Type 1 diabetes, previously referred to as insulin-dependent diabetes mellitus or juvenile-onset diabetes because of its earlier onset, is characterized by an abrupt and frequently complete decline in insulin production. Type 2 diabetes, formerly referred to as non–insulin-dependent diabetes mellitus or adult-onset diabetes, is marked by increasing insulin resistance and most commonly occurs in the overweight adult or adolescent; there is a strong genetic tendency toward the disease. Gestational diabetes can affect pregnant teens as well as the infants of diabetic mothers. There has been an increase in the prevalence of type 1 diabetes of 21% between 2001 and 2009 and an increase of 31% in type 2 diabetes in the same time period.1 While the cause of the increase in type 1 diabetes is unknown, some experts suggest that the increasing prevalence of type 2 diabetes may be a result of minority population growth, obesity, exposure to diabetes in utero, and perhaps endocrine-disrupting chemicals.1 Diabetes is the most common pediatric endocrine disorder, with an estimated prevalence of 1 in 400. As many as 34% of children with new-onset type 1 diabetes present in diabetic ketoacidosis (DKA).2 In children with known diabetes, DKA is much less common and tends to be clustered in a small subset of patients, with 5% of children with diabetes accounting for nearly 60% of DKA episodes.3 DKA is the leading cause of mortality in patients with diabetes <24 years of age, and cerebral edema is the leading cause of mortality in DKA.4
