Which skin finding is typical of hypoglycemia?

• A. Cold, pale, moist, or clammy skin
• B. Warm, red, dry skin
• C. Dry, itchy skin
• D. Red, hot skin

Answer: (B)

Hypoglycemia triggers an adrenergic response that drives sweating and pallor. The skin becomes cold and clammy because you have both diaphoresis (sweating) and vasoconstriction as the body tries to raise blood glucose. This cold, pale, moist or clammy skin is a classic sign of low blood sugar and helps you recognize the emergency and act quickly to raise glucose. In contrast, warm, red, dry skin suggests dehydration or high blood glucose, not hypoglycemia. Recognizing the clammy skin pattern in a patient with symptoms like confusion, tremors, or weakness points you toward checking a blood glucose and treating with fast-acting glucose if appropriate.
