Menopause: Complete Guide to Symptoms & Treatment

Menopause is the day that marks 12 consecutive months without a period — a single calendar date, medically speaking. What most people call "menopause" is actually the entire hormonal transition around it, which can last 8 years or more.

Physiologically, menopause happens when your ovaries have exhausted their follicular reserve. Production of the two main reproductive hormones — estrogen and progesterone — falls dramatically, which is what drives the symptoms. It is not a disease, not a deficiency to "cure," and not something to dread. It is a biological stage every woman who lives long enough reaches.

The average age is 51, with a typical range of 40 to 58. Genetics is the strongest predictor — your mother's age at menopause is a decent guide. Smoking advances it by 1-2 years. Surgical removal of the ovaries causes it instantly, often with more severe symptoms because the transition is sudden.

The transition is usually split into three stages:

1. Perimenopause — The transition phase, lasting 4 to 10 years before the final period. Estrogen fluctuates wildly and progesterone drops first. Cycles become irregular. Most of the symptoms people associate with "menopause" actually happen here. Starts on average at 45-47, sometimes earlier.

2. Menopause — The single day marking 12 months since your last period. Estrogen and progesterone have settled at a low baseline. Symptoms often peak in the 1-2 years around this point.

3. Postmenopause — Every year after that day. For most women, symptoms gradually ease over 1-3 years. Long-term health priorities shift toward bone, cardiovascular, and cognitive protection.

The average age is 51, but the range is wide:

• Premature menopause (before 40) — about 1% of women. Usually needs specialist assessment and hormone therapy at least until the average menopause age, for long-term bone and cardiovascular protection.
• Early menopause (40-45) — about 5% of women. Often benefits from HRT.
• Typical menopause (45-55) — about 85% of women. Median age 51.
• Late menopause (after 55) — about 5% of women. Slightly reduced osteoporosis risk; slightly higher hormone-related cancer risk.

Chemotherapy, pelvic radiation, and surgical removal of both ovaries all cause immediate menopause — often with more intense symptoms because the transition is abrupt rather than gradual.

Most women experience a handful of these, not all. Tracking the top three is more useful than worrying about the list:

1. Hot flashes and night sweats — up to 75% of women, median duration about 7 years.
2. Sleep disruption — waking at 3-5am and not getting back to sleep.
3. Anxiety, mood swings, depression — up to 51% of women in perimenopause report new anxiety.
4. Morning anxiety and cortisol dysregulation — the wired-but-tired feeling.
5. Brain fog — word-finding trouble, memory lapses, difficulty concentrating.
6. Weight gain, especially belly fat — not from eating more, but from fat redistribution and muscle loss.
7. Joint aches and stiffness — often the first symptom women notice, often blamed on age.
8. Vaginal dryness and genitourinary symptoms — painful sex, recurrent UTIs, urinary urgency.
9. Skin and hair changes — thinner, drier skin; hair shedding.
10. Libido changes — usually downward, sometimes multifactorial.
11. Heart palpitations — benign in most cases but deserve one check.
12. Irregular periods — the earliest and most reliable sign of perimenopause.

Treatment is not about curing menopause — it is about reducing symptom burden and protecting long-term health. The main options, ranked by evidence:

Hormone replacement therapy (HRT) — the most effective treatment for moderate-to-severe symptoms. Reduces hot flashes by 75-90%, improves sleep, mood, bone density, and genitourinary symptoms. Best evidence for women under 60 or within 10 years of their final period — the "window of opportunity."

Non-hormonal medications — when HRT is not suitable or not enough:

• Low-dose SSRIs and SNRIs (escitalopram, venlafaxine, paroxetine) for hot flashes and mood
• Fezolinetant (Veozah) — FDA-approved 2023, targets NKB neurons directly
• Gabapentin when night sweats dominate
• Localised vaginal estrogen for genitourinary symptoms — almost no systemic risk, safe for most women

Cognitive behavioural therapy (CBT) for menopause — specifically adapted programmes reduce distress from hot flashes, sleep, and mood by up to 70%. First-line non-hormonal recommendation from NICE.

Lifestyle changes with real evidence — strength training twice weekly for bones and metabolism, fixed wake time, 20-30g protein per meal, 150+ minutes of moderate cardio weekly, delaying caffeine 60-90 minutes after waking.

The first 5 years after menopause are when women lose the most bone density and see the sharpest shifts in cardiovascular and metabolic risk. Acting during perimenopause and early postmenopause shifts the trajectory more than acting later.

• Bone health — osteoporosis risk rises sharply. Baseline DEXA scan around menopause, calcium and vitamin D, weight-bearing and resistance exercise. HRT is bone-protective.
• Cardiovascular health — estrogen was mildly protective; that protection goes. Blood pressure, lipids, and visceral fat matter more now. HRT started within the window is generally cardioprotective.
• Cognitive health — risk of Alzheimer's is twice as high in women as in men, and the menopause transition seems to matter. Sleep, movement, HRT in some cases all figure in.
• Metabolic health — insulin resistance often worsens; diet and strength training push back.
• Pelvic floor — estrogen decline weakens tissues. Pelvic floor physiotherapy is under-prescribed and very effective.

Speak to a clinician if:

• Symptoms affect your quality of life — sleep, relationships, work performance
• You reach menopause before 45, especially before 40 (needs specialist assessment)
• You bleed after 12 months without a period (always investigate)
• You want to discuss HRT or other treatment
• You have new heart palpitations, severe mood changes, or persistent pelvic pain

Prepare with 4 weeks of symptom tracking — frequency, severity, triggers — and bring your priorities written down. Clinicians work faster with data than with "I'm not sure, everything is a bit off."
