Severe Hypoglycemia: Recognizing the Signs and What to Do Immediately

Severe hypoglycemia, or critically low blood sugar, is a dangerous condition that requires immediate intervention. Understanding the signs and symptoms of severe hypoglycemia and knowing the appropriate actions to take can be life-saving, especially for individuals with diabetes or related conditions. This article provides a comprehensive guide to recognizing severe hypoglycemia and what to do in such emergencies.

Understanding Hypoglycemia and Its Severity

Hypoglycemia occurs when blood glucose levels drop too low, usually below 70 mg/dL (3.9 mmol/L). This can happen for various reasons, including:

• Taking too much insulin
• Skipping meals or not eating enough carbohydrates
• Increased physical activity without adjusting medication or food intake
• Drinking alcohol, especially without eating
• Certain medical conditions or medications

While mild hypoglycemia can often be managed independently, severe hypoglycemia requires assistance from another person because the individual experiencing it may be unable to help themselves.

Recognizing the Signs and Symptoms of Severe Hypoglycemia

The symptoms of severe hypoglycemia are more pronounced than those of mild hypoglycemia. Prompt recognition is critical. The key signs and symptoms include:

• Loss of Consciousness: This is one of the most alarming signs and requires immediate action.
• Seizures: Uncontrolled shaking or jerking of the body.
• Confusion or Disorientation: Severe difficulty in thinking clearly or understanding surroundings.
• Inability to Swallow: Difficulty or inability to take fluids or food orally.
• Unresponsiveness: The person does not respond to stimuli or attempts to communicate.
• Extreme Weakness: Too weak to stand or move.

It’s crucial to note that symptoms can vary from person to person. Familiarity with an individual's usual hypoglycemia symptoms can aid in quicker recognition.

Immediate Actions to Take When Someone is Experiencing Severe Hypoglycemia

When you suspect someone is experiencing severe hypoglycemia, follow these steps immediately:

1. Do NOT Give Food or Drink if Unconscious: Never attempt to give food or drink to an unconscious person as this could cause choking.
2. Administer Glucagon (If Available): If a glucagon kit is available and you know how to use it, inject the person with glucagon according to the kit's instructions. Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream.
3. Call for Emergency Medical Assistance: Immediately call emergency services (911 in the US, 999 in the UK, 112 in Europe) or your local emergency number. Provide clear information about the person’s condition, including that they are unconscious or having a seizure due to low blood sugar.
4. Turn the Person on Their Side: If the person is unconscious, place them in the recovery position (on their side) to prevent choking, especially if they vomit.
5. Stay with the Person: Remain with the person until medical help arrives, monitoring their breathing and pulse.

After the Emergency: What to Do Next

Once the immediate danger has passed and medical assistance has arrived, the following steps should be considered:

1. Medical Evaluation: Ensure the person receives a thorough medical evaluation to determine the cause of the severe hypoglycemia and to adjust their treatment plan if necessary.
2. Review Medication and Meal Plans: Work with healthcare providers to review the person's medications (especially insulin) and meal plans to prevent future episodes.
3. Education: Reinforce education about diabetes management, including recognizing and treating hypoglycemia. Ensure the individual and their caregivers know how to use glucagon properly.
4. Personalized Action Plan: Create a personalized action plan for managing hypoglycemia, including specific instructions and emergency contacts.
5. Consider Continuous Glucose Monitoring (CGM): Discuss the possibility of using a CGM system, which can provide real-time glucose readings and alert the individual to potential low blood sugar levels.

The Role of Glucagon in Treating Severe Hypoglycemia

Glucagon is a crucial medication for treating severe hypoglycemia. It is a hormone that works by stimulating the liver to release stored glucose into the bloodstream, rapidly raising blood sugar levels. It comes in injectable and nasal spray forms.

How to Administer Glucagon Injection:

1. Prepare the Glucagon Kit: Follow the instructions in the glucagon kit carefully. Typically, this involves mixing the powdered glucagon with the provided diluent.
2. Administer the Injection: Inject the glucagon into the muscle (e.g., upper arm, thigh, or buttocks).
3. Wait and Monitor: It usually takes 10-15 minutes for the glucagon to work. If the person does not regain consciousness within that time, continue to wait for medical assistance.

