Interesting. Hadn't heard of this, but it kind of makes sense since metformin increases insulin sensitivity -> could potentially decrease the amount of insulin someone needs. Or make them more responsive to the amount given, which would have long term benefits related to decreased usage.
Will have to read more into this.
But as far as your theory that it's because drug reps don't push it because it's cheap, that may not be the case. As far as I know the newer SGLT2 inhibitors that help you pee out sugar are rather expensive. That could hypothetically work in type ones as well, mechanistically. I think it's more likely to do with what local institution did the research and if it hasn't made it across the pond yet.
It makes sense for type 2 diabetics who have insulin sensitivity issues, but doesn't make a lot of sense in true T1DM given that their issue is not sensitivity, but insulin production. The REMOVAL trial actually set out to answer this question and found that there is no evidence of improved glycemic control or a reduction in insulin used when metformin was added to the typical insulin regimen of T1 diabetics. The study does use a bizarre primary endpoint; however, the results match our current understanding of T1 diabetic pathophysiology.

The way it's been promoted to us is that it stops the liver from dumping glucose.
For this reason you also see T1 taking a shot of vodka before working out, this accomplishes the same thing as metformin, on a macro level. (But is not so healthy)
We played with ozempic briefly. The SI factor in her pump dropped (number raised) by 20% or more. That was before she couldn't hold any food down.
