Symptoms

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

When to see a doctor

See your doctor promptly if you have pain in your left upper belly, especially if it's severe or the pain gets worse when you take a deep breath.
