66 Perimenopause Symptoms & Their Root Causes

Perimenopause has 66 recognised symptoms, but they aren’t 66 separate problems.By Sandra Ishkanes, Functional Medicine Menopause Specialist · BSc, MA, DipION
Midlife can be a bumpy ride — 66 perimenopause symptoms have been identified. You’ll be glad to know they don’t all arrive at once because of the way oestrogen and progesterone levels change through the perimenopause transition. I identify two stages:
- Early perimenopause.
Mid-cycle ovulation starts skipping. Ovulation is what makes progesterone, so as it falters, progesterone falls, creating a relative oestrogen dominance, and it’s that oestrogen excess that drives the early symptoms. Periods tend to get heavier and come closer together. - Mid and late perimenopause.
Oestrogen itself starts declining, and that decline triggers three metabolic shifts: the Energy Shift, the Oestrogen Shift and the Emotional Shift. These are shifts your body is designed to make as it moves out of its reproductive years. Symptoms tend to appear when something blocks the shifts — most often the metabolic pressures of modern life — rather than because the shifts themselves are happening. That distinction matters because a blocked shift can be unblocked and symptoms can be reversed.
The following sections explain what is happening in each stage in detail.
Early perimenopause: progesterone falls first, oestrogen dominates – the Progesterone Shift
Periods are often still regular, sometimes even closer together, and the textbook picture of “low oestrogen” hasn’t arrived. What’s actually happening is closer to the opposite. Progesterone is made only when you ovulate, and ovulation is the first thing to falter, so progesterone starts dropping years before oestrogen does. That leaves oestrogen unopposed: still high, but now erratic and swinging, with nothing to steady it. So most early symptoms are signs of too much oestrogen relative to progesterone, not too little. You’re likely in this stage if your cycle is shifting but not yet erratic, and your symptoms are the heavy, tender, bloated, headachy kind.
- Allergies and sensitivities, increased. Oestrogen does two things at once: it prompts mast cells to release more histamine, and it lowers DAO, the enzyme that breaks histamine down. More made, less cleared — so histamine climbs. Old hay fever flares, new food or skin sensitivities appear, and antihistamines start to feel necessary when they never were. It’s also why symptoms can spike around ovulation and before a period, when oestrogen peaks.
- Bloating. Two things combine. Oestrogen tells the body to hold on to sodium and water, and with no progesterone left to act as a natural diuretic, that fluid builds. Meanwhile the swinging hormones slow and unsettle the gut, so trapped gas and sluggish digestion add to the distended feeling — usually at its worst by evening.
- Breasts — sore or tender. Breast tissue is exquisitely oestrogen-responsive — it’s why breasts swell and ache before a period. With oestrogen now unopposed and swinging, that stimulation is stronger and lasts longer. Later in the transition, estrone, a weaker oestrogen made in fat tissue, adds to the background load, so the soreness can drag on well into post-menopause.
- Candida or thrush — a tendency to. Oestrogen shapes the environment of both the gut and the vagina — it feeds glycogen to the vaginal microbiome, and it interacts with the estrobolome, the community of gut microbes that help process oestrogen. As oestrogen swings and that balance is disturbed, the conditions that normally keep yeast in check are lost, and thrush and candida overgrowth become more frequent.
- Constipation or diarrhoea. The gut wall is dense with oestrogen and progesterone receptors, so when those hormones swing, gut motility swings with them — speeding up and slowing down unpredictably. Many women develop an IBS-like alternation between constipation and looseness that simply wasn’t there before. Falling progesterone, which relaxes and slows the gut, tips many towards constipation in particular.
- Digestion — slower. Progesterone relaxes smooth muscle, including the muscle that propels food through the gut — so as it falls, transit can slow and meals start to “sit”, leaving a heavy, over-full feeling. Slower transit also gives the gut longer to reabsorb water, which feeds straight back into the constipation many women notice.
- Eyes — dark circles under them. This is a histamine sign. High relative oestrogen prompts mast cells to release more histamine, and histamine widens the tiny blood vessels beneath the very thin skin around the eyes — which is what casts the bluish shadow. It tends to appear alongside the other histamine symptoms of this stage, like headaches, congestion and flaring allergies.
