An enlarged spleen is also known as splenomegaly.
Many conditions — including infections, liver disease and some cancers — can cause an enlarged spleen.
An enlarged spleen usually doesn't cause symptoms. It's often discovered during a routine physical exam.
Imaging and blood tests can help identify the cause of an enlarged spleen.
Treatment for an enlarged spleen depends on wha's causing it. Surgery to remove an enlarged spleen usually isn't needed, but sometimes it's recommended.
An enlarged spleen typically causes no signs or symptoms, but sometimes it causes:
- Pain or fullness in the left upper belly that can spread to the left shoulder
- A feeling of fullness without eating or after eating a small amount because the spleen is pressing on your stomach
- Low red blood cells (anemia)
- Frequent infections
- Bleeding easily
Contributing factors include:
- Viral infections
- Bacterial infections
- Parasitic infections
- Cirrhosis and other diseases affecting the liver
- Various types of hemolytic anemia
- Metabolic disorders
- Autoimmune conditions
