Menopause is the point in a woman's life when menstruation stops for good. This means she is no longer able to have children. Menopause occurs in most women between the ages of 35 and 58. It is a natural event in a woman's life. Surgical menopause occurs when a woman has both of her ovaries removed.
By the time a woman is in her mid 30s, the level of the hormone estrogen in her body begins to drop. Levels gradually decline until a woman stops menstruating. The period during which estrogen levels are dropping but the woman is still menstruating is called perimenopause or premenopause. The point at which the estrogen level has declined enough so that menstruation stops is called menopause. The period of time that begins after menstruation permanently stops is known as postmenopause.
Menopause is a natural part of a woman's life. A woman's estrogen level decreases over time, causing her to stop menstruating. A woman who has her ovaries removed because of disease will also go through menopause.
