Amenorrhea. The absence of a woman's monthly period not related to menopause.
Androgen. A group of hormones that promote the development and maintenance of male secondary sex characteristics and structures. They are produced in smaller quantities in women and are important in the synthesis of estrogen. They also play a role in sexual function, muscle mass and strength, bone density, distribution of fat tissue, energy, and psychological well-being. With women, the major androgens are produced in the ovaries and adrenal glands and include testosterone, androstenedione, and dehydroepiandrosterone (DHEA).

Also a nonoral prescription drug government approved for the treatment of postmenopausal osteoporosis, although not as potent as other osteoporosis drugs. An example is salmon calcitonin.
Calcium. A mineral that ensures proper functioning of cells in the body including the heart, nerves, muscles, and bones. Calcium is found in the skeleton and teeth, in the cells, and in the blood. Adequate calcium intake is essential for healthy bones with beneficial effects on hypertension, colorectal cancer, obesity, and kidney stones as well. Calcium is best absorbed through dietary sources, including dairy foods, some leafy green vegetables, oily fish, calcium-fortified foods, tofu, and nuts. Nonprescription supplements are also available. An example is calcium carbonate (marketed as Tums, among others).

Estrogen levels fall after menopause. Several types of estrogen therapies are available for menopause indications. Also available in some contraceptives, but at much higher doses than those used for menopause treatment. See also Estrogen therapy (ET).
Estrogen patch. Or Estrogen skin patch or Estrogen transdermal delivery system. A form of estrogen therapy contained in a special patch that is adhered to the skin. The patch technology allows a gradual release of estrogen through the skin directly into the bloodstream where it circulates throughout the entire body (systemically), affecting many different tissues. See also Estrogen.

Common, benign (noncancerous) tumors (myomas) made up of muscle cells and connective tissue that develop within the wall of the uterus. Fibroids are a common cause of abnormal uterine bleeding in midlife and beyond. See also Abnormal uterine bleeding. Follicle-stimulating hormone (FSH). A hormone produced by the pituitary gland (located at the base of the brain). In women, FSH stimulates the growth of ovarian follicles (the small cysts that hold the eggs) and the supporting cells responsible for the growth and nurturing of the egg. FSH also stimulates production of estrogen by the ovaries. When estrogen production is low (after menopause), FSH levels will be high. Formication. Irritating sensations to the skin, ranging from severe itching to phantom symptoms of “ants crawling on their skin” experienced by some perimenopausal women. Fracture.

Gonadotropin-releasing hormone (GnRH). A hormone released by the hypothalamus (a region in the brain) that helps suppress ovarian production of estrogen. Drugs similar to GnRH are sometimes prescribed to shrink fibroid tumors or control abnormal uterine bleeding. Government approved. In the prescription drug approval process in the United States, a manufacturer sends study information on a product to the Food and Drug Administration (FDA), which considers its effectiveness, dosage, side effects, and possible risks. If FDA approval is given, the product may then be offered on the US market for the approved health indication(s). The FDA also monitors product purity and advertising. Health Canada provides this function in Canada. Gynecologist. A doctor who specializes in the care and health of the female reproductive organs.
HDL cholesterol. High-density lipoprotein, referred to as "good" cholesterol. High HDL helps to lower the risk of heart disease.

Hot flash. A condition resulting in a red, flushed face and neck, perspiration, an increased pulse rate, and a rapid heart beat, often followed by a cold chill. Sometimes called a hot flush, this is the most common menopause-related discomfort thought to be the result of changes in the hypothalamus, the part of the brain that regulates the body’s temperature. If the hypothalamus mistakenly senses that a woman is too warm, it starts a chain of events to cool her down. Blood vessels near the surface of the skin begin to dilate (enlarge), increasing blood flow to the surface in an attempt to dissipate body heat. See also Vasomotor symptoms.
HRT or Hormone replacement therapy. Term once used to describe hormone therapy (HT) for menopause, now disallowed by government regulators. See also Hormone therapy (HT).
Hyperplasia. See Endometrial hyperplasia.

Memory & concentration changes There is no firm evidence that memory or other cognitive skills actually decline because of natural menopause. However, difficulty remembering and concentrating are common complaints during perimenopause and the years right after menopause.
Menarche. The first menstrual period.
Menopause. The final menstrual period, which can be confirmed after going 12 consecutive months without a period. This time marks the permanent end of menstruation and fertility. It is a normal, natural event associated with reduced functioning of the ovaries, resulting in lower levels of ovarian hormones (primarily estrogen).
Menopause transition. See Perimenopause.
Menses. The menstrual period.
Menstrual cycle. The time each month (typically every 4 weeks) when an egg develops in the ovary, the lining of the uterus thickens, and the egg is released into the uterus. If the egg is not fertilized by sperm, the lining of the uterus (with the egg tissue) is shed through menstruation and the cycle begins again. This cycle typically becomes irregular during perimenopause and ends completely at menopause. See also Menstruation.
Menstruation. A woman's "period”—the discharge of blood, secretions, and tissue debris from the uterus that recurs in nonpregnant women. See also Menstrual cycle.
Metabolic syndrome.

