I was diagnosed a couple of months ago. My BG and HbA1c levels were really high but since I've been on Metformin and Gliclozide the BS has come done. How long does it usually take for HbA1c levels to come down to normal (I tested at 138!) and can it impact the keto diet? ie I'm doing Keto and taking lots of exercise but not losing weight? Your experience and advise most welcome.
