Severe Hypoglycemia: Recognizing and Responding to a Diabetes Emergency

Severe hypoglycemia, often referred to as insulin shock or hypo, is a critical and potentially life-threatening complication of diabetes. It occurs when blood glucose levels drop to a dangerously low point, typically below 70 mg/dL (3.9 mmol/L), impairing brain function and requiring immediate intervention. Understanding the causes, symptoms, and emergency treatment of severe hypoglycemia is essential for individuals with diabetes, their families, friends, and caregivers. This comprehensive guide provides detailed information on how to recognize and effectively respond to this diabetes emergency.

What is Hypoglycemia?

Hypoglycemia, in general, refers to low blood sugar. It happens when the level of glucose in the blood drops below what is healthy for your body's needs. For people with diabetes, this often means a blood glucose level below 70 mg/dL. While mild hypoglycemia may cause symptoms like shakiness, sweating, and irritability, severe hypoglycemia is much more serious, leading to confusion, loss of consciousness, seizures, or coma.

Recognizing the Symptoms of Severe Hypoglycemia

The signs and symptoms of severe hypoglycemia can vary from person to person. It's important for those at risk to learn their own individual warning signs. These symptoms often escalate rapidly, making prompt recognition crucial.

Common Symptoms Include:

Loss of Consciousness: This is the most alarming sign, indicating that the brain is not receiving enough glucose.
Seizures: Low blood sugar can trigger abnormal electrical activity in the brain, leading to seizures.
Confusion or Disorientation: Severe hypoglycemia impairs cognitive function, resulting in confusion, difficulty speaking, or irrational behavior.
Inability to Swallow: This makes it impossible to administer oral glucose.
Unresponsiveness: The individual may be unable to respond to questions or commands.
Sweating: Often profuse and cold.
Pale Skin: Due to the body's attempt to conserve blood flow to vital organs.
Rapid Heartbeat: The body's attempt to compensate for low blood sugar.
Difficulty Breathing: Can occur in severe cases.

Example Scenario:

Imagine you're at a restaurant with a friend who has type 1 diabetes. He suddenly becomes disoriented, starts sweating heavily, and is unable to answer simple questions. He then collapses and becomes unresponsive. These are classic signs of severe hypoglycemia, and immediate action is necessary.

Causes of Severe Hypoglycemia in Diabetes

Understanding the common causes of severe hypoglycemia can help prevent future occurrences. Factors that disrupt the balance between insulin, food, and activity can lead to this dangerous condition.

Key Causes Include:

Excessive Insulin Dose: Taking too much insulin relative to food intake or activity level is a primary cause.
Missed or Delayed Meals: Skipping meals or delaying them significantly can deplete glucose stores.
Intense Exercise: Strenuous physical activity can rapidly lower blood glucose levels, especially if insulin dosage is not adjusted accordingly.
Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream, leading to hypoglycemia, particularly when consumed without food.
Kidney or Liver Disease: These conditions can impair the body's ability to regulate glucose levels.
Certain Medications: Some medications, like sulfonylureas (e.g., glipizide, glyburide), are more likely to cause hypoglycemia than others.
Errors in Insulin Administration: Incorrect measurement of insulin or using the wrong type of insulin can lead to severe drops in blood sugar.

| Cause | Explanation | Prevention Strategy | | :--------------------- | :---------------------------------------------------------------------------------- | :--------------------------------------------------------------------------------------- | | Insulin Overdose | Too much insulin for food consumed or activity level. | Carefully measure insulin doses and adjust based on meal size and exercise. | | Missed Meals | Skipping meals depletes glucose reserves. | Never skip meals, especially if taking insulin or oral diabetes medications. | | Intense Exercise | Strenuous activity can rapidly lower blood sugar. | Monitor blood glucose before, during, and after exercise; adjust insulin or carb intake. | | Alcohol Consumption | Alcohol interferes with liver's glucose release. | Consume alcohol with food; monitor blood glucose levels. | | Kidney/Liver Disease | Impairs glucose regulation. | Work closely with your doctor to manage these conditions. |

Responding to a Severe Hypoglycemia Emergency: Step-by-Step Guide

When someone experiences severe hypoglycemia, time is of the essence. Follow these steps to provide immediate and effective assistance:

Step 1: Assess the Situation and Ensure Safety

Check for Responsiveness: Gently shake the person and ask if they are okay. If they do not respond, it is a medical emergency.
Ensure a Safe Environment: If possible, move the person away from potential hazards, such as traffic or sharp objects.

Step 2: Call for Emergency Medical Assistance

Call 911 (or your local emergency number) Immediately: Provide the dispatcher with accurate information, including the person's condition, location, and that they are experiencing a possible diabetic emergency.
Do not hang up until instructed to do so.

