For clarification Hypoglycemia is Type 1 Diabetes. This forum is for T2's, Hyperglycemia.
"Could something other than dietary habits be causing this fluctuation in my blood sugar?"
Issues with your thyroid misfiring. Get a TSH test. Losing weight even a few pounds have been shown to improve blood glucose levels. In the diabetes world being 25 lbs overweight is borderline obesity.
hypoglycemia is not diabetes. That just gives the doctors more confusion and they are confused enough. I have had low blood sugar with the gtt but know I had the symptoms when I was young. I have yet to find a doc who knows more than any layman who has to cope with it. Most of them do not understand the term even.
Anybody knows a good doctor in Falls Church or Wash DC area please tell me. I would also be glad to go to NIH in Bethesda.
Thanks
