I have read several places and not found the answer to this so can someone tell me if Metformin ER has been known to cause weight loss?
I have been taking Metformin for 5 years. Since I started taking it, I have lost 75 lbs that I was happy to see go. I have not lost any in the last year. So, in my opinion, yes you can lose weight on Metformin. I'm not sure about the metformin ER.
