Hi - sorry for the delay in replying. I was initially diagnosed in my 30s as a Type 2 but I didn't have any of the usual signs and I already had one other autoimmune disorder (thyroid) and autoimmune disorders are very common in my family. Initially treated with Metformin (yuk) I went onto insulin (long acting and bolus) but categorised as a Type 2. After many years, really by happenstance I changed to a different diabetes clinic who did the now common tests for Type 1 and my categorisation changed. The main difference is that as a Type 1 (in my area at least) there has been much more support, particularly from a great DSN, access to a carb counting course and adequate test strips (I used to buy my own supplementary supplies). I'm now on Tresiba and Humalog. Not sure what the difference in the long run between an early diagnosed and a late diagnosed Type 1 might be but I guess everyone's journey to diagnosis is different and hence who knows how our bodies/metabolisms have coped (or not) along the way.
