Menopause

Menopause (also known as the "Change of life" or climacteric) is a stage of the human female reproductive cycle that occurs as the ovaries stop producing estrogen, causing the reproductive system to gradually shut down. As the body adapts to the changing levels of natural hormones, symptoms such as hot flushes, mood swings, vaginal dryness, increased depression and anxiety, and increasingly scanty and erratic menstrual periods are common.

Technically, menopause refers to the ceasing of menses, whereas the gradual process through which this occurs, which typically takes a year but may last as little as six months or more than five years, is known as climacteric. Popular use however replaces climacteric with menopause.

The average onset of menopause is 50.5 years, but some women enter menopause at a younger age, especially if they have suffered from cancer or another serious illness and undergone chemotherapy. Premature menopause (or Premature Ovarian Failure) is defined as menopause occurring before the age of 40, and occurs in 1% of women. Other causes of premature menopause include autoimmune disorders like thyroid disease or diabetes mellitus. Premature menopause is diagnosed by measuring the levels of follicle stimulating hormone (FSH) and luteinizing hormone (LH); the levels of these hormones will be higher if menopause has occurred.

Post-menopausal women, especially Europeans, are at increased risk of osteoporosis.

Medical treatments for menopausal symptoms have been developed. Most notably, Hormone Replacement Therapy (HRT), has been used to reduce the weakening of bones and the risk of heart disease after menopause. However, some women have resisted the implication that menopause is a disorder, seeing it as a natural stage of life. There has also been scientific controversy over whether the benefits of HRT outweigh the risks. Specifically, recent studies have suggested that HRT may increase women's risk for Alzheimer's, breast cancer, heart disease and stroke.
