What is polycythemia vera?
Polycythemia vera is a rare blood disorder in which there is an increase in all blood cells, particularly red blood cells. The increase in blood cells makes your blood thicker and can cause problems with blood flow (circulation). This can lead to strokes or tissue and organ damage.
What causes polycythemia vera?
Polycythemia vera is caused by a genetic change (mutation) that develops during your lifetime. It is not an inherited genetic disorder. In most cases it is not known why this happens.
What are the symptoms of polycythemia vera?
When you have more blood and it is thicker than normal, problems can occur. Each person’s symptoms may vary. Symptoms may include:
- Lack of energy (fatigue) or weakness
- Shortness of breath and trouble breathing while lying down
- Vision problems, such as double vision, blurred vision, and blind spots
- Inability to concentrate
- Night sweats
- Face becomes red and warm (flushed)
- Bleeding gums
- Too much menstrual bleeding
- Coughing up blood
- Itchy skin (often after a hot bath)
- High blood pressure
These symptoms may look like other blood disorders or health problems. Always see your healthcare provider for a diagnosis.
How is polycythemia vera diagnosed?
Your healthcare provider will take your health history and give you a physical exam. Your provider may also do blood tests. These tests will check the increased number of red blood cells in your body. They will also check if there are other conditions that could cause your higher red blood cell count.
How is polycythemia vera treated?
Treatment will depend on your symptoms, age, and general health. It will also depend on how severe the condition is.
Treatment may include:
- Phlebotomy. This procedure removes blood from your body. At first this must be done often, such as every week. Once enough blood has been removed to reduce your body's iron stores (needed to make blood quickly), you will not need this done as often.
- Certain medicines, including chemotherapy. The medicines help to stop your bone marrow from making too many blood cells. They also keep your blood flow and blood thickness closer to normal.
What are possible complications of polycythemia vera?
Polycythemia vera can be fatal if not diagnosed and treated. It can cause blood clots resulting in a heart attack, stroke, or pulmonary embolism. Liver and spleen enlargement are other possible complications. In some cases, in can transform into a condition resulting in bone marrow scarring (fibrosis) or leukemia.
Living with polycythemia vera
There is no cure for polycythemia vera. But correct treatment can help to reduce or delay any problems. Work with your healthcare provider to create a treatment plan that fits your needs. You should also be physically active in order to increase your heart rate and improve your blood flow.
Other ways to improve your blood flow include:
- Stretching your legs and ankles
- Staying away from extreme heat
- Drinking plenty of water
This condition can cause circulation problems. So take care of your hands and feet. Protect them from injuries from cold and heat. For example, wear warm gloves and socks during cold weather.
