Fact 4: The Lingering Shadow of Fatigue
If mononucleosis had a hallmark symptom, it would undoubtedly be fatigue. But this isn’t just the run-of-the-mill tiredness one feels after a hectic day. It’s a profound, often debilitating sense of exhaustion that doesn’t lift even after ample rest.
The big question is, why? Why does mono cause such severe fatigue? The answer lies in the body’s immune response. As the system battles the Epstein-Barr virus, it consumes a significant amount of energy, leaving the individual feeling constantly drained.
But that’s not the end of it. This fatigue doesn’t always leave when other symptoms do. It lingers, casting a shadow for weeks or even months. For some, daily chores become Herculean tasks. The need for rest becomes paramount, often affecting one’s work, studies, and overall quality of life. (4)
