Polycythemia, also called erythrocytosis, is an abnormal increase in the number of red blood cells produced by the bone marrow. The extra numbers of red blood cells cause blood to thicken and may increase the risk of blood clots that may cause heart attacks or strokes.
Treatment for polycythemia sometimes involves removing red blood cells (much like donating blood) from the blood. Treatment may also involve taking medicines.
