Your sleep changes, your cycle changes or you feel less resilient than before: this may fit perimenopause. One symptom alone does not answer the question. Looking at age, the course of changes and how they interact is more helpful.

What does perimenopause mean?

Perimenopause describes the transition around the last natural menstrual period. Ovarian function changes during this time. Ovulation becomes less reliable and hormone production more uneven. Periods may continue while symptoms are already present.

The terms are often mixed in everyday use: menopause is the last natural menstrual period. It can only be identified retrospectively, after twelve months without another natural period and with no other cause. Postmenopause is the time afterwards. The scientific STRAW classification also includes the first year after the last period within perimenopause.

At what age does the transition begin?

It often starts in the mid-to-late forties. Changes can occur earlier. However, fatigue or sleep problems at 35 do not automatically mean perimenopause. Particularly under 40, new cycle changes deserve targeted investigation rather than premature classification as normal menopause.

Which symptoms can occur?

  • New changes in cycle length or bleeding intensity.
  • Hot flushes and night sweats.
  • Sleep problems, concentration difficulties or brain fog.
  • Altered mood, irritability or anxiety.
  • Vaginal dryness, pain during sex or urinary symptoms.

Not every woman experiences all symptoms. This list is not a diagnostic checklist: several symptoms may have other causes or reinforce one another.

What does the cycle tell us?

Repeated substantial differences between consecutive cycles can indicate an early transition. Longer new gaps in bleeding may occur later. One late period is less informative. These patterns cannot simply be used with hormonal contraception, PCOS, breastfeeding or after certain operations.

How long does perimenopause last?

It extends over several years; duration and symptoms vary considerably. The often-mentioned guide of about four years is not a countdown for an individual woman. Symptoms may also continue after the last period.

When should you seek medical advice?

If symptoms affect daily life, you do not need to wait until periods stop completely. Heavy or prolonged bleeding, bleeding between periods and bleeding after sex should be assessed by a gynaecologist. Any new bleeding after twelve months without a natural period also requires assessment.

Preparing for the consultation

For a few weeks, record bleeding days, sleep, hot flushes and the symptoms that trouble you most. Bring a medicine list and previous findings. Our perimenopause check helps organise these observations. It does not replace a diagnosis.
