Peri/menopause can be confusing and exhausting. It doesn't need to be.
A peri/menopausal woman is not a faulty younger woman; she is running a completely different, highly intelligent biological design - and this design needs a different approach.
You've been told the empty tank story: your ovaries stop, oestrogen falls and your body slowly winds down. That's myth, not biology.
Lower oestrogen is where your body was designed to arrive, and the change is built for resilience and a longer health span
It's a natural transition
Your hormones run an ancient programme, 1.5 million years in the making, written for Original Eve. She lived on whole foods, deep circadian sleep, natural movement and close community. In this world, this transition was simply the next stage of life.
It's mismatched to a modern lifestyle
Today we Burnt-out Eves run the same programme on processed food, chronic stress, too little sleep and constant pressure. Hot flushes, sleepless nights, anxiety and stubborn weight gain are your body's distress signals from that mismatch.
There is a clear way through
If the mismatch is the problem, closing it is the answer. It isn't oestrogen that needs replacing, it's a nourished life. Change the conditions and symptoms can resolve, whether you go through the transition naturally or come off HRT with support.
Perimenopause takes you through 2 hormonal phases and 4 metabolic shifts.
That's why everything changes—from how you sleep to how you think.
How is your nutrition, blood sugar, stress, sleep, and liver detoxification?
These are the foundations on which your transition has to operate.
When these foundations fail, your symptoms flare—and no amount of external HRT can patch over those broken roots.
1 of 4Early perimenopause
Progesterone shift
Oestrogen spikes up to 3 x higher and progesterone crashes as ovulation becomes unreliable. It starts in your late 30s or early 40s, while your periods are regular and get shorter.
- Heavy and flooding periods
- Rage and irritability
- Breast tenderness and bloating
- Cyclical anxiety and 3am waking
2 of 4Late perimenopause and menopause
Energy shift
As ovarian oestrogen falls, your brain has to switch fuel from glucose to ketones. A modern, carb-heavy diet keeps that switch from happening.
- Hot flushes and night sweats
- Brain fog
- Palpitations, anxiety and low mood
- Fatigue and weight gain
3 of 4Late perimenopause and menopause
Oestrogen shift
Oestrogen production moves from the ovaries to organs - brain, bones, vaginal tissues - built from adrenal DHEA. Each organ needs the right nutrients to make oestrogen and testosterone.
- Joint pain and morning stiffness
- Thinning, crepey skin
- Vaginal dryness and recurrent UTIs
- Losing muscle despite training
4 of 4Late perimenopause and menopause
Identity shift
Your nervous system reorganises. As oxytocin fades and cortisol rules, the old way of coping, absorbing everyone else’s strain, stops working, and something freer can take its place.
- Anger that is hard to place
- Losing patience with old roles
- Withdrawal that surprises you
- Carrying everything, and no longer willing to
Adapting to the changes that peri/menopause brings can be hard, but this is where I am trained to help you
Hi, I'm Sandra Ishkanes
Functional medicine menopause specialist
BSc · MA · DipION · ANP MEMBER
I have a degree in molecular biology, clinical training in functional medicine and I am an expert in resolving the root causes of peri/menopausal health issues.
Why choose a functional medicine approach to peri/menopause with me?
Standard medicine treats symptoms. Functional Medicine is a science-based approach to health that looks for the root causes of your symptoms, such as blood sugar, stress, gut health and sleep. These are the exact factors that change as your hormones do.
80markers analysed in your first blood panel
My blood test panel includes oestrogen, progesterone, FSH, LH, prolactin, cortisol, 5 thyroid markers, 4 iron markers, 5 liver markers, cholesterol, blood sugar, red and white blood cells, vitamin D, B12, folate, magnesium, and more, together, as one picture.
Symptoms and conditions I work with every day
Most women come to me with several at once, often treated separately by different specialists, with no one connecting the dots. Seen together, they tell a story about what your body is going through.
Early perimenopause
- Heavy periods, flooding and clotsHeavy and flooding periods in early perimenopause occur because anovulatory cycles allow the womb lining – the endometrium – to thicken without progesterone to provide the scaffolding. When that lining sheds as a period, the bleed is heavier, longer and more chaotic. The solution is to remove excess oestrogen via liver detoxification.
- AnxietyAnxiety and worsening ADHD in early perimenopause are driven by a biochemical traffic jam. As progesterone drops and heavy bleeding drains iron, chaotic oestrogen spikes actively suppress the COMT enzyme, trapping adrenaline in your body. This hormonal bottleneck happens to everyone, but having a genetic Slow COMT variant makes it significantly worse by amplifying the panic and shattering focus. You can clear this backlog and reclaim calm by using magnesium, choline and targeted dietary shifts.
