Hyperemia
|
D006940 |
[The presence of an increased amount of blood in a body part or an organ leading to congestion or engorgement of blood vessels. Hyperemia can be due to increase of blood flow into the area (active or arterial), or due to obstruction of outflow of blood from the area (passive or venous).

Hypereosinophilic Syndrome
|
D017681 |
[A heterogeneous group of disorders with the common feature of prolonged eosinophilia of unknown cause and associated organ system dysfunction, including the heart, central nervous system, kidneys, lungs, gastrointestinal tract, and skin. There is a massive increase in the number of EOSINOPHILS in the blood, mimicking leukemia, and extensive eosinophilic infiltration of the various organs.

Hyperesthesia

D006941 |
[Increased sensitivity to cutaneous stimulation due to a diminished threshold or an increased response to stimuli.

|
Hyperferritinemia
|
D000085583 |
[A finding of elevated serum level of FERRITIN. It is often associated with IRON OVERLOAD, repeated blood transfusions, malignancy, iron metabolic syndromes, virus infection, liver injury or dysfunction, and renal failure. Hyperferritinemia in iron metabolic syndromes (e.g., Still's diseases, and HEMOPHAGOCYTIC SYNDROME) is referred to as dysmetabolic hyperferritinemia.

Hypergammaglobulinemia
|
D006942 |
[An excess of GAMMA-GLOBULINS in the serum due to chronic infections or PARAPROTEINEMIAS.

|
Hyperglycemia
|
D006943 |

Hyperglycemic Hyperosmolar Nonketotic Coma
|
D006944 |
[A serious complication of TYPE 2 DIABETES MELLITUS. It is characterized by extreme HYPERGLYCEMIA; DEHYDRATION; serum hyperosmolarity; and depressed consciousness leading to COMA in the absence of KETOSIS and ACIDOSIS.

|
Hyperglycinemia, Nonketotic
|
D020158 |
[An autosomal recessive metabolic disorder caused by deficiencies in the mitochondrial GLYCINE cleavage system.

|
Hypergravity
|
D018471 |
[Condition wherein the force of gravity is greater than or is increased above that on the surface of the earth. This is expressed as being greater than 1 g.
] |
|
Hyperhidrosis
|
D006945 |
[Excessive sweating. In the localized type, the most frequent sites are the palms, soles, axillae, inguinal folds, and the perineal area. Its chief cause is thought to be emotional. Generalized hyperhidrosis may be induced by a hot, humid environment, by fever, or by vigorous exercise.

|
Hyperhomocysteinemia
|
D020138 |
[Condition in which the plasma levels of homocysteine and related metabolites are elevated (>13.9 μmol/l). Hyperhomocysteinemia can be familial or acquired. Development of the acquired hyperhomocysteinemia is mostly associated with vitamins B and/or folate deficiency (e.g., PERNICIOUS ANEMIA, vitamin malabsorption). Familial hyperhomocysteinemia often results in a more severe elevation of total homocysteine and excretion into the urine, resulting in HOMOCYSTINURIA. Hyperhomocysteinemia is a risk factor for cardiovascular and neurodegenerative diseases, osteoporotic fractures and complications during pregnancy.

Hypericum
|
D020902 |
[Genus of perennial plants in the family CLUSIACEAE (sometimes classified as Hypericaceae). Herbal and homeopathic preparations are used for depression, neuralgias, and a variety of other conditions. Hypericum contains flavonoids; GLYCOSIDES; mucilage, TANNINS; volatile oils (OILS, ESSENTIAL), hypericin and hyperforin.

|
Hyperinsulinism
|
D006946 |
[A GLUCOSE-induced HYPERINSULINEMIA, a marker of insulin-resistant state. It is a mechanism to compensate for reduced sensitivity to insulin.
, A syndrome with excessively high INSULIN levels in the BLOOD. It may cause HYPOGLYCEMIA. Etiology of hyperinsulinism varies, including hypersecretion of a beta cell tumor (INSULINOMA); autoantibodies against insulin (INSULIN ANTIBODIES); defective insulin receptor (INSULIN RESISTANCE); or overuse of exogenous insulin or HYPOGLYCEMIC AGENTS.

|
Hyperkalemia
|
D006947 |
[Abnormally high potassium concentration in the blood, most often due to defective renal excretion. It is characterized clinically by electrocardiographic abnormalities (elevated T waves and depressed P waves, and eventually by atrial asystole). In severe cases, weakness and flaccid paralysis may occur. (Dorland, 27th ed)

|
Hyperkeratosis, Epidermolytic
|
D017488 |
[A form of congenital ichthyosis inherited as an autosomal dominant trait and characterized by ERYTHRODERMA and severe hyperkeratosis. It is manifested at birth by blisters followed by the appearance of thickened, horny, verruciform scales over the entire body, but accentuated in flexural areas. Mutations in the genes that encode KERATIN-1 and KERATIN-10 have been associated with this disorder.

|
Hyperkinesis
|
D006948 |
[Excessive movement of muscles of the body as a whole, which may be associated with organic or psychological disorders.
] |
|
Hyperlactatemia
|
D065906 |
[Increase in blood LACTATE concentration often associated with SEPTIC SHOCK; LUNG INJURY; SEPSIS; and DRUG TOXICITY. When hyperlactatemia is associated with low body pH (acidosis) it is LACTIC ACIDOSIS.
] |
|
Hyperlipidemia, Familial Combined
|
D006950 |
[A type of familial lipid metabolism disorder characterized by a variable pattern of elevated plasma CHOLESTEROL and/or TRIGLYCERIDES. Multiple genes on different chromosomes may be involved, such as the major late transcription factor (UPSTREAM STIMULATORY FACTORS) on CHROMOSOME 1.
