Nothing is carved in stone and I was not trying to make a medical diagnosis. What Leads to Diabetes?
Type 1 and type 2 diabetes have different causes. Yet two factors are important in both. You inherit a predisposition to the disease then something in your environment triggers it.
Genes alone are not enough. One proof of this is identical twins. Identical twins have identical genes. Yet when one twin has type 1 diabetes, the other gets the disease at most only half the time.
When one twin has type 2 diabetes, the other's risk is at most 3 in 4.
