What is pre, peri, and post menopause?
Pre-menopause refers to the one or two years immediately before menopause or to the whole reproductive period prior to the menopause. The World Health Organization recommends that the latter definition, encompassing the entire reproductive period up to the final menstrual period, be used.
Peri-menopause or "around menopause" refers to the period immediately before menopause (when endocrinological, biological, and clinical features of approaching menopause begin) as well as the first year after menopause.
Post-menopause refers to the period after the final menstrual period.[i]
