Polycystic Ovarian Syndrome (PCOS) Glossary of Terms

The following are health and medical definitions of terms that appear in the Polycystic Ovarian Syndrome (PCOS) article.

Abnormal: Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer).

Acanthosis nigricans: A skin condition characterized by dark thickened velvety patches, especially in the folds of skin in the axilla (armpit), groin and back of the neck. The condition is complex. It can occur with endocrine diseases such as Cushing disease, tumors of the pituitary, and diabetes mellitus. It is common in people who have insulin resistance -- whose body is not responding correctly to the insulin that they make in their pancreas. Acanthosis nigricans also occurs with underlying malignancies (especially carcinomas of the vicera), administration of certain drugs, and as a genetic disorder inherited in an autosomal dominant manner.

Acne: Localized skin inflammation as a result of overactivity of the oil glands at the base of hair follicles. Acne happens when oil (sebaceous) glands come to life around puberty, when these glands are stimulated by male hormones that are produced in the adrenal glands of both boys and girls.
See the entire definition of Acne

Adrenal gland: One of a pair of small glands, each of which sits on top of one of the kidneys. The adrenal is made up of an outer wall (the cortex) and an inner portion (the medulla).
See the entire definition of Adrenal gland

Amenorrhea: Absence or cessation of menstruation. Amenorrhea is conventionally divided into primary and secondary amenorrhea.
See the entire definition of Amenorrhea

Androgen: A male sex hormone that promotes the development and maintenance of the male sex characteristics. The major androgen is testosterone.

Androgenic: Pertaining to the development of male characteristics, including body hair, the genital organs and muscle mass. "Androgenic" is the adjective form of the noun "androgen," a word referring to any of the male hormones, including testosterone and androsterone.
See the entire definition of Androgenic

Anovulatory: Not accompanied by ovulation, the release of an ovum (egg) from the ovary. For example, anovulatory menstruation. Synonymous with anovular.

Arms: An appendage in anatomy and in clinical trials. See: Arm.

Biochemical: Relating to biochemistry, the application of the tools and concepts of chemistry to living systems.
See the entire definition of Biochemical

Birth control: Birth control is the use of any practices, methods, or devices to prevent pregnancy from occurring in a sexually active woman. Also referred to as family planning, pregnancy prevention, fertility control, or contraception; birth control methods are designed either to prevent fertilization of an egg or implantation of a fertilized egg in the uterus.
See the entire definition of Birth control

Blood pressure: The blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. It's measurement is recorded by two numbers. The first (systolic pressure) is measured after the heart contracts and is highest. The second (diastolic pressure) is measured before the heart contracts and lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called "hypertension".

Blood sugar: Blood glucose. See also: High blood sugar; Low blood sugar.

Brain: That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called "hemispheres."

C-reactive protein: A plasma protein that rises in the blood with the inflammation from certain conditions.
See the entire definition of C-reactive protein back to top

Cancer: An abnormal growth of cells which tend to proliferate in an uncontrolled way and, in some cases, to metastasize (spread).
See the entire definition of Cancer

Cardiovascular: The circulatory system comprising the heart and blood vessels which carries nutrients and oxygen to the tissues of the body and removes carbon dioxide and other wastes from them.
See the entire definition of Cardiovascular

Cardiovascular disease: Disease affecting the heart or blood vessels.
See the entire definition of Cardiovascular disease

Cholesterol: The most common type of steroid in the body, cholesterol has gotten something of a bad name. However, cholesterol is a critically important molecule.
See the entire definition of Cholesterol

Chronic: This important term in medicine comes from the Greek chronos, time and means lasting a long time.
See the entire definition of Chronic

Computed tomography: An x-ray procedure that uses the help of a computer to produce a detailed picture of a cross section of the body. Also called a CT scan or CAT scan.

CRP: C-reactive protein.

Cysts: Cysts are abnormal, closed sac-like structures within a tissue that contain a liquid, gaseous, or semisolid substance. Cysts can occur anywhere in the body and can vary in size. The outer, or capsular, portion of a cyst is termed the cyst wall.

