What is Menopause?
Menopause is defined as the point in time when menstrual cycles permanently cease due to the natural depletion of ovarian oocytes from aging. The diagnosis is typically made retrospectively after the woman has missed menses for 12 consecutive months. It marks the permanent end of fertility and the average age of menopause is 51 years.
The menopausal transition most often begins between ages 45 and 55. It usually lasts about 7 years but can last as long as 14 years. During the menopausal transition, the body’s production of estrogen and progesterone, two hormones made by the ovaries, varies greatly. Bones become less dense, making women more vulnerable to fractures. During this period, too, the body begins to use energy differently, fat cells change, and women may gain weight more easily.
