10 Hepatitis A Symptoms
Symptom #2: Fatigue
Fatigue is a complex symptom that is often overlooked by physicians because of the difficulties in defining and treating it. Fatigue encompasses a range of complaints including malaise, lethargy, lassitude, and exhaustion. Acute presentations of HAV infection are associated with fatigue, which gradually subsides when the patient recovers clinically.
It is important to differentiate central fatigue from peripheral fatigue. Peripheral fatigue manifests clinically as a weakness because it implies a neuromuscular dysfunction and occurs when muscles are over-utilized. Conversely, central fatigue is characterized by difficulty in performing physical and/or mental activities and is associated with a higher perceived effort when performing tasks. Thus, it arises within the central nervous system.
