Which odor is commonly associated with diabetic ketoacidosis?

• A. Pear
• B. Fruity breath
• C. Rotten eggs
• D. No odor

Answer: (B)

In diabetic ketoacidosis, a fruity breath is a classic sign because ketone bodies accumulate and one of them, acetone, is volatile and exhaled in the breath. When insulin is severely deficient, the body turns to fat for energy, producing ketones in the liver. Acetone specifically gives that characteristic fruity odor you can detect on exhalation, often alongside other DKA findings like dehydration, polyuria, polydipsia, nausea, abdominal pain, and rapid breathing. So the fruity breath helps point to DKA, whereas a pear scent or rotten-egg odor isn’t typical for this condition, and having no odor would not align with the ketone buildup seen in DKA.
