Perimenopause: the years before menopause that nobody warns you about
Not feeling like yourself lately? You're not imagining it, and you're almost certainly not "too young." Perimenopause is the transition leading up to menopause, and it can begin years — sometimes a decade — before your periods actually stop. For many women it starts in their early-to-mid 40s, and for some, in their late 30s.
What's actually happening
Perimenopause isn't a steady, gentle decline in your hormones. It's the opposite: your oestrogen and progesterone swing up and down erratically from one month to the next. That hormonal turbulence is why the symptoms can feel so unpredictable, and why one month can feel fine and the next anything but.
The signs to look for
Periods that change — closer together, further apart, lighter, heavier
Sleep that breaks, often waking in the early hours
Mood shifts, irritability or new anxiety
Brain fog and word-finding lapses
Hot flushes or night sweats
Changes in energy, libido or weight
Because these creep in gradually and overlap with ordinary busy-life stress, perimenopause is one of the most under-recognised stages in a woman's health.
Why your bloods can come back "normal"
This is the part that frustrates so many women. Because hormone levels fluctuate so wildly during perimenopause, a single blood test can land on a "normal" day even when you're well into the transition. That's why perimenopause is largely diagnosed on your age and your symptoms — your story matters as much as any number on a lab report.
What helps
There's a lot you can do, from lifestyle foundations (sleep, strength, stress, nutrition) to medical options worth discussing with a doctor. The right approach depends on your symptoms, your health history and your preferences — which is exactly the conversation to have with a clinician who takes perimenopause seriously.
