An unconscious diabetic should be given food and liquids.

In a situation where a person with diabetes is unconscious, it is essential to refrain from administering food or liquids. The primary reason for this is the risk of choking, as an unconscious individual may not have control over their swallowing reflex. Additionally, if the person is unable to protect their airway, giving oral intake could lead to aspiration, where food or liquid enters the airway, potentially causing serious complications.

Instead of providing food or liquids, the appropriate action would be to seek immediate medical attention. The unconscious state in a diabetic could result from hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), both of which require careful evaluation and professional treatment. In cases of hypoglycemia, emergency responders can provide appropriate interventions, such as administering glucose intravenously, which is safer than trying to give oral substances.
