What is menopause?
Menopause is defined as 12 months without a period.
The average age at which women experience menopause
in the United States is 52, with most experiencing
it between ages 45 and 55.
Perimenopause is the time leading up to menopause, when
the ovaries begin producing fewer hormones, and many
people develop symptoms.
Postmenopause is the stage after a person has not
had a menstrual cycle for 12 months. Women remain in postmenopause for the remainder of their
lives.
As women live longer, they spend roughly 40% of
their lives in the postmenopausal years, which
equates to more than 30 years for most women.
