Many times a Type 2 Diabetic will be treated as a Type 1 (on the same medications etc) but will not actually BE a
Type 1. Reason being the treatments
for a
Type 1 are also effective on a
Type 2 if that severity of treatment is needed. It is believed that Type 2 can be prevented or delayed in its onset by proper diet and exercise just like you would do if you actually had Type 2. As far as I know there is no way to prevent Type 1.
