Which of the following is a symptom of hyperglycemia?

Frequent urination is a key symptom of hyperglycemia, which refers to abnormally high levels of glucose in the blood. When blood sugar levels rise significantly, the kidneys work to filter out the excess glucose, leading to increased urine production. This process is known as osmotic diuresis, where the high concentration of glucose in the renal tubules draws water into the urine, resulting in the frequent need to urinate.

Understanding hyperglycemia is important, especially in the context of diabetes management, as it can lead to further complications if not addressed. Other symptoms typically associated with hyperglycemia may include increased thirst, fatigue, and blurred vision, but frequent urination is particularly significant as it can indicate the severity of the condition.
