Which of the following is NOT a symptom of hyperglycemia?

1. Thirst

2. Fruity breath

3. Drowsiness

4. Cold, clammy skin

The correct answer is: Cold, clammy skin

Cold, clammy skin is not a symptom of hyperglycemia. Hyperglycemia, or high blood sugar, typically leads to symptoms that result from insufficient insulin or increased levels of glucose in the bloodstream. Common symptoms of hyperglycemia include excessive thirst, known as polydipsia, which is a response to increased blood glucose levels; fruity breath, often associated with diabetic ketoacidosis; and drowsiness stemming from the body's inability to efficiently use glucose for energy. In contrast, cold, clammy skin is generally indicative of hypoglycemia, or low blood sugar. When blood sugar drops, the body releases adrenaline, leading to sweating and cold skin as part of a fight-or-flight response. This distinction is crucial in recognizing and responding to blood glucose level changes effectively. Understanding these symptoms can aid in the timely identification and management of both hyperglycemia and hypoglycemia in individuals with diabetes.
