Hyperosmolar
Introduction
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.
