The clinical symptoms of viral hepatitis are mainly related to liver function. Generally, there are no obvious symptoms when liver function is normal or mildly abnormal. However, when liver function becomes significantly abnormal, symptoms such as fatigue, aversion to oil, nausea, abdominal distension, and poor appetite may occur. Different types of viral hepatitis have different prognoses and severity of illness. Treatment should be tailored to the actual situation, including liver protection, enzyme reduction, and addressing the cause through comprehensive treatment.