Dandruff: A mild skin condition that produces white flakes that may be shed and fall from the hair.
See the entire definition of Dandruff

DHEA: Dehydroepiandrosterone.

Diabetes: Refers to diabetes mellitus or, less often, to diabetes insipidus. Diabetes mellitus and diabetes insipidus share the name "diabetes" because they are both conditions characterized by excessive urination (polyuria).
See the entire definition of Diabetes

Diabetes mellitus: Better known just as "diabetes" -- a chronic disease associated with abnormally high levels of the sugar glucose in the blood. Diabetes is due to one of two mechanisms:
(1) Inadequate production of insulin (which is made by the pancreas and lowers blood glucose) or
(2) Inadequate sensitivity of cells to the action of insulin.
The two main types of diabetes correspond to these two mechanisms and are called insulin dependent (type 1) and non-insulin dependent (type 2) diabetes. In type 1 diabetes there is no insulin or not enough of it. In type 2 diabetes, there is generally enough insulin but the cells upon it should act are not normally sensitive to its action.
See the entire definition of Diabetes mellitus

Diagnosis: 1 The nature of a disease; the identification of an illness. 2 A conclusion or decision reached by diagnosis. The diagnosis is rabies. 3 The identification of any problem. The diagnosis was a plugged IV.
See the entire definition of Diagnosis

Diuretic: Anything that promotes the formation of urine by the kidney. (The word "diuretic" comes from a combination of the Greek "dia-", thoroughly + "ourein", to urinate = to urinate thoroughly).
See the entire definition of Diuretic

Electrolysis: Permanent removal of body hair, including the hair root, with an electronic device. While it is billed as a permanent process, many people find that hair does grow back (albeit slowly) after electrolysis. Electrolysis may be done by a dermatologist, by an electrolysis technician, or in some cases by a facial technologist or esthetician.

Endometrial cancer: Cancer of the womb (the uterus ). Endometrial cancer occurs most often in women between the ages of 55 and 70 years. It accounts for about 6% of cancer in women. Women at elevated risk for endometrial cancer include those who are obese, who have few or no children, who began menstruating at a young age, who had a late menopause, and women of high socioeconomic status. It is thought that most of these risk factors are related to hormones, especially excess estrogen.


See the entire definition of Endometrial cancer

Endometrial hyperplasia: A condition characterized by overgrowth of the lining of the uterus. Hyperplasia means overgrowth. The endometrium is the inner layer of the uterus.

Endometrium: The uterine lining; the cells that line the uterus (the womb); the inner layer of the uterus. This tissue is shed monthly in response to the hormonal changes of the menstrual period. The endometrium then grows back and slowly gets thicker and thicker until the next period when it is once again sloughed off.

Estrogen: Estrogen is a female hormone produced by the ovaries. Estrogen deficiency can lead to osteoporosis.
See the entire definition of Estrogen

Family history: The family structure and relationships within the family, including information about diseases in family members.
See the entire definition of Family history

Fetus: The unborn offspring from the end of the 8th week after conception (when the major structures have formed) until birth. Up until the eighth week, the developing offspring is called an embryo.

Gene: The basic biological unit of heredity. A segment of deoxyribonucleic acid (DNA) needed to contribute to a function.
See the entire definition of Gene

Genetic: Having to do with genes and genetic information.

Genetics: The scientific study of heredity. Genetics pertains to humans and all other organisms. So, for example, there is human genetics, mouse genetics, fruitfly genetics, etc.
See the entire definition of Genetics

Gestational diabetes: See: Diabetes, gestational.

Gland: 1. A group of cells that secrete a substance for use in the body. For example, the thyroid gland. 2. A group of cells that removes materials from the circulation. For example, a lymph gland.

