You've done everything you used to do, and your body is no longer cooperating.
The workouts that used to work don't. The weight around your middle won't move.
You're hot, then cold, then wired at 3am for no reason you can name.
Your mood isn't anywhere near like it used to be (you are flat, anxious, unmotivated).
Your cycle is all over the place.
And every time you ask a doctor, the answer is some version of "well, you're getting older."
This page is for women who want to understand what is going on with their body & answers.
The Symptoms I Hear Every Week
Does This Sound Like You?
You're between 35 and 60, and something has shifted. Not all at once. It crept in.
The list below is what comes up in my clinic every week.
You wake at 2 or 3am wired, heart racing, and can't get back to sleep until 4:30
You've gained 4 to 15kg in the last 18 months with no obvious change to how you're eating or training
Your periods are now unpredictable: shorter cycles, heavier bleeds, worse PMS, or weeks of spotting
You're hot at night, sometimes in the day, sometimes for a full week before your period
The rage. You've cried in the car. You've snapped at your husband over a teaspoon
Anxiety arrived without warning (you've never really been an anxious person)
Brain fog so thick you've walked into a room and forgotten why you're standing in it
Hair thinning at the temples, along the part line, or in the shower drain
Your joints ache in the morning like you're 70
Your libido has left the building (and taken a forwarding address nobody gave you)
You're bloated and puffy in a way that feels different to bloating you've had before
Your skin has changed: drier, duller, more breakouts on the chin and jaw
If you're ticking five or more of those, you could be in perimenopause.
Your bloods probably look "normal" because standard testing doesn't catch most of what's happening.
The Science, Simplified
What Is Perimenopause
Perimenopause is the 4 to 10 year hormonal transition that happens before menopause, and it usually starts somewhere between 35 and 45.
It ends 12 months after your final period, which in Australia arrives at an average age of 51. So by the numbers, most women are in perimenopause for a decade or more, often without knowing it has started.
The pattern goes like this. Your progesterone starts dropping first, usually in your late 30s. Progesterone is the calming, steadying hormone. It supports sleep, keeps anxiety in check, balances oestrogen, and supports the GABA pathway in your brain (GABA is the neurotransmitter that helps you feel calm and fall asleep).
When progesterone drops, oestrogen is left unopposed for longer stretches of your cycle, and that is when the first wave of symptoms starts showing up: heavier bleeds, breast tenderness, PMS that feels disproportionate, mood volatility, and waking in the early hours of the morning.
Then oestrogen starts swinging. Not in a clean downward line. It spikes, it crashes, sometimes in the same week. The highs produce bloating, migraines, heavy bleeds, and emotional reactivity. The lows produce hot flushes, brain fog, joint pain, anxiety, and vaginal dryness.
This is why you can feel completely different symptoms in the same cycle, and why a single blood test on a random day almost always comes back looking "normal," because oestrogen and progesterone swing across the cycle and a one-off blood draw catches the level on that single day, not the highs and lows your body has moved through in the days before or after.
Underneath all of this, your thyroid, your insulin, your cortisol, and your gut are all shifting at the same time, because these systems do not operate in isolation.
A disruption in one creates ripple effects in the others.
This is why perimenopause symptoms are so wide-ranging.
It is not a hormonal event happening on its own, it is a whole-body recalibration that touches sleep, mood, metabolism, gut, brain, skin, bones, and cardiovascular health. (Jean Hailes has a good clinical overview of the stages if you want to read further.)
I find in my clinic that most women are 3 to 5 years into perimenopause by the time they are told it is perimenopause.
That is not your fault, and it is not your GP's fault either. It is a gap in how women's health is taught and tested, and it is fixable once you know what you are looking for.
From the Clinic
Perimenopause Symptoms I See Most Often
These are the ones that come up every week. If you're ticking multiple, it is worth investigating rather than waiting it out.
