Menopause
The menopause transition typically begins between 40 and 50 years of age (average 47.5). The duration of perimenopause may be for up to eight years. Women will often, but not always, start these transitions (perimenopause and menopause) about the same time as their mother did.
Menopause
The date of the final menstrual period is usually taken as the point when menopause has occurred. During the menopausal transition and after menopause, women can experience a wide range of symptoms.
