How to Handle a Severe Hypoglycemia Emergency: A Guide for Families

Hypoglycemia, or low blood sugar, can be a frightening experience, especially when it becomes severe. For families managing diabetes, knowing how to handle a severe hypoglycemia emergency is crucial. This guide provides clear, actionable steps and information to help you respond effectively and keep your loved one safe. Understanding the signs, having a plan, and knowing how to administer emergency treatments can make all the difference.

Severe hypoglycemia is defined as a condition where a person with diabetes requires assistance from another individual to actively administer treatment, due to impaired consciousness or inability to ingest carbohydrates. The effects can range from confusion and disorientation to seizures or even loss of consciousness, making prompt and decisive action essential.

Why This Guide Matters

  • Empowerment: Equips families with the knowledge to handle a frightening situation confidently.
  • Preparedness: Outlines clear steps to prepare for and manage a severe hypoglycemic episode.
  • Peace of Mind: Reduces anxiety by providing a reliable reference in an emergency.

Understanding Hypoglycemia and Its Severity

Hypoglycemia occurs when the level of glucose (sugar) in the blood drops too low. While mild to moderate episodes can often be managed with quick-acting carbohydrates, severe hypoglycemia requires immediate intervention. Knowing the causes, symptoms, and risk factors can help you identify and respond more effectively.

Common Causes of Hypoglycemia

  • Excessive Insulin: Taking too much insulin or other diabetes medications.
  • Skipped or Delayed Meals: Not eating enough or delaying meals.
  • Increased Physical Activity: Exercising more vigorously than usual without adjusting medication or food intake.
  • Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream.
  • Certain Medications: Some medications, like sulfonylureas, are more likely to cause hypoglycemia.

Recognizing the Symptoms

Identifying hypoglycemia early can prevent it from escalating. Symptoms vary from person to person but commonly include:

  • Mild to Moderate Hypoglycemia:
    • Shakiness or tremors
    • Sweating
    • Rapid heartbeat
    • Anxiety or nervousness
    • Irritability or confusion
    • Dizziness or lightheadedness
    • Hunger
    • Blurred vision
  • Severe Hypoglycemia:
    • Loss of consciousness
    • Seizures
    • Inability to swallow
    • Disorientation
    • Unresponsiveness

Risk Factors for Severe Hypoglycemia

Certain factors increase the likelihood of experiencing a severe hypoglycemic event. Recognizing these can help families take extra precautions.

  • History of Severe Hypoglycemia: Individuals who have previously experienced severe hypoglycemia are at higher risk.
  • Impaired Awareness of Hypoglycemia: Some people lose the ability to recognize the early warning signs of low blood sugar.
  • Tight Glycemic Control: While aiming for tight control, aggressive management increases the risk of hypoglycemia.
  • Long-Standing Diabetes: Individuals with diabetes for a long period may be more prone to hypoglycemic episodes.
  • Kidney or Liver Disease: These conditions can affect how the body processes insulin and glucose.

| Risk Factor | Example | Preventive Measure | | :---------------------------------- | :--------------------------------------------------------------------------------------------- | :------------------------------------------------------------------------------------ | | History of Severe Hypoglycemia | John experienced a seizure due to low blood sugar last year. | More frequent blood glucose monitoring, adjusted medication regimen. | | Impaired Awareness of Hypoglycemia | Mary doesn't feel the usual warning signs (sweating, shakiness) when her blood sugar drops. | Continuous glucose monitoring (CGM), frequent blood glucose checks. | | Tight Glycemic Control | Sarah's A1C target is below 6.5%, requiring precise insulin dosing. | Work closely with a healthcare provider to adjust insulin, flexible insulin dosing. |


Step-by-Step Guide to Handling a Severe Hypoglycemia Emergency

When someone experiences severe hypoglycemia, quick and decisive action is vital. Here’s a step-by-step guide for families:

Step 1: Recognize the Emergency

The first step is recognizing the signs of severe hypoglycemia. These may include unresponsiveness, loss of consciousness, seizures, or an inability to swallow. Prompt recognition is essential to avoid delays in treatment.