Gonadotropin: Hormones that are secreted by the pituitary gland, and that affect the function of the male or female gonads.
See the entire definition of Gonadotropin

Groin: In anatomy, the area where the upper thigh meets the trunk. More precisely, the fold or depression marking the juncture of the lower abdomen and the inner part of the thigh.
See the entire definition of Groin

Hair loss: Hair loss is the thinning of hair on the scalp. The medical term for hair loss is alopecia. Alopecia can be temporary or permanent. The most common form of hair loss occurs gradually and is referred to as "androgenetic alopecia," meaning that a combination of hormones (androgens are male hormones) and heredity (genetics) is needed to develop the condition. Other types of hair loss include alopecia areata (patches of baldness that usually grow back), telogen effluvium (rapid shedding after childbirth, fever, or sudden weight loss); and traction alopecia (thinning from tight braids or ponytails).
See the entire definition of Hair loss

HDL: High density lipoprotein.
See the entire definition of HDL back to top

Heart: The muscle that pumps blood received from veins into arteries throughout the body. It is positioned in the chest behind the sternum (breastbone; in front of the trachea, esophagus, and aorta; and above the diaphragm muscle that separates the chest and abdominal cavities. The normal heart is about the size of a closed fist, and weighs about 10.5 ounces. It is cone-shaped, with the point of the cone pointing down to the left. Two-thirds of the heart lies in the left side of the chest with the balance in the right chest.
See the entire definition of Heart

Heart disease: Any disorder that affects the heart. Sometimes the term "heart disease" is used narrowly and incorrectly as a synonym for coronary artery disease. Heart disease is synonymous with cardiac disease but not with cardiovascular disease which is any disease of the heart or blood vessels. Among the many types of heart disease, see, for example: Angina; Arrhythmia; Congenital heart disease; Coronary artery disease (CAD); Dilated cardiomyopathy; Heart attack (myocardial infarction); Heart failure; Hypertrophic cardiomyopathy; Mitral regurgitation; Mitral valve prolapse; and Pulmonary stenosis.

High blood pressure: Also known as hypertension, high blood pressure is, by definition, a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90.
See the entire definition of High blood pressure

Hirsutism: Having an overabundance of hair. A person with hirsutism is said to be hirsute (pronounced hir-suit).
See the entire definition of Hirsutism

Hormone: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs.
See the entire definition of Hormone

Hyperplasia: A condition in which there is an increase in the number of normal cells in a tissue or organ.

Hypothyroid: Deficiency of thyroid hormone which is normally made by the thyroid gland which is located in the front of the neck:

Infertility: The diminished ability or the inability to conceive and have offspring. Infertility is also defined in specific terms as the failure to conceive after a year of regular intercourse without contraception.
See the entire definition of Infertility

Inflammation: A basic way in which the body reacts to infection, irritation or other injury, the key feature being redness, warmth, swelling and pain. Inflammation is now recognized as a type of nonspecific immune response.
See the entire definition of Inflammation

Insulin: A natural hormone made by the pancreas that controls the level of the sugar glucose in the blood. Insulin permits cells to use glucose for energy. Cells cannot utilize glucose without insulin.
See the entire definition of Insulin

Insulin resistance: The diminished ability of cells to respond to the action of insulin in transporting glucose (sugar) from the bloodstream into muscle and other tissues. Insulin resistance typically develops with obesity and heralds the onset of type 2 diabetes. It is as if insulin is "knocking" on the door of muscle. The muscle hears the knock, opens up, and lets glucose in. But with insulin resistance, the muscle cannot hear the knocking of the insulin (the muscle is "resistant"). The pancreas makes more insulin, which increases insulin levels in the blood and causes a louder "knock." Eventually, the pancreas produces far more insulin than normal and the muscles continue to be resistant to the knock. As long as one can produce enough insulin to overcome this resistance, blood glucose levels remain normal. Once the pancreas is no longer able to keep up, blood glucose starts to rise, initially after meals, eventually even in the fasting state. Type 2 diabetes is now overt.

