Which of the following is a common symptom of hypoglycemia that prompts immediate treatment?

• A. Tremor.
• B. Nausea.
• C. Rash.
• D. Blurred vision.

Answer: (A)

Tremor is a common early warning sign when blood glucose falls. The body reacts to low glucose by releasing adrenaline, which triggers shakiness, sweating, and a racing heartbeat. This autonomic response is one of the most recognizable cues that glucose is too low, prompting people to treat right away with a fast-acting carbohydrate to raise blood sugar before it worsens.

Other symptoms like nausea, rash, or blurred vision can occur in various conditions and are not as specific or immediate in signaling the need for quick treatment. Nausea can accompany many illnesses; a rash usually points to an allergic or infectious process; blurred vision may appear with severe hypoglycemia or other problems but isn’t as reliable for prompting immediate self-treatment as tremor.
