Managing Severe Hypoglycemia: An Emergency Guide for Persons with Diabetes

Severe hypoglycemia, or critically low blood sugar, is a potentially life-threatening condition that can occur in people with diabetes who take insulin or certain oral medications. It is crucial to understand the symptoms, risks, and, most importantly, how to manage it effectively. This guide provides an emergency plan for individuals with diabetes and their caregivers to deal with severe hypoglycemia promptly and safely.

What is Severe Hypoglycemia?

Hypoglycemia is defined as low blood glucose, typically below 70 mg/dL. Severe hypoglycemia is when the blood sugar level is so low that the person requires assistance from another individual to recover. This might include glucagon administration or intravenous glucose. It is often accompanied by symptoms such as loss of consciousness, seizures, or an inability to swallow. Understanding the difference between mild, moderate, and severe hypoglycemia is crucial for appropriate and timely intervention.

| Level | Blood Glucose (mg/dL) | Symptoms | Action | |------------------|-----------------------|-------------------------------------------------------------|-----------------------------------------------------------------| | Mild | 60-70 | Shakiness, sweating, anxiety, hunger | Consume 15-20 grams of fast-acting carbohydrates | | Moderate | 40-60 | Confusion, irritability, difficulty concentrating, dizziness | Consume 20-30 grams of fast-acting carbohydrates; monitor closely | | Severe | <40 | Loss of consciousness, seizures, inability to swallow | Administer glucagon; call for emergency medical assistance |

Recognizing the Symptoms of Severe Hypoglycemia

Being able to recognize the signs of severe hypoglycemia is the first critical step in managing the emergency. Symptoms can vary from person to person but often include:

Loss of consciousness or unresponsiveness: The person may be unable to answer questions or follow commands.
Seizures: Involuntary muscle contractions or convulsions.
Confusion or disorientation: Marked by severe confusion and inability to think clearly.
Inability to swallow: Difficulty or complete inability to ingest food or liquids safely.
Severe motor impairment: Difficulty with coordination, walking, or moving.
Erratic Behavior: Uncharacteristic behavior that is out of the norm for the individual.

It’s important for family members, friends, and caregivers to be familiar with these signs to provide prompt assistance. Furthermore, people with diabetes should wear a medical ID indicating their condition to alert first responders.

Step-by-Step Emergency Response Plan

When someone experiences severe hypoglycemia, swift action is crucial. Here's a step-by-step guide:

Step 1: Assess the Situation

Check for responsiveness: Try to wake the person by calling their name or gently shaking them.
Look for a medical ID: Check for a bracelet, necklace, or wallet card indicating diabetes.
Do NOT attempt to give food or drink if unconscious: It could cause choking.

Step 2: Administer Glucagon (If Available and Trained)

Locate the glucagon kit: Ensure it is readily accessible if a person has been prescribed one.
Prepare the glucagon: Follow the instructions on the kit for mixing and administering the glucagon. Most kits involve mixing a powder with a liquid.
Administer the injection: Typically, glucagon is injected into the thigh, arm, or buttocks. Follow the kit's instructions on the proper injection site and technique.
Monitor closely: After the glucagon injection, closely observe the person for any changes.

Glucagon works by stimulating the liver to release stored glucose into the bloodstream. It is often provided in a kit containing a syringe and a vial of powdered glucagon. For instance, the Lilly Glucagon Emergency Kit is a commonly prescribed option.

Example of Glucagon Administration Steps: 1. Remove the cap from the vial of glucagon powder. 2. Remove the needle cover and insert the needle into the vial. 3. Inject all the liquid from the syringe into the vial. 4. Gently swirl the vial to mix the solution until it is clear. 5. Withdraw the solution back into the syringe. 6. Inject the glucagon into the thigh or another recommended site.

Step 3: Call for Emergency Medical Assistance

Call emergency services immediately (911 in the US): Provide clear information about the situation, including the person's diabetic status and any administered glucagon.
Stay on the line: Follow the dispatcher’s instructions until help arrives.

Even after administering glucagon, emergency medical services should be contacted to ensure the person receives appropriate follow-up care.

Step 4: Post-Emergency Care

Monitor blood glucose levels: Once the person regains consciousness, check their blood sugar.
Give a long-acting carbohydrate snack: Offer a snack like crackers and cheese, or a sandwich to stabilize blood sugar levels.
Seek medical evaluation: Encourage a follow-up appointment with a healthcare provider to adjust the diabetes management plan if necessary.

Example Scenario: John, a 55-year-old with type 1 diabetes, is found unconscious by his wife, Mary. Mary knows John has a glucagon kit. She quickly administers the glucagon injection and calls 911. John regains consciousness after about 10 minutes. Mary checks his blood glucose, which is now 85 mg/dL. She gives him a cheese sandwich, and they await the arrival of the paramedics for further evaluation.

Understanding Glucagon: The Emergency Hormone

Glucagon is a hormone that can quickly raise blood glucose levels. It is a critical tool in managing severe hypoglycemia. Here are some key points to understand:

How it works: Glucagon stimulates the liver to release stored glucose into the bloodstream.
Who needs it: People with diabetes at risk of severe hypoglycemia, especially those on insulin, should have a prescription for glucagon.
Administration: Glucagon is typically administered as an injection into the muscle.
Potential side effects: Common side effects may include nausea and vomiting. Turn the person on their side to prevent choking.
Availability: Glucagon kits are available by prescription from a healthcare provider.

