What happens if white blood cells are high?
When you have a high white blood cell count, it is either a sign of infection and may be a sign that something is wrong in your bone marrow, as in leukemia. In leukemia, what happens is that you will have a very little percentage of mature white blood cells, and the constant influx of immature cells take away red blood cells, platelets, granulocytes, and lymphocytes as well, reducing the effectivity of the bone marrow to create new mature cells and leading to anemia, hemorrhagic manifestations, and immune problems. This overgrowth may also affect the liver, the spleen, and the lymph nodes.
