Which symptom is most characteristic of hypoglycemia?

• A. Polyphagia
• B. Polydipsia
• C. Shakiness
• D. Fruity breath

Answer: (C)

Shakiness reflects the adrenergic warning signal that appears when blood glucose falls. When glucose dips, the body releases adrenaline, causing tremors, palpitations, sweating, and anxiety as it tries to raise blood sugar quickly. Among the options, this tremor is the most characteristic early sign of hypoglycemia because it directly results from that sympathetic response. Hunger can occur but is less specific, while thirst and fruity breath point more toward high blood glucose and ketosis rather than low glucose. If hypoglycemia isn’t treated promptly, symptoms can progress to confusion or fainting, but the tremor is the classic early cue.
