Clinical signs and symptoms and laboratory picture of NAFLD.

Frequently asymptomatic	High ALT (2–4x)
Vague and unspecific symptoms	High GGT (2–6x)
Abdominal right upper quadrant discomfort	Mild elevation of AST (can be elevated in cirrhosis)
Fatigue
Dyspepsia
Overweight (BMI ≥ 25 kg/m2)	Blood glucose > 100 mg/dL
High blood pressure	Triglycerides > 150 mg/dL
Central adiposity	Total cholesterol > 200 mg/dL
Hepatomegaly (in 50%)	LDL > 130 mg/dL
Splenomegaly (in 25%)	HDL < 45 mg/dL

NAFLD: nonalcoholic fatty liver disease; BMI: body mass index; ALT: alanine aminotransferase; GGT: gamma-glutamyl transferase; AST: aspartate aminotransferase; LDL: low density lipoproteins; HDL: high density lipoprotein.
