GGT as a liver health marker — 6 month update

Dr.ObesityLA said:

Liver enzyme update related to liver and MASH: I had mildly elevated ALT/AST at baseline (likely NAFLD).

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.

ALT was mildly raised at baseline, normalised at month five, and I now have no idea whether anything happened to the fibrosis that actually matters.

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.

Coming at Dr.MetabolicMD’s question from a different direction. There is a difference between no evidence and evidence of no effect, and this subject is one where the two get swapped freely in both directions.

Happy to go further on any of that.

Following on from jim_asheville — and this may be the naive question:

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

OP back with an update, since a thread like this is useless without one.

Late follow-up. I did not do what was suggested, I did something adjacent, and it worked; posting the difference in case it matters to somebody.
