Hypoglycemia and pre-diabetes, right eye out of focus for more than 4 hours?

I am sorry to disagree with the other respondent but type 2 diabetes is not self inflicted. It has a complex genetic basis although it is true that life-style plays an important role in selected individuals. If you had an oral glucose tolerance test (I personally do not approve of the OGTT but it is recently increasing in popularity after decades of decline) and your glucose reached 196 mg/dL this would be consistent if not diagnostic of diabetes not a pre-diabetes. A non-diabetic at 2 hours after glucose loading should not exceed 140 mg/dL. I would however prefer a glycated (the more common term 'glycosylated' is biochemically incorrect) hemoglobin A1C prior to offering an official diagnosis. Periodic levels of 50 mg/dL do not necessarily reflect hypoglycemia as it is difficult to define a lower level of normal for blood glucose. It is not likely that what you ate triggered the change in vision as blurred vision is not typically seen unless the glucose is markedly elevated. Nonetheless you are a type 2 diabetic and you require education and treatment. The initial treatment is most often life-style modification rather than pharmacological intervention. If I may be of further istance please let me know. I wish you the very best of health and in all things may God bless. JR