- Eyes — puffy. This is fluid retention turning up in the most delicate place. Low progesterone and the sodium-and-water holding of unopposed oestrogen let fluid pool overnight in the loose tissue around the eyes, so they look puffiest first thing and settle as the day goes on.
- Fertility — reduced. Conception depends on regular, good-quality ovulation, and that’s exactly what becomes patchy now — both because fewer follicles remain and because the signalling that ripens them is less reliable. So natural fertility falls and becomes less predictable. It’s an expected part of the transition beginning rather than a separate fault, though for some women it’s a hard thing to meet.
- Fluid retention and puffiness. This is the whole-body version of the same water-holding effect: unopposed oestrogen drives sodium and water retention, so rings tighten, ankles swell and the face looks fuller. Because oestrogen is swinging rather than steady, it can come and go sharply across the cycle — which is itself a clue that it’s hormonal rather than dietary.
- Gall bladder symptoms. Oestrogen raises the amount of cholesterol the liver tips into bile, which thickens it and makes sludge or stones more likely. At the same time, falling progesterone slows the muscular squeeze that empties the gallbladder, so that thick bile sits and stagnates. The result is the classic picture — a dull ache under the right ribs, bloating, and feeling worse after fatty meals.
- Hands and feet — cold. High relative oestrogen can quietly suppress the thyroid: it raises the protein that binds thyroid hormone, leaving less of it free and active. A slightly underactive thyroid turns down the body’s heat production, and the hands and feet — furthest from the core — feel it first. That’s why cold extremities so often travel with fatigue, dry skin and a creeping weight gain.
- Headaches and migraines. Hormonal headaches are triggered by the drop in oestrogen, not the level — the steep fall around a period is what sets them off, which is why they cluster at that point in the cycle. In this stage the swings are bigger and less predictable than before, so the headaches are too. Alcohol, sugar and a broken night lower the threshold further, which is why a single glass of wine can now tip one off when it never used to.
- Indigestion, gas and nausea. Oestrogen and progesterone both set the pace of the digestive tract, from how fast the stomach empties to how briskly the gut moves things along. When they swing, that timing falls out of sync — food sits longer, ferments, and produces reflux, wind and queasiness. It’s the upper-gut counterpart to the bowel changes elsewhere in this stage.
- Menstrual cycle — changes to it. Your cycle is the first place the transition shows itself. It usually shortens at first — 28 days becoming 26, then 24 — because an ovary with fewer good follicles left tends to ovulate earlier. Later, cycles lengthen and start to skip as ovulation becomes unreliable. Almost everything else in this stage traces back to that single change: less ovulation means less progesterone, and progesterone is the hormone that normally keeps oestrogen in check.
- Nipples — painful or sensitive. The same unopposed oestrogen that swells breast tissue also heightens nipple sensitivity, sometimes enough to be uncomfortable against clothing. It rises and falls with the rest of the dominance cluster across the cycle and settles as oestrogen does.
- Periods — heavy or flooding. After ovulation, progesterone’s job is to mature the womb lining and then trigger a clean, complete shed. Without it, oestrogen keeps building that lining thicker and thicker, with no organised signal to release it — so when it finally comes away it can be heavy, prolonged, and arrive in floods or clots. Fibroids, which oestrogen feeds, make it heavier still. (Genuinely heavy bleeding is worth seeing your GP about — both to rule out other causes and because losing that much blood can leave you short of iron.)
