Classic symptoms of hypoglycemia include which of the following?

• A. Nausea
• B. Sweating and confusion
• C. Chest pain
• D. Shortness of breath

Answer: (B)

Hypoglycemia triggers two main effects: the body's automatic stress response and the brain’s lack of glucose. The autonomic response causes sweating as epinephrine is released, while the brain’s glucose deficit leads to confusion and trouble thinking. Because sweating reflects the adrenergic reaction and confusion reflects neuroglycopenia, the combination of sweating and confusion is a classic sign of low blood sugar. Nausea can occur in many conditions and isn’t as specific, and chest pain or shortness of breath point more to cardiac or respiratory issues.