Kidney: One of a pair of organs located in the right and left side of the abdomen which clear "poisons" from the blood, regulate acid concentration and maintain water balance in the body by excreting urine. The kidneys are part of the urinary tract. The urine then passes through connecting tubes called "ureters" into the bladder. The bladder stores the urine until it is released during urination.


See the entire definition of Kidney

Laboratory: A place for doing tests and research procedures and preparing chemicals, etc. Although "laboratory" looks very like the Latin "laboratorium" (a place to labor, a work place), the word "laboratory" came from the Latin "elaborare" (to work out, as a problem, and with great pains), as evidenced by the Old English spelling "elaboratory" designating "a place where learned effort was applied to the solution of scientific problems."

Magnetic resonance imaging: A special radiology technique designed to image internal structures of the body using magnetism, radio waves, and a computer to produce the images of body structures. In magnetic resonance imaging (MRI), the scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is inserted into the magnet. The magnet creates a strong magnetic field that aligns the protons of hydrogen atoms, which are then exposed to a beam of radio waves. This spins the various protons of the body, and they produce a faint signal that is detected by the receiver portion of the MRI scanner. A computer processes the receiver information, and an image is produced. The image and resolution is quite detailed and can detect tiny changes of structures within the body, particularly in the soft tissue, brain and spinal cord, abdomen and joints.
See the entire definition of Magnetic resonance imaging

Marker: A piece of DNA that lies on a chromosome so close to a gene that the marker and the gene are inherited together. A marker is thus an identifiable heritable spot on a chromosome. A marker can be an expressed region of DNA (a gene) or a segment of DNA with no known coding function. All that matters is that the marker can be detected and trailed.
See the entire definition of Marker back to top

Menstrual: Pertaining to menstruation (the menses), as in last menstrual period, menstrual cramps, menstrual cycle, and premenstrual syndrome. From the Latin menstrualis, from mensis meaning month.

Menstruation: The periodic blood that flows as a discharge from the uterus. Also called menorrhea, the time during which menstruation occurs is referred to as menses. The menses occurs at approximately 4 week intervals to compose the menstrual cycle.

Metabolic: Relating to metabolism, the whole range of biochemical processes that occur within us (or any living organism). Metabolism consists of anabolism (the buildup of substances) and catabolism (the breakdown of substances).
See the entire definition of Metabolic

Metabolic syndrome: A constellation of conditions that place people at high risk for coronary artery disease. These conditions include type 2 diabetes, obesity, high blood pressure, and a poor lipid profile with elevated LDL ("bad") cholesterol, low HDL ("good") cholesterol, elevated triglycerides. All of these conditions are associated with high blood insulin levels. The fundamental defect in the metabolic syndrome is insulin resistance in both adipose tissue and muscle. Drugs that decrease insulin resistance also usually lower blood pressure and improve the lipid profile.
See the entire definition of Metabolic syndrome

MRI: Abbreviation and nickname for magnetic resonance imaging. For more information, see: Magnetic Resonance Imaging; Paul C. Lauterbur; Peter Mansfield.

Neck: The part of the body joining the head to the shoulders. Also, any narrow or constricted part of a bone or organ that joins its parts as, for example, the neck of the femur bone.

Obese: Well above ones normal weight. A person has traditionally been considered to be obese if they are more than 20 percent over their ideal weight. That ideal weight must take into account the person's height, age, sex, and build.
See the entire definition of Obese

Obesity: The state of being well above one's normal weight.
See the entire definition of Obesity

Oligomenorrhea: A reduction in number of menstrual periods and/or amount of menstrual flow.

Ovarian: Of or pertaining to the ovary.

Ovary: The female gonad, the ovary is one of a pair of reproductive glands in women. They are located in the pelvis, one on each side of the uterus. Each ovary is about the size and shape of an almond. The ovaries produce eggs (ova) and female hormones. During each monthly menstrual cycle, an egg is released from one ovary. The egg travels from the ovary through a fallopian tube to the uterus. The ovaries are the main source of female hormones, which control the development of female body characteristics, such as the breasts, body shape, and body hair. They also regulate the menstrual cycle and pregnancy.

