What is swollen spleen?

A swollen spleen is an abnormally enlarged spleen. The spleen is an organ located in your abdomen on the left side.

The medical term for a swollen spleen is splenomegaly. Common signs of a swollen spleen are hiccups, a loss of appetite, and pain in your abdomen on the upper left side. In some cases, there may be no symptoms of a swollen spleen.

There are many causes of a swollen spleen. A swollen spleen may be caused by viral, parasitic, or bacterial infections, such as mononucleosis.