- BloatingBloating appears because the gut is exquisitely sensitive to progesterone loss – as anovulatory cycles increase, gut transit slows, gas accumulates, and mast cell reactivity in the gut wall drives histamine-mediated distension. This hormonal gut disruption responds to addressing excess oestrogen to balance progesterone loss.
- Sore breastsBreast tenderness in early perimenopause is caused by the Progesterone Shift: oestrogen continues stimulating breast tissue while progesterone – normally produced after ovulation to moderate that effect – is absent or insufficient, producing swelling, heaviness and sensitivity worst in the week before your period. Addressing the oestrogen dominance through the Progesterone Shift protocol is what resolves it.
- Itchy skinExcess oestrogen releases excess histamine into your tissues. This sudden histamine spike can cause unexplained itching, flushing and hives. Some women experience a prickly sensation, “pins and needles”, or a feeling like something is crawling on the skin rather than a standard itch.
Complex conditions
- FibroidsFibroids feed on oestrogen — and early perimenopause is when oestrogen runs highest and least opposed. As ovulation skips and progesterone crashes (the Progesterone Shift), oestrogen dominates, and the growth it drives is amplified by anything that raises oxidative stress in the uterus or slows your ability to clear oestrogen: insulin, alcohol, a struggling gut, low vitamin D and the Slow COMT gene. Most of those drivers are identifiable and, in large part, addressable.
- EndometriosisWhen two oestrogen-driven conditions meet, the result is not relief — it is amplification. The Progesterone Shift lands on lesion tissue that already produces its own oestrogen via local aromatase and is structurally resistant to progesterone — a double hit to the same imbalanced hormonal axis. For many women, perimenopause is the hardest chapter of the disease, and navigating it requires clinical support that addresses the hormonal terrain.
- AdenomyosisEarly perimenopause worsens adenomyosis because erratic hormonal fluctuations trigger high spikes in oestrogen without enough progesterone to balance it. This “oestrogen dominance” directly stimulates the displaced endometrial tissue inside the uterine wall, causing it to swell and inflame. Combined with the increasingly irregular, heavier and more frequent menstrual cycles typical of early perimenopause, the uterus is forced to contract against stiff, inflamed muscle tissue, leading to significantly worse pelvic pain, debilitating cramps and severe bleeding.
- PCOSWhat was once an evolutionary survival benefit is now causing havoc due to high testosterone driven by sugar and insulin. Intermittent periods, acne, weight gain and unwanted hair can improve in early perimenopause, but get worse in late perimenopause when dropping oestrogen magnifies insulin resistance.
- PMDDPremenstrual Dysphoric Disorder causes severe irritability, depression or anxiety in the week or two before the menstrual cycle starts. Because women with PMDD are hyper-sensitive to normal hormonal shifts, the unpredictable midlife hormonal rollercoaster triggers severe anxiety, rage and depressive symptoms more frequently, stretching the suffering across unpredictable parts of the cycle.
Late perimenopause and menopause
- Brain fogBrain fog — losing words, forgetting why you walked into a room, reading the same line three times — has a specific, physical cause: the brain running short of the energy it needs for you to think clearly. As ovarian oestrogen declines, it takes with it the ability to use sugar for energy — if you’re not burning fat, you will experience a severe energy deficiency.
- Fatigue and energy crashes
- Anxiety and mood swings
- 3am waking
- Hot flushes and night sweatsNot every woman gets hot flushes, even with the same fall in oestrogen — and that is the clue to what actually drives them. A flush is produced by the brain’s temperature centre, but what sets that centre firing is the shift in oestrogen together with the brain’s fuel and stress state. Here is the science underneath hot flushes, and what brings them down.
- Weight gain and meno-belly
- Joint painWaking up with stiff, painful joints in menopause? Discover the real root cause of menopause joint stiffness and how to reverse it without an HRT prescription.
- Vaginal dryness and recurrent UTIsGenitourinary Syndrome of Menopause (GSM) isn’t a hormonal deficiency — it’s a progressive tissue and circulatory breakdown affecting up to 84% of women. By understanding how to protect the microbiome and intracrinology — how oestrogen can be made in the vaginal tissues — you can activate the body’s natural adrenal pathways to heal pelvic tissue from the inside out, completely independent of hormone prescriptions.
