Polycythemia is a condition in which there is a net increase in the total circulating erythrocyte (red blood cell) mass of the body.
In primary polycythemia there may be 8 to 9 million and occasionally 11 million erythrocytes per cubic millimeter of blood, and the hematocrit may be as high as 70 to 80%.
Relative polycythemia is an apparent rise of the erythrocyte level in the blood; however, the underlying cause is reduced blood plasma.

The excessive numbers of red blood cells produced in polycythemia increases the volume of blood and makes it thicker so that it flows less easily through small blood vessels.
The excess of red blood cells may be associated with other complications, including stomach ulcers, kidney stones or clotting in veins and arteries, which can cause heart attacks or strokes and can block blood flow to the arms and legs.
Rarely, polycythemia vera progresses to leukemia; certain treatments increase this likelihood.
