Which of the following signs would help distinguish hypoglycaemia from other emergencies in a dental setting?

• A. Trembling and sweating
• B. Chest pain
• C. Severe hypertension
• D. Hearing loss

Answer: (A)

When glucose levels drop, the body triggers a quick sympathetic response, leading to signs like trembling and sweating. These autonomic symptoms are classic early clues of hypoglycemia and help set it apart from other dental emergencies that would show different features, such as chest pain suggesting a cardiac event or very high blood pressure indicating a hypertensive crisis. Hearing loss is not a typical sign of an acute emergency in this setting. So the presence of trembling and sweating points you toward hypoglycemia, especially if the patient has diabetes or is insulin-treated. If this is suspected, treat with a fast-acting carbohydrate promptly and monitor, then seek further medical help if needed.
