How does diabetic ketoacidosis differ from hyperosmolar hyperglycemic state in terms of ketone production?

Explanation:
Ketone production is the key difference. In diabetic ketoacidosis, there is a marked insulin deficiency that unleashes lipolysis and hepatic ketogenesis, so large amounts of ketone bodies (acetoacetate and beta-hydroxybutyrate) accumulate and drive metabolic acidosis. In hyperosmolar hyperglycemic state, there is enough insulin to largely suppress lipolysis, so ketogenesis is minimal despite very high glucose, leading to little or no ketosis. That’s why DKA features significant ketosis, while HHS has minimal ketosis.
