An enlarged spleen may cause:
- No symptoms in some cases
- Pain or fullness in the left upper abdomen that may spread to the left shoulder
- Feeling full without eating or after eating only a small amount — this can occur when an enlarged spleen presses on your stomach
- Frequent infections
- Easy bleeding
When to see a doctor
See your doctor promptly if you have pain in your left upper abdomen, especially if it's severe or the pain gets worse when you take a deep breath.
