Relative polycythemia

This state is characterized by increase in OOE of a venous blood with a normal lump of erythrocytes. The relative polycythemia occurs at two groups of patients. At representatives of the first group the relative polycythemia develops sharply and is caused by dehydration. In the second group which is usually made by men of middle and advanced age the origin of a relative polycythemia is not clear. At these patients increase in OOE of a venous blood is connected with hypertensia, thromboses, increase in serum of levels of cholesterol and uric acid. At such patients the plethora and excess body weight is often observed, they are subject to stressful reactions, are uneasy, easily fall into a condition of a nervous tension. Besides, they have headaches, dizzinesses, short wind, perspiration and abdominal pains. Such signs of an Osler's disease as a splenomegaly, a thrombocytosis and the increased level of an alkaline phosphatase of leukocytes are not observed.

Clinical value of the increased OOE level of a venous blood is not clear that complicates elaboration of tactics of maintaining such patients.
Long supervision over the patients who are not receiving any treatment showed that the OOE level at them does not increase and characteristic signs of an Osler's disease do not arise. At the same time some doctors treat such patients bloodletting in spite of the fact that this method does not prevent development of thromboses and embolisms. Certainly, those patients who have excess body weight have a hypertension or smoke, have to receive the corresponding recommendations or treatment.

This state was given different names: pseudo-polycythemia, stressful polycythemia, Gaysbek's illness, high-quality hyperglobulia. Not absolutely it is clear, whether mean these names various diseases or the same nosological unit. There is an opinion that all symptoms of a relative polycythemia are in essence not connected with each other.