Mid perimenopause: oestrogen drops and the brain runs short of fuel – the Energy Shift
This is the stage most people picture when they say “menopause” — and the one that feels most chaotic. Oestrogen itself is now falling, and cycles become genuinely unpredictable: long gaps, then a sudden return. The reason this stretch is so disorienting is a fuel problem in the brain. For your whole reproductive life the brain has run mainly on glucose, and oestrogen is what keeps it doing so; as oestrogen drops, the brain is meant to switch to a back-up fuel — ketones, made by burning your own fat stores. But a high-carbohydrate diet keeps insulin high and stalls that switch, leaving the brain unable to reach either fuel — it can’t use glucose, and ketones aren’t being made. The brain is left running short of energy, and a brain that senses it is short of fuel does the only thing it can: it fires the stress response — adrenaline and cortisol — on a loop. That stress response is what produces hot flushes, night sweats, anxiety, palpitations, brain fog, fatigue and weight gain. You’re likely in this stage if your periods are erratic and your symptoms are the hot, wired, exhausted, foggy kind.
- Appetite — increased. High, erratic insulin drives hunger, particularly in the evenings, so appetite can climb even when your real energy needs haven’t changed. Poor sleep compounds it: a short night raises the hunger hormone ghrelin and lowers the fullness hormone leptin, so a bad night reliably means a hungrier, more carb-seeking day.
- Appetite — loss of. In some women the picture flips. A constantly switched-on stress response diverts blood away from the gut and dampens hunger signals, so appetite falls and meals feel unappealing. It tends to travel with the nausea and slowed digestion of a body stuck in fight-or-flight.
- Blood-sugar crashes. As oestrogen falls, cells become more insulin-resistant, so blood sugar swings more violently — spiking after a meal, then crashing. The crash brings shakiness, irritability, sweating and a sudden, urgent hunger. Each crash is also a small trigger for the stress response, which is part of why a dip can tip straight into anxiety or a flush.
- Body odour — changes in. A constantly active stress response changes things you’d never connect to it. Higher cortisol alters the make-up of sweat and shifts the skin’s microbiome, so the bacteria acting on that sweat change — and so does how you smell. Stress sweat, from the apocrine glands, is also more odour-producing than ordinary sweat.
- Brain fog and memory lapses. This frightens women more than almost anything, because it can feel like early dementia — and it isn’t. Memory, word-finding and concentration are enormously energy-hungry, and a brain caught mid fuel-change can’t power them reliably, so words vanish mid-sentence and threads are lost. The reassurance worth holding onto: it lifts as the brain’s fuel supply is restored. It’s a supply problem, not decline.
- Cravings for sugar and carbs. A brain short of fuel asks for the fastest source it knows — sugar and refined carbohydrate. The craving is a real signal of the energy problem, not weak willpower. The catch is that giving in spikes insulin, and high insulin is exactly what blocks the switch to ketones — so the quick fix deepens the stall and brings the next craving sooner.
- Dizziness and unsteadiness. A brain running low on fuel handles balance and spatial processing less smoothly, which can feel like wooziness, swimminess or being subtly off-balance. Oestrogen also influences the inner ear, so its fall can add a true vertigo-like edge for some women. It tends to track the other energy symptoms — worse when tired, stressed or hungry.
- Electric-shock sensations. A brief, strange zap — often felt in the head or just under the skin, and frequently just before a flush. It’s thought to come from the nervous system misfiring as the brain’s fuel supply and temperature control become unstable, sending a stray burst of activity down a nerve. Disconcerting, but harmless in itself, and it tends to come and go with the flushes.
- Facial flushing and pallor. The same vasomotor instability behind hot flushes plays out in the face minute to minute — small blood vessels constricting and dilating, so colour swings between pale and flushed. It’s the visible, surface version of a temperature-control system that has lost its steadiness.
- Faintness. When blood sugar dips and the brain’s fuel supply drops with it, the brain protects itself by making you feel light-headed and in need of sitting down. It’s most likely after a long gap without eating, on standing up quickly, or in the middle of a blood-sugar crash. Steadier blood sugar usually settles it.
- Fatigue, crushing. At its most extreme the shortfall becomes a bone-deep tiredness that sleep doesn’t touch — because the problem isn’t lack of rest, it’s that the cells aren’t getting reliable fuel. Broken sleep and the constant drain of a switched-on stress response pile on top. This is the symptom women most often have brushed off as “just being busy”, when it’s actually metabolic.
