Perimenopause

Perimenopause is the time leading up to menopause (when you have not had your period for twelve months). During perimenopause, your body starts making less of certain hormones (estrogen and progesterone), and you begin to lose the ability to become pregnant.

The duration of perimenopause varies. Women normally go through menopause between ages 45 and 55. Many women experience menopause around age 51. However, perimenopause can start as early as age 35. It can last just a few months or a few years. There is no way to tell in advance how long it will last OR how long it will take you to go through it.

Researchers are studying how depression in a woman's life affects the time she starts perimenopause. Some studies have found that women with a history of depression started perimenopause earlier than women without depression. Women who took antidepressants started perimenopause even earlier. If you start perimenopause early, researchers don't know if you reach menopause faster than other women or if you're just in perimenopause longer.
