Hyperosmolar nonketotic coma occurs in people with diabetes. This condition is life-threatening, so it is important to seek medical attention immediately if you think you have any symptoms of an impending hyperosmolar nonketotic coma.
Hyperosmolar nonketotic coma is a complication of hyperosmolar hyperglycemic nonketotic syndrome (HHNS), in which your body tries to get rid of excess blood glucose by passing it through your urine. When HHNS is severe, it can lead to seizures, coma, and eventually death.
The following factors are thought to increase the risk of hyperosmolar nonketotic coma:
