Gamma-glutamyl transferase (GGT)
Stomach and gut healthGGT (Gamma-Glutamyl Transferase): An enzyme particularly sensitive to alcohol consumption and certain medications.
Elevated GGT can indicate bile duct issues, fatty liver disease, or alcohol-related liver damage.
Why this matters
Elevated GGT can indicate liver stress, bile flow issues, or the effects of alcohol and certain medications, often before symptoms appear. Lifestyle factors such as regular alcohol consumption, diet, and medication use influence GGT levels. Monitoring GGT over time helps track liver health and supports early lifestyle adjustments to reduce long-term liver risk.
How this connects to other biomarkers
- Elevated GGT with elevated Alkaline Phosphatase and Bilirubin, total is the classic pattern of cholestasis (slowed or blocked bile flow).
- Isolated GGT elevation often reflects alcohol use, certain medications (anticonvulsants, statins), or fatty liver disease.
- The GGT / HDL-C ratio combines liver stress and cardiovascular risk and rises with metabolic syndrome.
