I have a family history of diabetes. Mother, grandfather & a borderline brother.I had gestational diabetes that went away after I lost the baby weight. I've eaten a very rigid healthy diet my whole life. Recently, I'm up all night in bathroom, my fingers are numb, my mouth tastes like sugar, I feel Whaley at times, my vision is blurry when I'm hungry and I feel at times like I'm dying of thirst. I've been testing my blood sugar and whenI eat 3 meals and snacks, I test up to 176 2 hrs after meals. It can be150, 135...all over map. My weight is low and my A1 was 5.2. I'm frustrated because in order to get a low BG reading,I just don't eat or eat very little. I can get my numbers under 100 this way. If I eat, it's much higher. The doctor doesn't believe I can eat diabetic. I'm seeing an endocrinologist on the11th. Should I request a glucose tolerance test? Maybe Im not diabetic, but my symptoms seem to lean that way.
