Polycythemia Vera is a condition where the body produces too many red blood cells. This thickening of the blood can increase the risk of clots and requires careful management.
Treatment and Care Options
Treatment for Polycythemia Vera aims to control the excessive blood cell counts and manage symptoms, as there is currently no cure. Treatment plans are highly individualized and managed by a hematologist. At-home care focuses on monitoring and adherence to medication.
Primary Treatments include:
- Medications: Drugs may be prescribed to reduce red blood cell counts (erythropoiesis-stimulating agents) or suppress the overactive bone marrow.
- Blood Transfusions: If the blood becomes dangerously thick or counts are severely low, transfusions may be necessary to prevent clots.
- Splenectomy (Spleen Removal): In some cases, removing the spleen can help reduce the blood volume and circulating cells.
Supportive Care: Patients must maintain a healthy lifestyle, manage hydration, and take all prescribed medications exactly as directed to prevent blood clotting and related complications.
What Causes Polycythemia Vera?
Polycythemia Vera (PV) is classified as a chronic myeloproliferative neoplasm. This means it is a blood disorder where the bone marrow makes too many blood cells. The exact cause is often related to a genetic mutation, specifically affecting the JAK2 gene.
- Genetic Mutation: A mutation in the JAK2 gene is frequently involved, signaling the bone marrow to overproduce various blood components, especially red cells.
- Overproduction of Blood Cells: The disorder itself is characterized by the bone marrow's inability to regulate the normal count of red blood cells, platelets, and white blood cells.