- Heartbeat — irregular or racing. The adrenaline surges of the stress response can make the rhythm feel uneven or suddenly fast. Falling oestrogen also affects the autonomic nerves that fine-tune heart rate, which adds to the sense of the heart misbehaving. New, marked or persistent rhythm changes always deserve a check from your GP — both for reassurance and to rule out other causes.
- Hot flushes. A flush is not a faulty thermostat — it’s the brain’s alarm. When the brain is short of fuel, the temperature-control centre that sits right beside its stress circuitry becomes oversensitive and misreads ordinary warmth as overheating, so it dumps heat fast: blood vessels open, you flush, you sweat. The trigger is usually a small surge of adrenaline or a dip in blood sugar, which is why flushes cluster around stress, after sugar, and in the small hours. Steady the fuel and stress side and they usually ease — they’re a signal, not a sentence.
- Insomnia. Cortisol is meant to be at its lowest at night so you can sleep. In a stalled Energy Shift it does the reverse, spiking in the early hours — usually as blood sugar dips around 3am — and that surge snaps you awake and leaves you alert when you should be drifting. It’s why menopausal insomnia so often has that exact signature: falling asleep fine, then wide awake at 3 or 4.
- Lethargy. This is the daytime face of the fuel problem. With brain and muscles caught between a glucose supply that’s faltering and a ketone system that hasn’t taken over, there isn’t enough steady energy to draw on — so everything feels heavier and slower, and effort that used to be automatic now takes visible will.
- Night sweats. Night sweats are the same vasomotor surge arriving overnight. Blood sugar dips in the early hours, the brain reads the dip as a threat, and the stress response fires — waking you hot, drenched and then wired, classically around 3am. Because the real trigger is the overnight blood-sugar and cortisol rhythm, what you eat in the evening and how stable your blood sugar is through the night make a genuine difference.
- Palpitations. The adrenaline released as part of the fuel-crisis stress response acts directly on the heart, making it pound, race or seem to skip. It often arrives with a flush, with a blood-sugar dip, or from nowhere at night. Unsettling, and always worth mentioning to your GP for reassurance — but in this context it’s usually the heart responding to a stress signal rather than a heart problem.
- Sleep — broken and restless. Even short of full insomnia, sleep turns lighter and more fragmented. The same blood-sugar dips and cortisol blips ripple through the night, nudging you out of the deep stages, while falling progesterone — which is naturally calming and sleep-promoting — removes some of the body’s own support. You may not wake fully, but you wake unrefreshed.
- Tingling in the hands or feet. Unstable nerve signalling during the energy shift — and the effect of swinging oestrogen on the nerves themselves — can produce pins, needles or a faint buzzing in the hands and feet, coming and going with the other energy symptoms. But tingling has other important causes too, so don’t assume it’s hormonal — other causes include low vitamin B12. It’s worth asking your GP for a simple B12 check rather than assuming it’s hormonal.
- Weight gain around the middle. This is the one women find most unfair, because it happens without eating more. Persistently high insulin tells the body to store fat rather than burn it, and cortisol from the stress response steers that storage to the abdomen, where fat cells are most cortisol-sensitive. Falling oestrogen shifts fat from hips to waist on top of that. It’s a signalling problem — which is why eating less and exercising harder so often fails to move it.
Late perimenopause and menopause: the tissues can’t make enough oestrogen locally – the Oestrogen Shift
By this stage your periods are widely spaced or have stopped, and you’re at or near menopause itself. The dominant oestrogen “deficiency story” misses a crucial adaptation to the decline in ovarian oestrogen: after the ovaries retire, each tissue is designed to make its own oestrogen and testosterone locally, on site, from a raw material called DHEA (sometimes called the “mother hormone”) that comes from the adrenal glands. DHEA travels through the whole body, and each tissue and organ takes it up to make the oestrogen and testosterone it needs. The monthly ovarian production has stopped; instead, each part of the body makes its own oestrogen on site, as required. This is why some women sail through — their local production keeps the tissues supplied.
