Menopause marks the natural end of the reproductive years, when periods stop permanently and pregnancy is no longer possible.
Clinically, it is diagnosed after 12 consecutive months without a period, when there’s no other medical reason for periods to have stopped.
In the UK, menopause happens on average around age 51, but this varies widely. Importantly, the lead-up phase, called perimenopause can begin years earlier, often in someone’s late 30s to early 40s, and this is when most symptoms appear.
What’s actually happening in the body?
As the ovaries age, levels of oestrogen and progesterone begin to fluctuate and then gradually fall.
These hormones show effects throughout the body, including the brain, heart, bones, and nervous system.
Oestrogen plays a key role in regulating body temperature and supporting brain function, including attention, memory, and processing speed.
As oestrogen levels fluctuate and decline during perimenopause and menopause, it leads to hot flushes and night sweats. These hormonal changes can also affect cognitive function, which is why some people experience “brain fog,” difficulty concentrating, or memory lapses during this time.
Progesterone also declines during the menopausal transition.
This hormone has a calming effect on the nervous system and supports healthy sleep. As progesterone levels fall, the body may become more sensitive to stress and sleep can become disrupted, night sweats can also severely impact sleep quality.
This helps explain why anxiety, poor sleep quality, and insomnia are common during perimenopause and menopause, even in those with no previous history of sleep or anxiety problems.
Oestrogen also helps protect bone density and supports cardiovascular health. After menopause, the risk of osteoporosis (bone thinning and fractures) increases. There is also a gradual rise in cardiovascular disease risk after menopause, making long-term monitoring and preventative healthcare increasingly important.
With nearly 4 million women aged 45–54 currently employed in the UK, this demographic represents a cornerstone of the modern economy.
Furthermore, women over 50 now constitute one of the fastest-growing segments of the entire workforce, making their health and retention a strategic priority for any leadership team.
This demographic typically holds the most institutional knowledge and senior leadership roles.
However, it is also the peak age for perimenopause and menopause, a transition that, without proper support, leads to a significant loss of top-tier talent.
“These are women in the prime of their lives, in their late 40s and 50s, who should be in senior positions, the people who should be the trailblazers and role models for younger people in the workplace.” – (Gender Health Gap 2024)
While every menopausal journey is unique, the hormonal fluctuations of perimenopause and menopause can create a “perfect storm” of symptoms that directly clash with the demands of senior leadership.
And as an employer, it is vital to recognise that symptoms like loss of confidence or memory lapses are not “performance issues,” they are measurable, biochemical responses to a significant physiological transition.
Approximately 1 in 10 women have left a job due to menopause symptoms (Fawcett Society, 2022).
When a senior leader leaves, the cost to the business includes recruitment fees, training & upskilling, and the invaluable loss of mentorship for younger staff.
Research indicates that menopause-related symptoms are a primary driver of absenteeism and “presenteeism” (being at work but unproductive).
The NHS Confederation reports that menopause-related attrition and illness cost the UK economy an estimated £1.5 billion annually (NHS Confederation, 2024).
In the UK, the Equality and Human Rights Commission (EHRC) has issued clear guidance: if menopause symptoms have a long-term and substantial impact on a woman’s ability to carry out normal day-to-day activities, they may be considered a disability under the Equality Act 2010. Failing to provide “reasonable adjustments” can lead to costly employment tribunals.
Education, Clinical Care, Policy & Flexibility are key pillars of a supportive workplace for menopausal individuals.
