Ok here is fact on type 2.. it use ot be called Senile diabetes.
why,, because it came from old age and teh diseases and traetments that affected older people.

MODY is type 2 for juveniles. YES juveniles get type 2. Whiel you may think its because of lifestyle,, how ignormnat. Its just as genetic as you can be,And while they are finding an increase in insulinr eduction in many its still avery very real type of TRUE diabetes.
I come from 16 generations of diabetics. I wa fiorst dxd at 4! as MODY, then at & as n=borderline and then as I go tolder it was full blown diabetes.

Whiel I was lucky to be ocntrolled by quarterly shots of original beef insulin many were nto as fortunate. especially those with Brittle.

Whiel diet has a great affect on it, we have to look at all teh causes of it.
We have genetics, which play a very large part in when, how and which type we develop or get.
We have to look at teh clicnial factual studeis on disease that cause it. Measels, and mealseslinncoualtion, Virusus such as varicilla and other herpes which tax the immuni sytems to the max, we have Mono which n adults is a reason why so many develop it. We have cancer and the taxation on the sntire ysstem with Chemo, we have hep[atitis C which leads o not only to Epstein Barre but Gillian Barre, we have MS, PLeva, auto accidents, the Flu, a cold, an allergic reaction ot afood or medication, over use of corticosteroids, medications.

Why lifestyle may ahve an impact , type 2 is not lifestyle caused in all cases.
Type 2 is Dxd base don insulin levels and outcomes of the GTT.
