GLP-1 receptor agonists (specifically semaglutide and liraglutide) improve liver histology in MASH patients, with semaglutide demonstrating the strongest evidence for resolving steatohepatitis without worsening fibrosis.

If you have MASH, GLP-1 medications like semaglutide are currently the most evidence-backed pharmacological option to improve liver health, potentially resolving the disease without worsening scarring. This is particularly relevant if you also have Type 2 Diabetes or obesity, as these drugs address the underlying metabolic drivers. While weight loss contributes, the histological benefits appear to extend beyond weight reduction alone.

GoodSupportsHIGH confidence
Among GLP-1RAs, semaglutide has the strongest evidence of liver histological benefit... In the liraglutide group, 9% of patients achieved resolution of NASH with liraglutide (vs. 9% with placebo, p = .019)... By week 72, 40%, 36% and 59% of patients achieved biopsy-confirmed NASH resolution without worsening of fibrosis in the semaglutide 0.1 mg, 0.2 mg and 0.4 mg groups, respectively (vs. 17% with placebo).

Why this rating

Based on multiple phase 2 RCTs (LEAN, Newsome et al.) and a proof-of-concept trial, though large-scale phase 3 definitive data is still ongoing.
