Which feature differentiates Hyperglycemic-Hyperosmolar State from Diabetic Ketoacidosis?

• A. Presence of ketosis
• B. Absence of significant ketones
• C. Lower glucose levels
• D. Rapid onset of symptoms

Answer: (B)

Ketone production is the key difference. In Hyperglycemic-Hyperosmolar State, there is enough insulin to suppress excessive fat breakdown, so ketone bodies are not produced in significant amounts and metabolic acidosis is minimal. In Diabetic Ketoacidosis, marked insulin deficiency drives lipolysis and hepatic ketogenesis, leading to significant ketosis and acidosis. Therefore, absence of significant ketones differentiates HHS from DKA. The presence of ketosis would point toward DKA; extremely high glucose with rapid onset tends to occur more with DKA, while HHS commonly presents with even higher glucose and a slower onset due to more profound dehydration. Lower glucose levels are not typical for HHS.
