I am on metformin and a low carb diet. i do a 6 month blood test for my sugar. i feel horrible today. so i tested my sugar it was 270. what should?

See doctor soon : If you are not aware of it, you clearly have diabetes and despite the metformin and low carb diet , it is not controlled at all . Please see your doctor soon to get your medication regimen intensified . If you are indeed feeling horrible, go to an urgent care or er now, as a complicated condition called diabetic ketoacidosis can be life threatening . Good luck
