I am a T2 doing very well on minidiab and metformin for 12 years. Then suddenly my bg shot up and I needed insulin shots - Lantus and Novorapid - with increased metformin, 500mg twice a day. I was alright with metformin for the past 2 years until now. During the past few days I have been getting sharp stomach and chest pains with a lot of gas. I also feel like throwing up every time after taking metformin. My stools are dark, which I suspect might be stomach bleeding. I've stopped the metformin for now and am taking antacids. I can't get to see my endo until next week. I know that T2 can't be on insulin alone as they need drugs to help the body cells counter insulin resistance. What type of questions should I be asking my endo? Thanks for any input.
