Which of the following is a sign of hypoglycemia?

• A. Sweating trembling
• B. Slow loss of consciousness
• C. Rapid pulse
• D. No acetone breath

Answer: (A)

Hypoglycemia first prompts the body to release adrenaline, which drives autonomic signs like sweating and trembling. These symptoms are classic early indicators that blood glucose has fallen and the brain isn’t getting enough sugar. Among the options, sweating with trembling lines up exactly with that early autonomic response to hypoglycemia, making it the best sign.

Rapid pulse can occur as part of the same adrenaline response, but it’s less specific. Slow loss of consciousness indicates progression to a more severe state, not an initial sign. Acetone breath is associated with ketosis seen in high blood glucose states, such as diabetic ketoacidosis, not with hypoglycemia.
