If a diabetic is unconscious, what is the best immediate action?

Administering glucagon intramuscularly is the most appropriate immediate action for an unconscious diabetic patient. When a person with diabetes becomes unconscious, it often indicates severe hypoglycemia, which is a dangerously low blood sugar level. Glucagon is a hormone that prompts the liver to release stored glucose into the bloodstream, rapidly increasing blood sugar levels. This can potentially restore consciousness and prevent further complications.

Prompt action is critical in this scenario because airway protection and prompt correction of hypoglycemia can be life-saving. While calling emergency services is essential if the situation does not improve, the immediate need is to correct the low blood sugar. Feeding food or waking the patient gently are not effective interventions in this state, as they may pose risks if the person is unable to swallow or regain consciousness.
