Which of the following is a common symptom of hyperglycemia?

In the context of hyperglycemia, increased thirst is indeed a common symptom. When blood glucose levels are elevated, the body attempts to eliminate excess glucose through the kidneys, leading to increased urination. This loss of fluid can result in dehydration, which triggers thirst as the body seeks to restore fluid balance.

While flushed skin can occur due to various reasons, it is not a primary or distinguishing symptom of hyperglycemia. Other symptoms associated with high blood sugar levels include frequent urination, nausea and vomiting, and blurred vision; all of which can occur due to the body’s adjustments to elevated glucose levels. Frequent urination and blurred vision are particularly characteristic symptoms, reflecting physiological responses to hyperglycemia. However, when considering the symptoms collectively, increased thirst stands out as one of the most prominent and commonly recognized manifestations of hyperglycemia.