Night waking at 2-3am, often with a racing heart or feeling hot
Weight gain around the middle that will not shift with diet or exercise
Irregular periods: shorter cycles, heavier bleeds, skipped periods, spotting
Hot flushes and night sweats (sometimes mild, sometimes drenching)
Anxiety or low mood that is new or much worse than it used to be
Rage and emotional volatility, particularly the week before a period
Brain fog, word-finding issues, forgetting why you walked into a room
Hair thinning along the part line, at the temples, or in the shower drain
Joint aches and morning stiffness
Low libido and vaginal dryness
Breast tenderness and fibrocystic changes
Skin changes: acne along the jawline and chin, drier skin, loss of tone, sagging skin
Bloating, constipation, reflux (gut symptoms commonly worsen in perimenopause)
Heart palpitations (often harmless, always worth checking)
Urinary urgency and recurrent UTIs, thrush, bacteria vaginosis
If you are ready to get to the root cause of your perimenopause symptoms, with a clinical plan built around your body and your life, this is where we start.
The Mechanisms Behind It
What's Going On With Your Perimenopause Symptoms
Most perimenopause advice stops at "your hormones are changing." Which is true, and also not useful. The useful question is which hormones, how, and what else in your body is being pulled along with them.
This is what I look at in clinic.
Progesterone drops first
Progesterone is the first hormone to decline in perimenopause, usually in your late 30s or early 40s. It is the calming hormone, the one that keeps your nervous system steady, supports your sleep, and balances the more stimulating effects of oestrogen. Progesterone also supports your GABA pathway, which is the brain's main calming system. Think of GABA as the handbrake on your nervous system. Pull it up and everything settles.
When progesterone drops, you lose some of that handbrake support, and your system becomes more reactive, more anxious, and less able to stay asleep through the night.
This is why sleep is one of the first things to change for many women in perimenopause.
You might have been someone who always slept well, and now you are waking at 2am wired, heart racing, mind switching on, and it takes you two hours to get back to sleep. That is not random. That is your nervous system without its handbrake.
Progesterone is also the hormone that balances oestrogen through the second half of your cycle. When progesterone drops, oestrogen is unopposed for longer, which is where heavy bleeds, breast tenderness, fluid retention, and PMS that feels disproportionate start coming from.
I see this in clinic constantly in women in their late 30s and early 40s who have been told they are "too young for perimenopause."
The bloods often look fine because standard tests are not picking up what is happening across the cycle, and the symptoms themselves are the most useful clinical information at this stage.
Oestrogen doesn't decline smoothly, it swings
Oestrogen does not go down in a clean line through perimenopause. It swings. High, then low, sometimes within the same week. And each end of that swing produces a different set of symptoms, which is why you can feel like you are losing your mind in the same cycle that you feel bloated and premenstrual for 14 days.
The highs cause breast pain, migraines, heavy bleeds, bloating, and emotional reactivity. The lows cause hot flushes, brain fog, joint pain, anxiety, and vaginal dryness. A single oestrogen blood test captures one moment in that rollercoaster, which is why so many women come to me with a stack of "normal" results and symptoms that are very clearly not normal. This is where functional testing earns its keep. I use DUTCH Complete and DUTCH Cycle Mapping to look at how you are producing, using, and clearing your oestrogen across a full cycle, because that is the information that standard pathology simply does not collect.
Your gut microbiome plays a direct role in oestrogen balance
Your gut contains a specific group of bacteria called the oestrobolome, and its job is to process used oestrogen so your body can excrete it through the bowel.
When your oestrobolome is healthy and your gut is functioning well, oestrogen that has done its job is packaged up, sent out, and that is the end of it.
When the gut is inflamed, dysbiotic (too much of the wrong bacteria, not enough of the right ones), or moving too slowly, the packaged oestrogen gets unpackaged and reabsorbed back into circulation.
The same hormone circulates around your body a second and third time, adding to the oestrogen load that should have left days ago.
This is one of the reasons so many women develop new gut symptoms (bloating, reflux, constipation) at exactly the same time as their hormone symptoms get worse. It is not two separate problems. It is the same problem showing up in two systems. If the gut is not addressed, hormone support will only get you partway there. Fixing the gut in perimenopause is a hormonal intervention, not just a digestive one.
The pregnenolone steal (why stress exacerbates the symptoms)
The mechanism most women never hear about is the pregnenolone steal, and it is one of the most clinically important to understand.
Progesterone and cortisol (your main stress hormone) are both made from the same raw material in your body, a precursor called pregnenolone.
Under chronic stress, your body prioritises survival over reproduction every time, so more of that raw material gets diverted into making cortisol, and less is available for progesterone production.
