Immediate Steps to Take for Severe Hypoglycemia (Low Blood Sugar)

Related reading: The Ideal Blood Sugar Range For Adults Seniors And Children

Hypoglycemia, or low blood sugar, is a dangerous condition that occurs when the level of glucose (sugar) in your blood drops too low. It's particularly common among people with diabetes who take insulin or certain oral medications. Severe hypoglycemia can lead to seizures, loss of consciousness, and, in rare cases, even death. Therefore, knowing how to recognize and immediately address severe hypoglycemia is crucial for both individuals with diabetes and their caregivers. This article will guide you through the essential steps to take when someone experiences a severe hypoglycemic episode, ensuring you are well-prepared to handle this critical situation.

Recognizing Severe Hypoglycemia

Before we delve into the immediate steps, it's important to understand the symptoms of severe hypoglycemia. Unlike mild or moderate hypoglycemia, where a person might experience shakiness, sweating, or dizziness, severe hypoglycemia involves more pronounced symptoms that often require external assistance.

Signs and Symptoms of Severe Hypoglycemia:

  • Loss of Consciousness: The individual may faint or become unresponsive.
  • Seizures: Uncontrolled muscle contractions may occur.
  • Confusion or Disorientation: Extreme difficulty in thinking clearly or understanding surroundings.
  • Inability to Swallow: Making it impossible to take oral medication or food.

Recognizing these signs promptly is key to preventing further complications.

Step-by-Step Guide to Immediate Action

When you encounter someone experiencing severe hypoglycemia, swift action is essential. Here’s a step-by-step guide:

1. Do Not Attempt to Give Food or Drink Orally

If the person is unconscious, seizing, or unable to swallow, do not attempt to give them anything by mouth. This is because of the risk of choking or aspiration (inhaling fluids into the lungs), which can lead to serious complications like pneumonia.

2. Administer Glucagon

Glucagon is a hormone that raises blood sugar levels by stimulating the liver to release stored glucose into the bloodstream. It is available as an injectable or nasal spray medication and is typically prescribed to individuals at risk of severe hypoglycemia.

  • If Glucagon Kit is Available:

    • Injectable Glucagon: Follow the instructions in the glucagon kit for preparing and administering the injection. Typically, this involves mixing the glucagon powder with the diluent and injecting it into the thigh, buttock, or arm muscle.
    • Nasal Glucagon: Follow the product instructions for the nasal spray device. Insert the nozzle into one nostril and depress the plunger to deliver the dose.

3. Call for Emergency Medical Assistance

Immediately after administering glucagon, or if you don't have glucagon available, call your local emergency number (e.g., 911 in the US). Clearly explain the situation and the symptoms the person is experiencing. Providing accurate information can help the emergency responders prepare appropriately.

4. Monitor the Individual

While waiting for medical assistance, continue to monitor the person's breathing and vital signs. If they are not breathing, begin CPR (cardiopulmonary resuscitation) if you are trained to do so.

5. Provide Information to Emergency Responders

When the emergency medical team arrives, provide them with as much information as possible, including:

  • The person’s medical history, especially if they have diabetes.
  • What you observed (symptoms of hypoglycemia).
  • What actions you took (administering glucagon).
  • Any known allergies or other medical conditions.

Understanding Glucagon

Glucagon is a critical tool in managing severe hypoglycemia. It acts quickly to raise blood sugar levels, often within 10-15 minutes. Here's what you need to know:

Who Needs Glucagon?

  • Individuals with diabetes who are at risk of severe hypoglycemia, especially those who take insulin or sulfonylureas.
  • Caregivers, family members, and close contacts of these individuals should be trained on how to administer glucagon.

Types of Glucagon

  • Injectable Glucagon: The traditional form of glucagon that requires reconstitution before injection.
  • Nasal Glucagon (Baqsimi): A more convenient form that is administered as a nasal spray, requiring no mixing or injection.

How Glucagon Works

Glucagon stimulates the liver to convert stored glycogen into glucose, which is then released into the bloodstream. This raises blood sugar levels, counteracting the effects of hypoglycemia. It's essential to note that glucagon is most effective when there are adequate glycogen stores in the liver. Therefore, it might be less effective in individuals who are malnourished or have liver disease.

Important Considerations

  • Storage: Always store glucagon kits according to the manufacturer's instructions, typically in a cool, dry place away from direct sunlight.
  • Expiration: Check the expiration date regularly and replace the kit before it expires.
  • Side Effects: Common side effects of glucagon may include nausea and vomiting. It’s important to turn the person on their side to prevent choking if vomiting occurs.
  • Ineffectiveness: If the person does not respond to glucagon within 15 minutes, and emergency services have been contacted, do not administer a second dose unless specifically instructed by medical personnel.
  • Medical Alert: Ensure the person wears a medical ID bracelet or necklace indicating they have diabetes and are at risk of hypoglycemia. This can provide crucial information to first responders if the person is found alone and unresponsive.

Preventative Measures to Avoid Severe Hypoglycemia

While knowing how to treat severe hypoglycemia is essential, preventing it in the first place is even more important. Here are some strategies for managing blood sugar levels and reducing the risk of severe hypoglycemia:

1. Regular Blood Glucose Monitoring

  • Check blood sugar levels frequently, especially before meals, after exercise, and before bedtime.
  • Use a continuous glucose monitor (CGM) for real-time blood sugar readings and alerts for low glucose levels.

2. Consistent Meal Timing and Carbohydrate Intake

  • Eat meals and snacks at consistent times each day to avoid fluctuations in blood sugar levels.
  • Work with a registered dietitian or diabetes educator to develop a meal plan that balances carbohydrate intake with medication dosages.

3. Adjust Medication Dosages as Needed

  • Work closely with your healthcare provider to adjust insulin or oral medication dosages based on blood sugar levels, activity levels, and dietary habits.
  • Learn how to adjust insulin dosages for exercise, illness, and stress.

4. Educate Yourself and Others

  • Understand the signs and symptoms of hypoglycemia and hyperglycemia (high blood sugar).
  • Educate family members, friends, and coworkers on how to recognize and treat hypoglycemia.
  • Carry glucose tablets or other fast-acting carbohydrates with you at all times.

5. Be Prepared for Exercise

  • Check blood sugar levels before, during, and after exercise.
  • Carry a source of fast-acting carbohydrates with you during exercise.
  • Adjust insulin dosages or carbohydrate intake as needed for planned physical activity.

6. Limit Alcohol Consumption

  • Alcohol can lower blood sugar levels, especially when consumed on an empty stomach.
  • If you choose to drink alcohol, do so in moderation and always with food.
  • Monitor blood sugar levels closely after drinking alcohol.

Practical Scenarios and Examples

Let's consider a few scenarios to illustrate how these steps can be applied in real-life situations:
