Hypersplenism

Hypersplenism is an overactive spleen. The spleen is an organ found in the upper left side of your abdomen. The spleen helps filter old and damaged cells from your bloodstream. If your spleen is overactive, it removes the blood cells too early and too quickly.

The spleen plays a key role in helping your body fight infections. Problems with the spleen can make you more likely to develop infections.

The spleen is an organ involved in the production and maintenance of red blood cells, the production of certain circulating white blood cells, as a part of the lymph system, and as a part of the immune system.
