Diabetes, obesity and metabolic risk.

Who to screen

• Type 2 diabetes or prediabetes

• Obesity with one or more cardiometabolic risk factors

• Persistently elevated liver enzymes

• Hepatic steatosis on imaging

Pathway

• FIB-4 below 1.3: low risk; repeat in 1 to 3 years

• FIB-4 1.3 or higher: vibration-controlled transient elastography (or ELF test)

• Liver stiffness above about 8 kPa, or FIB-4 above 2.67: hepatology referral

Treatment

Target 7% to 10% weight loss or more. Consider resmetirom or semaglutide for MASH with F2 to F3 fibrosis. Manage cardiovascular risk aggressively.
