What happens if proteins and ketones are detected in urine?

The presence of proteins in urine, known as proteinuria, can indicate kidney damage or disease, as healthy kidneys typically prevent protein from leaking into urine. Ketones in urine, or ketonuria, often suggest that the body is using fat for energy instead of carbohydrates, which can occur during fasting, prolonged exercise, or uncontrolled Diabetes. When both proteins and ketones are detected, it may signal serious health issues, such as diabetic ketoacidosis or kidney disease, necessitating further medical evaluation.
