A Guide for Persons with Diabetes: Surviving Severe Hypoglycemia

Diabetes management involves a careful balancing act, ensuring blood glucose levels remain within a target range. While high blood glucose (hyperglycemia) is a common concern, dangerously low blood glucose, known as severe hypoglycemia, presents an immediate and potentially life-threatening risk. This guide provides essential information for people with diabetes, their families, and caregivers on how to recognize, treat, and prevent severe hypoglycemia. Understanding and acting swiftly in these situations can be crucial for survival.

Understanding Hypoglycemia

Hypoglycemia, often referred to as low blood sugar, occurs when glucose levels in the blood drop below normal. For people with diabetes, this generally means a blood sugar level of less than 70 mg/dL (3.9 mmol/L), but this target can vary depending on individual circumstances and healthcare provider recommendations. Severe hypoglycemia is a more critical situation where the individual requires assistance from another person to recover. This usually happens when the blood sugar drops so low that the brain isn’t getting enough glucose to function properly.

Causes of Hypoglycemia:

Several factors can contribute to hypoglycemia in individuals with diabetes:

Excessive insulin dose: Taking too much insulin, either intentionally or due to a miscalculation, is a primary cause.
Skipping meals or delayed eating: Not eating enough, or waiting too long between meals, can lead to a drop in blood glucose.
Increased physical activity: Exercise can increase insulin sensitivity and glucose utilization, leading to hypoglycemia if not managed properly.
Alcohol consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream, particularly when consumed on an empty stomach.
Certain medications: Some oral diabetes medications, such as sulfonylureas, can also cause hypoglycemia.
Kidney or liver problems: Impaired kidney or liver function can affect the metabolism of insulin and glucose, increasing the risk of hypoglycemia.

Recognizing the Symptoms of Severe Hypoglycemia

Being able to recognize the symptoms of hypoglycemia is critical for prompt treatment. While the symptoms of mild to moderate hypoglycemia can often be self-treated, severe hypoglycemia requires immediate assistance. The symptoms can vary from person to person, but common signs include:

Confusion: Difficulty thinking clearly or understanding instructions.
Disorientation: Feeling lost or unaware of your surroundings.
Loss of consciousness: Passing out or being unresponsive.
Seizures: Uncontrolled muscle contractions.
Combativeness or irrational behavior: Acting aggressively or unusually.
Inability to swallow: Making it difficult to administer oral glucose.

It's crucial for family members and caregivers to be aware of these signs so they can recognize when someone is experiencing severe hypoglycemia, especially if the individual with diabetes is unable to communicate.

Immediate Treatment for Severe Hypoglycemia

The primary goal in treating severe hypoglycemia is to raise blood glucose levels as quickly as possible. Since the individual is unable to self-treat, external assistance is essential.

Call for Emergency Medical Assistance: If the person is unconscious, having a seizure, or if you're unsure about how to proceed, immediately call emergency services (911 in the US, 112 in Europe, 000 in Australia).
Administer Glucagon: Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream. It's available as an injectable medication or a nasal spray. Every person with diabetes at risk of severe hypoglycemia should have a glucagon kit or nasal spray on hand and caregivers/family members should know how to use it.
- Injectable Glucagon: Follow the instructions in the glucagon kit. Typically, you'll mix the powder with the liquid, then inject it into the thigh, arm, or buttock.
- Nasal Glucagon: Follow the instructions provided with the product. The nasal spray is administered directly into one nostril, without the need to inhale.
Here’s a table summarizing the key differences:
| Feature | Injectable Glucagon | Nasal Glucagon | |------------------|--------------------------------------------------------|-----------------------------------------------------| | Administration | Injection (intramuscular or subcutaneous) | Nasal Spray | | Preparation | Requires mixing | Ready to use | | Ease of Use | Slightly more complex due to mixing | Simpler, especially for non-medical personnel | | Absorption | Direct absorption into the bloodstream | Absorption through the nasal mucosa |
Turn the Person on Their Side: After administering glucagon, turn the person onto their side in the recovery position. This helps prevent choking if they vomit.
Monitor and Wait: It may take 10-15 minutes for glucagon to raise blood glucose levels. If there is no improvement after this time, and emergency services haven’t arrived yet, contact medical professionals for further guidance. How To Create The Perfect Diabetic Diet Plan To Keep Your A1C In Range
Provide Sustained Glucose Intake (Once Conscious): Once the person regains consciousness and is able to swallow, give them a fast-acting source of glucose, such as fruit juice, glucose tablets, or regular soda. Follow this with a longer-acting carbohydrate source like crackers or a sandwich to stabilize blood glucose levels.

Important Considerations:

Do NOT attempt to give food or liquids to an unconscious person, as this could cause choking.
Glucagon is effective even if the person has recently eaten, although the response might be slightly delayed.
Glucagon may cause nausea or vomiting in some individuals.
Once recovered, encourage the person to check their blood glucose levels frequently over the next few hours to ensure they remain within the target range.
Document the episode and any actions taken, and share this information with the person's healthcare provider.

