Most women first begin developing menopause symptoms about four years before their last period. Symptoms often continue until about four years after a woman’s last period.
A small number of women experience menopause symptoms for up to a decade before menopause actually occurs, and 1 in 10 women experience menopausal symptoms for 12 years following their last period.
The median age for menopause is 51, though it may occur on average up to two years earlier for Black and Latina women. More studies are needed to understand the onset of menopause for women of color.
There are many factors that help determine when you’ll begin menopause, including genetics and ovary health. Perimenopause occurs before menopause. Perimenopause is a time when your hormones begin to change in preparation for menopause.
It can last anywhere from a few months to several years. Many women begin perimenopause some point after their mid-40s. Other women skip perimenopause and enter menopause suddenly.
About 1 percent of women begin menopause before the age of 40, which is called premature menopause or primary ovarian insufficiency. About 5 percent of women undergo menopause between the ages of 40 and 45. This is referred to as early menopause.
