Diabetes emergencies in the patient with type 2 diabetes

Type 2 diabetes has traditionally been associated with the development of hyperglycemic hyperosmolar nonketotic syndrome (HHNKS), yet evidence suggests that diabetic ketoacidosis (DKA) is increasing among this population. Patients with type 2 diabetes may develop DKA or HHNKS and require hospitalization. In addition, patients with type 2 diabetes, hospitalized for other medical or surgical conditions, are clearly at risk for the development of metabolic decompensation during hospitalization. This article explores the acute complications of type 2 diabetes and some of the issues associated with managing these patients in the hospital setting.