How to Administer Nasal Glucagon:

1. Prepare the Device: Follow the specific instructions that come with the nasal glucagon device.
2. Administer the Dose: Insert the tip of the device into one nostril and press the plunger to deliver the dose. There is no need to inhale or prime the device.
3. Wait and Monitor: Similarly to injectable glucagon, wait and monitor for improvement while awaiting medical assistance.

Preventing Severe Hypoglycemia

Prevention is always better than cure. Several strategies can help minimize the risk of severe hypoglycemia:

• Regular Glucose Monitoring: Regularly checking blood glucose levels, especially before meals, before bed, and after exercise, is critical.
• Consistent Meal Schedules: Maintaining regular meal schedules and avoiding skipping meals can help stabilize blood glucose levels.
• Adjusting Medication: Work closely with healthcare providers to adjust medication dosages, particularly insulin, based on blood glucose readings and lifestyle factors.
• Carbohydrate Counting: Learning how to accurately count carbohydrates can help with precise insulin dosing.
• Exercise Precautions: Taking extra precautions before, during, and after exercise, such as checking blood glucose and having a snack available, can help prevent hypoglycemia.
• Alcohol Consumption: Limiting alcohol consumption and always eating when drinking alcohol can reduce the risk of low blood sugar.
• Education and Awareness: Staying informed about diabetes management and recognizing the signs and symptoms of hypoglycemia are vital.

The Importance of Medical Identification

Wearing a medical identification bracelet or carrying a medical ID card that indicates a person has diabetes and may experience hypoglycemia can be crucial in an emergency situation. This information alerts first responders and bystanders to the potential cause of unconsciousness or disorientation.

Recognizing Risk Factors for Severe Hypoglycemia

Certain factors can increase the risk of severe hypoglycemia. Being aware of these risk factors can help individuals and their caregivers take extra precautions. These factors include:

• History of Severe Hypoglycemia: Individuals who have previously experienced severe hypoglycemia are at higher risk for future episodes.
• Long-Standing Diabetes: People with long-standing diabetes may have decreased awareness of hypoglycemia.
• Kidney Disease: Kidney disease can affect insulin metabolism and increase the risk of hypoglycemia.
• Certain Medications: Some medications, such as sulfonylureas, can increase insulin secretion and raise the risk of low blood sugar.
• Cognitive Impairment: Individuals with cognitive impairment may have difficulty recognizing or responding to the symptoms of hypoglycemia.

Using Continuous Glucose Monitoring (CGM) Systems

Continuous Glucose Monitoring (CGM) systems have become increasingly popular and effective in managing diabetes and preventing hypoglycemia. These devices continuously monitor glucose levels through a small sensor inserted under the skin and transmit readings to a receiver or smartphone.

Benefits of CGM:

• Real-Time Glucose Readings: CGM provides real-time glucose readings, allowing individuals to see how their blood sugar is changing throughout the day and night.
• Trend Arrows: CGM displays trend arrows that indicate the direction and rate of glucose change, allowing individuals to anticipate and prevent low blood sugar.
• Alerts and Alarms: CGM can be programmed to alert the individual when glucose levels are trending low or have reached a pre-set low threshold.
• Data Tracking: CGM data can be used to identify patterns and trends, helping individuals and healthcare providers optimize their diabetes management plan.

Example Scenario

To further illustrate the concepts, consider this hypothetical situation:

Sarah, a 45-year-old with type 1 diabetes, experiences severe hypoglycemia while at home alone. Her blood sugar drops rapidly due to an accidental overdose of insulin. She becomes confused and eventually loses consciousness. Fortunately, her neighbor, John, knows that Sarah has diabetes because she wears a medical ID bracelet. John immediately recognizes the signs of severe hypoglycemia, calls emergency services, and administers glucagon from Sarah's kit after finding it in the refrigerator door. Because of John’s quick actions, paramedics arrive promptly and provide further medical care, stabilizing Sarah.

Key Takeaways

Recognizing and responding to severe hypoglycemia quickly can prevent serious complications. Remember these crucial points:

• Be aware of the signs and symptoms of severe hypoglycemia.
• Never give food or drink to an unconscious person.
• Administer glucagon if available and you know how to use it.
• Call emergency services immediately.
• Stay with the person and monitor their condition until help arrives.
• Preventing severe hypoglycemia through careful diabetes management is vital.
