Hormonal

GLP-1 receptor agonists (specifically liraglutide and semaglutide) induce clinically significant, sustained body weight reduction in individuals with overweight or obesity, with histological resolution of NASH observed in approximately 40% to 60% of patients.

If you have obesity or type 2 diabetes, GLP-1 medications like semaglutide or liraglutide are highly effective for losing weight and improving liver health (NASH). They work by mimicking a gut hormone that reduces appetite and improves blood sugar control. While they require injections (or a daily pill for semaglutide) and may cause temporary stomach issues, the weight loss benefits are substantial and sustained when combined with lifestyle changes.

GoodSupportsHIGH confidence
The GLP- 1RAs, liraglutide and semaglutide, were associated with clinically relevant, sustained body weight reduction in individuals with overweight or obesity and without T2D... liraglutide and semaglutide led to histological resolution of NASH in ~40% to 60% of patients

Why this rating

Based on large phase II/III trials and meta-analyses, though fibrosis effects are not statistically significant.
