Perimenopause

Also called Menopause transition

Perimenopause is the transition before menopause, when periods change and symptoms such as hot flushes can start.

NICE guideline NG23 describes menopause as a life transition that usually happens in mid-life. In a healthy person aged 45 or over, perimenopause is identified from recently started vasomotor symptoms (hot flushes and sweats) together with changes in the menstrual cycle. Menopause is identified after 12 months without a period when no hormonal contraception is used. No blood test is needed at that age.
