What is fruity urine smell?

Fruity urine smell is a medical sign indicating a metabolic disorder causing elevated levels of ketones in the urine. Ketones are produced during fat breakdown for energy when there is insufficient glucose in the body. This condition called ketoacidosis is common in diabetes but may also be caused by other medical conditions such as starvation, chronic alcoholism, severe dehydration, and strenuous exercise. As ketones are excreted in the urine, the smell of the urine becomes sweet or fruity. If you notice a persistent fruity urine smell, it's essential to seek medical attention to identify and treat the underlying cause.
