Polycythemia (say: "polly-sigh-thee-me-ah") vera (PV) is a disease in which your body makes too many red blood cells. Your blood may become too thick. This causes serious health problems. PV increases the risk of abnormal blood clots, which could lead to a stroke. This disease occurs most often in people who are about 60 years old or older.
