These terms are used interchangeably to describe the time frame and symptomatology leading up to menopause. Premenopause, or perimenopause may start as early as age 40. The average age of menopause is 51. Symptoms of premenopause or perimenopause before the age of 40 should be evaluated by a doctor.

Premenopause as a term should refer to a woman before menopause has occurred, meaning a woman still having menstrual cycles whether they are regular or irregular. Perimenopause should refer to a woman who has begun to have menstrual irregularities due to changes in hormones, eventually leading to menopause. Technically speaking, all perimenopausal women are premenopausal but not all premenopausal women are perimenopausal.
Premenopause is before menopause and perimenopause is around menopause. In general, premenopause is before any menopausal symptoms begin: a normally menstruating female. Perimenopause describes a time in the female’s life that some of the symptoms of menopause present while there still may be menses occurring. During this time women may experience hot flushes, fatigue, irritability and change in libido. At least 50% of women have no symptoms prior to menopause. Most of the women who do have symptoms, those symptoms will disappear during the five years after menses cease.
