Alcohol-Related Liver Disease: Stages from Fatty Liver to Cirrhosis

Chronic heavy alcohol use damages the liver progressively. Early stages are often reversible with abstinence; advanced stages may be permanent.

Disease Spectrum

1. Alcoholic Fatty Liver (Steatosis)

Earliest stage. Fat accumulates in hepatocytes. Usually asymptomatic; reversible with abstinence.

2. Alcoholic Hepatitis

Inflammation and hepatocyte injury. Symptoms: jaundice, fatigue, abdominal pain, fever. Can be severe and life-threatening.

3. Fibrosis

Scar tissue replaces healthy tissue as the liver attempts repair. Architecture distorts, impairing function.

4. Cirrhosis

Advanced, irreversible scarring with nodular regeneration. Complications: portal hypertension, ascites, variceal bleeding, hepatic encephalopathy, liver failure.

5. Liver Failure

End-stage loss of synthetic, metabolic, and detoxification functions. Requires transplant evaluation.

Key Message

Abstinence is the single most effective intervention at any stage. Early detection via liver enzymes (AST/ALT), ultrasound, or elastography improves outcomes.