This is called the pregnenolone steal, and it is one of the fastest accelerators of perimenopausal symptoms I see in clinic.
On top of that, elevated cortisol raises blood sugar, worsens insulin sensitivity, promotes belly fat storage (particularly the visceral fat around your organs), disrupts sleep, and inflames the gut lining. Every single one of those things then feeds back into every other perimenopause symptom.
This is why the "eat less, move more" advice fails so many women at this stage. If your cortisol is chronically elevated and your nervous system is dysregulated, your body is not in a state where weight will shift or sleep will improve, no matter how clean the food is or how hard you train.
Nervous system regulation is one of the central parts of a clinical perimenopause plan, because cortisol regulation directly affects progesterone production, sleep quality, insulin sensitivity, and gut function, and until cortisol comes down the rest of the protocol can only do so much. Everything else works better when it is balanced.
Thyroid overlap (and why standard testing usually misses it)
Perimenopause and thyroid dysfunction look almost identical on paper: fatigue, weight gain, hair loss, mood changes, cold hands, constipation, brain fog. This is not a coincidence.
The hormonal shifts of perimenopause affect thyroid function directly, and autoimmune thyroid conditions like Hashimoto's very commonly present for the first time in a woman's late 30s or 40s.
The two often run side by side.
The problem is that standard thyroid testing in Australia usually stops at TSH.
TSH alone is not enough, and I see this missed constantly. Y
our TSH can be sitting in the "normal" range while your free T3 is too low, your reverse T3 is too high, your antibodies are flagging early autoimmune activity, and your body is struggling significantly to convert and use thyroid hormone.
Thyroid panels are recommended for the women I work with in perimenopause: TSH, free T3, free T4, reverse T3, TPO antibodies, and thyroglobulin antibodies.
Without the full picture, you will spend years chasing symptoms that are half hormonal and half thyroid, and getting partial results.
Insulin sensitivity starts slipping (and this is why belly weight won't budge)
Oestrogen plays a protective role in how well your body responds to insulin.
When oestrogen is healthy and stable, your cells open the door to insulin easily, glucose moves out of your bloodstream efficiently, and your metabolism runs well. As oestrogen starts fluctuating and declining in perimenopause, that protective effect weakens.
Your cells become less responsive, your pancreas compensates by producing more insulin, and elevated insulin promotes fat storage in a very specific pattern: belly, waist, upper body, and arms. These areas have more insulin receptors than fat cells elsewhere, which makes them more responsive to the storage signal.
I see this in clinic every week. Women who are eating well, training consistently, doing everything they have been told to do, and the weight around their middle will not move. The hormonal environment (elevated insulin, often combined with elevated cortisol) will not permit fat release until those levels come down. This is a biochemical problem, and no amount of willpower or calorie-cutting will override it while those hormones are running the show.
The good news is that insulin sensitivity is one of the fastest systems to respond to dietary change.
A specific nutrition approach (protein at every meal, plenty of vegetables, smaller intentional amounts of carbohydrates, meals spaced 4 to 5 hours apart) combined with strength training starts shifting insulin sensitivity within weeks. It is usually the first piece that starts to move once we get the full plan in place.
My Approach
How I Work With Perimenopause
My approach is root-cause, systems-based, and built for real life.
You have a job, a family, a schedule that does not pause for your hormones.
Your plan is built around that, not against it.
And I am not going to tell you it is just your age, dismiss your symptoms, or send you away without a clear plan.
Food as Medicine
Nutrition is the foundation of your perimenopause plan, and thanks to my Graduate Certificate in Culinary Nutrition Science alongside my clinical qualifications, your food plan is delicious, practical, and designed around your life.
It is built around what your body needs through this hormonal transition, based on your clinical presentation, not a generic template pulled off the internet.
I look at your symptoms, blood sugar response, inflammation levels, nutritional gaps, and the specific foods that support the systems under most pressure in perimenopause: hormones, liver, gut, thyroid, adrenals, and metabolism.
You also get a custom recipe book matched to your plan, so you are never staring at a protocol wondering what to cook on a Tuesday night.
The goal is a way of eating you can sustain through perimenopause and beyond, that still lets you enjoy a margarita or pizza on a Friday night.