Glucagon Nasal Spray (Baqsimi) is another option, especially for those who are needle-averse or for easier administration. It is administered by spraying it into one nostril.

| Glucagon Type | Route of Administration | Ease of Use | Advantages | Disadvantages | |---------------------|------------------------|--------------------------------------------|--------------------------------------------------------------|-----------------------------------------------------------------| | Injection | Intramuscular | Requires preparation and injection skill | Reliable; well-established efficacy | Can be intimidating for some; potential for needle stick injuries | | Nasal Spray (Baqsimi) | Nasal | Simple; no mixing or injection required | Easier to administer, especially in emergencies | May not be effective if nasal congestion is present |

Preventive Measures to Avoid Severe Hypoglycemia

Prevention is always better than cure. Individuals with diabetes can take several steps to minimize the risk of severe hypoglycemia:

Consistent Blood Glucose Monitoring

Regularly check blood glucose levels: Use a blood glucose meter or continuous glucose monitor (CGM) to keep track of glucose levels.
Track patterns: Identify times of day or situations that commonly lead to low blood sugar.

Medication Management

Adhere to prescribed dosages: Take medications as prescribed by your healthcare provider.
Coordinate insulin with meals: Properly time insulin injections with meals and snacks.
Adjust dosages as needed: Work with your doctor to adjust medication dosages based on activity levels, diet, and overall health.

Diet and Exercise

Balanced diet: Consume regular, balanced meals and snacks.
Avoid skipping meals: Never skip meals, especially when taking insulin or other diabetes medications.
Plan for exercise: Adjust medication or food intake before, during, and after physical activity.
Carry quick-acting carbohydrates: Always have a source of fast-acting carbohydrates (e.g., glucose tablets, juice) on hand.

Education and Awareness

Educate family and friends: Ensure that family members, friends, and caregivers are aware of the signs of hypoglycemia and how to administer glucagon.
Wear a medical ID: Wear a medical identification bracelet or necklace indicating that you have diabetes.
Regular healthcare check-ups: Attend regular check-ups with your healthcare provider to review and adjust your diabetes management plan.

Preventive Scenario: Sarah, who has type 1 diabetes, always checks her blood sugar before exercising. She knows that exercise can cause her blood sugar to drop, so she reduces her insulin dose on days she plans to work out. She also carries glucose tablets and informs her gym buddy about her condition and what to do if she experiences severe hypoglycemia.

Continuous Glucose Monitoring (CGM) Systems

Continuous Glucose Monitoring (CGM) systems have revolutionized diabetes management by providing real-time glucose readings, trends, and alerts. These systems can be invaluable in preventing severe hypoglycemia.

Benefits of CGM

Real-time glucose monitoring: CGM devices continuously track blood glucose levels, providing up-to-the-minute data.
Trend monitoring: CGM systems display glucose trends, allowing individuals to see whether their blood sugar is rising, falling, or stable.
Alerts and alarms: CGM systems can be set to alert users when their glucose levels are dropping too low or rising too high, allowing for proactive intervention.
Data sharing: Many CGM systems allow users to share their glucose data with healthcare providers and caregivers, enabling better collaboration and support.

Types of CGM Systems

Real-time CGM (rt-CGM): These systems continuously display glucose readings and can provide alerts for low and high glucose levels. Examples include Dexcom G6, Medtronic Guardian Connect, and Abbott FreeStyle Libre 3.
Intermittently Scanned CGM (isCGM): These systems require users to scan a sensor to obtain glucose readings. Abbott FreeStyle Libre 2 is a notable example.

| Feature | Real-Time CGM (rt-CGM) | Intermittently Scanned CGM (isCGM) | |-----------------------|-----------------------------------------------------|--------------------------------------------------------| | Glucose Readings | Continuous, real-time | Requires scanning to obtain readings | | Alerts and Alarms | Customizable high and low glucose alerts | Available on some models (e.g., FreeStyle Libre 2) | | Data Transmission | Automatic data transmission to receiver or smartphone | Manual scanning required for data transmission | | Calibration | May require periodic fingerstick calibration | Typically pre-calibrated | | Cost | Generally more expensive | Generally less expensive |

CGM in Hypoglycemia Prevention

CGM systems help prevent severe hypoglycemia by:

Providing early warning: CGM alerts users when their glucose levels are trending low, allowing them to take preventive action (e.g., consuming a snack) before they become dangerously low.
Identifying patterns: CGM data helps individuals and their healthcare providers identify patterns and trends that contribute to hypoglycemia, enabling them to adjust medication, diet, and activity levels accordingly.
Improving glycemic control: By providing real-time feedback, CGM systems empower individuals to better manage their blood glucose levels and reduce the risk of both hypoglycemia and hyperglycemia.

CGM Example: Emily, who has type 1 diabetes, uses a Dexcom G6 CGM system. One afternoon, she receives a low glucose alert on her smartphone, indicating that her blood sugar is dropping rapidly. Emily checks her blood glucose, which is 75 mg/dL and trending down. She quickly consumes a glucose gel, preventing a potential hypoglycemic episode.

Conclusion

Managing severe hypoglycemia is an essential skill for anyone living with diabetes and their caregivers. Recognizing the symptoms, having a clear emergency plan, understanding glucagon, and implementing preventive measures can significantly reduce the risk and impact of severe hypoglycemic events. By staying informed, prepared, and proactive, individuals with diabetes can live healthier, safer lives.
