Why is Alt important?

ALT is an enzyme primarily found in liver cells and is considered the most specific marker of liver cell injury. In functional medicine, ALT elevation indicates hepatocyte damage and is often the first sign of liver dysfunction. Even mild elevations may suggest fatty liver disease, which is increasingly common due to poor diet and lifestyle factors. ALT is more liver-specific than AST, making it a sensitive indicator of liver health. Persistent elevation warrants investigation for causes including viral hepatitis, medication toxicity, autoimmune liver disease, and non-alcoholic fatty liver disease (NAFLD). Optimal ALT levels indicate healthy liver function and effective detoxification capacity.

What are the symptoms of abnormal Alt levels?

Mild ALT elevation is often asymptomatic. Higher levels may cause fatigue, abdominal pain, nausea, jaundice, and decreased appetite.
