DefinitionBy Mayo Clinic Staff
Essential thrombocythemia is an uncommon disorder in which your body produces too many blood platelets. This condition may cause you to feel fatigued, lightheaded and to experience headaches and vision changes. It also increases your risk of blood clots.
Essential thrombocythemia (throm-boe-sie-THEE-me-uh) is more common in people over age 50 and slightly more common in women. Young people can develop it as well.
Essential thrombocythemia is a chronic disease that has no cure. If you have a mild form of the disease, you may not need treatment. If you have a severe condition, you may need medicine that lowers your platelet count, blood thinners or both.
