I am a 64 year old male have been diabetic type 2 for 12 years now, highest a1c has ever been is 6.2. The last couple years it has been 5.4 to 5.6 range and all I have ever taken is metformin hcl 500 mg twice a day. I have lost 60 pounds over the last few years by walking 3 and jogging 1 mile everyday , down to a relatively fit 208 pounds down from 270. I am 5ft 8 so still a little stocky. I eat what I want but its all in calorie intake and carbs ( I thought), not a lot of pasta lots of salad garden variety fruit blueberries apples and oranges, do have hamburgers and pizza in moderation. Iam not good at tracking my blood sugar thinking my a1c is in good shape (last one was 5.4 ) , well here is the question a bout once a month or so always mid morning i might feel a little out of it the all of a sudden I feel real crappy (lack of a better word) not realy light headed just crappy lol maybe a light sweat just dont feel like being around anybody. it does not last long 5 to 10 minutes or so sometimes a little longer I just keep on doing what I WAS at the time then I am fine. But it always happens around 10 or 11am, I have a bad habit of not eating anything in tell 1pm could that be it? the symptoms are like hypoglycemia but I didnt think that could happen if you were just on metformin. after I eat I do feel better. thoughts anybody I am worried about this and I thought I had my Diabetes under control thanks.
