Mild fat accumulation
Usually reversible with lifestyle modification

Grade 2

Moderate fatty infiltration
Higher metabolic risk

Grade 3

Severe fatty liver
Increased risk of fibrosis and cirrhosis

Possible Complications

Liver inflammation (Steatohepatitis)
Fibrosis
Liver cirrhosis
Liver failure
Increased cardiovascular risk
Diabetes progression
Rarely liver cancer
