Primary thrombocythemia which is also called essential thrombocythemia is a very rare blood clotting disease causing the bone marrow to produce large number of platelets.

Platelets enhance blood clotting and elevated platelets can result in blood clots that develop at a very fast pace.

What Causes Elevated Platelets

So, What Causes Elevated Platelets?

Let us have a look at what causes elevated platelets in a person:

Spleen Removal

Splenectomy or spleen removal can result in lifelong elevated platelets in people. Spleen helps in the removal of excess platelets from the bloodstream and if the spleen is not able to function in the proper manner, the result can be an extreme rise in the count of platelets.


Different types of infections can also result in elevated platelets. This generally happens due to cytokines- the hormones produced as part of the normal defense of the body against infections. Thrombocytosis caused due to infections tends to be very common among children in comparison adults.


Cancer can result in the damage of healthy body tissues which automatically results in increased loss of blood. The blood loss stimulates the bone marrow in making more blood cells leading to elevated platelet production.

Hemolytic Anemia and Iron Deficiency

People with hemolytic anemia and iron-deficiency might also suffer from Thrombocytosis. However, medical research in this field is being carried out in order to study and identify the association between anemia and Thrombocytosis.

Polycythemia Vera

This is very uncommon condition involving the increased production of platelets by the bone marrow. People suffering from this condition are at an increased risk of suffering from Thrombocytosis.
