Totally not dismissing the seriousness of Type 2 diabetes but Type 1 (also known as juvenile diabetes) is potentially more damaging to the body because you have it for LIFE. My mom has had her diabetes for about 40 years now, maybe more because I can't remember the exact age she was when she was diagnosed but she's 66 now. Type 2 diabetes can be reversed or very effectively controlled with weight loss, diet, and exercise and of course, medication. While I think anyone can get Type 2 diabetes, you drastically reduce your chances if you are not overweight and you exercise and eat a proper diet.
Famous people who have Type 1 diabetes or juvenile diabetes include Mary Tyler Moore, Nick Jonas, and Bret Michaels.
There's also a type of diabetes that happens during pregnancy but goes away.
Either type you have is a serious health risk though. :(
