Patch
Double diabetes probaby CAN be avoided, but not by some of those biddable folks who follow NHS advice on what to eat and how much medication to take. I have encountered a T2 diabetic now using a pump, whose insulin requirement is so high, he has to use U500, which is not produced in the UK and is imported from the USA. I wouldn't be surprised if some T1s end up in that state. My T1 husband has reduced his insulin requirement by about half since he cut back HARD on carbs. I suspect he'd be a double diabetic if he hadn't; always assuming he survived the kidney disease he has . Not everyone has knowledge needed to keep well or the motivation to acquire that knowledge.
I was told several years ago that my T2 would inevitably progress until I need insulin and woul probably keep on progressing. It hasn't happened yet. In fact my latest appointment with the nurse led to her saying, she'd barely find pre-diabetes in my blood tests [HbA1c 40mmol/l]
Had I believed the doctor all those years ago, where would I have been now?
Don't blame the patient. Just blame the medics who give no alternatives to "worst case scenarios" and set high BG targets
