Which of the following is a sign of hypoglycemia?

Fever
Diaphoresis
Skin rash
Bradycardia

The correct answer is: Diaphoresis

Diaphoresis, or excessive sweating, is a classic sign of hypoglycemia. When blood sugar levels drop, the body responds by releasing adrenaline (epinephrine), which triggers the fight-or-flight response. This response leads to physical symptoms such as sweating, increased heart rate, and tremors. In the context of hypoglycemia, diaphoresis occurs as a means for the body to alert the individual to a critical health condition that needs to be addressed quickly. Fever, on the other hand, is not directly related to low blood sugar levels but may suggest an infection or another medical condition. Skin rash typically indicates an allergic reaction or dermatological issue, and bradycardia refers to a slower-than-normal heart rate, which is not a prominent feature of hypoglycemia. Understanding these distinctions helps in recognizing the symptoms associated with different medical emergencies.
