Section 1 of 10
Prevalence & Demographics
How many women. How early it starts. How little most of us knew.
1.1 billion
Women worldwide will be postmenopausal by 2025 — projected to reach 1.2 billion by 2030.
13 million
Women in the UK are currently perimenopausal or menopausal — one-third of the female population.
6,000
Women reach menopause every single day in the US — 1.3 million per year.
80–96%
Of women experience menopausal symptoms. Up to 96% will feel this in some form.
Age 45–55
The typical window for natural menopause, with an average age of 51. But perimenopause can begin in the mid-30s — years before most women expect it.
26%
Of all women and girls globally were aged 50+ in 2021, up from 22% a decade earlier. This demographic is growing fast — and still underserved.

Symptoms
The things nobody warned you about — and the numbers that prove you're not making it up.
75–80%
of women experience hot flashes during the menopause transition. Three out of four. This isn't rare. This is the norm.
75%
Experience vaginal dryness. Most never mention it to their doctor.
60%
Of women report cognitive difficulties — “brain fog” — during the menopause transition. Prevalence rises from 31% premenopausal to 44% in early perimenopause.
56%
Of perimenopausal women sleep less than 7 hours on average, compared to 32.5% of premenopausal women.
65%

70%
Of women gain up to 1.5 pounds per year during the menopause transition.
50%

How Long It Lasts
Spoiler: longer than anyone told you.
7.4 years
The median duration of frequent hot flashes and night sweats. Not months. Years.
4–10 years
How long perimenopause typically lasts. The average is 4 years, but some women experience symptoms for up to a decade — or longer.
11.8 years
If hot flashes begin in premenopause or early perimenopause, they can last over 11 years — with 9.4 years persisting after the final period.
| Ethnicity | Median Duration of Vasomotor Symptoms | Source |
|---|---|---|
| 10.1 yrs | African American women | SWAN Study |
| 8.9 yrs | Hispanic women | SWAN Study |
| 6.5 yrs | Non-Hispanic white women | SWAN Study |

| 4.8 yrs | Japanese women | SWAN Study |
Section 4 of 10
Mental Health
The part that almost never gets discussed. And the part that can feel the most dangerous.
7x
A seven-fold increased risk of suicidal ideation was found in perimenopausal women — independent of existing mood or anxiety disorders.
Women with no prior history of depression are 2–4 times more likely to experience a depressive episode during perimenopause. This isn't “just feeling down.” This is clinical.
2–5x
Increased risk of a major depressive episode during perimenopause compared to premenopause.
1 in 3
Women met the criteria for panic disorder during perimenopause and received no diagnosis or treatment.
33%
Of women feel hopeless about menopause — 50% higher among women aged 40–49 versus those over 50.
58%
Greater risk of another depressive episode during perimenopause for women with a history of depression during prior hormonal windows (postpartum, PMS).
Section 5 of 10
The ADHD Connection
When your hormones shift and your coping strategies suddenly stop working — there might be a reason nobody mentioned.
94%
Of women with ADHD reported that their symptoms grew more severe during perimenopause and menopause.
43%
Of women with ADHD were first diagnosed between ages 41 and 50 — during perimenopause.
54%
Of women with ADHD experience severe perimenopausal symptoms, versus 30% of women without ADHD.
70%
Of women with ADHD said it had a “life-altering” impact in their 40s and 50s.
Ages 35–39
The age range where the gap in severe symptoms between women with and without ADHD is most pronounced — suggesting perimenopause may begin earlier in women with ADHD.
Section 6 of 10
Workplace Impact
The career cost nobody's calculating into their benefits package.
333,000
Estimated number of women in the UK who have left a job because of menopause symptoms.

14%
Of UK women are currently taking HRT. A 22% increase from the previous year — but still a small fraction.

70%
Of women using supplements or herbal remedies for menopause do not tell their healthcare provider.
29% → 11%
HRT uptake in the UK fell by more than half between 2001 and 2005 following the Women's Health Initiative findings. It's only now starting to recover.
Section 9 of 10
The Knowledge Gap
