Nucleos(t)ide Analogue Antiviral Therapy
Oral antivirals such as entecavir or tenofovir suppress viral replication, reduce liver inflammation, and decrease progression to cirrhosis. Typically reserved for severe acute cases or those progressing toward chronic infection.
Additional treatment options
Alcohol Cessation and Liver Protection
Eliminating alcohol consumption prevents synergistic liver damage when combined with viral hepatitis. Avoiding smoking and environmental toxins further protects hepatic function during recovery.
lifestyleHepatic-Friendly Nutritional Support
Emphasizing whole foods, adequate protein, and avoiding processed foods reduces liver workload. Limiting sodium helps prevent fluid retention if liver function becomes impaired.
dietarySupportive Care and Symptom Management
