Polycythemia vera’s symptoms are mild, and it might not cause symptoms at all until complications develop. The condition develops slowly. The average age at diagnosis is 60, although it can affect people younger than 40 years old.

Red blood cells carry oxygen to the cells of the body to provide them with energy. But when there areexcess red blood cellsin the blood vessels—which occurs with polycythemia vera—blood flow is impaired, oxygen delivery becomes inadequate, and the risk of blood clots increases.

Common symptoms of polycythemia vera include:

Polycythemia vera can cause infrequent symptoms as well, and you can experience any combination of common or rare symptoms intermittently (once in a while) or constantly.

These problems are considered medical emergencies, can rapidly worsen, and may lead to death.

The long-term complications of polycythemia vera include:

These conditions may cause vague symptoms of fatigue, weight loss, and generalized weakness. If you have been diagnosed with polycythemia vera, your doctor may check for complications with periodic blood tests.

If you have symptoms of these cancers, your doctor might order an imaging test or perform a biopsy (removing a tissue sample for further examination in a lab), depending on your symptoms and physical examination.
