What Is Mononucleosis?
4. Ruptured Spleen
As mentioned, mono can cause the patient’s spleen to become enlarged. This is because the spleen is a part of the immune system and, in cases of mono, it will be working harder than usual to help filter the virus from the blood. While a swollen spleen in itself is not a medical emergency, it can lead to something far more severe.
Mononucleosis will sometimes result in the spleen becoming ruptured. This is a very dangerous condition and should be treated as an immediate medical emergency. Symptoms of a ruptured spleen include severe pain in the abdomen area, as well as confusion, blurred vision, light-headedness, and shock.
