What is erythremia?

Erythremia, also known as polycythemia vera, is a blood disorder characterized by an increased number of red blood cells in the bloodstream. This condition can lead to thickened blood, raising the risk of blood clots, strokes, and other cardiovascular issues. Erythremia is often associated with mutations in the JAK2 gene and may present symptoms such as headaches, dizziness, and a ruddy complexion. Treatment typically focuses on reducing red blood cell mass and managing symptoms.
