Easing the Symptoms of Menopause : Menopause is the cessation of a woman’s menstrual period. Menopause usually happens gradually. If you have begun going through menopause, you may notice that you miss some menstrual periods. Thus you may begin to bleed once in two months instead of menstruating every twenty-eight days. In the US, the average age for a female to reach the menopause is fifty-one. Once you have not had a menstrual period for one full year, you are post-menopausal.
