Which of the following is a symptom of hypoglycemia?

• A. Rash
• B. Fatigue
• C. Shaky
• D. Weight gain

Answer: (C)

Shakiness is a hallmark sign of hypoglycemia because when glucose dips, the body mounts an adrenergic response that releases adrenaline. This fight-or-flight signal makes muscles tremble and creates a sense of jitteriness, fast heartbeat, and anxiety—early clues that blood sugar is too low. Rash isn’t related to low glucose and points to skin conditions or allergies. Fatigue can accompany many issues but isn’t a specific or reliable indicator of hypoglycemia. Weight gain isn’t a direct symptom of low blood sugar; it’s more linked to longer-term energy balance and insulin effects. So the tremor-like shaking best fits the pattern of hypoglycemia.
