Severe Hypoglycemia: What to Do in a Low Blood Sugar Emergency

Hypoglycemia, often referred to as low blood sugar, occurs when the level of glucose (sugar) in your blood drops too low. While mild hypoglycemia can often be managed with quick snacks or sugary drinks, severe hypoglycemia is a medical emergency requiring immediate intervention. This condition can lead to serious consequences, including seizures, loss of consciousness, and even death. This article provides a comprehensive guide on recognizing, preventing, and responding to severe hypoglycemia, ensuring you're well-prepared to handle such an emergency.

Understanding Hypoglycemia

Hypoglycemia is typically defined as a blood sugar level below 70 mg/dL (3.9 mmol/L). It's a common complication for people with diabetes, particularly those who use insulin or certain oral medications that stimulate insulin production. Understanding the underlying causes and risk factors is essential for effective management.

Causes of Hypoglycemia

Several factors can cause blood sugar to drop too low, including:

Excessive Insulin: Taking too much insulin relative to food intake is a primary cause.
Missed or Delayed Meals: Skipping meals or eating less than usual can lead to hypoglycemia.
Increased Physical Activity: Exercise increases glucose consumption, and if not properly managed with additional food intake, it can cause a drop in blood sugar.
Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream, especially when consumed on an empty stomach.
Certain Medications: Besides insulin, some oral diabetes medications like sulfonylureas (e.g., glipizide, glyburide) can cause hypoglycemia.
Kidney or Liver Problems: Impaired kidney or liver function can affect glucose metabolism and drug clearance.
Hormone Deficiencies: Certain hormonal disorders (e.g., adrenal insufficiency) can contribute to hypoglycemia.

Risk Factors for Severe Hypoglycemia

Several factors can increase the risk of experiencing severe hypoglycemia:

Long-standing Diabetes: Individuals with long-term diabetes may have reduced awareness of hypoglycemia symptoms.
Intensive Insulin Therapy: Aiming for very tight blood sugar control can increase the risk of hypoglycemia.
Hypoglycemia Unawareness: This condition occurs when individuals no longer experience the early warning signs of low blood sugar, making it harder to prevent severe episodes.
Cognitive Impairment: Conditions affecting cognitive function can make it difficult to manage diabetes effectively.
Elderly Individuals: Older adults may have impaired kidney or liver function, increasing their vulnerability to hypoglycemia.

| Risk Factor | Explanation | | --------------------------- | -------------------------------------------------------------------------- | | Long-Standing Diabetes | Reduced awareness of hypoglycemia symptoms | | Intensive Insulin Therapy | Aiming for very tight blood sugar control | | Hypoglycemia Unawareness | Inability to recognize early warning signs of low blood sugar | | Cognitive Impairment | Difficulty managing diabetes effectively | | Elderly Individuals | Impaired kidney or liver function increasing vulnerability to hypoglycemia |

Recognizing Severe Hypoglycemia

Recognizing the signs and symptoms of severe hypoglycemia is critical for timely intervention. The symptoms can vary from person to person, but typically include the following:

Loss of Consciousness: This is a hallmark sign of severe hypoglycemia.
Seizures: Uncontrolled muscle spasms due to the brain being deprived of glucose.
Confusion or Disorientation: Marked cognitive impairment making it difficult to think clearly.
Inability to Swallow: Difficulty or inability to swallow making it impossible to take oral medication or food.
Unresponsiveness: The person may be unable to respond to questions or commands.

It is also important to note milder symptoms of hypoglycemia that may precede severe episodes, including:

Shakiness
Sweating
Dizziness
Hunger
Irritability or Anxiety
Confusion
Blurred Vision

If these milder symptoms are not addressed promptly, they can progress to severe hypoglycemia.

What to Do During a Severe Hypoglycemia Emergency

When someone experiences severe hypoglycemia, it is crucial to act quickly and decisively. Here’s a step-by-step guide:

Assess the Situation:
- Check for responsiveness: Try to rouse the person by calling their name and gently shaking them.
- Look for medical identification: Check for a medical ID bracelet or necklace indicating they have diabetes.
- If the person is conscious and able to swallow, proceed to step 2. If they are unconscious, unable to swallow, or having seizures, move directly to step 3 and call for emergency medical assistance.
- Administer Fast-Acting Carbohydrates (If Conscious):
- Give a source of fast-acting carbohydrates:
  - Glucose Tablets: Provide 3-4 glucose tablets (check the product label for carbohydrate content).
  - Glucose Gel: Administer a single serving of glucose gel according to the product instructions.
  - Sugary Liquid: If glucose tablets or gel are not available, give a sugary liquid like fruit juice or regular (non-diet) soda. Avoid giving diet drinks as they won't raise blood sugar. About 4 ounces (120 ml) is usually sufficient.
- Avoid Fatty Foods: Do not give foods high in fat, such as chocolate or peanut butter, as they can slow down glucose absorption.
- Monitor: Check blood sugar again after 15 minutes. If it remains low (below 70 mg/dL) or if symptoms persist, repeat the carbohydrate administration.
- Administer Glucagon (If Unconscious):
- Use a Glucagon Emergency Kit: Glucagon is a hormone that raises blood sugar levels quickly. If the person is unconscious or unable to swallow, someone trained to administer glucagon should do so.
- How to Administer:
  - Follow the instructions in the glucagon emergency kit carefully. Typically, the kit contains a syringe with sterile water and a vial of powdered glucagon.
  - Inject the water into the vial, mix gently, and then withdraw the solution back into the syringe.
  - Inject the glucagon intramuscularly into the upper arm, thigh, or buttock.
  - Turn the person onto their side to prevent choking if they vomit.
- Call for Emergency Medical Assistance: Even after administering glucagon, it is essential to call emergency services immediately.
- Call Emergency Services (911):

