What Is Perimenopause?

If you've heard the word "perimenopause" but aren't quite sure what it means, or when it's supposed to start, you're far from alone. It's one of the most common — and most misunderstood — stages of a woman's life.

The Simple Definition

Perimenopause is the transitional phase leading up to menopause. It's when your body starts producing less oestrogen, causing hormone levels to fluctuate rather than drop in one smooth line. Periods usually become irregular during this time — but they haven't stopped altogether, which is the key difference between perimenopause and menopause itself.

Menopause is officially reached once you've gone 12 consecutive months without a period. Everything before that point — sometimes for years — is perimenopause.

When Does It Start?

Perimenopause typically begins in a woman's mid-to-late 40s, though it can start earlier for some. It can typically last around four years, but it isn't unusual for it to run anywhere from a few years up to eight or more. Combined with the years of symptoms that can continue after periods stop, some women find the whole transition spans closer to a decade.

What Does It Feel Like?

Because hormone levels are fluctuating rather than steadily declining, perimenopause symptoms can feel unpredictable — some weeks you may feel completely normal, others less so. Common symptoms include:

  • Irregular or changing periods
  • Hot flushes and night sweats
  • Mood changes, anxiety or low mood
  • Sleep disturbance
  • Brain fog or trouble concentrating
  • Vaginal dryness and changes in libido
  • Fatigue and joint aches

Not every woman experiences all of these, and severity varies hugely from person to person. Research increasingly shows perimenopause isn't just a milder version of menopause — it has its own distinct pattern of symptoms, which is part of why it can be so easy to miss or misattribute to something else, like stress.

Do You Need A Test To Know?

Not necessarily. For most women over 45, a diagnosis is usually made based on symptoms alone, without needing a blood test. If symptoms start before 45, a doctor may want to check hormone levels to rule out other causes.

What Can Help

There's no need to simply push through perimenopause. Options include HRT, lifestyle adjustments, and non-hormonal support for specific symptoms like dryness or discomfort. What works best is personal, and often a combination of approaches.

If your symptoms are getting in the way of daily life, it's worth speaking to a GP or menopause specialist — perimenopause is common, well understood, and very manageable once it's recognised for what it is.