Supplements and Herbal Medicine
Supplements and herbal medicine are two of the most powerful clinical tools I use in perimenopause, and you get access to practitioner-only prescriptions built specifically for your body.
These are the highest-quality clinical formulations available in Australia, with therapeutic doses and activated forms that absorb and work in the body.
A different tier entirely to anything on a chemist shelf.
Your protocol is matched to your perimenopause symptoms, test results, and the systems we are working on, whether that is hormone balance, sleep, mood, energy, or gut function.
Herbal medicine is one of the oldest and most evidence-backed forms of medicine in existence, and when prescribed correctly for perimenopause, it often produces results faster than women expect.
I adjust your prescription across the package as your body responds, so you are always taking what is clinically useful and nothing you do not need.
Nervous System Regulation
Your nervous system regulates almost every other system in the body, and when it is held in a chronic stress state during perimenopause, hormone changes become more disruptive than they need to be.
Digestion slows, hormonal balance suffers, sleep quality declines, inflammation rises, and your body holds onto weight regardless of your diet.
Chronic stress is one of the most significant contributors to perimenopause symptoms, and it is the part most treatment plans overlook.
Your plan includes clear, practical strategies that fit into a busy life: vagus nerve support, short breathwork practices, sleep support including circadian rhythm work and clinical strategies if your sleep is disrupted, stress regulation built around your capacity, and movement that supports your system rather than adding to it.
Most women notice improvement within the first few weeks.
Advanced Testing & Integrative Pathology Review
You have access to advanced functional testing when it is clinically useful for your case and your budget.
This includes DUTCH Complete and DUTCH Cycle Mapping for a detailed look at your hormones, GI-MAP for gut and microbiome (a significant piece of the perimenopause picture), full functional blood panels, DNA and nutrigenomic testing, organic acids, advanced thyroid panels, and food sensitivity testing when indicated.
I only recommend testing that is going to meaningfully inform your treatment direction.
I also review your pathology through an integrative lens using functional optimal ranges, which are tighter than standard population reference ranges.
A result can sit inside the "normal" range and still be contributing to your perimenopause symptoms, and this is often where the clinical answers are found.
80/20 Always
You can have the wine. You can have the margarita on a Friday. You can have the pasta, the cheese platter, and the slice of birthday cake.
Restriction, perfectionism, and constant dieting work against your hormones, your nervous system, and your long-term consistency, which is the last thing your body needs in perimenopause.
They also compromise your relationship with food, which is one of the most difficult things to repair in women in this stage of life.
Your plan is built to be sustainable for life, not for 30 days, so you can navigate perimenopause and enjoy your life at the same time.
The goal is a way of eating and living that fits into a full social life and continues to support your clinical outcomes.
Realistic & Built Around Your Life
Your plan is designed around how busy you are, your schedule, who you cook for, how much time you have, and the capacity you are carrying in this stage of life.
Simple, sequenced, and achievable.
I will not hand you a protocol that requires hours in the kitchen, a fridge full of obscure ingredients, or a morning routine longer than the average commute.
No plan produces results if it does not fit your life, which is why most generic programs fail women in perimenopause.
Yours is built to fit yours, step by step, in the clinical order your body needs through this hormonal transition.
Naturopath In Your Pocket
Between consults, you have direct messaging access to me for questions about your protocol, new symptoms you want to flag, situations that change the plan, or progress you want to share.
You are not sitting with a clinical question for weeks waiting for your next appointment, and you are not working through the complex parts on your own.
Perimenopause symptoms shift month to month, and having clinical support between sessions makes a significant difference to outcomes across a multi-month protocol.
Most women tell me this is one of the most valuable parts of working together.
Mindset & Your Relationship With Food
Most women I see in perimenopause already have a bit of an idea of what they need to do.
They have read the books, followed the accounts, bought the supplements, and started the protocols.
What keeps them stuck is what is underneath: all-or-nothing thinking, self-sabotage when progress begins, food guilt, body image concerns, and years of yo-yo dieting that now feel amplified in perimenopause.
This thinking consistently undermines the clinical work in every protocol a woman has tried before.
Your plan includes work on these patterns as part of your clinical care, because a treatment plan does not produce lasting results if the thinking underneath it is pulling in the opposite direction.
This is part of your care, not an extra.
Your Questions, Answered
Perimenopause FAQs
Can a naturopath and nutritionist help with perimenopause?
