Menopause

Menopause is a normal part of life, just like puberty. That's why some people call menopause "the change of life" or "the change." Menopause is the time in a woman's life when her period stops, but symptoms can begin several years before that. And these symptoms can last for months or years after. Some time around 40, you might notice that your period is different how long it lasts, how much you bleed, or how often it happens may not be the same. Or, without warning, you might find yourself feeling very warm during the day or in the middle of the night. Changing levels of estrogen and progesterone, which are two female hormones made in your ovaries, might lead to these symptoms.

This time of change, called perimenopause by many women and their doctors, often begins several years before your last menstrual period. It lasts for 1 year after your last period, the point in time known as menopause. A full year without a period is needed before you can say you have been through menopause. Postmenopause follows menopause and lasts the rest of your life.

Menopause doesn't usually happen before you are 40, but it can happen any time from your 30s to your mid 50s or later. The average age is 51. Smoking can lead to early menopause. Some types of surgery can bring on menopause. For example, removing your uterus (hysterectomy) before menopause will make your periods stop, but your ovaries will still make hormones. That means you could still have symptoms of menopause like hot flashes when your ovaries start to make less estrogen. But, when both ovaries are also removed (oophorectomy), menopause symptoms can start right away, no matter what your age is, because your body has lost its main supply of estrogen.
