Shruti I was on metformin from January of this year until this week. I lost 3 stone and look skeletal. Dr took me off it for that reason on Monday and put me on Gliclazide...horrible with hypos that scared the life out of me. I've now stopped taking it as from today. I was diagnosed prediabetic in December of last year. Gliclazide shouldnt be given to Non diabetics hence the awful hypos. I found out that information myself as I was so scared. I'm now going to try to reverse the prediabetis with exercise and high calorie/low carb food. I know it can't be cured as such but I can try to stop it getting any worse. My fasting nos are usually 4.3. My a1c test in July said 45%..prediabetic. Before Metformin it was 46% so still not quite diabetic t2. I would have stayed on Metformin if it wasn't for the weight loss as I felt fine on it. It may be worth letting your dr know about the weight loss. Some drs dont believe Metformin can do this to us. I hope it all gets sorted out for you.
