An enlarged spleen (splenomegaly) is when the spleen is larger than normal. The spleen is an organ that is located in the upper left area of the abdomen, just under the ribs. The spleen is like a storage unit for red blood cells, and it also works to filter and clean the blood. It destroys cells that are damaged or worn out. The spleen is also important for fighting disease.
This condition is usually noticed when the spleen is almost twice its normal size. An enlarged spleen is usually a sign of another health problem.
In some cases, there are no symptoms.
If these treatments do not help or if the cause cannot be found, surgery to remove the spleen (splenectomy) may be recommended. After surgery, you may need to have vaccinations or take antibiotics to prevent infections.
