What should be done if a patient's blood glucose is low?

When a patient's blood glucose is low, the appropriate action is to provide glucose or carbohydrates to quickly elevate the blood sugar levels. This response is critical because hypoglycemia can lead to serious complications, including loss of consciousness or seizures if not treated promptly. Administering glucose helps restore adequate blood sugar levels, allowing the body's cells to function properly and preventing any further adverse effects.

Holding insulin is also a valid consideration since administering it would exacerbate the low blood sugar condition. However, the primary intervention to address hypoglycemia is the administration of glucose or carbohydrates to guide the patient back to a safe blood glucose level. Monitoring for further symptoms is an important follow-up measure but does not replace the urgent need to correct the low glucose level first.
