Splenectomy - Topic Overview

Splenectomy is surgery to remove the spleen. The spleen gets rid of old and damaged red blood cells. Red blood cells may be damaged by a health condition, such as thalassemia or sickle cell disease. When the blood cells pass through the spleen, they are often destroyed. This can leave the body with too few red blood cells.

Some people have their spleen removed to keep from losing too many red blood cells. Other people may need to have it removed if the spleen is injured in a car accident or by another trauma.

  • Antibiotics. Many people who have their spleen removed take antibiotics for a while. They also may need to take antibiotics whenever they have a fever, which could be a sign of a serious bacterial infection. Talk to your doctor about what to do if you have a fever.
