Polycythemia is a condition characterized by an abnormal increase in the number of red blood cells in the body. This can make the blood thicker and increase the risk of blood clots1. There are two main types of polycythemia:

Primary Polycythemia (Polycythemia Vera)
Cause: A rare, slow-growing blood cancer known as a myeloproliferative neoplasm.

Mechanism: A mutation in the JAK2 gene causes the bone marrow to produce too many red blood cells.

Symptoms: Headaches, dizziness, fatigue, blurred vision, and itchiness, especially after a warm bath or shower.

Treatment: Phlebotomy (removal of blood), medications to reduce blood cell production, and antiplatelet therapy to prevent blood clots.

Secondary Polycythemia
Cause: Due to underlying conditions that lead to low oxygen levels in the body, such as living at high altitudes, chronic lung diseases, or heart defects.

Mechanism: The body compensates for low oxygen levels by producing more red blood cells.

Symptoms: Similar to primary polycythemia, but often related to the underlying condition.

Treatment: Addressing the underlying cause and, in some cases, phlebotomy
