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.
Postmenopause is the stage after a person has not had a
menstrual cycle for 12 months. They will 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.
