Ketonuria is most commonly associated with what condition?

• A. Liver disease
• B. Urinary tract infection
• C. Renal failure
• D. Diabetes mellitus

Answer: (D)

Ketonuria occurs when ketone bodies build up in the urine because the body is burning fat for energy instead of glucose. This happens most often when insulin is deficient or not working well, as in uncontrolled diabetes mellitus, which triggers increased fat breakdown and ketone production that spills into urine. While fasting or very low-carbohydrate diets can also cause ketones to appear, diabetes mellitus is the classic and most common association in clinical veterinary practice. The other conditions listed don’t typically drive ketone production to the same extent.