Ovulation: The release of the ripe egg from the ovary. The egg is released when the cavity surrounding it (the follicle) breaks open in response to a hormonal signal. Ovulation occurs around fourteen or fifteen days from the first day of the woman's last menstrual cycle. When ovulation occurs, the ovum moves into the fallopian tube and becomes available for fertilization.

PCOS: Polycystic ovary syndrome.

Pigmentation: The coloring of the skin, hair, mucous membranes, and retina of the eye.
See the entire definition of Pigmentation

Pituitary: 1. As an adjective, pertaining to the pituitary gland or its hormonal secretions. 2. As a noun, the pituitary gland itself.
See the entire definition of Pituitary back to top

Pituitary gland: The main endocrine gland. It is a small structure in the head. It is called the master gland because it produces hormones that control other glands and many body functions including growth. The pituitary consists of the anterior and posterior pituitary.
See the entire definition of Pituitary gland

Polycystic ovarian syndrome: Abbreviated PCOS. Polycystic ovarian syndrome is a condition in women characterized by irregular or no menstrual periods, acne, obesity, and excess hair growth. PCOS is a disorder of chronically abnormal ovarian function and hyperandrogenism (abnormally elevated androgen levels). It affects 5%-10% of women of reproductive age. PCOS is also called the Stein-Leventhal syndrome.
See the entire definition of Polycystic ovarian syndrome

Potassium: The major positive ion (cation) found inside of cells. The chemical notation for potassium is K+.
See the entire definition of Potassium

Pregnancy: The state of carrying a developing embryo or fetus within the female body. This condition can be indicated by positive results on an over-the-counter urine test, and confirmed through a blood test, ultrasound, detection of fetal heartbeat, or an X-ray. Pregnancy lasts for about nine months, measured from the date of the woman's last menstrual period (LMP). It is conventionally divided into three trimesters, each roughly three months long.
See the entire definition of Pregnancy

Pregnant: The state of carrying a developing fetus within the body.
See the entire definition of Pregnant

Primary amenorrhea: Absence of menstruation. Amenorrhea is conventionally divided into primary and secondary amenorrhea. With primary amenorrhea, menstruation never takes place. It fails to occur at puberty. With secondary amenorrhea, menstruation starts but then stops. The absence of menstruation during pregnancy is a form of physiologic amenorrhea, physiologic in the sense that it is completely normal and is not caused by anything pathologic. Amenorrhea during lactation is another type of physiologic amenorrhea. The word "amenorrhea" is compounded from three Greek roots "a-", no + "men", month + "rhoia", flow = no monthly flow. Amenorrhea is less commonly called amenia.

Progesterone: A female hormone and the principal progestational hormone that is made mainly by the corpus luteum in the ovary and by the placenta. Progesterone prepares the lining (endometrium) of the uterus (the womb) to receive and sustain the fertilized egg and so permits pregnancy. Similarly refers to synthetic versions of the hormone. Also known as progestational hormone.

Prolactin: A hormone secreted by the pituitary gland. Prolactin stimulates lactation (milk production). It also has many other functions, including essential roles in the maintenance of the immune system.
See the entire definition of Prolactin

Protein: A large molecule composed of one or more chains of amino acids in a specific order determined by the base sequence of nucleotides in the DNA coding for the protein.
See the entire definition of Protein

Radiation: 1. Rays of energy. Gamma rays and X-rays are two of the types of energy waves often used in medicine. 2. The use of energy waves to diagnose or treat disease. See also: Irradiation.

Resistance: Opposition to something, or the ability to withstand it. For example, some forms of staphylococcus are resistant to treatment with antibiotics.

Risk factor: Something that increases a person's chances of developing a disease.

