NAFLD / MASLD
Risk Calculator.

Fatty Liver Index (FLI): evidence-based, non-invasive screening for hepatic steatosis (fatty liver disease) validated in the Indian population. Requires only a basic lipid panel.

📌 WHO Asian: ♂ <90 cm low · ≥90 elevated  |  ♀ <80 cm low · ≥80 elevated (INASL 2022)
Normal <150 mg/dL · High ≥200 mg/dL
Gamma-Glutamyl Transferase · Normal ♂ <65 · ♀ <35 U/L
MASLD Criteria & Risk Factors optional, for complete screening

MASLD requires hepatic steatosis + ≥1 of 5 cardiometabolic criteria (AASLD/EASL 2023). HDL-C is criterion 5:

Low HDL: ♂ <40 · ♀ <50 mg/dL = MASLD criterion 5

INDIAN CONTEXT

38.6% prevalenceIndia has among the world's highest NAFLD rates (INASL 2022)
Lean NAFLD16–25% of Indian NAFLD patients have BMI <23: thin-fat phenotype
Asian BMI cutoffs≥23 overweight · ≥25 obese (vs WHO 25/30)
Fibroscan next stepCAP via Fibroscan = INASL gold-standard follow-up

⚕️ Disclaimer: FLI is a validated non-invasive screening tool for hepatic steatosis, not a diagnostic test. Liver biopsy remains the gold standard (INASL 2022). FLI ≥60 indicates high probability of fatty liver and requires clinical confirmation via USG abdomen, Fibroscan, or specialist evaluation. Not applicable during acute illness, pregnancy, or lactation. Adults 18–85 only. Does not replace clinical judgment or specialist consultation. Consult a qualified hepatologist, gastroenterologist, or registered clinical dietitian for medical decisions.
