  • Hysteropexy

    Stitching the womb to the abdominal wall to prevent its downward displacement.  

  • Hysterocleisis

    Surgical closure of the passage from the womb to the vagina at the mouth of the womb.  

  • Hypsarrhythmia

    An abnormal and chaotic pattern of brain activity, demonstrated by encephalography, that is sometimes associated with infantile spasms. An abnormal electroencephalographic pattern of persistent generalized slow waves and very high voltage. Clinically it is often associated with infantile spasm and progressive mental deterioration.  

  • Hypoxemia

    The presence in the blood of an abnormally low concentration of oxygen, usually as a result of inadequate uptake of oxygen in the lungs because of lung disease. Decreased oxygen tension (oxygen concentration) of arterial blood, measured by arterial oxygen partial pressures (Pa02) values. It is sometimes associated with decreased oxygen content.  

  • Hyposthenuria

    The secretion of urine of low specific gravity. The inability to concentrate the urine occurs in patients at the final stage of chronic renal failure.  

  • Hypoprothrombinemia

    A deficiency of the clotting factor prothrombin in the blood, which results in an increased tendency to bleed. It may occur as an inherited defect, as the result of liver disease, vitamin K deficiency, or anticoagulant treatment. A deficiency of blood clotting factor II (prothrombin) in the blood.  

  • Hypomenorrhea

    The release of an abnormally small quantity of blood at menstruation. The duration of bleeding may be normal or less than normal. A deficient amount of menstrual flow, but with regular periods. A condition where the menstrual cycle is extended and frequently irregular because of ovarian dysfunction. There’s minimal blood loss, and the time between…

  • Hypoidrosis

    The production of an abnormally small amount of sweat relative to the environmental temperature, bodily activity, or other relevant circumstances.  

  • Hypofibrinogenemia

    A deficiency of the clotting factor fibrinogen in the blood, which results in an increased tendency to bleed. It may occur as an inherited disorder in which either production of fibrinogen is impaired or the fibrinogen produced does not function in the normal way (dysfibrinogenemia). Alternatively, it may be acquired.  

  • Hypoderma

    A genus of nonbloodsucking beelike insects, the warble flies, widely distributed in Europe, North America, and Asia. Cattle are the usual hosts for the parasitic maggots, but rare and accidental infections of man have occurred, especially in farm workers. The maggots migrate beneath the skin surface producing an inflamed linear lesion similar to that of…