Night sweats. Hot flashes that occur at night that can interfere with sleep, even if they are not strong enough to cause awakening. If heavy perspiration occurs, the condition is called night sweats. While it is a myth that menopause makes a woman irritable, inadequate sleep causes fatigue, which may lead to irritability. See also Hot flashes.
Obesity. Excessive accumulation of fat in the body defined as a body mass index over 30. Obesity is associated with adverse health consequences including type 2 diabetes, cardiovascular disease, stroke, hypertension, some cancers, osteoarthritis, and premature death. See also Body Mass Index.

Osteoporosis. Postmenopausal osteoporosis is a disease of older women in which the bone density of the skeleton has decreased to a point where bone has become fragile and at higher risk for fractures, often with little or no trauma. In most women, bone loss accelerates during the first few years after menopause, which is related to the decline in estrogen levels.

Pelvic ultrasound. A test that uses sound waves to produce an electronic image of the organs of the pelvis.
Pelvis. The lower part of the abdomen, located between the hip bones.
Perimenopause. A span of time typically lasting 6 years or more that begins with the onset of menstrual cycle changes and other menopause-related symptoms and extends through menopause (the last menstrual period) to 1 year after menopause. Perimenopause is experienced only with spontaneous (natural) menopause, not induced menopause. Also called the menopause transition. See also Induced menopause.

Premenopause. The span of time from puberty (onset of menstrual periods) to perimenopause.
Progesterone. A female hormone that is released by the ovaries after ovulation to prepare the lining of the uterus (endometrium) to receive and sustain the fertilized egg and thus permit pregnancy. If pregnancy does not occur, progesterone (and estrogen) levels fall, resulting in menstruation. Available in prescription and nonprescription therapies (as a bioidentical hormone). See also Hormone therapy.
Progestin. A class of progestogen compounds synthesized to act like progesterone in the body. Available in oral prescription drugs and combined with estrogen in prescription skin patches. See also Progestogen, Hormone therapy.

See also Progesterone, Progestin, Hormone therapy.
Prolapse. The falling down or slipping of a body part from its usual position (eg, with a uterus or bladder if the ligaments holding it in place become stretched). See also Bladder prolapse.
Raloxifene. A type of a class of drugs known as selective estrogen-receptor modulators (SERMs), this oral prescription drug (marketed as Evista) is government approved for the prevention and treatment of osteoporosis in postmenopausal women. Raloxifene is also being studied as a breast cancer prevention drug. See also Selective estrogen-receptor modulator.

