What is the recommended course of action if a patient experiences severe hypoglycemia?

When a patient experiences severe hypoglycemia, the recommended course of action is to give intravenous (IV) glucose. This method is particularly effective because it allows for rapid administration and immediate absorption, which is crucial in treating severe hypoglycemia. In situations where a patient is unable to safely consume oral glucose—due to confusion, unconsciousness, or inability to swallow—IV glucose provides a direct and reliable means to quickly elevate blood sugar levels and restore normal glucose physiology.

Oral glucose is typically suitable for mild to moderate hypoglycemia, and increasing insulin dosage would only exacerbate the problem. Waiting for symptoms to resolve is not advisable since severe hypoglycemia can lead to life-threatening complications if not treated promptly and effectively.
