What does mild abnormality in liver function mean?

Mildly abnormal liver function refers to situations where some key indicators in liver function tests, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin, exceed the normal reference ranges, but the deviations are relatively small and typically do not cause obvious clinical symptoms. This abnormality may be related to various factors, including viral hepatitis infection, unhealthy lifestyle habits (such as long-term alcohol consumption, high-fat diet, lack of exercise), and medication effects. Although mildly abnormal liver function does not require excessive concern, it should not be ignored either. It is recommended to seek timely medical evaluation for further investigation, identify the underlying cause, implement targeted treatment measures, and maintain healthy lifestyle habits to support liver health.
