I was diagnosed in 1997 with type 1 diabetes as I had the classic symptoms associated with it. My HBA1C has always been high, around 10 and all the professionals do not understand why my Sugars do not decrease. I weigh 10 stone height 6 foot 5. I am on levemir for meals and fiasp 24 and 20. My GP has questioned if I have diabetes as nothing is improving. I have the sensor now which helps me to monitor better. Sugars are stable between 5 and 9 until I eat during the day and dinner at 6pm always increases my sugars high, I change the insulin site regularly. So frustrated as nothing is working. I eat healthy and don’t eat cakes, biscuits. Any ideas? Thanks for your help!
