Reading another thread where there were the usual discussions of reversal/remission/control I realised that I don't know what it means to transition from pre-diabetic to diabetic. It is mostly accepted that, once you are diabetic you are always diabetic, you can control your BG to normal levels but you are not cured. I believe the implication of the term pre-diabetic is that if you take action at this point (which not many people do) you may not become diabetic. Is this cured, or no different from someone who was diabetic but is now controlled? Is there something that happens that results in a cliff edge transition to diabetic, maybe if you have lost function in 50% of your beta cells it is too late but 49% you can recover from? Does anybody know?
