Diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS, also known as hyperosmotic hyperglycemic nonketotic state [HHNK]) are two of the most serious acute complications of diabetes. They are part of the spectrum of hyperglycemia and each represents an extreme in the spectrum.
The treatment of DKA and HHS in adults will be reviewed here. The epidemiology, pathogenesis, clinical features, evaluation, and diagnosis of these disorders are discussed separately. DKA in children is also reviewed separately.
