No: There are two types of polycythemia. Primary Polycythemia (Polycythemia Vera) is an abnormal proliferation of blood cells, leading to too many red blood cells. It is not caused by any other factor. Secondary Polycythemia is a high red cell count caused by another factor, such as being at altitude, sleep apnea, administration of erythropoietin, or several others. Hope this helps!
