The average age of menopause is 51 years, but the exact calculation method for predicting its occurrence does not exist, even the age of the first menstruation can not correlated with age of menopause. Most women reach her in age from 45 to 55 years, but it may come in the past 30, 40 years or even stepped up to 60. As a rule, however, menopause in women occurs in the same age as her mother.
Perimenopause is often accompanied by disturbances in the menstrual cycle, as well as the typical symptoms of early menopause, which may begin 10 years before the last menstrual period.
Some medical and surgical conditions can affect the timing of menopause.
Surgical removal of the ovaries
Sometimes this procedure is called surgical or induced menopause. In this case, usually there is no peri-menopause and after surgery, the woman experiences the symptoms of menopause. Many women who have undergone this operation, note that the suddenness of the symptoms of menopause especially hard impact on health, although the effects may not be so painful.
Often the ovaries are removed along with the uterus, this is called a hysterectomy. If removal of the uterus occurs without removal of both ovaries, they continue to function and produce normal amounts of hormones. And although women can no longer be menstruation, the ovaries will produce hormones until the age of natural menopause. Although women may manifest other symptoms of menopause - hot flashes, mood swings. However, it may happen fading functioning of the ovaries, and in a year or two after hysterectomy comes menopause.
Chemotherapy and radiation therapy
Depending on the type of cancer and the method of its treatment, chemotherapy and radiation therapy can lead to menopause, if you have held during ovulation. In this case, the symptom of menopause can begin as during cancer treatment and several months after the procedure.
Premature cessation of functioning of the ovaries
Premature extinction is the cessation of the functioning of the ovaries before age 40 years. About 1 percent of women around the world are subject to him, the causes of this phenomenon remain to be elucidated, but the doctors think that this is due to genetic factors or autoimmune diseases.
Because every woman's hormone levels fluctuate from day to day, measuring their level is not a reliable method for diagnosing menopause. If today is low, they can grow from the same woman the next day. There is no blood test, which would be absolutely identified menopause. To help in its identification can only tests to exclude other causes for unstable cycle, if no other reasons, then menopause. The only way to correctly diagnose the menopause is the absence of menstruation for 12 months.
