Fruity-Smelling Urine: Sign of Ketosis, Diabetic Ketoacidosis, or Other Metabolic Issues
A sweet, fruity urine odor signals ketonuria—elevated ketones from fat breakdown due to insufficient glucose utilization. Common causes:
- Diabetic ketoacidosis (DKA): Medical emergency in uncontrolled diabetes.
- Starvation/fasting, ketogenic diet
- Chronic alcoholism
- Severe dehydration
- Prolonged strenuous exercise
Persistent fruity smell requires urgent medical evaluation to identify and treat the underlying cause, especially if accompanied by nausea, abdominal pain, confusion, or rapid breathing.