Preventing Future Episodes of Severe Hypoglycemia

Prevention is always better than cure. By understanding the causes and risk factors for hypoglycemia, individuals with diabetes can take steps to reduce their chances of experiencing a severe episode. Here are some key strategies:

Regular Blood Glucose Monitoring: Frequent monitoring of blood glucose levels, especially before meals, before and after exercise, and at bedtime, can help identify trends and potential problems. Continuous Glucose Monitors (CGMs) can be particularly useful for detecting glucose fluctuations and alerting the user to impending lows.
Careful Insulin Management: Work closely with your healthcare provider to adjust your insulin dose based on your diet, activity level, and other factors. Be precise when measuring insulin doses, and double-check your work.
Meal Planning and Timing: Eat regular meals and snacks, and avoid skipping meals or delaying eating. Consult a registered dietitian or diabetes educator to develop a meal plan that meets your individual needs and helps you maintain stable blood glucose levels.
Adjusting Insulin for Exercise: If you are physically active, adjust your insulin dose or increase your carbohydrate intake before, during, or after exercise, as needed. Monitor your blood glucose levels more frequently when you are exercising.
Alcohol Moderation: If you choose to drink alcohol, do so in moderation, and always consume it with food. Be aware that alcohol can lower blood glucose levels, especially when consumed on an empty stomach.
Medication Awareness: Understand how your medications can affect your blood glucose levels, and discuss any concerns with your healthcare provider. Some medications, such as beta-blockers, can mask the symptoms of hypoglycemia.
Diabetes Education: Participate in a comprehensive diabetes education program to learn more about diabetes management, including how to prevent and treat hypoglycemia.
Wear a Medical Identification: Wear a medical ID bracelet or necklace indicating that you have diabetes and are at risk of hypoglycemia. This can alert first responders to your condition in an emergency.
Educate Family and Caregivers: Ensure that your family members, friends, and caregivers know how to recognize the symptoms of hypoglycemia and how to administer glucagon.

Practical Example: Responding to Severe Hypoglycemia in a Real-Life Scenario

Let's consider a scenario: Sarah, a 65-year-old with type 1 diabetes, is found unconscious in her living room by her daughter, Emily. Emily knows her mother has diabetes and suspects hypoglycemia. Here's how Emily should respond:

Assessment: Emily first checks if Sarah is responsive. Sarah does not respond to verbal or physical stimulation.
Emergency Call: Emily immediately calls 911, providing the dispatcher with her address, Sarah's condition (unconsciousness), and that she has diabetes.
Glucagon Administration: Emily retrieves Sarah’s glucagon kit, which is always kept in a specific location in the kitchen. She follows the instructions to mix and administer the glucagon injection into Sarah's thigh.
Recovery Position: Emily carefully turns Sarah onto her side in the recovery position to prevent choking.
Monitoring: Emily monitors Sarah’s breathing and waits for emergency services to arrive.
Post-Recovery Actions (if applicable): Once Sarah regains consciousness and is able to swallow (upon paramedics' advice), Emily provides her with juice and a granola bar to stabilize her blood sugar.

The Role of Technology in Managing Hypoglycemia

Technology has significantly improved the management of diabetes, offering tools to prevent and mitigate hypoglycemia.

Continuous Glucose Monitoring (CGM): CGMs track glucose levels in real-time, alerting users to trends and potential lows before they become severe. Alarms can be set to trigger when glucose drops below a specific threshold.
Insulin Pumps: Insulin pumps deliver a steady, controlled dose of insulin, reducing the risk of significant blood sugar fluctuations. When integrated with a CGM, advanced pumps can even suspend insulin delivery when glucose levels are predicted to drop too low. These are often referred to as closed-loop systems or artificial pancreas systems.
Mobile Apps: Many diabetes management apps allow users to log their blood glucose levels, track their food intake and activity, and calculate insulin doses. These apps can provide valuable insights into patterns and help identify potential triggers for hypoglycemia.

Here's a table comparing the advantages of using a CGM versus traditional blood glucose monitoring:

| Feature | Continuous Glucose Monitoring (CGM) | Traditional Blood Glucose Monitoring (BGM) | |-----------------------------|-------------------------------------------------------------------|-------------------------------------------------------------| | Glucose Readings | Real-time, continuous readings | Discrete readings at specific points in time | | Trend Information | Provides trend arrows indicating the direction and rate of change | Does not provide information on glucose trends | | Alarms & Alerts | Alerts for high and low glucose levels | Requires manual testing to identify highs and lows | | Data Accessibility | Data accessible on devices and easily shared with healthcare team | Requires manual logging and data interpretation | | Convenience | Minimizes fingersticks | Requires multiple fingersticks daily | A1C Test Vs Cgm Which Is Better For Managing Your Diabetes

Conclusion

Surviving severe hypoglycemia requires a proactive approach that involves education, vigilance, and preparedness. Individuals with diabetes, their families, and caregivers must understand the causes, symptoms, and treatment of severe hypoglycemia. By implementing preventive strategies, having glucagon readily available, and knowing how to respond in an emergency, it's possible to significantly reduce the risk and impact of severe hypoglycemia. Continuous communication with healthcare professionals and ongoing education are also essential for optimizing diabetes management and ensuring a safe and healthy life.
