Not doctor just a person with common sense, but seems Metformin when first came out passed was for cholera?.....
What I cannot understand why would one want to take Metformin or other which only pushes the sugars here and there in the body, it does not make you actually better? infact, next A1C test, it may show lower and sugars, but the question one has to ask oneself is...that the Docs don't explain, is my test correct or false indications, as if medications are taken, the test shows better results, in reality the problem is still there, and even worse, surely its only common sense, ditch the medications, I did anyway, and simply change your lifestyle, exercise more, eat low carb and keto style eating plan, fabulous and wonderful foods, works for me, lost 20 kilos in 11 months, eating butter, cheese, cream, yes really and 30g carbs a day, but not carbs of potatoes, pasta, bread or rice, carbs such as veggies and other. Walking approx. 8 klm a day.
So, what happened, next A1C I was down 23% in 4 months, the good news is I know that the results are correct, why, my body my own body adjusted the sugars to lower and my A1C by its own with change of diet and lifestyle, so compare the two, take a drug, your tests may be lower, but its false, compared to a lower A1C which has taken place by natural way.......
Hope this help
