10 Facts About Spleen Pain You Need to Know

5. Hypersplenism

In some cases, the spleen may perform its filtering job too well, removing blood cells too early. Hypersplenism is common and can occur anytime there is an issue with the spleen. If the spleen filters out too many red blood cells, anemia develops. Too few white blood cells in the body make it vulnerable to infection. Because the spleen also produces red platelets, disruption can reduce blood clotting capabilities. There may be few or no symptoms of hypersplenism, but a feeling of fullness or discomfort in the left chest area or upper left abdomen could indicate a problem. If the issue goes untreated, pain may set in.
