Patients with essential thrombocythemia may have no signs or symptoms.

Essential thrombocythemia often does not cause early signs or symptoms. It may be found during a routine blood test. Signs and symptoms may be caused by essential thrombocytopenia or by other conditions. Check with your doctor if you have any of the following:

  • Headache.
  • Burning or tingling in the hands or feet.
  • Redness and warmth of the hands or feet.
  • Vision or hearing problems.

Platelets are sticky. When there are too many platelets, they may clump together and make it hard for the blood to flow. Clots may form in blood vessels and there may also be increased bleeding. These can cause serious health problems such as stroke or heart attack.

Certain factors affect prognosis (chance of recovery) and treatment options for essential thrombocythemia.

Prognosis (chance of recovery) and treatment options depend on the following:

  • The age of the patient.
  • Whether the patient has signs or symptoms or other problems related to essential thrombocythemia.
