I like your motivation. You remind me of 3rd year med students full of idealism ready to change the world. Meanwhile, I just admitted 3 patients for dka that were only on metformin just this week. They're always new diagnosed diabetics with A1c 10+ that refuse to start insulin because they think they can fix themselves with life changes
Metformin makes your body more sensitive to the insulin it already produces to lower blood sugar. Yes it's a temporizing measure like all medicine, but it takes tremendous willpower to resist excess carbohydrates or calories for that matter.
They can tell you to work out and eat right just the same, but they ultimately have no control on patient compliance. Insulin and metformin are prescribed to keep diabetics from going DKA or developing acute organ failure and then hospitalized which is exponentially more expensive to treat. When patients don't eat right nor take insulin or any prescribed meds for that matter, chalk that up to personal responsibility and Darwinism.
Hospitalist here, what's interesting is that covid seems to have wiped out all other viruses let alone flu e.g. other run of the mill cold viruses. There weren't vaccines for those, but now we have this. Regardless of how you feel about this new vaccine, it'll be interesting to see how the next flu season turns out.