Scan: As a noun, the data or image obtained from the examination of organs or regions of the body by gathering information with a sensing device.
See the entire definition of Scan

Secondary amenorrhea: The abnormal cessation of menstruation. Amenorrhea is conventionally divided into primary and secondary . With primary amenorrhea, menstruation never takes place. It fails to occur at puberty. With secondary amenorrhea, menstruation starts but then stops. The absence of menstruation during pregnancy is a form of physiologic amenorrhea, physiologic in the sense that it is completely normal and is not caused by anything pathologic. Amenorrhea during lactation is another type of physiologic amenorrhea. The word "amenorrhea" is compounded from three Greek roots "a-", no + "men", month + "rhoia", flow = no monthly flow. Amenorrhea is less commonly called amenia.

Serum: The clear liquid that can be separated from clotted blood. Serum differs from plasma, the liquid portion of normal unclotted blood containing the red and white cells and platelets. It is the clot that makes the difference between serum and plasma.
See the entire definition of Serum back to top

Stage: As regards cancer, the extent of a cancer, especially whether the disease has spread from the original site to other parts of the body. See also: Staging.

Stein-Leventhal syndrome: A hormonal problem that causes women to have various symptoms, including irregular or no menstruation, acne, obesity, and excess hair growth. Women with PCO do not ovulate (release an egg for fertilization) every month. They are at a higher risk for high blood pressure, diabetes, heart disease, and cancer of the uterus (endometrial cancer). Much of this risk can be reversed by exercise and weight loss. Medication is generally prescribed to induce regular menstruation, reducing the cancer risk. For acne and excess hair growth, the diuretic medication spironolactone (brand name: Aldactazide) can help. Clomiphene (brand name: Clomid) can be used to induce ovulation if pregnancy is desired. A type of surgery called a wedge resection, in which a piece of the ovary is removed, seems to help some women. No one is sure what causes PCO, but the ovaries of women with PCO contain a number of small cysts.
See the entire definition of Stein-Leventhal syndrome

Syndrome: A set of signs and symptoms that tend to occur together and which reflect the presence of a particular disease or an increased chance of developing a particular disease.
See the entire definition of Syndrome

Testosterone: A "male hormone" -- a sex hormone produced by the testes that encourages the development of male sexual characteristics, stimulates the activity of the male secondary sex characteristics, and prevents changes in them following castration. Chemically, testosterone is 17-beta-hydroxy-4-androstene-3-one.
See the entire definition of Testosterone

Therapy: The treatment of disease.
See the entire definition of Therapy

Thyroid: 1. The thyroid gland. Also, pertaining to the thyroid gland. 2. A preparation of the thyroid gland used to treat hypothyroidism. 3. Shaped like a shield. (The thyroid gland was so-named by Thomas Wharton in 1656 because it was shaped like an ancient Greek shield.)
See the entire definition of Thyroid

Thyroid hormone: A chemical substance made by the thyroid gland for export into the bloodstream. The thyroid gland needs iodine to make thyroid hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3).
See the entire definition of Thyroid hormone

Tomography: The process for generating a tomogram, a two-dimensional image of a slice or section through a three-dimensional object. Tomography achieves this remarkable result by simply moving an x-ray source in one direction as the x-ray film is moved in the opposite direction during the exposure to sharpen structures in the focal plane, while structures in other planes appear blurred. The tomogram is the picture; the tomograph is the apparatus; and tomography is the process.
See the entire definition of Tomography

Triglycerides: The major form of fat stored by the body. A triglyceride consists of three molecules of fatty acid combined with a molecule of the alcohol glycerol. Triglycerides serve as the backbone of many types of lipids (fats). Triglycerides come from the food we eat as well as from being produced by the body.
See the entire definition of Triglycerides

Type 2 diabetes: See Diabetes, type 2.

Ultrasound: High-frequency sound waves. Ultrasound waves can be bounced off of tissues using special devices. The echoes are then converted into a picture called a sonogram. Ultrasound imaging, referred to as ultrasonography, allows physicians and patients to get an inside view of soft tissues and body cavities, without using invasive techniques. Ultrasound is often used to examine a fetus during pregnancy. There is no convincing evidence for any danger from ultrasound during pregnancy.

