There is a mismatch between my meter readings and my A1c. During the winter I was eating pretty low carb c.20g daily but I had lots of health problems and sometimes had to take meds that can raise bg, so an A1c of 37 (down from a previous 41) seemed reasonable. I was confident that given better health I would improve on that. Over the next months I began taking Metformin and gradually worked up to 2g daily of Glucophage XR (recommended by Dr Bernstein as more effective than the generic Metformin) by the beginning of May. I was also even stricter about carbs. During the whole month of May there were only 2 days when my fasting bg was over 5, and those readings were only 5.2 and 5.3.
At the start of June I was devastated to find that my latest A1c had gone up to 38. Even allowing that A1c tests are not very accurate, that was at least no better than my previous A1c of 37. ( I would have expected at worst 34 = average 5.8). 38 = average 6.4. I am not troubled by the dawn phenomenon and it is very rare for me to see a meter reading at any time as high as 6. I try to avoid going as high as 5.6. So why this discrepancy? I am hoping soon to start testing with a Libre for a while, and maybe this will show something quite unexpected. Is something happening in the middle of the night, or a rise during the day that I am not catching, even though, because I suffer from gastroparesis (delayed stomach emptying) I often test repeatedly after meals, not just at 2 hours?
Any thoughts would be welcome.