Step 3: Administer Glucagon (If Available)

Locate the Glucagon Kit: People with diabetes who are at risk of severe hypoglycemia should have a glucagon emergency kit readily available and their caregivers should know how to use it.
Prepare and Administer Glucagon: Follow the instructions on the glucagon kit carefully. Typically, this involves mixing the glucagon powder with the provided liquid and injecting it into the muscle (usually the thigh or arm). Note: Glucagon is prescribed by a doctor. You must have a prescription and a glucagon kit to use it. Glucagon raises blood sugar levels by prompting the liver to release stored glucose into the bloodstream.

Step 4: If Glucagon is Not Available or You are Not Trained to Use It

Do NOT Give Anything by Mouth: Because the person is unconscious or unable to swallow, attempting to give food or liquid could cause choking.
Position the Person on Their Side: This helps to prevent choking if vomiting occurs.

Step 5: Monitor the Person

Observe for Changes in Condition: Monitor the person's breathing, pulse, and level of consciousness until emergency medical services arrive.
Be Prepared to Provide Information: When paramedics arrive, provide them with any relevant medical history, medications, and the circumstances leading to the emergency.

Example Scenario (Continued):

Returning to our restaurant example, you remember that your friend has a glucagon kit in his bag. You quickly retrieve it and follow the instructions to administer the injection into his thigh. While waiting for the ambulance, you position him on his side to prevent choking and continuously monitor his breathing. When the paramedics arrive, you provide them with all the relevant information, including the fact that he has diabetes, the symptoms he experienced, and that you administered glucagon.

After the Emergency: Preventing Future Occurrences

After a severe hypoglycemic episode, it is crucial to work with a healthcare team to identify the underlying causes and implement strategies to prevent future occurrences.

Key Steps to Take:

Review Insulin Dosage and Timing: Work with a doctor or certified diabetes educator (CDE) to evaluate the insulin regimen and make any necessary adjustments.
Assess Meal Planning: Ensure consistent meal timing and carbohydrate intake to match insulin doses. A registered dietitian can provide guidance.
Monitor Blood Glucose Levels More Frequently: Increased monitoring can help identify patterns and trends that contribute to hypoglycemia.
Adjust Exercise Routine: Discuss exercise plans with a doctor or CDE to adjust insulin and carbohydrate intake accordingly.
Educate Family and Friends: Ensure that family members, friends, and caregivers know how to recognize the symptoms of hypoglycemia and how to administer glucagon.
Wear a Medical Identification: A medical ID bracelet or necklace can alert others to the person's diabetes in case of an emergency.
Carry a Fast-Acting Source of Glucose: Always have a readily available source of glucose, such as glucose tablets, juice, or hard candies, to treat mild hypoglycemia promptly.

Tips for Preventing Hypoglycemia:

Check blood glucose levels regularly, especially before meals, before exercise, and at bedtime.
Never skip meals, and try to eat at consistent times each day.
Adjust insulin doses based on food intake and activity level, as directed by your healthcare team.
Be aware of how alcohol affects blood glucose levels and consume it in moderation and with food.
Communicate openly with your healthcare team about any episodes of hypoglycemia or concerns about blood glucose control.

Glucagon: The Lifesaving Medication for Severe Hypoglycemia

Glucagon is a hormone that raises blood glucose levels by stimulating the liver to release stored glucose into the bloodstream. It is a critical medication for treating severe hypoglycemia, particularly when the person is unable to take oral glucose due to unconsciousness or seizures.

Types of Glucagon Kits:

Traditional Glucagon Emergency Kit: This includes a vial of powdered glucagon and a syringe filled with sterile diluent. The liquid must be mixed with the powder before injection.
Nasal Glucagon (Baqsimi): This is a powder that is administered directly into the nose, without the need for an injection.
Pre-filled Syringe Glucagon (Gvoke HypoPen): A pre-mixed, ready-to-inject glucagon that is administered via an auto-injector pen.

Important Considerations:

Prescription Required: Glucagon is a prescription medication and must be prescribed by a doctor.
Training: Caregivers should be trained on how to properly administer glucagon.
Expiration Date: Check the expiration date of the glucagon kit regularly and replace it before it expires.
Side Effects: Common side effects of glucagon include nausea and vomiting.

Legal and Ethical Considerations

Providing assistance to someone experiencing severe hypoglycemia involves certain legal and ethical considerations.

Good Samaritan Laws: These laws protect individuals who provide assistance to someone in distress from liability, as long as they act in good faith and without gross negligence.
Informed Consent: Ideally, a person with diabetes should provide consent for others to administer glucagon or provide assistance in case of a hypoglycemic emergency. However, in cases of unconsciousness or incapacitation, implied consent is generally assumed.
Privacy: Respect the person's privacy and avoid disclosing their medical information to others without their consent.

It is essential to familiarize yourself with the specific laws and regulations in your jurisdiction regarding emergency medical assistance.

Conclusion
