Sweet-smelling urine can be caused by several conditions, the most common being high blood sugar levels related to diabetes. When the body has excess glucose, it expels some of it through urine, resulting in a sweet or fruity smell. Other causes include urinary tract infections (UTIs), certain metabolic disorders like maple syrup urine disease, ketosis from high protein diets, dehydration, and even some foods or pregnancy hormones. Sweet-smelling urine should prompt a medical checkup as it can be an early sign of diabetes or an infection needing treatment.
