How to Handle Severe Hypoglycemia: A Step-by-Step Emergency Guide

Severe hypoglycemia, or very low blood sugar, is a dangerous condition that can occur in people with diabetes who take insulin or certain other medications. It requires immediate action to prevent serious complications such as seizures, loss of consciousness, and even brain damage. This guide provides a step-by-step approach to effectively manage a severe hypoglycemic episode. Understanding the symptoms, having a plan, and knowing how to administer treatment are crucial for anyone caring for someone at risk of hypoglycemia.

Understanding Severe Hypoglycemia

Severe hypoglycemia occurs when blood glucose levels drop to a point where the individual cannot treat themselves. This typically means they are confused, disoriented, unconscious, or having seizures. The threshold for severe hypoglycemia is generally considered to be below 70 mg/dL (3.9 mmol/L), but symptoms can vary widely among individuals.

Risk Factors and Common Causes

Several factors can increase the risk of severe hypoglycemia:

Insulin Use: Taking too much insulin, not adjusting insulin doses appropriately for meals or exercise, or injecting insulin incorrectly.
Oral Medications: Certain diabetes medications, such as sulfonylureas (e.g., glipizide, glyburide), can cause hypoglycemia.
Missed or Delayed Meals: Skipping meals or not eating enough carbohydrates can lead to low blood sugar.
Exercise: Physical activity without adequate carbohydrate intake.
Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream.
Kidney or Liver Problems: These conditions can affect how medications are processed in the body.

Recognizing the Symptoms

Being able to recognize the symptoms of hypoglycemia is critical. Symptoms can vary, but common signs include:

Confusion and Disorientation: Difficulty thinking clearly or following instructions.
Loss of Coordination: Stumbling or difficulty walking.
Blurred Vision: Visual disturbances.
Sweating: Profuse sweating, even in a cool environment.
Shaking or Tremors: Uncontrollable shaking.
Rapid Heartbeat: A racing pulse.
Seizures: Involuntary muscle contractions and loss of consciousness.
Loss of Consciousness: Unresponsiveness.

Recognizing these symptoms early can help prevent the condition from progressing to a severe state.

Step-by-Step Guide to Handling a Severe Hypoglycemic Episode

When someone experiences severe hypoglycemia, follow these steps immediately:

Step 1: Assess the Situation

Check for Responsiveness: Gently try to wake the person and see if they respond to verbal or physical stimuli.
Look for Medical Identification: Check if the person is wearing a medical ID bracelet or necklace indicating they have diabetes.
Observe Symptoms: Note the specific symptoms the person is exhibiting (e.g., seizures, unconsciousness, confusion).

Step 2: Call for Emergency Medical Assistance

Dial Emergency Services: Immediately call your local emergency number (e.g., 911 in the US, 112 in Europe). Clearly state that the person is experiencing severe hypoglycemia and is unresponsive or having seizures.
Provide Location Details: Give the dispatcher the exact location to ensure prompt arrival of medical assistance.
Stay on the Line: Follow the dispatcher’s instructions and provide any additional information they may require.

Step 3: Administer Glucagon (If Available)

Glucagon is a hormone that helps raise blood sugar levels quickly. It is available by prescription and should be part of the emergency kit for anyone at risk of severe hypoglycemia.

Locate the Glucagon Kit: Ensure you know where the glucagon kit is stored and how to access it quickly.
Prepare the Injection: Follow the instructions provided in the glucagon kit. Typically, this involves mixing the powder with the liquid solution.
Administer the Injection:
- Unconscious Person: Turn the person onto their side to prevent choking if they vomit. Inject glucagon into the upper arm, thigh, or buttock.
- Conscious but Uncooperative Person: If the person is conscious but resisting, it's still crucial to administer the injection, but do so gently and safely.
Note the Time: Record the time of the glucagon injection, as this information will be important for medical personnel.
Monitor breathing: After administrating Glucagon it is important to check breathing.

Step 4: Provide Information to Emergency Responders

Share Medical History: Inform the paramedics or EMTs that the person has diabetes and was given glucagon.
List Symptoms Observed: Describe the symptoms you witnessed before and after administering glucagon.
Provide Medication List: If possible, provide a list of the person’s medications.
Offer Contact Information: Give the emergency responders the contact information of the person’s doctor or emergency contact.

