Hyperosmolar hyperglycemic state (HHS), also known as hyperosmolar non-ketotic state (HONK), is a complication of diabetes mellitus in which high blood sugar results in high osmolarity without significant ketoacidosis. [4] [5] Symptoms include signs of dehydration, weakness, leg cramps, vision problems, and an altered level of consciousness. [2]
Hyperosmolar syndrome or diabetic hyperosmolar syndrome is a medical emergency caused by a very high blood glucose level. The prefix " hyper- " means high, and " osmolarity " is a measure of the concentration of active particles in a solution , so the name of the syndrome simply refers to the high concentration of glucose in the blood .
A concentration of an osmatically active substance is said to be hyperosmolar if a high concentration causes a change in osmatic pressure in a tissue, organ, or system. Similarly, it is said to be hypoossmolar if the osmolarity, or osmatic concentration, is too low.
hyperosmolar non-ketotic state (HONK) or Hyperglycemia hyperosmolar state (HHS) is an acute complication sharing many symptoms with DKA, but an entirely different origin and different treatment. [15] Oppositely, the prevalence of HHS is common in individuals with T2D.
Hyperosmolar hyperglycemic state (HHS, sometimes labeled "hyperosmolar non-ketotic state" or HONK) is much more common in type 2 diabetes and features increased plasma osmolarity (above 320 mosm/kg) due to profound dehydration and concentration of the blood; mild acidosis and ketonemia may occur in this state, but not to the extent observed in ...
Hyperosmolar nonketotic coma (usually type 2) in which an extremely high blood sugar level and dehydration alone are sufficient to cause unconsciousness. In most medical contexts, the term diabetic coma refers to the diagnostical dilemma posed when a physician is confronted with an unconscious patient about whom nothing is known except that ...

Hyperosmolar coma A coma (loss of consciousness) related to high levels of glucose (sugar) in the blood and requiring emergency treatment. A person with this condition is usually older and weak from loss of body fluids and weight. The person may or may not have a previous history of diabetes. Ketones (acids) are not typically present in the urine.
