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, vasomotor symptoms such as hot flashes and palpitations, psychological symptoms such as increased depression, anxiety, irritability, mood swings and lack of concentration, and atrophic symptoms such as vaginal dryness and urgency of urination appear. Together with these symptoms, the woman may also have increasingly scanty and erratic menstrual periods.
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. Menopause can either be natural or surgically induced. A natural or physiological menopause refers to the ceasing of menses that is a part of a woman's normal ageing process. However, a surgically induced menopause refers to the ceasing of menses for reasons such as because the woman has had a previous hysterectomy.
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.
Menopause is rare in animal species. One possible explanation for its evolution in humans is the grandmother hypothesis.
Common symptoms:
Changes in periods. One of the first signs may be a change in a woman’s periods. Many women become less regular; some have a lighter flow than normal; others have a heavier flow and may bleed a lot for many days. Periods may come less than 3 weeks apart or last more than a week. There may be spotting between periods. Women who have had problems with heavy menstrual periods and cramps will find relief from these symptoms
when menopause starts.
Hot flashes. A hot flash is a sudden feeling of heat in the upper part or all of your body. Your face and neck become flushed. Red blotches may appear on your chest, back, and
arms. Heavy sweating and cold shivering can follow. Flashes can be as mild as a light blush or severe enough to wake you from a sound sleep (called night sweats). Most flashes last between 30 seconds and 5 minutes.
Problems with the vagina and
bladder. The genital area can get drier and thinner as estrogen levels change. This dryness may make sexual intercourse painful. Vaginal infections can become more common. Some women have more urinary tract infections. Other problems can make it hard to hold urine long enough to get to the bathroom. Some women find that urine leaks during exercise, sneezing, coughing, laughing, or running.
Sex. Some women find that their feelings about sex change with menopause. Some have changes to the vagina, such as dryness, that makes sexual intercourse painful. Others feel freer and sexier after menopause — relieved that pregnancy is no longer a worry. Until you have had 1 full year without a period, you should still use birth control if you do not want to become pregnant. After menopause a woman can still get sexually transmitted diseases (STDs), such as HIV/AIDS or gonorrhea. If you are worried about STDs, make sure your partner uses a condom each time you have sex.
Sleep problems. Some women find they have a hard time getting a good night’s sleep – they may not fall asleep easily or may wake too early. They may need to go to the bathroom in the middle of the night and then find they aren’t able to fall back to sleep. Hot flashes also may cause some women to wake up.
Mood changes. There may be a relationship between changes in estrogen levels and a woman’s mood. Shifts in mood may also be caused by stress, family changes such as children leaving home, or feeling tired. Depression is NOT a symptom of menopause.
Changes in the body. Some women find that their bodies change around the time of menopause. With age, waists thicken, muscle mass is lost, fat tissue may increase, skin may get thinner. Other women have memory problems, or joint and muscle stiffness
and pain. With regular exercise and attention to diet, many of these changes may be eased or prevented.
Treatment of symptoms
Medical treatments for menopausal symptoms have been developed. Most notably, Hormone Replacement Therapy (HRT), has been used to reduce the weakening of bones (known as osteoporosis) 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 disease, breast cancer, heart disease and stroke.
