Erythrocytosis is a rare inherited blood disorder where the body produces too many red blood cells. The excess red blood cells increase the risk for blood clots which could prevent blood flow to major organs such as the heart, lungs, or brain. While the prevalence of erythrocytosis is unknown, researchers found the cause of one type to be genetic mutations involving one or more genes. Erythrocytosis can sometimes lead to other more serious conditions such as polycythemia vera. Polycythemia vera is a genetically acquired blood disorder in which your body makes too many blood cells.
