What Is Perimenopause?

Perimenopause is the transition before menopause, when hormone levels change and periods become irregular. It often starts in a woman's 40s and ends once she has gone 12 months without a period.

What are the symptoms of perimenopause?

Hormone changes in perimenopause can cause:

  • irregular periods
  • hot flushes and night sweats
  • sleep problems
  • low mood or anxiety
  • problems with memory and concentration

Symptoms vary a lot. Some women have few, and others find them hard to live with.

How long does perimenopause last?

The perimenopause stage can last several years. Menopause itself is confirmed when a woman has not had a period for 12 months and is not using hormonal contraception. Most reach menopause between 45 and 55.

How is perimenopause diagnosed and treated?

There is no routine test for perimenopause. A GP will usually diagnose it from age and symptoms. Treatment options include lifestyle changes, talking therapies and HRT, and a doctor can explain the benefits and risks of each.

How does perimenopause affect work?

Poor sleep, hot flushes and brain fog can make work harder. Temperature control, a desk fan, access to cold water, flexible hours and time off for GP appointments are practical forms of support.
