Type-2 diabetes can be either insulin deficient (your pancreas doesn't produce enough of it), or insulin resistant (your cells can't process insulin efficiently). Both result in excessive glucose in your cells. Treatment is usually via diet and exercise, and in some cases, medication to assist your cells in processing insulin. Severe insulin deficiency sometimes requires insulin injections as part of the treatment regimen.
Type-1 diabetes is an auto-immune disorder, and congenital. Lifestyle isn't a factor. The body's immune system mistakes the area of the pancreas where insulin is produced (called the Islets of Langerhans) for foreign bodies and eventually destroys them. A relative handful of Type-1 diabetics may be able to temporarily avoid having to inject insulin with diet and exercise, but eventually virtually all Type-1 diabetics become insulin dependent.
