Type 2 diabetes remission can occur in people who have not had weight loss surgery, but it is very, very rare. Applying the results of this study to the entire 25.6 million Americans with type 2 diabetes suggests that 384,000 people could have some type of remission in the next 7 years. However, only 1,800 people would have a remission lasting at least 5 years.
So rare that it has not been a target for treatment. The standards of care has settled for less ambitious and "safer" approach that "treat to failure". That means the prevailing treatment protocol will treat a patient towards progressive failure and complications, increasing medical dosage as the condition deteriorate progressively over the years. This accelerated aging and progression to diabetes complication has tragically come to be accepted as inevitable...
Yet over the last few years, there has been increasing anecdotal evidence that for many, Type 2 diabetes is easily reversible and remission is an achievable and maintainable goal.
This simplified chart from Dr Ted Naiman illustrates why this may be so:-
