What is indicated by the presence of glucose in urine?

1. Dehydration

2. Possible uncontrolled diabetes

3. Acute gastrointestinal infections

4. None of the above

The correct answer is: Possible uncontrolled diabetes

The presence of glucose in urine, known as glucosuria, is commonly associated with possible uncontrolled diabetes. When blood glucose levels exceed the renal threshold, the kidneys cannot reabsorb all the glucose, leading to its excess in urine. This can indicate that the individual has not managed their blood sugar levels effectively, which is characteristic of uncontrolled diabetes. Dehydration can cause increased urine concentration but is not directly linked to the presence of glucose. Similarly, acute gastrointestinal infections might lead to symptoms like diarrhea or vomiting, but they do not typically produce glucose in urine unless linked with metabolic changes that are not straightforward. Thus, the most accurate indication of glucosuria aligns with the possibility of uncontrolled diabetes.
