Polycythemia (High Red Blood Cell Count) Topic Guide
Polycythemia: Polycythemia is a condition in which there is an increased number of red blood cells in the blood. There are two types of polycythemia; 1) primary polycythemia and 2) secondary polycythemia. The two main conditions of primary polycythemia are polycythemia vera (PV) and primary familial and congenital polycythemia (PFCP). Causes of secondary polycythemia include conditions as a result of chronic hypoxia such as COPD, emphysema, chronic bronchitis, pulmonary hypertension, congestive heart failure, obstructive sleep apnea, and certain cancers. Examples of symptoms of polycythemia include easy bruising or bleeding, blood clot formation, headache, itching, and fatigue. Treatment for polycythemia depends on the cause.
