erythrocytosis

 [ĕ-rith″ro-si-to´sis]
increase in the total red blood cell mass secondary to any of a number of nonhematogenic systemic disorders in response to a known stimulus (secondary polycythemia), in contrast to primary polycythemia (polycythemia vera).
stress erythrocytosis an apparent polycythemia seen in active, anxiety-prone persons, resulting from diminished plasma volume.

erythrocytosis

[erith′rōsītō′sis]
Etymology: Gk, erythros + kytos + osis, condition
an abnormal increase in the number of circulating red cells. See also polycythemia.

(ĕ-rith'rō-sī-tō'sis)
Polycythemia, especially that which occurs in response to some known stimulus.

erythrocytosis

An increase in the number of red blood cells in a unit volume of blood. This occurs essentially as a response to an inadequate supply of oxygen to the tissues. It occurs at high altitudes, in smokers, in heart or lung disease and in the presence of certain tumours that produce substances that stimulate red cell production. Erythrocytosis also occurs in the condition of primary POLYCYTHAEMIA.

Erythrocytosis

Increased production of red blood cells.

erythrocytosis (ərith´rōsītō´sis),

n (secondary polycythemia) an increased circulating red blood cell mass resulting from compensatory effort to meet reduced oxygen content. May be seen in persons living at high altitudes, as well as in persons with emphysema, pulmonary insufficiency, and heart failure.

erythrocytosis

increase in the total red cell mass secondary to any of a number of nonhematogenic systemic disorders in response to a known stimulus (secondary polycythemia), in contrast to primary polycythemia (polycythemia vera).

erythrocytosis stimulating factor
a lipid isolated from the plasma of anemic animals; distinct from erythropoietin, causes production of microcytes without increasing hemoglobin. Its role in disease is unknown.
stress erythrocytosis
an apparent polycythemia resulting from diminished plasma volume.
