Which of the following is a symptom of hyperglycemia?

Frequent urination is a classic symptom of hyperglycemia, which is a condition characterized by elevated levels of glucose in the blood. When blood sugar levels rise significantly, the kidneys work to filter out the excess glucose. The body then expels this excess glucose along with water through urine, leading to increased urination or polyuria.

This process can also result in dehydration, which can further contribute to feelings of thirst and the urge to drink more fluids. The physiological response to high blood sugar is thus closely linked to this symptom. Understanding the relationship between high glucose levels and these bodily responses is crucial for recognizing and managing diabetes and related conditions effectively.
