How much oral glucose is generally administered to a patient?

Administering 15g of oral glucose is the standard practice for treating hypoglycemia in alert patients who are able to swallow. This dosage is sufficient to raise blood glucose levels effectively without the risk of causing hyperglycemia. In emergency settings, it's crucial to provide a dosage that balances prompt relief of symptoms with safety.

Using 15g allows for the rapid absorption and quick physiological response needed in the context of a hypoglycemic episode. If a patient does not respond within a specific timeframe, additional doses may be administered as needed to ensure that blood glucose levels are adequately controlled.

Administering less than this amount might not produce the desired effect in quickly elevating blood sugar levels, while higher doses could lead to unnecessary fluctuations and complications in glucose levels.
