What even is MASH? My doc mentioned it and I panicked — my results so far

NASH/MAFLD therapeutic landscape and liver and MASH: GLP-1 agonists are emerging as potential first-line NASH therapy.

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.

Dr.RaviCardio said:

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.

Liver imaging follow-up for liver and MASH: FibroScan at baseline showed CAP score 324 dB/m (moderate steatosis) and stiffness 8.8 kPa (possible fibrosis). Diagnosed with NAFLD.

After 10 months: CAP dropped to 237 dB/m (minimal steatosis) and stiffness normalized to 6 kPa. Hepatologist says the liver is essentially healing itself as the metabolic stress resolves.

GLP-1 agonists may become first-line NASH therapy. The Phase 3 data on semaglutide for NASH is very promising.

Coming at Dr.ObesityLA’s question from a different direction. Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.

Following on from mike.trainer_LA — and this may be the naive question:

How would you tell the difference between that and the alternative explanation?

Closing the loop on my own question.

Closing the loop. The answer turned out to depend on the detail I had left out of the opening post, which is a lesson about how to ask rather than about the subject.
