Fibrosis regression on GLP-1 — need advice

The liver data is among the strongest non-weight findings in the class.

NASH/MAFLD therapeutic landscape and liver and MASH: GLP-1 agonists are emerging as potential first-line NASH therapy. The Phase 2b data for semaglutide showed 59% NASH resolution (vs 17% placebo) with 43% achieving fibrosis improvement[1].

Mechanism: GLP-1R activation reduces hepatic lipogenesis, increases fatty acid oxidation, reduces hepatic inflammation, and may directly reduce hepatic stellate cell activation (fibrosis pathway).

With resmetirom (thyroid hormone receptor agonist) recently approved for NASH, the field is evolving rapidly. Combination approaches (GLP-1 + resmetirom) are being explored.

One thing that is still open after Dr.PainCLE’s answer:

Was that from a primary source or from a summary of one?

Liver ultrasound comparison for liver and MASH: my hepatologist ordered serial ultrasounds to track NAFLD regression.

Baseline: "Moderate hepatic steatosis, liver span 17.2cm, echogenic texture consistent with fat infiltration"
Month 8: "Mild steatosis, liver span 15.8cm, improved echogenicity"
Month 14: "Minimal to no steatosis, normal liver span 14.5cm, normal echotexture"

My liver literally shrank and de-fattened. The ultrasound tech said she's seen this pattern increasingly in GLP-1 patients and it's remarkable how consistently the fatty liver resolves.

Closing the loop on my own question.

Update: the thing I was blaming turned out not to be the cause. Leaving the original post as written rather than editing it, so the mistake stays visible for whoever searches this next.

True, and it depends on a baseline nobody has stated. Without knowing where someone started, the same number can be an excellent result or a disappointing one.
