That stereotype definitely exists, in the past it is an impression I have even felt from the
@DiabetesUK Twitter account, though I cannot think of any examples at the moment.
But in professional contexts in general, there is a constantly linking of type 1 diabetes with something that happens to people through no fault of their own, whilst type 2 as often linked with obesity. So even without the suggestion of fault or blame, it exists. Both by contrast with the way type 1 is differently portrayed in this regard, but also that the obesity connection focuses on poor diet and not it being a genetic thing that affects some people through no fault of their own.
Whilst it may be totally unconscious and unintended, but no active effort is made to avoid this and consider those who are not obese.
But I feel it also exists within healthcare. I was diagnosed with type 2 diabetes but was not obese, so was immediately put onto Metformin and Gliclazide and given a glucometer. I then attended a DESMOND course. However the only good helpful about it for me was being constantly told how thin I was. Because I was not thin so that felt good, eve if it was only relatively.
The entire focus on the course was on diet to lose weight, though. Meanwhile my biggest issue was that I now was at risk of hypos so help understanding and dealing with them would have been useful. This was not covered at all, which was understandable when it affected no one else on my course dates. So it was something I had to work out and understand for myself.
Because I was prescribed a glucometer and told to test twice a day I did not even know that I was supposed to test whenever I felt one. I did not want to use up my prescription. I also struggled to understand why they were happening whenever they did, which caused anxiety and upset until I reached the point of accepting they cannot be explained. I have never tested after treating a hypo, I never knew you were suppose to do that until recently.
Even aside from the stigma of how the two types of diabetes are discussed, even the support for type two diabetes seems aimed at people who are obese. Again it may be unconscious and unintended, but again with no active effort made for those who are not obese.
