<unk>  is a life-threatening but reversible form of coma found in people with diabetes mellitus. Three different types of<unk>  are identified: #Severe low blood sugar in a<unk>  person<unk>  ketoacidosis (usually type 1) advanced enough to result in unconsciousness from a combination of a severely increased blood sugar level, dehydration and shock, and exhaustion #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<unk>  refers to the diagnostical dilemma posed when a physician is confronted with an unconscious patient about whom nothing is known except that they have diabetes. An example might be a physician working in an emergency department who receives an unconscious patient wearing a medical identification tag saying<unk> . Paramedics may be called to rescue an unconscious person by friends who identify them as<unk> . Brief descriptions of the three major conditions are followed by a discussion of the diagnostic process used to distinguish among them, as well as a few other conditions which must be considered. An estimated 2 to 15 percent of people with diabetes will suffer from at least one episode of<unk>  in their lifetimes as a result of severe hypoglycemia.
