Yes.
Essential thrombocythemia is a condition characterized by an increased number of platelets (thrombocythemia). Platelets (thrombocytes) are blood cell fragments involved in blood clotting. While some people with this condition have no symptoms, others develop problems associated with the excess platelets. Primary thrombocytosis, also known as essential thrombocythemia (or ET) , is a disease in which abnormal cells in the bone marrow cause an increase in platelets. The cause is unknown. Secondary thrombocytosis is caused by another condition the patient may be suffering from, such as: 1  anemia due to iron deficiency. 2  cancer. Essential thrombocythemia is an uncommon disorder in which your body produces too many blood platelets. This condition may cause you to feel fatigued, lightheaded and to experience headaches and vision changes. It also increases your risk of blood clots. Essential Thrombocythemia. Essential thrombocythemia (ET) Is one of a related group of blood cancers known as “myeloproliferative neoplasms” (MPNs) in which cells in the bone marrow that produce the blood cells develop and function abnormally. Essential thrombocythemia is a disease in which too many platelets are made in the bone marrow. Essential thrombocythemia causes an abnormal increase in the number of platelets made in the blood and Essential Thrombocythemia. Essential thrombocythemia (ET) is a type of blood cancer known as a myeloproliferative neoplasm. It involves the abnormal development and function of bone marrow cells that produce blood cells, and leads to the overproduction of blood cells known as platelets. Abnormal blood clotting (thrombosis) is common in people with essential thrombocythemia and causes many signs and symptoms of this condition. Clots that block blood flow to the brain can cause strokes or temporary stroke-like episodes known as transient ischemic attacks. Thrombocytosis and thrombocythemia are conditions in which your blood has a high number of platelets, also called thrombocytes, because a clot is also called a thrombus. When another disease or condition causes a high platelet count, the term thrombocytosis is preferred, or secondary or reactive thrombocytosis. Essential Thrombocytosis. Essential thrombocytosis (ET), or primary thrombocythemia, is a rare disorder in which the body produces too many platelets for unknown reasons. This can cause abnormal blood clotting or bleeding.
