When women in their late thirties or early forties begin to have symptoms of perimenopause such as hot flashes or vaginal dryness, they often wonder whether this is an early menopause. While the average age of menopause in the United States is 51, the usual range is from 45 to 55. If you completely stop having periods before the age of 45, it is called an early menopause. If you stop menstruating even earlier -- before the age of 40 -- it is called premature menopause. There are several reasons you might experience early menopause, including: Surgery to remove your ovaries.
Some people call the years leading up to a woman's last period menopause, but that time actually is the menopausal transition, or perimenopause (PER-ee-MEN-oh-pawz). During the time of the menopausal transition (perimenopause), your periods can stop for a while and then start again. Therefore, the only way to know if you have gone through menopause is if you have not had your period for one year. (And it's not menopause if your periods stop for some other reason, like being sick.) The average age of menopause is 51, but for some women it happens as early as 40 or as late as 55.
