I am 26 and have had type 1 since about 13. Over the past 3-4 years i have put on about 20 pounds with no explanation. I eat less and exercise just as much as I use to. My A1c has not been in control for a while now and my doctor has told me once I bring my A1C down to stable range that I should start to see the weight come off. I also recently started metformin. Has anyone experienced anything like this? I always thought diabetics tend to LOSE weight with higher sugar levels due to all the sugars spilling out. Now that I have been on the metformin, I have no appetite and regardless of the low-carb and now very scarce diet I am on, still not one pound will budge. I am worried I will never be able to lose anything; but right now I'm just concentrating on getting my A1c back down to a healthy range. Hopefully my doctor is right when he says the weight will eventually come off.
