Onset of menopause
In Europe, menopause occurs on average at around 51, but the individual range is wide and it is preceded by several years of perimenopause. If your cycle changes and symptoms appear after forty, this is not unusual – discuss them with your gynaecologist.
Have vasomotor symptoms
Vasomotor symptoms – hot flushes and night sweats – affect most women during the transition, and for some they last for years. Layered, lighter clothing, a cooler bedroom, less alcohol and, if symptoms are severe, a conversation with your doctor about treatment options can help.
For effective HRT intervention
According to current expert guidance, the benefit–risk balance of hormone therapy is most favourable when it is started within 10 years of menopause or before age 60. If you are considering it, discuss your symptoms and medical history with your gynaecologist in good time.
Menopause is defined as 12 months without a period. On average it begins at the age of 51, with the perimenopausal phase starting 4–10 years earlier. The main change: ovarian production of oestrogen and progesterone stops. The result isn't just "the end of fertility" — it's a systemic hormonal reset with far-reaching effects.
Oestrogen isn't just a reproductive hormone. It has neuroprotective effects — regulating serotonin, dopamine and acetylcholine signalling. The brain's oestrogen receptors sit in the hippocampus, prefrontal cortex and amygdala. Falling oestrogen = cognitive changes (brain fog, memory problems) and a higher risk of Alzheimer's.
What happens during menopause
The fall in oestrogen leads to: vasomotor symptoms (hot flushes, night sweats — affecting 80% of women), urogenital atrophy (dryness, dyspareunia, recurrent UTIs), osteoporosis (oestrogen protects bone density), cardiovascular risk (oestrogen has a cardioprotective effect), cognitive changes, poorer sleep (progesterone has a sedative effect; its absence = insomnia) and metabolic changes (increase in visceral fat, insulin resistance).
Symptoms and their biological cause
Hot flushes: dysregulated thermoregulation in the hypothalamus (oestrogen stabilises the thermostatic set point). Insomnia: absence of progesterone (GABA-agonist effect), disrupted melatonin rhythm. Brain fog: falling oestrogen reduces cerebral blood flow and the brain's glucose metabolism. Depression/anxiety: oestrogen modulates the serotonin system. Joint pain (arthralgia): oestrogen has an anti-inflammatory effect.
HRT — what current science says
The WHI study (2002) caused panic around HRT — but its design was flawed (later start, synthetic hormones, oral administration). Current evidence (Menopause Society 2022): bioidentical HRT started within 10 years of menopause (the Window of Opportunity) is safe for healthy women and beneficial for the cardiovascular, cognitive and skeletal systems. Transdermal oestrogens (patches, gel) carry no increased risk of thromboembolism, unlike oral ones.
Biohacking menopause — the protocol
Phytoestrogens: soy isoflavones (genistein, daidzein), flax lignans — weak oestrogenic effects that reduce hot flushes in some women. Magnesium bisglycinate (400 mg) — sleep, muscle cramps. Omega-3 — anti-inflammatory, cardioprotective. Vitamin D3+K2 — bones. Strength training is key — it protects bone and muscle mass and improves insulin sensitivity. Collagen (10 g/day) — urogenital and joint atrophy. A low-carbohydrate diet or time-restricted eating — metabolic adaptation. Ashwagandha — cortisol, sleep, energy.
