Furthermore, the early onset type 2 diabetes has distinctive clinical characteristics compared with diabetes in an older population. Specifically, the young people with type 2 diabetes has an even higher level of hemoglobin A1c and treatment with more insulin is frequently required at the time of initial diagnosis.

It is also reported that recovery time after the insulin treatment for patients who contracted diabetes before the age of 45 is slower than it is for patients who contracted diabetes after age 45
