Hypermobility syndrome Syndrome of arthralgia associated with joint hypermobility.
RELATED TERMS--------------------------------------
Syndrome
A grouping of signs and symptoms, based on their frequent co-occurrence, that may suggest a common underlying pathogenesis, course, familial pattern, or treatment selection.
Arthralgia
Joint pain. There may not be any outward evidence of a joint abnormality.

Excessive acidity.
Hyperacuity

Hyperacusis
Inordinate sensitivity to sounds; it may be on an emotional or an organic basis.
Hyperbaric
Characterized by greater-than-normal pressure. Hyperbaric oxygen is a therapeutic treatment designed to increase blood oxygen by delivering oxygen in a chamber room with greater-than-normal pressure.

Hypercomplex cells
A third category of striate cells identified by Hubel and Wiesel that have since been classified as subsets of simple and complex cells. They posses inhibitory zones at one or both ends of oriented excitatory regions, thereby responding to bars of preferred orientation only if they are not too long.
Hyperemesis gravidarum
Excessive morning sickness.
Hyperemia
increased blood flow; may cause dental sensitivity to temperature and sweets; may precede an abscess.

Hyperglicemia
A condition in which the blood sugar is higher than normal.
Hyperglycemia
Too high a level of glucose (sugar) in the blood; a sign that diabetes is out of control. Many things can cause hyperglycemia. It occurs when the body does not have enough insulin or cannot use the insulin it does have to turn glucose into energy. Signs of hyperglycemia are a great thirst, a dry mouth, and a need to urinate often. For people with Type 1 diabetes, hyperglycemia may lead to diabetic ketoacidosis.
Hyperglycemic
High blood sugar.
Hyperglycemic hyperosmolar nonketotic syndrome
See Nonketotic Coma.
Hyperinsulinemia
The excess production of insulin. This is usually a consequence of insulin resistance in which the cells do not respond to insulin to reduce blood glucose levels.
Hyperinsulinism
Too high a level of insulin in the blood. This term most often refers to a condition in which the body produces too much insulin. Researchers believe that this condition may play a role in the development of noninsulin-dependent diabetes and in hypertension.
Hyperlipidemia
Too high a level of fats (lipids) in the blood.
Hyperopia
Hyperopia (or more rarely, hypermetropia), also known as farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves towards the eye, the eye must increase its power to keep the image on the retina.
Hyperorgasmia
The phenomenon of having an inordinate number of orgasms within a given period, as compared with a given criterion standard.
Hyperparathyroidism
Excessive secretion of parathyroid hormone from the parathyroid glands, which are situated alongside the thyroid gland in the throat, and which play a role in regulating the amount of calcium in blood and body tissues.
Hyperphilia
A condition or syndrome, variable in etiology and diagnosis, of being sexuoerotically above standard or inordinate, particularly with respect to some aspect of genital functioning prior to and at the acceptive phase. The condition of being supranormal in sexual and genital responsiveness or frequency.
Hyperphoria
A tendency for one eye to drift upward. A vertical type of muscle imbalance between the eyes.
Hyperpigmentation
Post-inflammatory hyperpigmentation is an excessive skin darkening at places where the skin was inflamed.
Hyperplasia
An increase in the number of cells in a tissue or organ, usually as a physiologic response to a stimulus.
Hypersensitivity
State of reactivity to antigen that is greater than normal for the antigenic challenge; hypersensitivity is the same as allergy and denotes a deleterious outcome rather than a protective one.
Hypersomnia
Excessive difficulty maintaining an alert awake state during the day, or undesired daytime sleep episodes. sleepiness, as evidenced by prolonged nocturnal sleep, ideas of reference The feeling that casual incidents and external events have a particular and unusual meaning that is specific to the person.

Systolic blood pressure from 140 to 159 mm HG is considered mild hypertension; 160–179, moderate hypertension; and 180 or greater, severe hypertension.

HPV
HPV is an acronym for the Human Papilloma Virus, a virus which is known to cause warts. HPV has also been associated with various precancerous and malignant disorders. It is most common sexually transmitted infection, affecting about 80 percent of all adults at one time or another by the time they are 50. HPV is the name for a group of viruses that includes more than 100 types. About 30 percent are transmitted primarily through sexual intercourse or intimate skin-to-skin contact. Of these, most are considered "low-risk," which means they cannot cause cancer. However, about a dozen or so are "high risk," which means they can lead to cancer if they are not fought off by the immune system.