The late symptoms appear when the local supply runs short, and it runs short for two linked reasons. First, a stalled Energy Shift makes it worse: the constant cortisol of a switched-on stress response competes with DHEA, and an energy-starved brain eventually struggles to sustain the signal that prompts the adrenals to make it. Second, local production depends on a wide range of micronutrients to keep going. So these are symptoms of blocked local production, not of an ovarian oestrogen deficiency — which is why different women can have very different sets of symptoms, and why they can persist past the final period if the underlying causes aren’t addressed.
- Acne (jawline or adult). With oestrogen low and androgens relatively higher, DHT — the stronger version of testosterone — drives the skin’s oil glands to produce more sebum, and breakouts appear — classically along the jaw, chin and neck rather than the forehead. The blood-sugar swings of the energy shift add fuel, because high insulin further raises androgen activity in the skin.
- Arthritis flares. Oestrogen has an anti-inflammatory role in joint tissue, so losing local supply lifts a brake on inflammation — and existing arthritis can flare. The blood-sugar and insulin swings of the energy shift add systemic inflammation on top, so the two shifts compound each other in the joints.
- Back ache (low). The same blend of tissue-level hormone shortfall, lost muscle support and a fuel-starved, cortisol-braced muscular system tends to settle in the lower back, which carries the most load. Thinning bone and stiffer joints can add to it. It’s a common, non-specific ache that nonetheless traces back to the same roots.
- Bone density — falling. Bone is living tissue, constantly broken down and rebuilt, and oestrogen is the main brake on the breakdown side — much of it made locally in the bone itself. As that supply falls, breakdown outpaces rebuilding and bone is lost, fastest in the few years around the final period. It’s silent, which is the danger — worth monitoring with a DEXA scan rather than waiting for a fracture to reveal it.
- Breasts — loss of fullness. Breast tissue is maintained by oestrogen and progesterone, so as their stimulation fades the glandular tissue shrinks back and is partly replaced by fat — breasts lose some fullness, firmness and shape, and may change size. It’s the mirror image of the breast tenderness of the early stage: then, too much stimulation; now, too little.
- Bruising and feeling accident-prone. Slightly slower coordination means more knocks and stumbles to begin with. Then thinner, oestrogen-depleted skin and more fragile small blood vessels mean those knocks turn into bruises far more easily, and the bruises linger. The two effects compound, so you seem to collect marks you can’t account for.
- Chronic conditions — flares of existing ones. DHEA and oestrogen both help steady the immune system and damp inflammation, so as they fall, conditions that were stable can become more active — autoimmune conditions in particular, but also migraine, eczema or IBS. It’s why so many women feel that “everything flared at once” around this time. The common thread is the loss of these hormones’ calming, regulating influence.
- Coordination — reduced. DHEA acts as a neurosteroid in the brain, involved in motor control and reaction speed — so as it declines, fine coordination and timing can slip a little. Combined with the brain-fuel problems of the energy shift, it can show up as feeling clumsier, mistiming movements, or being a beat slower to react than you expect.
- Dream recall — loss of. Earlier in perimenopause many women have unusually vivid, intense dreams. Later, as DHEA falls and sleep architecture changes, the stable REM sleep that dreaming depends on shrinks — and with it goes dream recall, sometimes to the point of feeling you don’t dream at all. It’s a quiet marker of how far the hormonal and sleep picture has shifted.
- Eyes — dry and itchy. The surface of the eye and the glands that oil the tear film are oestrogen- and androgen-sensitive, so they follow the same logic as everywhere else — less local hormone, less lubrication. The eyes feel gritty, dry and tired, or paradoxically watery as a reflex to the dryness. It’s part of the same tissue picture, not a separate problem.
- Hair — facial, increased. It isn’t that androgens surge — it’s that oestrogen falls faster, so the ratio tips towards the androgens that were always there. Acting through the DHT pathway, that relative shift can bring coarser, darker hair on the chin, upper lip or jaw. The same hormonal tilt that thins hair on the scalp thickens it on the face.
- Hair — in new places. The same relative rise in androgen activity can prompt hair growth where there wasn’t any before — and, conversely, loss from places that had it. It’s the body’s hair pattern slowly resetting to a more androgen-influenced map as oestrogen’s restraining influence fades.
