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.
