Menopause Explained

Understanding Menopause

Menopause is a natural stage of life that marks the end of reproductive years.

It is generally defined as having gone 12 consecutive months without a menstrual period and occurs because the ovaries gradually reduce their production of hormones such as oestrogen and progesterone.

While menopause is a normal biological transition, the experience can vary significantly from one woman to another.

Some women move through this stage with relatively few changes, while others notice shifts in sleep, energy, mood, body composition, temperature regulation, cognition and overall wellbeing.

Understanding what is happening within the body can help make these changes feel less confusing and support more informed health decisions.

Menopause is one stage within the broader hormonal transition many women experience during midlife. For a wider overview of how hormones interact with multiple body systems, explore our guide to Understanding Midlife Hormonal Changes.

What Happens During Menopause?

Throughout the reproductive years, the ovaries produce hormones that influence far more than the menstrual cycle.

As ovarian hormone production declines, the body adapts to a new hormonal environment.

This adjustment process can contribute to a wide range of experiences and symptoms, some of which may begin during perimenopause and continue into menopause itself.

If you are still experiencing menstrual periods, even if they have become irregular, you may find our Perimenopause Explained guide helpful for understanding the transition leading up to menopause.

Common Experiences During Menopause

Not every woman experiences all of these changes, and the intensity can vary considerably.

Why Do Hot Flushes and Night Sweats Occur?

One of the most recognised features of menopause is the occurrence of hot flushes and night sweats.

Researchers believe these experiences are linked to changes within the hypothalamus, a region of the brain involved in regulating body temperature.

As hormone patterns change, the body's internal thermostat may become more sensitive, causing the body to trigger cooling responses such as sweating even when only small temperature changes occur.

For some women these episodes are occasional, while for others they may occur multiple times throughout the day or night.

Menopause and Sleep

Sleep changes are among the most commonly reported concerns during menopause.

Poor sleep can then influence energy, concentration, emotional wellbeing and resilience during the day.

For a deeper exploration, see our guide on Hormones & Sleep.

Menopause and Brain Function

Many women describe changes in memory, concentration and mental clarity during menopause.

Some women refer to this experience as "brain fog".

Research suggests hormonal changes may influence brain function, although factors such as sleep quality, stress levels and overall health may also contribute.

Menopause and Musculoskeletal Health

Hormonal changes can coincide with changes in muscles, joints and connective tissues.

Regular movement, strength training and maintaining overall physical activity may support musculoskeletal health during this stage of life.

Menopause and Long-Term Health

Menopause can also coincide with changes that may influence long-term wellbeing.

This does not mean problems are inevitable. Rather, menopause can provide an opportunity to review lifestyle habits and focus on strategies that support long-term health and resilience.

Once menopause has occurred, many women begin focusing on long-term wellbeing, healthy ageing and maintaining vitality in the decades ahead. Learn more in our Post-Menopause & Healthy Ageing guide.

A Whole-Person Perspective on Menopause

Menopause affects far more than reproductive hormones alone.

Sleep, stress, movement, nutrition, gut health, environmental factors, social connection and overall lifestyle may all influence how a woman experiences this transition.

Many women find that understanding these interconnected factors helps them feel more empowered and better equipped to navigate this stage of life.

Frequently Asked Questions About Menopause

What is the difference between perimenopause and menopause?

Perimenopause refers to the transition leading up to menopause when hormone patterns begin changing and menstrual cycles may become irregular. Menopause is reached after 12 consecutive months without a menstrual period.

What age does menopause usually occur?

Most women experience menopause between the ages of 45 and 55, although timing can vary significantly between individuals.

How long do menopause symptoms last?

Experiences vary considerably. Some women notice changes for a relatively short period, while others experience symptoms for several years.

Can menopause affect sleep?

Many women report sleep changes during menopause. A range of factors may contribute, including temperature regulation changes, stress levels, lifestyle factors and age-related changes in sleep patterns.

Can menopause affect joint comfort?

Some women report changes in joint comfort, mobility and recovery during menopause. Multiple factors may contribute, including activity levels, muscle mass, ageing and hormonal changes.

Is menopause a normal part of ageing?

Yes. Menopause is a natural biological stage of life that marks the end of reproductive years and forms part of the normal ageing process for women.