Uterine bleeding: See: Menstruation. See also Menometrorrhagia; Menorrhagia; Metrorrhagia.

Uterine cancer: Cancer of the womb (the uterus). Also called endometrial cancer. Cancer of the uterus occurs most often in women between the ages of 55 and 70 years. It accounts for about 6% of cancer in women. Women at elevated risk for uterine cancer include those who are obese, who have few or no children, who began menstruating at a young age, who had a late menopause, and women of high socioeconomic status. It is thought that most of these risk factors are related to hormones, especially excess estrogen.


See the entire definition of Uterine cancer

Uterine lining: The inner layer of the uterus (womb); the cells that line the womb; anatomically termed the endometrium.
See the entire definition of Uterine lining

Uterus: The uterus (womb) is a hollow, pear-shaped organ located in a woman's lower abdomen between the bladder and the rectum. The narrow, lower portion of the uterus is the cervix; the broader, upper part is the corpus. The corpus is made up of two layers of tissue.


See the entire definition of Uterus back to top

Weight loss: Weight loss is a decrease in body weight resulting from either voluntary (diet, exercise) or involuntary (illness) circumstances. Most instances of weight loss arise due to the loss of body fat, but in cases of extreme or severe weight loss, protein and other substances in the body can also be depleted. Examples of involuntary weight loss include the weight loss associated with cancer, malabsorption (such as from chronic diarrheal illnesses ), and chronic inflammation (such as with rheumatoid arthritis).

