2 doctors agree
In brief: Why you need insulin
Dm1 results because body can't make insulin, possibly due to a viral infections destroying the insulin-producing cells of pancreas, thus Insulin must be given.
Little genetic compoment. Dm2 has a high genetic component and is related to Insulin resistance. Fat make body more resistant and the pancreas "tires out" trying to compensate. Diet, exercise, meds, later Insulin usually treat.

Agreed. One more point to add, Insulin may be needed for some type 2 diabetics, even if their pancreas is still working.

Type 1 is insulin deficiency and type 2 is insulin resistance
