Type 1 diagnosed after having children in my late 30s. For 3 years my A1C was 13 even though I constantly checked my blood and followed endocrinologists directions on insulin dosing-finally dr realized it wasn't user error and tested for celiac which I addressed thru diet and now my A1C is stuck at 9 and my endo thinks it is again user error but I follow what should be an effective regiment- I have highs and lows often for a few months then steady for a few months over and over. Other than things like stress and exercise (which stay constant) has anyone had an experience like this and have any suggestions for what I might look at, try? Could it be another food allergy? My dr is not going to play detective with me- it is always going to be user error so this is my last shot before giving up on my goal of 7. Thank you
