Which of the following is a sign a dentist should recognize as suggestive of hypoglycemia in a patient during treatment?

Hypoglycemia classically presents with a relatively rapid onset of adrenergic symptoms (sweating/diaphoresis, tremor, tachycardia, anxiety) and neuroglycopenic symptoms (confusion, irritability, slurred speech), requiring prompt recognition and treatment with oral glucose (if the patient is conscious and able to swallow safely).
