Which is an early warning symptom of hypoglycemia and should prompt further assessment?

• A. Headache
• B. Cold and clammy skin
• C. Hot and dry skin
• D. Shortness of breath

Answer: (A)

Recognizing early signs of hypoglycemia and knowing when to assess blood glucose is essential. Cold and clammy skin is a classic early cue because it reflects the body's sympathetic response to falling glucose, often accompanied by sweating and tremors. This autonomic activation signals that glucose is slipping and should prompt an immediate glucose check and, if needed, quick treatment. Headache can occur with many conditions and is not specific enough to reliably indicate hypoglycemia early. Hot and dry skin points more toward high blood glucose or dehydration, not hypoglycemia, and shortness of breath suggests other problems such as respiratory or cardiac issues. In older adults, symptoms can be subtle or atypical, but the presence of autonomic signs like cold, clammy skin is a meaningful prompt to assess glucose promptly.
