Risk of ruptured spleen following a mononucleosis infection

Mononucleosis (mono) may cause an enlarged spleen, which could rupture if you are hit in the abdomen. A ruptured spleen is serious and requires immediate surgery to correct.

To reduce the risk of having a ruptured spleen, avoid heavy lifting or contact sports for 4 weeks after you become ill with mono or until your doctor says it is safe.
