Why GLP-1 medications for NAFLD / MASLD (Fatty Liver Disease)
Wegovy (semaglutide 2.4 mg) was FDA-approved in August 2025 for MASH with moderate-to-advanced (F2–F3) liver fibrosis — the first GLP-1 approved for a liver disease — based on the phase 3 ESSENCE trial (MASH resolution and fibrosis-improvement endpoints met). Resmetirom (Rezdiffra) was the first MASH-specific drug (approved 2024). Tirzepatide showed similar liver-fat and fibrosis improvements in SYNERGY-NASH but is not yet FDA-approved for MASH. Evidence grade: A (phase 3 RCT for semaglutide). Outside the Wegovy MASH indication, GLP-1s are used off-label or based on coexisting obesity/T2D indications.
