What are “juvenile” and “adult” diabetes?
Abnormally high blood sugar defines both types of diabetes. Adult diabetes (Type 2 diabetes, non-insulin-dependent diabetes mellitus, or NIDDM), the more common form, is caused by a decline in tissue response to insulin. Juvenile diabetes (Type 1 diabetes, insulin-dependent diabetes mellitus, or IDDM), rarer but more severe, is caused by failure of islets to make sufficient insulin. The current recommended names are “type 1” and “type 2” diabetes.
