Many of the early ideas about putting Type 2 diabetes into remission were generated from lifestyle intervention data. These studies essentially showed that weight loss and exercise could reverse diabetes in some patients. The problem was that many patients then re-presented later with a relapse of their condition, a point that highlights the concept of remission rather than cure.

Again the concept of remission has been reinforced as long-term data suggests that a reasonably large number of patients will eventually relapse with a representation of diabetes.
