Like "Howdy Escp To have a Dr tell you have a "rare form of diabetes". and he gives you a med called gluemetza (which according to what i looked up is merely metformin hydrochloride extended-release tablets. I think that this Dr may be "shining you on", I would run (not walk) to another Dr and get a second opinion. A 5.6 A1c can happen after a period of high BG levels. My late wife had some high BG levels due to cortisone shots, but she had lows as well, She had days where she was over 300 mg/dl but she had some lows because of aggressive insulin therapy from her Endo. Her A1c for that period was 6.0. So it happens. I pray you get it straighened out! James "
