Diabetes is a disease in which blood glucose levels are above normal. Type<unk>  diabetes is usually diagnosed in children and young adults, and was previously known as juvenile diabetes. In type<unk>  diabetes, the body does not produce insulin. More specifically, the beta cells of the pancreas no longer make insulin because the body’s immune system has attacked and destroyed them. Insulin is a hormone that is needed to convert sugar (glucose), starches and other food into energy needed for daily life. The causes of type<unk>  diabetes appear to be much different than those for type 2 diabetes, though the exact mechanisms for developing both diseases are unknown. The appearance of type<unk>  diabetes is suspected to follow exposure to an "environmental trigger," such as an unidentified virus, stimulating an immune attack against the beta cells of the pancreas (that produce insulin) in some genetically predisposed people.
