Type 2 Diabetes has a stigma attached to it. A common myth about diabetes, is that its mainly brought on by eating too much sugar and unhealthy foods, and by being overweight. Type 2 Diabetes, of course, is the type that develops over time because of many health factors, but being overweight doesn't actually have much to do with it. You can be thin and look otherwise "physically fit" and still get diabetes.
Myths like this are one of the reasons why November is National Diabetes Month, to raise awareness, educate people about the disease, and help diabetes patients properly manage it. It's important to stay educated about diseases like this, because they can happen to almost anyone who isn't closely caring for their health in certain ways.
