Is it possible that I am pushing too far on my lowering my sugar level? as a type 2 diabetic. My first A1C after I was diagnosed as type 2 this year was 9. By eating better and walking, I have progressed to A1Cs of 5.5 then 5.4. My latest was 4.3. My doc is very pleased, but I am concerned that it maybe going too low. Several years ago I was classified as hypoglycemic. My concern is that now I seem to have more periods of light-headedness. I am also feeling less energic.

Congratulations on the excellent improvement of your diabetes control! The normal range for A1C is considered 4-6%, so your A1C is now in the normal range. If you are having episodes of lightheadedness, you should check your blood glucose level at the time you are experiencing it, as lightheadedness can be caused by a number of other conditions. Certain medications used to treat type 2 diabetes, especially insulin and sulfonylureas can cause hypoglycemia, but other medications such as metformin are not associated with hypoglycemia. Bring it up with your healthcare provider and ask whether any medications you are taking might be causing your symptoms
