What is polycythemia vera?
Polycythemia vera is a rare blood condition where the body produces too many blood cells, especially red blood cells. This causes the blood to become thicker than normal, which can slow down circulation. When blood doesn’t flow easily, it can increase the risk of clots and other serious complications.
This condition is usually caused by a genetic change that happens during a person’s lifetime. It is not typically passed down through families. The exact reason this mutation occurs is often unclear.
Symptoms
Polycythemia vera develops gradually, and symptoms can vary from person to person. Some people may not notice signs right away.
Common symptoms include:
- Ongoing fatigue or low energy
- Headaches or dizziness
- Shortness of breath
- Blurred or double vision
- Itching after a warm shower or bath
- Redness or warmth in the face
- Easy bruising or bleeding (such as nosebleeds or gum bleeding)
- Night sweats
- Numbness or tingling in the hands and feet
How is it diagnosed?
To diagnose polycythemia vera, your provider will begin with a physical exam and a review of your health history. Blood tests are used to measure red blood cell levels and check for abnormalities.
Additional testing may include:
- Genetic testing to look for specific mutations
- Bone marrow biopsy to evaluate how blood cells are being made
These tests help confirm the diagnosis and rule out other conditions.
How is it treated?
While there is no cure for polycythemia vera, treatment can help manage symptoms and lower the risk of complications.
Common treatment options include:
- Phlebotomy: Removing small amounts of blood to reduce thickness
- Medications: Drugs that slow blood cell production or improve circulation
- Low-dose aspirin: Helps reduce the risk of blood clots
Your care plan will depend on your overall health and the severity of your condition.
Living with polycythemia vera
Many people live full lives with proper treatment. Staying active, drinking enough water, and avoiding extreme temperatures can help improve blood flow and reduce symptoms. Regular follow-up care is important to monitor your condition.
