, even though nobody is smoking around you)
• Tingling in the hands and feet
• Dry eyes
• Itchy ears

HOW LONG DOES PERIMENOPAUSE LAST?

The honest answer? It varies. On average, perimenopause lasts around four to eight years, but for some women it's shorter (a year or two) and for others it can stretch out to a full decade. You're considered to have officially reached menopause when you've gone 12 consecutive months without a period.

The length and intensity of your transition is influenced by genetics, lifestyle, overall health, and whether you've had any medical interventions (like a hysterectomy) that affect your hormones.

HOW TO MANAGE PERIMENOPAUSE SYMPTOMS

The good news? There's a lot you can do to support your body through perimenopause. A few starting points:

• Track your symptoms. Keep a simple log of your cycle, sleep, mood and any flushes - it helps you (and your doctor) spot patterns.
• Move your body. Regular exercise - especially strength training and walking - supports bone density, mood and sleep.
• Eat to support your hormones. Prioritise protein, fibre, healthy fats and plenty of plants. Phytoestrogen-rich foods like flaxseed, chickpeas and tofu may help.
• Mind your sleep. Cool bedrooms, breathable bedding and a consistent wind-down routine can make a real difference.
• Manage stress. Cortisol and oestrogen don't play nicely. Meditation, breathwork, or even a daily walk can help regulate both.
• Consider professional support. Naturopaths, hormone specialists, endocronologists and GPs can guide you through options like Menopausal Hormone Therapy (MHT) if needed.

WHEN TO SEE YOUR DOCTOR

Perimenopause is normal, but that doesn't mean you have to suffer through it. Book in with your GP if you're experiencing:

• Very heavy or prolonged bleeding
• Bleeding between periods or after sex
• Symptoms that interfere with your daily life, work or relationships
• Severe mood changes or anxiety
• Hot flushes or night sweats that are disrupting your sleep significantly

Your doctor can help confirm what's going on, rule out anything else, and talk through options to ease symptoms. They may also suggest a blood test that measures your hormone levels involved in the perimenopausal/menopausal transition.

And of course, if you don't feel like your doctor is supporting you, or treating your symptoms seriously, find one that will.

FINAL THOUGHTS

Perimenopause is one of the most significant hormonal shifts you'll ever experience, but it's also one of the least talked about. The more we normalise it, share information, and check in with each other, the easier the transition becomes.

You're not losing the plot - your hormones are simply moving into a new chapter. With the right support, knowledge and self-care, this phase of life can be just as vibrant, powerful and you as every other.

PERIMENOPAUSE FAQs

CAN YOU STILL GET PREGNANT DURING PERIMENOPAUSE?

Yes! Until you've had 12 consecutive months without a period, pregnancy is still possible. If you don't want to conceive, keep using contraception.

IS PERIMENOPAUSE THE SAME AS MENOPAUSE?

No. Perimenopause is the transition leading up to menopause. Menopause itself is the single point in time marking 12 months without a period. Everything after that is called post-menopause.

CAN PERIMENOPAUSE START IN YOUR 30s?

Yes, although it's less common. Early perimenopause can start in your late 30s. If menopause itself happens before age 40, it's known as premature menopause, and is worth discussing with a specialist.
