Menopause is defined as a state of absence of menstrual periods for a consecutive period of 12 months. Menopause is a transition period in a woman’s life and it marks the permanent end of fertility. After the menopausal phase, the ovaries cease to function. It is not a medical condition but only a natural process. Menopause might sometimes require medical attention if you exhibit certain severe symptoms. Most women reach menopause between 45 to 55 years of age.