- If the person is unconscious, having seizures, or does not respond to glucagon within 15 minutes, call 911 (or your local emergency number) immediately.
- Inform the emergency responders that the person has diabetes and is experiencing severe hypoglycemia.
- After Recovery:
- Once the person regains consciousness and can eat, give them a longer-acting source of carbohydrates, such as a sandwich or crackers with peanut butter, to help stabilize blood sugar levels.
- Encourage them to see their healthcare provider as soon as possible to review their diabetes management plan and prevent future episodes of severe hypoglycemia.

| Step | Action | Rationale | | --------------------------------------- | ------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------- | | Assess the Situation | Check responsiveness and look for medical ID. | Determines the level of intervention required and confirms the person has diabetes. | | Administer Fast-Acting Carbohydrates | Glucose tablets, gel, or sugary liquid if conscious and able to swallow. | Raises blood sugar levels quickly. | | Administer Glucagon | Glucagon injection if unconscious and someone is trained to administer it. | Stimulates the liver to release stored glucose into the bloodstream. | | Call Emergency Services (911) | Call for emergency medical assistance, especially if the person is unconscious or unresponsive. | Ensures professional medical care is provided promptly. | | After Recovery | Give a longer-acting carbohydrate source and encourage a visit to their healthcare provider. | Helps stabilize blood sugar levels and prevents future episodes. |

Using Glucagon Effectively

Glucagon is a life-saving medication for individuals with diabetes at risk of severe hypoglycemia. It is crucial for family members, caregivers, and close contacts to be trained on how to administer glucagon in an emergency.

Types of Glucagon Kits

Several glucagon products are available, including:

Traditional Glucagon Emergency Kit: This kit includes a vial of powdered glucagon and a syringe with sterile water that needs to be mixed before injection.
Pre-filled Syringe: These kits contain a pre-filled syringe with liquid glucagon, making them easier to administer in an emergency.
Nasal Glucagon (Baqsimi): This is an inhalable form of glucagon that is administered through the nose, which can be easier to use than an injection, particularly if the person is agitated or uncooperative.

How to Use Glucagon

Read the Instructions: Always read the instructions in the glucagon kit before an emergency occurs.
Check Expiration Date: Ensure the glucagon is not expired.
Preparation:
- For traditional kits: Inject the sterile water into the vial of powdered glucagon. Gently roll the vial to mix the solution until it is clear. Do not shake it vigorously, as this can create air bubbles.
- Withdraw the mixed glucagon solution back into the syringe.
Injection Site: Inject the glucagon into the upper arm, thigh, or buttock.
Administration:
- Pinch the skin at the injection site.
- Insert the needle at a 90-degree angle into the muscle.
- Push the plunger to inject the glucagon.
- Remove the needle and apply gentle pressure to the injection site.
Nasal Glucagon (Baqsimi):
- Remove the device from the packaging.
- Hold the device between your fingers and thumb. Do not prime or test the device.
- Insert the nozzle into one nostril and press the plunger firmly all the way in. The dose is complete when the line turns red.
After Administration:
- Call for emergency medical assistance immediately.
- Monitor the person closely. They should regain consciousness within 15-20 minutes. If they do not respond, continue to follow emergency protocols.
- Once conscious, give them a longer-acting carbohydrate source to stabilize blood sugar.

| Type of Glucagon Kit | Administration Method | Advantages | Disadvantages | | -------------------------- | ------------------------------------------------------------------------ | ----------------------------------------------------------------------------- | --------------------------------------------------------------------------------- | | Traditional Kit | Mixing required, intramuscular injection | Lower cost, widely available | Requires multiple steps, potential for error | | Pre-filled Syringe | Ready to inject, intramuscular injection | Easier to use, less potential for error | May be more expensive | | Nasal Glucagon (Baqsimi) | Nasal spray | Easy to administer, no injection required, user-friendly | May not be effective if nasal passages are congested, newer and may not be widespread availability |
