Essential Thrombocythemia (ET)?

Essential thrombocythaemia (ET) is a rare blood disorder that causes your body to produce too many platelets. Platelets are blood cells that help your blood clot and stop bleeding. Too many platelets can increase your risk of blood clots in your arteries or veins, leading to severe complications such as stroke, heart attack, or pulmonary embolism.

​

ET is estimated to affect about 30 people per million in the general population. It can occur at any age but is more common in older adults. The average age of diagnosis is around 60 years. ET affects slightly more women than men.