Step 2: Do Not Attempt to Feed Orally

Never try to give food or liquids to someone who is unconscious, having a seizure, or unable to swallow. This could cause choking or aspiration, leading to severe complications. The Ultimate Guide To Understanding The Normal Blood Sugar Range

Step 3: Administer Glucagon (If Available)

Glucagon is a hormone that helps raise blood sugar levels by stimulating the liver to release stored glucose. It's available in injectable and nasal spray forms. If you have a glucagon kit and know how to use it:

  1. Locate the Glucagon Kit: Ensure you know where the glucagon kit is stored and that it is not expired.
  2. Prepare the Injection: Follow the instructions that come with the kit. Typically, this involves mixing a powdered form of glucagon with a liquid.
  3. Administer the Injection: Inject the glucagon into the thigh, arm, or buttock.
  4. Turn the Person onto Their Side: Once glucagon is administered, place the person on their side in case of vomiting.
  5. Monitor and Wait: Glucagon usually takes 5-15 minutes to raise blood sugar levels.
  6. If you are using Baqsimi Nasal Glucagon:
    • Locate the Baqsimi nasal glucagon device. Ensure you know where the nasal glucagon device is stored and that it is not expired.
    • Remove Baqsimi from the shrink wrap.
    • Open the cover and firmly press the red plunger all the way in.

Important Notes:

  • Training is Essential: Family members should be trained on how to administer glucagon by a healthcare professional.
  • Check Expiration Dates: Always check the expiration date on the glucagon kit, and replace it before it expires.
  • Storage: Store the kit in a cool, dry place away from direct sunlight.

Step 4: Call for Emergency Medical Assistance

Whether you administer glucagon or not, it's crucial to call for emergency medical assistance immediately. Dial your local emergency number (e.g., 911 in the US, 112 in Europe, or 000 in Australia) and provide the following information:

  • That the person is unconscious or having a seizure.
  • That they are diabetic.
  • That you suspect severe hypoglycemia.
  • Whether or not you administered glucagon.
  • Your location and contact information.

Step 5: Provide Information to Emergency Responders

When emergency responders arrive, provide them with as much information as possible, including:

  • The person's medical history (diabetes type, medications).
  • Any recent blood sugar readings (if available).
  • Whether glucagon was administered and the time of administration.
  • Any other relevant medical conditions or allergies.

Step 6: Post-Emergency Care

After the emergency, consult with the person's healthcare provider to review and adjust the diabetes management plan. This may involve:

  • Adjusting medication dosages
  • Modifying meal plans
  • Reviewing blood glucose monitoring techniques
  • Addressing any underlying causes of the hypoglycemic episode

Debunking Common Myths About Hypoglycemia Management

Several misconceptions can hinder effective hypoglycemia management. Clearing up these myths ensures families are well-informed and prepared to handle emergencies correctly.

Myth 1: Only People with Type 1 Diabetes Experience Severe Hypoglycemia

Reality: While Type 1 diabetes is often associated with a higher risk of hypoglycemia, individuals with Type 2 diabetes who use insulin or certain oral medications (like sulfonylureas) are also susceptible.

Why it Matters: All families managing diabetes, regardless of the type, should understand the risk and know how to respond.

Myth 2: You Can Give an Unconscious Person Sugar Orally

Reality: Giving food or liquids orally to an unconscious person can lead to choking or aspiration. This is dangerous and can cause severe complications.

Why it Matters: It is crucial to administer glucagon or call for emergency assistance immediately instead.

Myth 3: Once Glucagon Is Administered, the Emergency Is Over

Reality: Glucagon raises blood sugar levels, but it's still necessary to call for emergency medical assistance. Glucagon’s effects are temporary, and the underlying cause of the hypoglycemia needs to be addressed.

Why it Matters: Continued monitoring and medical evaluation are essential to prevent a recurrence.

Myth 4: All Glucagon Kits Are the Same

Reality: Glucagon is available in various forms, including injectable kits and nasal sprays (such as Baqsimi). Each has specific instructions for preparation and administration.

Why it Matters: Familiarize yourself with the specific type of glucagon kit you have and follow the instructions carefully.

Myth 5: Severe Hypoglycemia Is Rare and Unlikely to Happen

Reality: Severe hypoglycemia can occur in people with diabetes, especially those with a history of low blood sugar events, impaired hypoglycemia awareness, or tight glycemic control.

Why it Matters: It is essential to be prepared and proactive in managing diabetes to minimize the risk.

Myth 6: If Someone Is Confused But Still Responding, Glucagon Is Not Needed

Reality: Confusion can be a sign of severe hypoglycemia. Even if someone is responsive, administer glucagon if they are unable to take oral carbohydrates due to confusion or disorientation.

Why it Matters: Early intervention can prevent the condition from worsening.