Yes. A naturopath and nutritionist can be one of the most useful practitioners to see in perimenopause because the approach is root-cause and systems-based. I look at hormones, gut, thyroid, insulin, cortisol, liver function and nutrition together rather than treating one symptom at a time. For Australian women who feel dismissed by conventional care, or who want support alongside HRT, it is often the piece they have been missing.
What is the difference between a naturopath and nutritionist and a GP for perimenopause?
A GP is usually your first stop for diagnosis, medication, and HRT discussion, which is valuable clinical care. A naturopath and nutritionist takes a root-cause, holistic approach to your health, because what happens in one system of the body affects every other system. Your hormones, gut, thyroid, nervous system, and metabolism all communicate with each other, and treating them in isolation rarely gives lasting results.
In clinic, I use functional testing (DUTCH, GI-MAP, full thyroid panels), practitioner-only supplements, custom herbal medicine, and personalised nutrition to support all of these systems together.
This is a comprehensive, intensive, and hands-on approach. You get a personalised clinical plan, ongoing support between consults, and the time to work through your perimenopause symptoms.
The two approaches are complementary, not either-or. I work with many women who are on HRT through their GP and working with me on the gut, nutrition, nervous system, and lifestyle foundations that HRT does not replace.
How long does it take to see results for perimenopause?
Energy and digestion usually start to improve in the first 2 to 4 weeks. Mood, skin, and early symptom relief follow between 4 and 8 weeks. Cycle regulation and deeper hormonal change come across the 3 to 6 month mark. Every woman is different, but most describe significant improvement within the first few months of working together.
Can I work with you if I am on HRT or the pill?
Yes. I work with women on HRT, the pill, antidepressants, and other medications regularly. The goal is to support your body through perimenopause regardless of what else you are taking.
I do not prescribe or deprescribe any medication, that conversation belongs with your GP or specialist. I support the foundations (gut, nutrition, nervous system, lifestyle) that HRT does not replace.
What testing do you use for perimenopause?
Tests vary depending on each person, and recommendations are based on your history and symptoms. Not every woman needs every test.
Commonly, I will run fasting insulin, inflammation markers, and nutritional markers including vitamin D, folate, active B12, and a full iron study. Alongside this, a full blood panel with full thyroid (TSH, free T3, free T4, reverse T3, TPO and thyroglobulin antibodies), HbA1c, and lipids.
Where it is clinically useful and fits your budget, I also use DUTCH Complete or DUTCH Cycle Mapping for detailed hormone pattern analysis, GI-MAP stool testing when gut symptoms are present, and other functional tests when indicated.
Do I need a GP referral to see you?
No. Naturopaths and nutritionists in Australia do not require a GP referral. You can book directly.
Do you consult online across Australia?
Yes. All my consultations run online via telehealth, which means I work with women in every state and territory. Most of my clients are in Sydney, Melbourne, Brisbane, Perth, Adelaide and regional NSW, but geography is not a barrier.
What does it cost to work with you for perimenopause?
The initial consultation is 90 minutes and includes a personalised plan you leave with. Follow-up consultations run 30 to 60 minutes depending on what is needed. Testing is additional and quoted up front so there are no surprises. Full pricing is on the Consultations page (here). Private health rebates may apply depending on your fund.
Do you order blood tests?
Yes. I can organise pathology and functional testing directly through the private labs I use in clinic, including full functional blood panels, DUTCH Complete, DUTCH Cycle Mapping, GI-MAP, DNA and nutrigenomic testing, and other specialised tests when indicated.
These are out of pocket because they are not covered by Medicare.Some standard blood tests are covered by Medicare when ordered through a GP, so for those panels I will write you a clear list of exactly what to ask your GP for, which keeps the cost down.Functional tests are always private and quoted up front, so you know the cost before committing to anything.
I will only ever recommend testing that is going to meaningfully inform your clinical plan.
Will I have to give up wine, coffee or sugar?
Not forever. Not all at once. I work on the 80/20 rule personally and professionally. There will be periods where reducing certain things speeds the process up (particularly in the early weeks of rebalancing blood sugar or the gut), but the plan is always built for sustainability.
You can have the glass of wine. You can have the margarita. Restriction is not the strategy.
