– Not putting anything in a person’s mouth: During an episode, an individual may be disoriented or experiencing seizures. It is important to remember not to force anything into their mouth, as it can lead to choking or aspiration.

3.2 Waking Up the Person:

In some cases, individuals experiencing nocturnal hypoglycemia may not wake up or respond due to the severity of their symptoms. In such situations, immediate action must be taken to address the crisis.

– Calling 911: If the person remains unresponsive or if you are unable to administer emergency treatment effectively, call emergency services immediately. They are equipped to handle medical emergencies and can provide necessary assistance.

– Giving fast-acting glucose sources: If the person is conscious and able to take oral glucose, provide them with fast-acting glucose sources such as hard candy, fruit juice, or glucose paste/tablets. These readily available options can help raise blood sugar levels swiftly.

– Eating a meal: Once the individual has regained consciousness and their blood sugar levels have stabilized, it is advisable to provide them with a balanced meal. This will help sustain blood sugar levels throughout the night and reduce the risk of further nocturnal hypoglycemia episodes.

– Checking blood glucose levels: After a nocturnal hypoglycemia episode, it is crucial to monitor blood glucose levels to ensure they remain stable. Regular testing is important to detect any potential fluctuations, enabling proactive management and prevention of future episodes.

3.3 Follow-up with a Doctor:

Reaching out to a medical professional after a nocturnal hypoglycemia episode is vital for comprehensive follow-up care. – Calling the doctor: Inform your healthcare provider about the episode as soon as possible.

They can provide guidance on further steps and potentially adjust insulin dosages or medication if necessary. – Determining the cause of the episode: Working with your doctor, determine the underlying cause of the nocturnal hypoglycemia episode.

Identifying the triggers (such as skipping meals or inadequate insulin dosages) can aid in prevention. – Adjusting insulin or medication: Based on the evaluation of the episode and discussions with your healthcare provider, necessary adjustments may be made to your insulin regimen or other medications to reduce the risk of future nocturnal hypoglycemia episodes.

– Setting alarms for blood glucose testing: It may be beneficial to set alarms throughout the night to wake up and test blood glucose levels. This extra precaution can help prevent hypoglycemia or enable early intervention.


Nocturnal hypoglycemia demands immediate action, preparedness, and proactive measures to ensure the safety and well-being of individuals affected by this condition. By having an emergency glucagon kit readily available, knowing how to use it, and being familiar with the necessary steps to wake up and assist a person experiencing an episode, we can minimize the risks associated with nocturnal hypoglycemia.
