There could be many things happening in the background...for a instance doctors should look other things not related to blood sugars, in my case found somebody who is testing everything on his hand to find from where is my problem coming...
A lot of doctors tend to forget that the endocrine system is not only one organ or two.... There are many factors to take in account in order to find the underline reason of such condition....
And remember that all sugars problems indicates a metabolic problem....not necessarily diabetes
