This patient support community is for questions related to juvenile diabetes including celiac disease, depression, diabetic complications, hyperglycemia / diabetic keto-acidosis, hypoglycemia, islet cell transplantation, nutritional issues, parenting a diabetic child, pregnancy, pump therapy, school issues, and teens with diabetes.
Viruses are often involved. And trauma, like a car accident, can also bring it on. There are probably various other triggers too. Obesity is not a T1 risk factor as insulin resistance is typically not an issue. The onset of T1 does not appear to be related to dietary or lifestyle choices.

None of us are physicians, but volunteers who either have type 1 or as a parent or family member who are very involved with diabetes.
With type 1 the beta cells are destroyed in the pancreas due to the autoimmune response. I agree with Markie, it is usually triggered by something and many cases has a genetic factor that comes into play. Keep in mind there are also many cases that doctors cannot find a genetic reason. I personally believe from my own research that there is a combination of factors that come into play. Type 2 is very similar in treatment with diet, excercise and sometimes insulin and also manifests the same complications, but are very different in the presentation of what happens with the beta cells. Type 2 creates a resistance to how the body uses insulin where type 1's beta cells can no longer produce insulin.
Markie is also correct that we still do not know enough about how type 1 happens. Probably type 2 as well. We do know that obesity can diffently cause type 2, while you will find type 1's, upon diagnoses usually experience weight loss and is not associated with obesity in any way that I have ever heard of.
There have been recent studies that have created a gray area between the two regarding age and developing diabetes. It was generally thought that type 2 was always assumed to strike people who were older, well into adulthood. While I am sure more research needs to be done, I have heard reports with our children being less active because of our lifestyle and fast foods, obesity in children is rising and some as young as 13 are being diagnosed with type 2.
I hope this helps. If you have any other questions, please feel free to ask.
Best,
