The climacteric,

I
Climacteric vs. menopause
Most people use “menopause” to describe the entire transition, but the medical term for the full scope of changes is the climacteric.
The climacteric — the whole transition
The climacteric refers to the entire transitional period in a woman's life when reproductive function declines and eventually ceases. It encompasses changes to the bones, cardiovascular system, brain, skin, metabolism, mood, sleep, urogenital health, and much more. It typically spans from the late 30s through the 60s. Think of it as the full journey — perimenopause, menopause itself, and the postmenopausal years — including every system in the body that responds to shifting hormones.
Menopause — a single point in time
Menopause, technically, refers to a single point in time — the permanent cessation of menstruation. The word itself comes from the Greek mēn (month) and pausis (cessation). It is confirmed retrospectively after 12 consecutive months without a period. While “menopause” has become the common shorthand for the entire transition, it's just one milestone within the much larger climacteric experience.
