Also called Juvenile-onset Diabetes, IDDM (Insulin-Dependent Diabetes) and Type I, it is a deficiency condition wherein the pancreas does not manufacture enough insulin or what it makes is formed improperly. It is usually inherited, although it may not surface until pregnancy, recovering from a life-threatening illness, boot camp or some other profound metabolic stress. It can have a not-hereditary source, since it seems to enigmatically follow after a viral disorder, and can occur spontaneously as an auto-immune condition.
