Diabetic ketoacidosis (DKA) is serious complication of diabetes mellitus that requires prompt recognition, diagnosis and treatment. It is characterized by a triad of uncontrolled hyperglycemia, metabolic acidosis, and increased total body ketone concentration. The overall DKA mortality rate recorded among children and adults is < 1%. For patients with DKA, appropriate administration of intravenous fluids and insulin with attention to associated fluid and electrolyte disorders can effectively and rapidly resolve metabolic dysregulation. Following acute management and restoration of physiological glucose levels, DKA requires identification of the precipitating cause to prevent recurrence of potentially life-threatening diabetic complications.

Obese individuals are less able to oxidize fat than non-obese individuals. Caloric reduction or fasting can detect ketonuria. We investigated the differences of metabolic parameters in the presence of ketonuria after a minimum 8 hr fast in a cross-sectional analysis of 16,523 Koreans (6,512 women and 10,011 men). The relationship between the presence of ketonuria of all subjects and prevalence of obesity, central obesity, metabolic syndrome, and obesity-related metabolic parameters were assessed. The ketonuria group had lower prevalence of obesity, central obesity, and metabolic syndrome than the non-ketonuria group. In addition, all metabolic parameters (including body weight, waist circumference, blood glucose, high-density lipoprotein, triglyceride, blood pressure, and insulin) were favorable in the ketonuria group than in the non-ketonuria group, even after adjustment for age, tobacco use, and alcohol consumption. The odds ratios of having obesity (odds ratio [OR]=1.427 in women, OR=1.582 in men, P<0.05), central obesity (OR=1.675 in women, OR=1.889 in men, P<0.05), and metabolic syndrome (OR=3.505 in women, OR=1.356 in men, P<0.05) were increased in the non-ketonuria group compared to the ketonuria group. The presence of ketonuria after at least an 8 hr fast may be indicative of metabolic superiority.
