Which is used for unconscious hypoglycemia?

• A. GTN spray
• B. Adrenaline
• C. Glucogel
• D. Glucagon

Answer: (D)

In unconscious hypoglycemia, the priority is to raise blood glucose quickly when the person cannot swallow. Glucagon is the best choice because it acts fast by signaling the liver to convert stored glycogen into glucose and release it into the bloodstream. It can be given as a simple intramuscular injection, and its effect typically begins within a few minutes, which is crucial when consciousness is lost.

Glucogel is designed for conscious patients who can swallow, so it’s not suitable for someone who is unconscious and at risk of choking. GTN spray is for chest pain and has no role in correcting low blood glucose. Adrenaline is used in other emergencies like severe allergic reactions or cardiac arrest, not for treating hypoglycemia.

After regaining consciousness, the person should receive a carbohydrate snack or meal and medical follow-up to prevent recurrence and adjust diabetes management if needed.
