Can elevated platelet count cause dizziness and headache?

Elevated platelets may cause dizziness and headache. Thrombocytosis may lead to an increase in blood viscosity, affecting blood supply to the brain and causing symptoms such as dizziness and headache. When the platelet count is high, the blood flow rate slows down, and insufficient blood supply to the brain may lead to dizziness and headache. This condition is common in primary thrombocytosis or secondary to infections, iron deficiency anemia, and other diseases. Patients may experience symptoms such as fatigue, blurred vision, or numbness in their hands and feet. Mild elevated platelets can be improved by drinking plenty of water and moderate exercise to improve blood circulation. If the symptoms persist or worsen, seek medical attention promptly to investigate the cause. In rare cases, a significant increase in platelets may lead to thrombosis, causing more serious cerebrovascular problems. These patients may present danger signals such as severe headaches, vomiting, or consciousness disorders and require immediate medical attention. Some bone marrow proliferative diseases such as polycythemia vera may also lead to abnormal platelet elevation, requiring a hematologist to perform bone marrow puncture and other examinations for diagnosis.

It is recommended that patients with high platelet count maintain sufficient water intake, avoid prolonged sitting, and regularly monitor platelet count. When persistent dizziness and headache occur, blood routine should be checked, and if necessary, further tests such as coagulation function and bone marrow puncture should be performed. Adding foods rich in unsaturated fatty acids such as deep-sea fish and nuts in moderation to the diet can help improve blood flow.
