The human body requires the right balance of red blood cells, white blood cells, platelets, and plasma to survive. One way in which this balance can become disrupted is when there is an increase of white blood cells, a condition called leukocytosis.


1. Causes of Leukocytosis

Leukocytosis can be caused by a range of illnesses, most commonly an infectious or inflammatory disease. Cancers such as leukemia and certain lymphomas can also cause leukocytosis. Certain medications, such as steroids, can also lead to an increase in white blood cells. In some people, leukocytosis is the result of a spleen removal.
