Pretty dangerous, right? I checked the blood work record 10 ys ago. Y2009, Found that my fasting blood sugar is 6.0 mmol, which can be diagnosed as pre diabetes, yet in Asian standard, it's still normal for their reference number is under 6.1 mmol In Canadian ER, Random blood sugar 8.5mmol, 9.5mmol, 12.5 mmol, 7.0 mmmol, 7.9 mmmol, 7.8 mmol, undiagnosed again. Fasting blood sugar 5.8mmol once, others are all under 5.6mmol, undiagnosed again. I used to have protein in urine, slightly blurry vision, unhealed injury for years, but never think if it's diabetes, for I have hypothyroidism and autoimmune disorder as well. BTW, my lipid is bad, high cholesterol, high triglycerides, high LDL.family doctors don't link it with possible diabetes. My fasting insulin is higher than the normal range, 176mmol, 205 mmol, 2 hours after meal was 295 mmol. 5 to 190mmol is the normal range. Apprently hyperinsulinmia. Plus, I also have about 4 years of fatty liver. Now it's 2018, last time fasting blood sugar 6.5 mmol, finally showed impaired glucose fasting in the report . According to Canadian standard reference. However, my Ha1c is always at 5.1-5.6. Canadian doctors refused to diagnose as prediabetes. As those numbers are pretty bad.
