What it means

Polycythemia is a condition in which the body produces too many red blood cells, making the blood thicker than normal. Polycythemia vera is the primary form, caused by a genetic mutation in the bone marrow. Secondary polycythemia can result from chronic low oxygen levels (such as in sleep apnea or living at high altitude) or other underlying conditions. Thickened blood increases the risk of blood clots, stroke, and heart attack. Symptoms may include headaches, dizziness, itching after bathing, and red skin. Treatment includes phlebotomy (removing blood), aspirin, and medications to reduce blood cell production.