  • Related Diseases & Conditions

    • High Blood Pressure
      • High blood pressure, also known as hypertension, is a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90. There are two causes of high blood pressure, primary and secondary. Primary high blood pressure is much more common that secondary and its basic causes or underlying defects are not always known. It is known that a diet high in salt increases the risk for high blood pressure, as well as high cholesterol. Genetic factors are also a primary cause. Secondary high blood pressure is generally caused by another condition such as renal hypertension, tumors, and other conditions. Treatment for high blood pressure is generally lifestyle changes and if necessary, diet.
    • Acne (Pimples)
      • Acne is a localized skin inflammation as a result of overactivity of oil glands at the base of hair follicles. This inflammation, depending on its location, can take the form of a superficial pustule (contains pus), a pimple, a deeper cyst, congested pores, whiteheads, or blackheads. Treatments vary depending on the severity of the acne.
    • Ovarian Cysts
      • Ovarian cysts are fluid-filled, sac-like structures within an ovary. Causes of ovarian cysts are numerous. Symptoms of an ovarian cysts may be pain in the belly or pelvis. Treatment of an ovarian cysts depends on type of cyst.
    • Cysts
      • Cysts are saclike structures that can occur throughout the body and usually contain a semisolid, liquid, or gaseous substance. Infections, tumors, genetic conditions, chronic inflammatory conditions, and wear and tear can cause cysts. Though some cysts may be palpable, others may not produce any symptoms. Treatment depends upon the location and cause of the cyst.
    • Cholesterol
      • Cholesterol is naturally produced by the body, and is a building block for cell membranes and hormones. Low-density lipoprotein (LDL) cholesterol is the "bad" cholesterol, conversely, high-density lipoprotein (HDL) cholesterol is the "good" cholesterol. High cholesterol treatment includes lifestyle changes (diet and exercise), and medications such as statins, bile acid resins, and fibric acid derivatives.
    • Vaginal Bleeding
      • Normal vaginal bleeding (menorrhea) occurs through the process of menstruation. Abnormal vaginal bleeding in women who are ovulating regularly most commonly involves excessive, frequent, irregular, or decreased bleeding. Causes of abnormal may arise from a variety of conditions.
    • Miscarriage
      • A miscarriage is any pregnancy that ends spontaneously before the fetus can survive. Miscarriage usually occurs before the 13th week of pregnancy. The cause of a miscarriage cannot always be determined. The most common causes of a miscarriage in the first trimester are collagen vascular disease (lupus), hormonal problems, diabetes, chromosomal abnormalities, and congenital abnormalities of the uterus.
    • Insulin Resistance
      • Insulin resistance is the diminished ability of cells to respond to the action of insulin in transporting glucose (sugar) from the bloodstream into muscle and other tissues. Causes of insulin can include conditions such as stress, obesity, metabolic syndrome, and steroid use. Some of the risk factors for insulin resistance include fatty liver, heart disease, strokes, peripheral vascular disease, high cholesterol, and smoking. Treatment for insulin resistance are lifestyle changes and if necessary, medication.
    • Cushing's Syndrome
      • Cushing's syndrome, sometimes referred to as hypercortisolism, is a hormonal disorder caused by prolonged exposure to high levels of the hormone cortisol. Symptoms may include obesity, thinning arms and legs, a rounded face, and increased fat around the neck. Some causes of Cushing's syndrome is from taking glucocorticoid hormones such as prednisone for inflammatory diseases. Treatment for Cushing's syndrome depends on the cause.
    • Obesity
      • Obesity is the state of being well above one's normal weight. A person has traditionally been considered to be obese if they are more than 20 percent over their ideal weight. That ideal weight must take into account the person's height, age, sex, and build.
    • Metabolic Syndrome
      • The main features of metabolic syndrome include insulin resistance, hypertension (high blood pressure), cholesterol abnormalities, and an increased risk for clotting. Patients are most often overweight or obese. Lifestyle modification such as the Mediterranean diet, exercise, and quitting smoking are the preferred treatment of metabolic syndrome.
    • Dandruff (Seborrhea)
      • Dandruff (seborrhea) is a skin disorder that results from neither too much moisture nor too much oil. Dandruff can be treated with shampoos that contain tar, salicylic acid, zinc, selenium sulfide, or ketoconazole.
    • Infertility
      • Infertility is the diminished ability to conceive a child. The primary cause of infertility in men is a sperm disorder. In women, the primary cause of infertility is an ovulation disorder. Most forms of infertility can be treated. Conventional infertility therapies include drugs or surgery.
    • Amenorrhea
      • Amenorrhea is a condition in which there is an absense of menstrual periods in a woman. There are two types of amenorrhea, 1) primary and 2) secondary. Treatment of amenorrhea depends on the type (primary or secondary). In prmiray, surgery may be an option and in secondary amenorrhea medication or lifestyle changes may be treatment options.
    • Diabetes Insipidus
      • Diabetes insipidus is a condition in which the patient has frequent urination. Symptoms of diabetes insipidus include irritable, listless, fever, vomiting, or diarrhea due to the loss of large volumes of urine. There are three types of diabetes insipidus, central, nephrogenic, dipsogenic, and gestational. Treatment depends upon the type of diabetes insipidus.
    • Menstruation
      • Menstruation (menstrual cycle) is also referred to as a "period." When a woman menstruates, the lining of the uterus is shed. This shedding of the uterine linking is the menstrual blood flow. The average menstrual cycle is 28 days. There can be problems with a woman's period, including heavy bleeding, pain, or skipped periods. Causes of these problems may be amenorrhea (lack fo a period), menstrual cramps (dysmenorrhea), or abnormal vaginal or uterine bleeding.

What is normal vaginal bleeding?

Normal vaginal bleeding is the periodic blood that flows as a discharge from the woman's uterus. Normal vaginal bleeding is also called menorrhea. The process by which menorrhea occurs is called menstruation.

Normal vaginal bleeding occurs as a result of cyclic hormonal changes. The ovaries are the main source of female hormones, which control the development of female body characteristics such as the breasts, body shape, and body hair. The hormones also regulate the menstrual cycle. The ovary, or female gonad, is one of a pair of reproductive glands in women. They are located in the pelvis, one on each side of the uterus. Each ovary is about the size and shape of an almond. The ovaries produce eggs (ova) and female hormones. During each monthly menstrual cycle, an egg is released from one ovary. The egg travels from the ovary through a Fallopian tube to the uterus.
