I don't understand Metformin much

So I am pre diabetic. My a1c was 6.2
I am on 500mg daily.
I understand metformin makes the liver produce less sugar, the gi tract absorbs more sugar to eventually excret out, and makes you less insulin sensitive.
What I don't get is how it does not manage the blood sugars.
If that is the case how can it lower the a1c?
If you eat less carbs and if some of those carbs while low still affect the blood sugars then how does metformin help?

  1. Hi . You are far from alone. Many of the best scientists and doctors don't reeally understand how metformin works. Here is a 2022 article from Yale School of Medicine that you might find interesting: https://medicine.yale.edu/news-article/how-a-widely-used-diabetes-medication-actually-works/. I hope this helps and that someone with a better understanding jumps in here as well. Best wishes. - Lori (Team Member)

    1. I am not sure. The numbers seem good after meals except a couple of times like 190 within one hour. Same pattern as before metformin. I should know more once I get my a1c checked in a few weeks.

    2. If you don't mind updating us after your next A1C test, that would be great. It will be interesting to see how much metformin helped. - Lori (Team Member)
