Symptoms and causes of polycythemia vera

Polycythemia vera (PV), a rare and chronic blood disorder, is characterized by the excessive production of red blood cells. This disease falls under myeloproliferative neoplasms (MPNs), a group of blood cancers. Although PV primarily affects red blood cells, it can also produce white blood cells and platelets, increasing the risk of blood clots, bleeding, and related complications. Timely diagnosis and careful management can help prevent complications and improve the quality of life for patients. Signs and symptoms Different patients will experience various signs and symptoms of polycythemia vera. Some people may remain asymptomatic for years, while others may experience significant discomfort in the initial stages. Headaches Frequent and severe headaches are a common indication of PV. This symptom occurs due to the increased thickness of blood. Higher viscosity makes it difficult for oxygen to travel to the brain. As a result, affected individuals often experience frequent and intense headaches. Dizziness Vertigo is another common symptom in patients with PV, which is characterized by frequent dizziness or a spinning sensation. These symptoms can significantly increase the risk of accidents and falls for the patient, particularly for older individuals who already struggle with balance issues. Persistent fatigue The body expends a substantial amount of energy in producing excessive cells, which leaves the patient with drained energy to carry out routine tasks.
