Most women hear about menopause long before anyone mentions perimenopause — the transitional phase that can begin eight to ten years earlier, often in your late 30s or early 40s. It is one of the most common and least understood stages of a woman’s life.
What is actually happening
Perimenopause is driven by fluctuating, not simply declining, levels of oestrogen and progesterone. Your ovaries don’t switch off gradually and predictably — they sputter, surge, and dip, sometimes within the same week. That unpredictability is exactly why symptoms can feel so erratic.
Why it is so often missed
Because periods are usually still happening — just irregular — many women (and even some clinicians) attribute symptoms to stress, ageing, or “just life.” The average woman waits years before getting an accurate explanation for what she is experiencing.
- Cycles that shorten, lengthen, or skip without a clear pattern
- Mood swings that arrive without an obvious trigger
- New sensitivity to heat, alcohol, or sleep disruption
- Brain fog that feels different from ordinary forgetfulness
What helps right now
Tracking your cycle and symptoms — even loosely — gives you and your doctor real data instead of vague impressions. It also helps you recognise that what you are feeling has a name, a timeline, and proven management options, from lifestyle adjustments to hormone therapy when appropriate.
You are not imagining it, and you are not alone — perimenopause affects nearly every woman, yet remains one of the most under-discussed transitions in healthcare.
The first step is simply naming what is happening. From there, you can build a plan that actually fits your body.
