What is hyperglycemic hyperosmolar nonketotic syndrome (HHNS)?

Hyperglycemic hyperosmolar nonketotic syndrome (HHNS) develops more slowly (over days to weeks) than diabetes-related ketoacidosis. It occurs in patients with Type 2 diabetes, especially the elderly and usually occurs when patients are ill or stressed. If you have HHNS, you blood glucose level is typically greater than 600 mg/dL. Symptoms include frequent urination, drowsiness, lack of energy and dehydration. HHNS is not associated with ketones in the blood. It can cause coma or death. You’ll need to be treated in the hospital.
