Which finding distinguishes hyperosmolar hyperglycemic state from diabetic ketoacidosis?

The distinguishing feature is the level of osmolality and ketosis. In hyperosmolar hyperglycemic state, there is very high blood glucose with marked dehydration leading to elevated plasma osmolality, but little to no ketone production and minimal acidosis. In diabetic ketoacidosis, lack of insulin drives significant ketogenesis and metabolic acidosis, with ketones present and a lower pH. So, having high osmolality with little to no ketoacidosis fits HHS best and separates it from DKA. Elevated ketones or significant acidosis point toward DKA, while hypokalemia can occur in both and doesn’t define the difference.
