Between my last Hb1Ac of 64 and when I was actually diagnosed last December there was a period of between 12 or 18 months not quite sure of the exact amount of time. But in that time I was not self testing and was not being tested by doctor so I have no idea what my blood sugars levels where in that intervening time. If I had had the sense and confidence to purchase a meter and self test in that time I may have been able to save myself a lot of trouble and maybe prevented some of the complications I now have. I can now only guess at what the levels may have been though I have noticed as I do check my blood oxygen levels regularly and have done so for a long time that when blood sugars are high blood oxygen levels are low and I do recall in that intervening time I had some very low blood oxygen levels well down into the low mid 80%s so I think my BG levels must have been very high during that period. So all I can say if any one thinks or suspects that they may be diabetic get a meter and check and don't take any **** from so called medical experts. Because it's your life not theirs.
