Can doctors give glucose to a patient orally also what are the conditions for that?

Yes, doctors can give glucose to a patient orally, particularly if the patient is conscious and able to swallow safely. This is often done in cases of mild hypoglycemia, where rapid elevation of blood sugar levels is needed. However, it is important that the patient does not have any swallowing difficulties, risk of aspiration, or gastrointestinal issues that could prevent proper absorption. In more severe cases of hypoglycemia or altered consciousness, intravenous glucose may be necessary.
