Ketones in urine refer to the presence of ketone bodies, which are produced when the body breaks down fat for energy instead of carbohydrates. This usually happens when there is a lack of glucose, such as during fasting, a low-carbohydrate diet, or uncontrolled diabetes. The presence of ketones in urine can be detected through a test and may indicate conditions like diabetes, starvation, or a low-carb diet. High levels of ketones can be a sign of a medical issue and may require attention.