- Hair — thinning (scalp). Scalp hair thins for two reasons at once. Falling oestrogen shortens the hair’s growth phase, and as the balance tips towards androgens, more testosterone is converted to DHT, which gradually miniaturises the follicles at the crown and parting. Low iron, low protein and an under-supported thyroid — all common now — make it worse, which is why hair is often a useful early flag that something systemic needs attention.
- Joint pain and carpal tunnel. Joint linings, tendons and the surrounding connective tissue make and use oestrogen locally; it keeps them lubricated and damps inflammation. As local supply falls, joints stiffen — classically worst first thing in the morning — and ache, and tissues swell enough to compress nerves, which is why carpal tunnel so often appears now. It’s widespread and easily mistaken for the start of arthritis.
- Libido — falling. Desire leans heavily on testosterone, which the body also makes from DHEA — so as that supply falls, libido often falls with it. But it’s rarely only hormones: fatigue, broken sleep, the discomfort of dryness, and the emotional reorientation of this stage all feed in. (Worth knowing that HRT can occasionally lower libido further, by raising the protein that mops up free testosterone — one reason “just take oestrogen” doesn’t always help.)
- Mouth — burning sensation. When the mouth dries and its local hormonal support falls, the sensory nerves of the tongue and mouth lose some of their normal “gating” and start firing abnormally — registering burning, scalding or tingling with nothing there to cause it. With little spare fuel for nerve repair, it can persist. It’s the oral cousin of tinnitus: a sensory nerve, under-supplied, generating its own false signal.
- Muscle cramps. Several threads meet here: falling local hormone support, a tendency to lose magnesium, inflammatory signalling, and a muscular system already short of fuel. Together they leave muscles more excitable and prone to cramping — often in the calves at night. It’s rarely a single cause, which is why it responds best to addressing the whole picture.
- Muscle tension — increased. With little spare fuel to power genuine relaxation, and low DHEA leaving cortisol to keep the muscles braced for a threat that never resolves, many women feel permanently tight — especially across the neck, shoulders and jaw. It’s the muscular signature of a nervous system stuck in alert, and it often drives tension headaches and disturbed sleep.
- Muscle tone — slackening. Maintaining muscle leans on local testosterone made from DHEA, so as that supply falls, muscle becomes harder to build and easier to lose — and can feel softer and weaker on the same activity. It matters beyond appearance: muscle is where you burn glucose, so losing it feeds straight back into the insulin and energy problems of the middle stage.
- Nails — brittle. Nails are built from the same kind of structural protein as skin and hair, and they reflect the same drop in hormonal and nutritional building blocks. They become thinner, peel in layers, ridge and split more easily. Like hair, they’re a visible readout of what the body has to spare for its non-essential tissues.
- Pelvic pain. A combination of DHEA-starved tissue, pelvic-floor muscles that cortisol keeps braced and tight, and too little fuel to let those muscles fully relax can leave the whole pelvic area aching, heavy or tender. It often overlaps with the urinary and sexual symptoms in this stage, because they share the same root — tissue and muscle short of local support in a body stuck on alert.
- Sex — painful. As the vaginal and vulval tissues thin and lose lubrication and stretch — part of what’s now called genitourinary syndrome of menopause — sex can become uncomfortable, burning or frankly painful. It’s a direct consequence of the tissue being starved of local oestrogen, not a psychological problem or “just part of getting older”. Because it’s a supply problem it’s treatable, and worth treating early, before discomfort sets up a cycle of tension and avoidance.
- Skin — dry and wrinkling. Skin relies on local oestrogen to drive collagen, hold water and keep its barrier intact. As local supply falls, collagen is lost — fastest in the first few years around menopause, when a significant proportion can go — and skin becomes thinner, drier and less elastic, so fine lines deepen. It’s the visible, outer version of the tissue-thinning happening everywhere oestrogen is made locally.
- Skin — itchy or crawling (formication). Falling tissue oestrogen leaves skin drier and thinner, and it also affects the sensory nerves within the skin — so as well as itching, some women feel a strange crawling, prickling or “ants under the skin” sensation called formication. It’s the skin’s nerves misfiring as their hormonal support drops, not anything actually on the skin.
