Wow. You are so ignorant it's not even funny. Why are you posting this is in the TYPE 1 diabetes forum?
Autoimmune Type 1 diabetes is an autoimmune disease. It is NOT caused or related to obesity, poor diet, sugar, or lack of exercise. It HAS been linked to certain viruses.
Ignorant people like you are the one kind of person mothers of children with Type 1 diabetes hate the most.
