Many ET patients are asymptomatic. Consequently, the disease is often diagnosed as part of a routine check-up, after a blood test reveals a high platelet count. When symptoms are present, they may include fatigue, or may be related to small or large vessel disturbance or bleeding.
Common ET Symptoms related to small vessel disturbances may include:
Headache
Vision disturbances or silent migraines
Dizziness or lightheadedness
Coldness or blueness of fingers or toes
Burning, redness, and pain in the hands and feet
When bleeding is present as a symptom of essential thrombocythemia, it can manifest as:
Easy bruising, nosebleeds or heavy periods
Gastrointestinal bleeding or blood in the urine
Thrombotic complications can also occur, resulting in:
Stroke
Transient ischemic attack (TIA)
Heart attack
Deep vein thrombosis or pulmonary emblous (blood clot in the lung)
Blood clotting in unusual locations, such as the abdominal veins
