Perimenopause is the hormonal transition that occurs before menopause, often starting in a woman’s 40s. During this time, oestrogen and progesterone fluctuate, leading to physical, emotional, and cognitive changes.

Understanding what’s happening, and how to support your body can significantly reduce symptoms and improve quality of life.

What Happens to the Body During Perimenopause?

During perimenopause, hormone levels fluctuate unpredictably, affecting periods, mood, sleep, metabolism, and stress response. These changes are normal and can last several years before menopause begins.

Common Perimenopause Symptoms After 40

The most common perimenopause symptoms include:

• Irregular, heavier, or skipped periods
• Hot flushes and night sweats
• Anxiety, low mood, or irritability
• Poor sleep or early waking
• Brain fog and memory problems
• Weight gain around the abdomen
• Fatigue and low energy

Symptoms can vary month to month and person to person.

When Does Perimenopause Start?

Perimenopause usually starts between ages 40 and 45, but can begin in the late 30s. It ends when menopause begins, defined as 12 consecutive months without a period.

Key Changes During Perimenopause After 40...

Hormonal Changes During Perimenopause

Oestrogen rises and falls unpredictably during perimenopause, while progesterone steadily declines. This imbalance can trigger mood changes, anxiety, sleep problems, and heavier periods.

Support tip: Prioritise regular sleep, balanced meals, and stress reduction to stabilise hormone response.

Anxiety During Perimenopause

Why does perimenopause cause anxiety?
Hormonal fluctuations affect neurotransmitters like serotonin and GABA, increasing nervous system sensitivity and stress reactivity.

Support strategies:

• Slow breathing and grounding exercises
• Gentle movement (walking, yoga)
• Reducing caffeine and overstimulation

Sleep Problems in Perimenopause

Perimenopause sleep problems are linked to declining progesterone and rising cortisol. This can cause difficulty falling asleep, night waking, or early waking.

Support tip: A consistent bedtime routine and calming evening rituals can improve sleep quality.

Weight Gain During Perimenopause

Perimenopause weight gain is caused by hormonal changes, reduced muscle mass, and insulin resistance - not lack of willpower.

Supportive approaches:

• Strength training 2–3 times per week
• Protein-rich, blood-sugar-stable meals
• Avoiding restrictive dieting

Brain Fog During Perimenopause

Perimenopause brain fog occurs because oestrogen supports memory, focus, and cognitive processing. Fluctuations can temporarily affect concentration.

Support tip: Sleep, hydration, omega-3 fats, and reduced multitasking help protect cognitive function.

How to Support Your Body During Perimenopause

1. Stabilise Blood Sugar: Eat regular meals with protein, fibre, and healthy fats to reduce hormonal stress.
2. Regulate the Nervous System: Daily calming practices lower cortisol and improve hormone balance.
3. Build Gentle Daily Rituals: Consistent routines signal safety to the body during hormonal change. Try our MNPS/1 Candle as part of your night-time routine.
4. Prioritise Rest and Recovery: Recovery becomes more important than intensity after 40.

Best Diet for Perimenopause

A perimenopause-supportive diet includes:

• Protein at every meal
• Healthy fats for hormone production
• Fibre for gut and oestrogen balance
• Magnesium-rich foods for sleep and stress

This supports energy, mood, and weight stability.

Is Perimenopause a Medical Problem?

No. Perimenopause is a natural life stage, not a disease. Symptoms occur because the body is adapting to hormonal change and often improve with appropriate lifestyle support.

Final Thoughts: Navigating Perimenopause After 40

Perimenopause is not something to “push through.”
It’s a biological transition that requires kinder support, not more pressure.

When you respond to your body with nourishment, rest, and regulation, perimenopause becomes a period of recalibration - not decline.
