Definition
Hypersplenism is a condition in which the spleen is overactive. It can be caused by tumors, anemia, malaria, tuberculosis, and various connective tissue and inflammatory diseases.
Symptoms include an enlarged spleen that is often accompanied by a low level of one or more types of blood cells. The enlarged spleen can cause stomach pain on the left side, as well as a premature feeling of fullness after eating.
