When does menopause occur?

It can begin before you turn 40, but many women continue to menstruate well into their 50s or 60s. The average age for U.S. women having their last period is 51. Your mother’s age at menopause is highly predictive of yours.

Menopause is a natural process, not an event. It proceeds slowly, often lasting 8 - 10 years. It begins when your body slows down its production of estrogen and progesterone, the hormones that set the stage for pregnancy.

Ovulation and menstruation become irregular. Some months you may ovulate and have a period; other months you may not. You may also experience other symptoms, such as vaginal dryness, weight gain, and mood swings -- problems that you may initially attribute to your diabetes.

Menopause occurs most commonly in Westernized countries at an average age of 51, with a typical range of 45 to 55 years of age. In some countries, such as in India and the Philippines, the average age of menopause is much lower, about 44 years old. The reason for this is unclear. Women who have had a hysterectomy and are thus unable to have menstrual periods can be diagnosed as reaching menopause with a blood test that measures the level of follicle-stimulating hormone or FSH, which increases during the menopause.

Menopause is defined as occurring one year after a woman's last period. The average age of menopause is 51, but the physiologic processes surrounding the ovaries' retirement usually begin when a woman is in her midforties.
Menopause is the definite end of menstruation and fertility, usually occurring during your 40s or 50s (average age is 51). The main cause of menopause is the natural decline of reproductive hormones (estrogen and progesterone) until eventually, fertility diminishes and ovaries stop producing eggs, therefore terminating periods. The physical and emotional symptoms of menopause include irregular periods, low energy, vaginal dryness, hot flashes, night sweats, sleep problems, sadness, mood changes, weight gain, anxiety, dry skin, and thin hair.

In specific medical terms, menopause in the last menstrual period. When a health care provider asks a woman when she had menopause, the date of the last menstrual period is what is being asked. In the United States the median age of menopause is 51 years. Half of women will have their last period before this age and the remaining half will have the last period after this age.
However in everday life we often refer to the whole menopausal transition as "menopause."

Menopause is the time in a woman's life when her periods (menstruation) eventually stop and the body goes through changes that no longer allow for pregnant. It is a natural event that normally occurs in women age 45 - 55. And for some women can be incredibly upsetting and emotionally traumatic. Not to mention the sometimes extreme side effects of menopause that can last years.