- Teeth and gums — aching or bleeding. Gum tissue, the collagen that anchors the teeth, and the jawbone that holds them all depend on local oestrogen. As it falls, gums inflame and bleed more easily, can recede, and the bone beneath thins — so teeth may feel different or slightly loosen. It’s why some women suddenly develop gum problems with no change in how they brush.
- Tinnitus (ringing in the ears). Oestrogen helps protect and steady the auditory nerve and the tiny structures of the inner ear. As local supply thins and the calming, buffering effect of DHEA falls, that system can become “noisy” and generate a ringing, hissing or buzzing that isn’t coming from outside. The energy-shift stress response makes it louder, which is why it so often worsens with poor sleep and tension.
- Urinary leakage. Two changes combine: the urethral lining thins and seals less well, and the pelvic-floor muscles lose tone and bulk as local testosterone and oestrogen fall. Together that weakens bladder control, so leaking with a cough, laugh, sneeze or jump becomes more common. It’s tissue and muscle losing their hormonal support — and it responds to addressing both, not just pelvic-floor exercises alone.
- Urination — frequent, or a UTI-like feeling. The bladder and urethra are built from the same oestrogen-dependent tissue as the vagina, so they thin and turn irritable as local supply falls — bringing urgency, frequency, and a burning “UTI” feeling even when tests show no infection. The thinning also makes genuine infections more likely, which is why recurrent UTIs so often begin around this time.
- Vaginal dryness. The vaginal lining depends on a steady local supply of oestrogen — made on site from DHEA — to stay thick, elastic and moist. As that supply runs short, the tissue thins, loses its folds and produces less lubrication, so it feels dry, tight and easily irritated. Unlike hot flushes, this doesn’t fade with time; it tends to progress if the supply isn’t restored — but it responds well to support and is absolutely not something to simply put up with.
The fourth shift no symptom list shows you: the Emotional Shift
Perimenopause isn’t only physical. Running alongside the two shifts above is a third — a change in how you feel, relate and see yourself —and for many women it’s the most disorienting part of all.
For the whole of the reproductive years, oestrogen (working with oxytocin) ran a social programme: it tuned you to other people’s needs and moods, dialled down your own stress response so you could absorb everyone else’s, and kept you anticipating, smoothing and holding things together — often at your own expense. As oestrogen falls, that programme winds down, and the tuning fades.
From the inside, that can feel like a different woman arriving: less willing to absorb, less able to bite your tongue, suddenly intolerant of things you carried without complaint for years. It often shows up as irritability, anger, anxiety, tearfulness, low mood, a loss of patience or confidence, or a sense of “losing myself”. Some of this overlaps with the Energy Shift — anxiety, for instance, is often the brain registering its own fuel crisis — but a large part of it is something else: a reorientation away from a life organised around connection and belonging, towards one organised around your own purpose and becoming.
Seen that way, the so-called mood swings aren’t simply a malfunction to be medicated or switched off. They’re often information — the growing inability to keep performing invisible labour, or to keep saying “it’s fine” when it isn’t. Many women come through the other side more direct, more themselves, and clearer about what they actually want.
Common emotional changes include:
- Irritability and sudden anger — a falling tolerance for what you used to absorb.
- Anxiety or a new sense of dread — partly the brain’s fuel alarm, partly the loss of oestrogen’s calming effect on the stress response.
- Low mood and tearfulness — as the same hormonal steadying fades.
- Loss of confidence and self-doubt — often sharpest in the disorienting middle stage.
- Overwhelm and mental overload — less capacity to hold everyone else’s needs at once.
- Withdrawing, or needing more solitude — the social programme quietening down.
- A sense of “losing yourself” — which, further through, often becomes a sense of finding yourself.
None of this means difficult feelings should be dismissed or simply endured. Persistent low mood, anxiety that won’t lift, or feeling unable to cope deserve to be taken seriously — please reach out to your GP or another professional for support. The point is that these emotional changes have a logic and a direction, and aren’t a sign that something is fundamentally wrong with you. There’s much more on this in the Emotional Shift.
