What Is Kissing Disease?
6. Complications
One of the biggest causes for concern with mononucleosis is complications from an enlarged spleen. While it is not common, there is a risk of the organ rupturing. This causes a sharp pain in the upper left side of the abdomen, which comes on suddenly and requires immediate medical attention.
Mono can also lead to complications in the liver, causing jaundice and hepatitis. There are a few complications that are rare but possible, such as low platelet or red blood cell counts. Heart inflammation and nervous system complications may also occur.
