Perimenopause often begins much earlier than most women expect. While the average age of menopause in the UK is 51, hormonal changes can start in your early to mid-40s — sometimes even in your late 30s. Because many of the symptoms are not the classic hot flushes you might associate with menopause, they are frequently misattributed to stress, ageing, or mental health conditions.
The unexpected symptoms
Beyond the well-known hot flushes and irregular periods, perimenopause can bring a range of symptoms that catch many women off guard:
- Anxiety and panic attacks: Often appearing for the first time, with no obvious external trigger
- Rage and irritability: Disproportionate emotional reactions that feel out of character
- Joint and muscle pain: Aching that appears seemingly overnight
- Heart palpitations: Alarming but usually benign fluctuations in heart rhythm
- Difficulty sleeping: Waking at 3 or 4 am and being unable to fall back asleep
- Weight gain around the middle: Despite no change in diet or exercise
- Reduced libido: A loss of interest in sex that can affect relationships
- Urinary changes: Increased frequency, urgency, or recurrent urinary tract infections
Why is it so often missed?
Several factors contribute to the diagnostic gap. Blood tests for hormone levels are unreliable during perimenopause because hormones fluctuate dramatically from day to day. Many GPs are not trained to recognise the full spectrum of perimenopausal symptoms. And many women themselves do not connect their symptoms to hormonal changes, particularly if they are still having regular periods.
What can help?
The most important first step is recognition. Once perimenopause is identified as the likely cause of your symptoms, treatment options include:
- HRT (body-identical hormones) to stabilise oestrogen and progesterone levels
- Testosterone replacement for energy, libido, and cognitive function
- Lifestyle modifications including exercise, stress reduction, and dietary adjustments
- Targeted treatments for specific symptoms such as vaginal dryness or urinary changes
You do not need to wait until your periods have stopped to seek help. If you are in your 40s and experiencing new or worsening symptoms, perimenopause may well be the explanation — and effective treatment is available.