Step 5: Follow-Up Care

Monitor Blood Sugar Levels: After the person regains consciousness, check their blood sugar level as soon as possible.
Provide a Carbohydrate Source: Once they are alert and able to swallow, give them a fast-acting carbohydrate source, such as juice, glucose tablets, or regular soda.
Monitor for Recurrence: Continue to monitor the person closely for the next few hours to ensure their blood sugar does not drop again.
Consult a Healthcare Professional: Advise the person to consult with their doctor or diabetes educator to determine the cause of the hypoglycemia and adjust their treatment plan accordingly.

What NOT to Do During a Severe Hypoglycemic Episode

It's equally important to know what actions to avoid during a severe hypoglycemic episode:

Do NOT Inject Insulin: Giving insulin to someone with low blood sugar will worsen the situation.
Do NOT Give Food or Drink to an Unconscious Person: This can cause choking or aspiration, which can be life-threatening.
Do NOT Leave the Person Alone: Stay with the person until emergency medical assistance arrives and takes over their care.

Preparing for Future Hypoglycemic Episodes

Prevention is key. Work with your healthcare provider to create a personalized plan to manage and prevent hypoglycemia. This plan should include:

Regular Blood Glucose Monitoring

Frequency: Check blood glucose levels regularly, especially before meals, before bedtime, and before, during, and after exercise.
Tools: Use a reliable blood glucose meter and ensure it is properly calibrated.
Record Keeping: Keep a log of blood glucose readings to identify patterns and trends.

Medication Management

Adherence: Take insulin and oral medications as prescribed by your doctor.
Timing: Pay close attention to the timing of medication administration in relation to meals and activities.
Adjustments: Work with your healthcare provider to adjust medication dosages as needed based on blood glucose levels, activity, and overall health.

Meal Planning

Balanced Diet: Eat regular, balanced meals and snacks containing carbohydrates, protein, and fat.
Consistent Timing: Eat meals and snacks at consistent times each day.
Carbohydrate Counting: Learn to count carbohydrates to match insulin dosages and maintain stable blood glucose levels.

Exercise Precautions

Check Blood Sugar Before Exercise: Monitor blood glucose levels before starting any physical activity.
Have a Snack: If blood sugar is low before exercise, eat a carbohydrate-rich snack.
Monitor During Exercise: Check blood sugar periodically during prolonged exercise.
Adjust Insulin: Work with your healthcare provider to adjust insulin dosages on days when you plan to exercise.

Emergency Preparedness

Glucagon Kit: Keep a glucagon kit readily available at home, at work, and when traveling.
Train Family and Friends: Educate family members, friends, and coworkers on how to recognize and treat severe hypoglycemia.
Medical ID: Wear a medical ID bracelet or necklace indicating you have diabetes.
Emergency Contacts: Keep a list of emergency contacts readily available.

The Importance of Continuous Glucose Monitoring (CGM)

Continuous Glucose Monitoring (CGM) systems have become increasingly popular and can be invaluable for managing diabetes and preventing hypoglycemia.

How CGM Works

Real-Time Readings: CGMs continuously track glucose levels and provide real-time readings.
Trends and Patterns: CGMs can show the direction and speed of glucose changes, helping to identify trends and patterns.
Alerts and Alarms: CGMs can be programmed to alert you when glucose levels are too high or too low.

Benefits of CGM

Improved Glucose Control: CGMs can help individuals better manage their glucose levels and reduce the risk of both hypoglycemia and hyperglycemia.
Reduced Risk of Severe Hypoglycemia: The real-time monitoring and alerts can help prevent glucose levels from dropping too low.
Greater Flexibility: CGMs provide greater flexibility in meal planning and exercise, as they allow for more precise adjustments to insulin dosages.
Data-Driven Decision Making: CGMs provide valuable data that can be used to make informed decisions about medication, diet, and lifestyle.

Example Scenario: Using CGM to Prevent Hypoglycemia

John uses a CGM system to manage his type 1 diabetes. Before going for a run, his CGM alerts him that his glucose level is trending downward. He eats a small snack containing carbohydrates and protein. His CGM continues to monitor his glucose levels during his run, and he avoids hypoglycemia.

Conclusion

Effectively managing severe hypoglycemia requires prompt recognition, quick action, and preparedness. By understanding the symptoms, following the step-by-step guide for emergency treatment, and implementing preventative measures, you can significantly reduce the risk of serious complications. Keep glucagon readily available, educate those around you, and work closely with your healthcare team to develop a comprehensive diabetes management plan. Continuous Glucose Monitoring can also be a game-changer for many, helping to maintain optimal glucose levels and prevent dangerous drops. Remember, when in doubt, always seek immediate medical assistance. Your proactive approach can save a life.
