OVERVIEW

What is polycythemia vera?

Polycythemia vera (PV) is a rare disease in which your body makes too many red blood cells. Your blood may become too thick. This causes serious health problems. PV increases the risk of abnormal blood clots, which could lead to a stroke. This disease occurs most often in people who are about 60 years old or older.

SYMPTOMS

What are the symptoms of PV?

In its early stages, PV usually doesn’t cause any symptoms. As the disease progresses, symptoms include:

• Shortness of breath
• Dizziness
• Itchy or flushed skin
• Fatigue
• Headaches
• A tingling or burning sensation in the hands and feet

CAUSES & RISK FACTORS

What causes PV?

PV begins in the bone marrow. Bone marrow is the soft tissue inside bones that makes blood cells. When bone marrow makes too many red blood cells, the result is PV.

DIAGNOSIS & TESTS

How will my healthcare provider know if I have PV?

If you have symptoms of PV, your healthcare provider may examine you and order blood tests. Sometimes the disease may be found by accident when you have blood work done for another reason. Your healthcare provider will want you to see a hematologist (a healthcare provider who treats blood disorders) to make the diagnosis. If they suspect you may have PV, you may need to have a bone marrow biopsy. This is when a small part of your bone marrow is removed and examined for signs of PV.

PREVENTION

Can polycythemia vera be prevented or avoided?

PV can’t be prevented or avoided.

TREATMENT

There is no single treatment for PV. Healthcare providers must adjust the treatment for each patient. Treatment may include a phlebotomy. In this treatment, some of your blood is removed to help keep the number of red blood cells down and lower the risk of blood clots. Treatment may also include a medicine that keeps the bone marrow from making too many red blood cells or to help reduce the risk of blood clots. Healthcare providers can also treat the itchy skin and burning pain that you may experience.

There is currently no cure for PV. The goal is to make your life better by treating the symptoms and helping you to live longer.
