Start here: understanding perimenopause

If you have been feeling a little off lately, more tired, more anxious, struggling with sleep, or simply not quite like yourself, you are not imagining it.

The basics

What is perimenopause?

Perimenopause is the phase leading up to menopause, during which key hormones, particularly oestrogen and progesterone, begin to fluctuate rather than decline in a steady, predictable way. These fluctuations can affect sleep, mood, metabolism, temperature regulation, and cognitive function. This is why the symptoms of perimenopause can feel so wide-ranging and inconsistent.

Menopause itself is defined as the point when 12 consecutive months have passed without a period. Perimenopause is everything that leads up to that point and it can last anywhere from a few years to over a decade.

Perimenopause commonly begins in the late 30s to mid-40s, and the earliest signs are often not period-related at all.

Many women first notice changes in their sleep quality, their stress tolerance, or their mood, sometimes years before their cycle changes at all. Hormonal variability is one of the hallmarks of this transition. Levels can rise and fall unpredictably from week to week, which explains why symptoms may appear suddenly, ease off, and then return again.

Common symptoms

What perimenopause can feel like

Because hormones interact with so many systems in the body, symptoms can feel very different from one woman to the next.

Sleep and energy

  • ✓Difficulty staying asleep or waking early
  • ✓Night sweats
  • ✓Persistent fatigue or energy dips

Mood and mind

  • ✓Anxiety or low mood
  • ✓Mood swings or irritability
  • ✓Brain fog or reduced concentration

Body and cycle

  • ✓Irregular or heavier periods
  • ✓Hot flushes or palpitations
  • ✓Weight changes and joint pain

These are biological responses to hormonal change, not a sign that you are not coping.

Practical guidance

What actually helps

There is no single solution, and anyone who tells you otherwise is oversimplifying. Many women see a meaningful difference from a combination of understanding, lifestyle support, and where appropriate, medical guidance.

1

Education and understanding

Knowing the biology behind your symptoms can significantly reduce uncertainty, self-doubt, and self-blame.

2

Sleep and stress support

These are often the first systems to be affected and the most impactful to address early.

3

Nutrition and key nutrients

Magnesium, omega-3 fatty acids, and vitamin D all have good evidence in this area.

4

Movement and light exposure

Both support metabolic health and your circadian rhythm.

5

Medical guidance when needed

This includes an informed conversation about hormone therapy with a doctor who specialises in this area.

You are not alone in this

“Many women spend months, sometimes years, assuming they are simply not managing as well as they used to. In reality their bodies are navigating a significant hormonal transition.”

Perimenopause is not a weakness. It is a natural life stage that deserves proper information and a little more honesty than it usually gets.
