You are not sleeping well. Your periods have become unpredictable. You snap at your partner, then find yourself crying twenty minutes later. Then you wonder if it's stress, ageing—or hormonal.
If that sounds familiar, you're not alone. Many women go months—or even years—feeling unlike themselves before anyone mentions perimenopause [1,2]
What is perimenopause, exactly?
Perimenopause is the transitional phase before menopause, marked by fluctuating estrogen and progesterone levels leading to various symptoms. It generally lasts 4–8 years, sometimes shorter or stretching to a decade [3,2,4].
Menopause, by definition, is the single day when you’ve gone 12 months without a period; everything before belongs to perimenopause [1,5].
First and most common signs of perimenopause:
- Changes to menstrual cycles (shorter, longer, lighter, heavier, or no change at all), while other symptoms like hot flushes or sleep issues begin—these can still indicate perimenopause [5,6].
- Sleep disruption, mood swings, hot flushes/night sweats, brain fog, tender breasts, bloating, joint discomfort, dry skin, vaginal dryness, decreased libido.
- These symptoms are often dismissed as stress or simply 'getting older' [6,2].
When does perimenopause usually start?
Most women enter perimenopause in their mid to late 40s (around age 47), but some can begin in their late 30s [5,6].
Risk factors for earlier onset include smoking, chemotherapy, being underweight, or a family history of early menopause [7,8].
Is there a test for perimenopause?
No definitive test exists. Hormonal levels like FSH or estrogen fluctuate too much to be reliable. Diagnosis is clinical—based on age, menstrual changes, and symptoms [1,2].
FSH measurements may be used in select cases—such as women aged 40–45 with symptoms, or under age 40 to rule out premature ovarian insufficiency [2].
What can help?
There’s no one-size-fits-all solution—but plenty of options can help you feel better:
- Lifestyle adjustments: Prioritize sleep hygiene, minimize caffeine and alcohol, and practice stress-reduction techniques like mindfulness or gentle exercise [6].
- Nutritional support: Calcium and vitamin D supplements support bone health as estrogen decreases [3].
- Non-hormonal support: Cognitive behavioural therapy (CBT) can ease mood and sleep disruption. Vaginal moisturisers or lubricants help with dryness and discomfort [3,9].
- Hormone Replacement Therapy (HRT) remains the most effective treatment for relieving symptoms and protecting long-term health, when no contraindications are present [10,3].
You are not imagining it
Many women feel confused, dismissed, or even gaslit about what they are going through. If you are reading this and thinking, "This is me," that is a sign in itself.
Perimenopause is real. You deserve care that listens, informs, and takes action. If you are not sure what you are going through, you are not alone. Our clinicians specialise in this stage of life, and we are here to help you make sense of it.
