Hyperglycemia hyperosmolar nonketotic coma (HHNC) is characterized by a very elevated glucose, typically above 600 mg/dL.When plasma glucose is above approximately 180 mg/dL, it begins to spill over in the urine, producing glucosuria.Given that glucose is osmotically active, it will pull an osmotic equivalent of water along with it, causing polyuria.Plasma osmolality is also found elevated above 300 mOsm/kg (the upper limit of normal) in HHNC because of the osmotic affect of the elevated plasma glucose.Blood pH and anion gap are typically normal in HHNC.Major factors distinguishing HHNC from diabetic ketoacidosis (DKA) and lactic acidosis include the pH and anion gap.In addition, glucose levels are typically not as elevated in DKA as in HHNC.