Why the order of symptoms isn’t random
These three stages aren’t arbitrary — they’re the three shifts arriving in sequence, each setting up the next. Progesterone declines first, so the oestrogen dominance symptoms front-load the start. Then oestrogen falls, and the Energy Shift takes over the middle. Finally, DHEA is suppressed — partly by the constant cortisol of a stalled Energy Shift, partly because a fuel-starved brain can no longer drive the adrenal signal that keeps DHEA flowing — so the tissue-level, oestrogen shift symptoms arrive last, as menopause approaches.
The hopeful part is in this sequence: the drivers are connected and modifiable. Ease the energy crisis and you take pressure off the very system that produces the later symptoms.
Will these symptoms ever go away?
This is the question most women actually want answered, and the usual reply is bleak: live with them, or replace what’s been lost. That answer assumes the symptoms are the missing oestrogen, so without replacement they’re permanent.
The three shifts tell a different story. The symptoms aren’t the fall in hormones itself; they’re transitions that have been blocked — and a block can be removed. A woman still having hot flushes in her seventies isn’t proof that this is for life; more often it’s a sign that an Energy Shift was never completed. Even long-standing symptoms can settle when the underlying driver is addressed.
There’s a real truth in the worry, though: oestrogen is anti-inflammatory and matters in every tissue. The point is that the body is built to keep making it locally, from DHEA, well after the ovaries step back. The work is to support that local production — not to treat the body as permanently depleted.
So this isn’t a life sentence, and it isn’t only a choice between suffering and replacing. When the drivers behind each shift are addressed, symptoms can ease — often within weeks, and often years after a last period.
How I support each shift
This is what follows from everything above: if the symptoms come from blocked transitions, then the work is to unblock them — and that looks different at each stage, because the driver is different. This is the shape of how I work with women; the detail is always tailored to the individual.
Early perimenopause — clearing the excess.
Here the problem is oestrogen running unopposed as progesterone falls away, so the aim is to help the body clear and metabolise that excess oestrogen smoothly. That means supporting the routes oestrogen leaves by — chiefly the liver, which breaks it down, and the gut, which carries it out — so less is recirculated. Smoothing this out takes the edge off the dominance symptoms of this stage.
Middle and late perimenopause — feeding the fuel switch and the local oestrogen supply.
This is where the Energy and Oestrogen shifts take hold, and both respond to nutrition and lifestyle rather than to topping up a single hormone. For the Energy Shift, the key is moving towards a lower-carbohydrate way of eating, so that insulin comes down and the body can start burning fat — which is what produces the ketones the brain now needs as fuel. For the Oestrogen Shift, it means supporting DHEA and its conversion into oestrogen and testosterone inside the tissues, using the specific vitamins, minerals and micronutrients those pathways depend on.
Calming cortisol — because it blocks both.
Running underneath both stages is cortisol. A constantly switched-on stress response stalls the fuel switch and competes with DHEA, so bringing cortisol down — through sleep, nervous-system support and steadier blood sugar — is part of the work at every stage.
This approach supports the shifts your body is already trying to make, so the symptoms have less reason to persist. What it looks like for you depends on your stage, your history and your biology — which is what a consultation is for.
Why HRT isn’t always the answer
Perimenopause can be such a rollercoaster, with so many potential symptoms, that there’s a strong narrative that almost any symptom in a woman between about 40 and 60 must be perimenopause or menopause — and that the answer is HRT. But topping up oestrogen is not always the fix.
In the earlier part of perimenopause, the symptoms are driven by oestrogen excess rather than low levels: oestrogen is high and unopposed while progesterone falls away. Giving more oestrogen via HRT to a woman who is already oestrogen-dominant can deepen the dominance symptoms — including heavy, or unpredictable intermittent, bleeding from too much oestrogen.
My approach identifies which stage of perimenopause you’re in and applies the ideal support for that stage, so that HRT becomes optional, and control of your health and your future is in your hands.
