A school-age girl experiences tingling in the mouth and lips with anxiety but no trauma. Which condition is most likely?

• A. Hypoglycemia
• B. Hyperventilation syndrome
• C. Panic attack
• D. Seizure

Answer: (B)

Rapid breathing driven by anxiety can cause hyperventilation, which lowers carbon dioxide in the blood. This respiratory alkalosis changes blood chemistry and nerves, leading to tingling around the mouth and lips that is classic for hyperventilation syndrome. The presence of anxiety with perioral tingling, without trauma or other focal signs, fits this pattern best. Hypoglycemia would more often bring symptoms like dizziness, sweating, hunger, or confusion; a panic attack can include intense fear and autonomic symptoms but the specific tingling from alkalosis points to hyperventilation; a seizure would usually involve convulsions or loss of consciousness rather than isolated tingling with anxiety. Managing involves reassuring the patient and guiding slow, deep diaphragmatic breathing to restore CO2 levels. If episodes recur, assess for underlying anxiety or other triggers.