Supplements cannot, therefore, achieve a “government-approved” status and do not have to provide package inserts on how to take a drug safely, identify its negative side effects, or avoid potentially dangerous interactions with other drugs. Marketers of supplements are not legally permitted to make health claims for non-disease conditions (eg, hot flashes) without research to prove the claims. See also Government approved.
Surgical menopause. Induced menopause that results from surgical removal of both of the ovaries (bilateral oophorectomy) for medical reasons. Surgical menopause can occur at any age before spontaneous menopause. See also Bilateral oophorectomy, Induced menopause.
Systemic therapy. Drug therapy that circulates through the body, affecting many body systems. Examples include oral and skin patch estrogen drugs. See also Local therapy.
T-score, Z-score. Values that report the results of evaluating bone strength and predicting fracture risk. The Z-score compares the bone density to similar-age women and is a rough index of the need for extra diagnostic studies, whereas the T-score compares bone density to young women and is a rough index of the need for treatment. See also Bone density, DXA scan.
Tamoxifen. A prescription selective estrogen-receptor modulator (SERM; marketed as Nolvadex) that is approved for the prevention and treatment of breast cancer in high-risk women. Although it has an anti-estrogen effect in the breast, it acts like an estrogen in the uterus and may cause the lining to thicken. See also Selective estrogen-receptor modulator.
Temporary menopause. Term used to describe the event of menstrual periods stopping temporarily due to lifestyle factors such as high levels of stress, excessive exercising and/or dieting, or due to medications used to treat fibroids, endometriosis, or PMS. Once a woman adopts a healthier lifestyle or stops her medication, her ovaries may resume normal production of hormones.
Teriperatide. An injectable prescription drug (marketed as Forteo) government approved to treat postmenopausal osteoporosis in women at high risk for fracture. Similar to naturally occurring parathyroid hormone (PTH). See also Parathyroid hormone, Osteoporosis.
Testosterone. The male androgen hormone that is essential for sperm production and responsible for inducing and maintaining male secondary sex characteristics. In women, testosterone (partially produced by the ovaries) may regulate sexual desire and may also help maintain bone and muscle health. See also Androgen.
Thyroid gland. A gland located beneath the voice box in the throat that produces thyroid hormone, which helps regulate growth and metabolism.
Transdermal therapy. Therapy delivered through the skin into the bloodstream, such as via a skin patch or a topical lotion, cream, or gel. See also Estrogen patch.
Tubal ligation. The tying, clamping, and/or cutting of the fallopian tubes to prevent pregnancy and induce sterility. See also Vasectomy.
Urge incontinence. Involuntary leakage of urine accompanied by a sense of urgency (cannot reach the bathroom on time), usually due to overactive bladder. May be helped by medication and/or pelvic floor therapy. See also Kegel exercises.
Urinary incontinence. Involuntary loss of urine caused by any number of conditions, including urinary tract infection, pelvic relaxation, and bladder contractions. See also Incontinence, Stress incontinence, Urge incontinence.
Urinary tract infection (UTI). An often uncomfortable condition that occurs when bacteria in the urinary tract cause infection and inflammation. Typical treatment is an antibiotic.
Urogynecologist. A gynecologist specially trained to treat problems of the female urogenital (urinary and reproductive) system, such as incontinence and pelvic relaxation problems.
Urologist. A doctor specially trained to treat problems of the urinary system.
Uterine bleeding. Any bleeding that originates in the uterus, including a menstrual period, but typically used to describe abnormal uterine bleeding. See also Abnormal uterine bleeding.
Uterus. The small, hollow, pear-shaped organ in a woman's pelvis where menstrual bleeding originates and in which a fetus develops. See also Hysterectomy, Womb.
Vagina. The tube that joins the cervix (the lower part of uterus) to the outside of the body. It is also known as the birth canal.
Vaginal atrophy. A condition in which estrogen loss causes tissues of the vulva (the external parts of the female genital organs) and the lining of the vagina to become thin, dry, and less elastic. Vaginal secretions diminish, resulting in decreased lubrication.
Vaginal dryness. Inadequate lubrication of the vagina that can be caused by low estrogen levels, medication, or lack of sexual arousal.
Vaginal estrogen. Prescription estrogen therapy that is applied vaginally (as cream, ring, suppository, or tablet) and is government approved to treat moderate to severe vaginal dryness and atrophy. Most vaginal estrogen therapies provide local, not systemic, treatment. An example is Vagifem vaginal tablet. See also Local therapy.
Vaginal lubricant. Nonprescription, water-based products that are applied to the vagina to decrease friction and reduce discomfort during intercourse. Common brands include Astroglide, K-Y Personal Lubricant, Lubrin, and Moist Again.
Vaginal moisturizer. Nonprescription products similar to vaginal lubricants, but offering longer duration of effect by replenishing and maintaining water content in the vagina, often preferred by women who have symptoms of irritation, itching, and burning that are not limited to intercourse. Vaginal moisturizers also help to keep a healthy pH (level of acidity) in the vagina, helping to guard against infection (but not sexually transmitted infections). Common brands include K-Y Long-Lasting Moisturizer and Replens.
Vaginitis. Inflamed vaginal tissues that result in vaginal discharge, burning, or irritation. Tissues may be prone to injury, tearing, and bleeding during sexual intercourse or a pelvic examination.
Vasectomy. Outpatient surgical procedure for males to induce sterility.
Vasomotor symptoms. Also known as hot flashes and night sweats, common symptoms during perimenopause and early postmenopause. In almost all women, menopause-related vasomotor symptoms subside over time without any intervention. See also Hot flashes, Night sweats.
Vitamin D. A nutrient that enables the body to absorb calcium, among other things. It is normally produced within the skin in response to sunlight, provided no sunscreen is worn. Also available in supplement form, usually recommended for those at risk of inadequate sun exposure.
Vulva. The external parts of the female genitalia (lips or labia) around the opening of the vagina. Vulvodynia. Pain in the vulva, usually described as a burning, stinging, itching, irritating, or raw feeling.
Weight-bearing exercise. Exercise during which bones and muscles work against the force of gravity or bear the body’s weight. Examples include brisk walking, jogging, dancing, and resistance training exercises. May slow bone loss in the early postmenopausal years and reduce fracture risk.

Womb. Another name for the uterus, the female organ in which a fetus develops.
Women's Health Initiative (WHI). Large research project established by the National Institutes of Health in 1991 to look into the most common causes of death, disability, and impaired quality of life in postmenopausal women. The findings most reported by the media refer to oral hormone therapy (Premarin or Prempro) initiated in older women (past perimenopause) to determine its relationship to cardiovascular disease, stroke, breast cancer, osteoporosis, colon cancer, and other conditions.
Women's health specialist. A doctor, nurse practitioner, physician assistant, or other allied health professional specializing in women's health issues.
