Perimenopause describes the transitional stage before menopause. It’s the time when your menstrual cycles gradually become more irregular before stopping altogether, spelling the end of your reproductive years.

Every woman experiences perimenopause differently and at varying ages. Perimenopause typically takes place between the ages of 45 and 56 years, lasting up to seven years.
2,4 However, the
transition to menopause can take up to 14 years for some people and even start in your 30s.
During perimenopause, you may notice several symptoms that affect your physical and mental health. These symptoms arise from the subtle (and not-so-subtle) changes that take place in your body, such as hormonal changes.
Together, the hormones oestrogen and progesterone are responsible for ovulation and menstruation.5,6 In preparation for menopause, your oestrogen levels begin to decrease, causing a hormonal imbalance. These fluctuations then lead to several changes: your menstrual cycles shorten or lengthen, your ovaries produce fewer eggs, and menopausal-related symptoms, such as hot flushes, vaginal dryness and difficulty sleeping, begin.4
When your periods stop for 12 consecutive months, this signals the end of perimenopause, meaning that you’ve officially reached menopause.4
