What is Perimenopause? Symptoms, Diagnosis, and How to Support Your Body
Many women reach their late 30s or 40s and begin noticing changes in their body that they can’t quite explain. Maybe your sleep has changed, your mood feels different, or your periods have become irregular.
For many women, these changes are part of a natural stage of life called perimenopause.
Understanding what perimenopause is can help you feel less confused and more empowered to support your body during this transition.
What is Perimenopause?
Perimenopause is the phase before menopause when a woman’s hormone levels begin to change. The word literally means “around menopause.”
During this time, the ovaries gradually produce less of the hormones that regulate the menstrual cycle, particularly oestrogen and progesterone.
Perimenopause can begin several years before menopause, often in a woman’s 40s, although some women notice symptoms earlier. It continues until menopause, which is defined as 12 consecutive months without a period.
Hormone levels can fluctuate significantly during this time, which is why symptoms can appear suddenly and sometimes feel unpredictable.
Common Symptoms of Perimenopause
Because hormones affect many systems in the body, perimenopause symptoms can vary widely from woman to woman.
Some of the most common symptoms include:
Changes to your menstrual cycle
- Irregular periods
- Heavier or lighter bleeding
- Shorter or longer cycles
Sleep problems
- Difficulty falling asleep
- Waking during the night
- Feeling tired during the day
Mood changes
- Anxiety
- Irritability
- Low mood
- Feeling more emotional than usual
Physical symptoms
- Hot flushes
- Night sweats
- Brain fog
- Headaches
- Joint aches
- Weight changes
Some women experience only mild symptoms, while others find the changes more disruptive.
How is Perimenopause Diagnosed?
Unlike some medical conditions, there is no single test that definitively diagnoses perimenopause.
Doctors usually diagnose it based on:
- Age
- Symptoms
- Changes in your menstrual cycle
Blood tests may sometimes be used to measure hormone levels, but hormones fluctuate frequently during perimenopause, so the results don’t always give a clear answer.
If symptoms are affecting your quality of life, it’s important to speak with a healthcare professional who can discuss possible treatments and support options.
How Can We Support Our Bodies During Perimenopause?
Although we can’t stop the hormonal changes of perimenopause, there are ways we can support our bodies and make this transition easier.
This is where self-care becomes incredibly important.
Prioritise Sleep
Sleep can become disrupted during perimenopause, but creating a calming bedtime routine can help.
Try to:
- Keep a consistent sleep schedule
- Reduce screen time before bed
- Create a relaxing evening routine
Good sleep supports hormone balance, mood, and overall wellbeing.
Manage Stress
Hormonal changes can make your body more sensitive to stress. Taking time to calm your nervous system can make a big difference.
Helpful practices include:
- Deep breathing
- Meditation
- Journaling
- Spending time in nature
Even small moments of calm during the day can help restore balance.
Move Your Body
Regular movement can help support mood, energy levels, and sleep.
You don’t need intense workouts. Gentle exercise is often enough:
- Walking
- Yoga
- Stretching
- Strength training
Movement also helps regulate stress hormones.
Nourish Your Body
What you eat can influence how you feel during perimenopause.
Focus on:
- Whole foods
- Plenty of vegetables and fibre
- Protein to support energy
- Healthy fats
Staying hydrated and reducing excess caffeine or alcohol may also help with some symptoms.
Be Patient With Yourself
One of the most important things to remember is that perimenopause is a natural life stage, not something that is “wrong” with you.
Your body is adjusting, and it may need more rest, support, and compassion than before.
Listening to your body and practising consistent self-care can make a real difference during this transition.
Final Thoughts
Perimenopause can feel confusing, especially if you weren’t expecting the changes. But understanding what’s happening inside your body can help you feel more in control.
By supporting your physical and emotional wellbeing through self-care, you can navigate this stage of life with greater balance and resilience.
You are not alone in this experience—and learning about your body is one of the most powerful forms of self-care.
