It is a noninfectious disease. Among the body systems affected are the nerve, digestive, circulatory, endocrine and urinary systems.

The term "type 1 diabetes" has universally replaced several former terms, including childhood-onset diabetes, juvenile diabetes, and insulin-dependent diabetes mellitus (IDDM).

Various sources have defined "type 3 diabetes" as, among others, gestational diabetes,^[7] insulin-resistant type 1 diabetes (or "double diabetes"), type 2 diabetes which has progressed to require injected insulin, and latent autoimmune diabetes of adults (or LADA or "type 1.5" diabetes
