What is the osmolarity level in HHS?

Explanation:
Osmolarity measures how concentrated the blood solutes are and drives water movement between body compartments. In Hyperosmolar Hyperglycemic State, extreme hyperglycemia adds a large solute load to the blood, so water shifts out of cells and the serum becomes highly concentrated. This typically pushes serum osmolarity above 320 mOsm/L, often substantially higher. So the best answer is that osmolarity is greater than 320 mOsm/L. Values around normal (about 300 mOsm/L) or exactly at 320 are not characteristic of HHS, and the key feature is a markedly elevated osmolarity exceeding 320.
