What is a common sign or symptom of high blood glucose?

A sluggish feeling is a common sign or symptom of high blood glucose levels, also known as hyperglycemia. When blood glucose levels are elevated, the body struggles to use the glucose for energy due to insufficient insulin or insulin resistance. This results in a lack of readily available energy for cellular processes, leading to feelings of fatigue and sluggishness.

In hyperglycemia, the body attempts to rid itself of the excess glucose through increased urine production, which can also contribute to dehydration and further feelings of tiredness. Recognizing these symptoms is essential for timely intervention, such as administering insulin or adjusting dietary intake, to prevent complications associated with uncontrolled blood sugar levels.

While profuse sweating, nausea/vomiting, and syncope may occur in other medical situations, they are more commonly associated with hypoglycemia (low blood glucose) or other conditions rather than high blood glucose, making sluggishness a more definitive indicator in this context.
