Severe Hypoglycemia: Recognizing a Blood Sugar Emergency and What to Do

Severe hypoglycemia, or dangerously low blood sugar, is a critical condition that requires immediate attention. It's a significant risk for people with diabetes, particularly those who use insulin or certain oral medications. Understanding how to recognize the symptoms and knowing how to respond can be life-saving, both for the individual experiencing the episode and for those around them. This article will delve into the signs and symptoms of severe hypoglycemia, outline essential steps for immediate action, and provide strategies for preventing future occurrences.

What is Severe Hypoglycemia?

Hypoglycemia occurs when blood glucose levels drop too low. While mild to moderate hypoglycemia can often be managed with simple actions like consuming fast-acting carbohydrates, severe hypoglycemia is a different beast altogether. It refers to a state where blood glucose levels are so low that the individual experiences cognitive impairment, seizures, loss of consciousness, or other symptoms that require the assistance of another person to treat. Essentially, the person can no longer self-treat the low blood sugar due to the severity of their symptoms.

Why is Severe Hypoglycemia a Blood Sugar Emergency?

The brain relies almost exclusively on glucose for energy. When blood sugar levels plummet, the brain's function is significantly impaired. This can lead to:

Neurological Damage: Prolonged severe hypoglycemia can lead to brain damage.
Seizures: Extremely low blood sugar can trigger seizures.
Loss of Consciousness: Individuals may lose consciousness, creating a risk of injury.
Death: Although rare, severe and untreated hypoglycemia can be fatal.

This emphasizes the importance of prompt recognition and intervention. It's not just about feeling shaky or hungry; it’s about the potential for severe neurological consequences.

Recognizing the Signs and Symptoms of Severe Hypoglycemia

The ability to recognize the warning signs of severe hypoglycemia is paramount. While symptoms vary from person to person, understanding common indicators can prompt immediate action. Remember that symptoms may appear rapidly and escalate quickly, particularly in individuals with impaired awareness of hypoglycemia.

Key Signs and Symptoms:

Here's a detailed breakdown of what to look for:

Cognitive Impairment:
- Confusion or disorientation: The person may appear muddled or struggle to understand simple instructions.
- Difficulty concentrating: They may have trouble focusing on a task or conversation.
- Slurred speech: Their speech may be incoherent or difficult to understand.
- Irrational behavior: Sudden mood swings or uncharacteristic aggression.
Physical Symptoms:
- Seizures: Involuntary muscle contractions or convulsions.
- Loss of consciousness: Unresponsiveness to stimuli.
- Weakness or unsteadiness: Marked difficulty standing or walking.
- Sweating (often profuse): A sudden, unexplained sweat, even in a cool environment.
Neuroglycopenic Symptoms: (Symptoms related to the brain being deprived of glucose)
- Visual disturbances: Blurred vision or double vision.
- Numbness or tingling: Particularly around the mouth or fingers.

Important Note: Some individuals, particularly those who have experienced frequent hypoglycemia, may develop hypoglycemia unawareness, where they no longer experience the early warning signs of low blood sugar. This significantly increases their risk of severe hypoglycemic events.

What to Do in Case of Severe Hypoglycemia: A Step-by-Step Guide

If you suspect someone is experiencing severe hypoglycemia, acting quickly and decisively is vital. Here’s a detailed guide:

Check for Responsiveness:
- Gently shake the person and speak loudly.
- If they do not respond, proceed to the next step.
Administer Glucagon (If Available):
- What is Glucagon? Glucagon is a hormone that raises blood sugar levels by prompting the liver to release stored glucose. It is often prescribed to individuals at risk of severe hypoglycemia.
- How to Administer:
  - Locate the glucagon kit. Make sure you are familiar with its contents and instructions.
  - Inject the glucagon according to the package directions (usually intramuscularly into the thigh, buttock, or arm).
  - If you're unsure, call emergency services and follow their instructions.
Call for Emergency Medical Assistance:
- Dial 911 (or your local emergency number) immediately. Explain the situation and that the person is unresponsive and possibly experiencing severe hypoglycemia.
- Provide the operator with all relevant information, including any known medical conditions (especially diabetes) and any medications the person is taking.
Position the Person Safely:
- If the person is unconscious, place them in the recovery position (on their side) to prevent choking in case of vomiting.
Do NOT Give Food or Drink to an Unconscious Person:
- Attempting to give food or drink to an unconscious person can cause them to choke.
Monitor Breathing and Circulation:
- Check for signs of breathing and a pulse. If necessary, begin CPR (cardiopulmonary resuscitation) if you are trained to do so, until emergency personnel arrive.
Stay with the Person Until Help Arrives:
- Provide comfort and reassurance (if the person regains consciousness) until paramedics take over.
After Glucagon Injection:
- Even if the person regains consciousness after a glucagon injection, they still need to go to the hospital for monitoring and further treatment. Glucagon's effects are temporary.

Key Point: If glucagon is unavailable, call emergency services immediately and follow their instructions. Do not attempt to administer anything by mouth to an unconscious person.

Preventing Future Episodes of Severe Hypoglycemia

Prevention is crucial when it comes to managing severe hypoglycemia. Identifying the underlying causes and implementing appropriate strategies can significantly reduce the risk of future occurrences.

Strategies for Prevention:

Regular Blood Glucose Monitoring:
- Check blood sugar levels frequently, especially before meals, before bed, and after exercise. Continuous glucose monitors (CGMs) can be particularly helpful, as they provide real-time glucose readings and alert the user to trends and potential lows.
Medication Management:
- Work closely with your doctor to adjust medication dosages, especially insulin, as needed. Factors such as changes in activity level, diet, or illness can affect insulin requirements.
- Understand the peak action times of your insulin and plan meals and activities accordingly.
Meal Planning:
- Eat regular, balanced meals and snacks to help stabilize blood sugar levels.
- Be consistent with carbohydrate intake.
Exercise Precautions:
- Check blood sugar levels before, during, and after exercise.
- Carry a fast-acting carbohydrate source (glucose tablets, juice) during exercise.
- Adjust insulin dosages as needed before exercise, in consultation with your doctor.
Alcohol Awareness:
- Be aware that alcohol can lower blood sugar levels, especially when consumed on an empty stomach.
- If you drink alcohol, do so in moderation and with food.
Educate Family and Friends:
- Teach family members, friends, and colleagues how to recognize the signs and symptoms of hypoglycemia and how to administer glucagon.
- Keep a glucagon kit readily accessible and ensure everyone knows where it is located.
Medical Identification:
- Wear a medical ID bracelet or necklace indicating that you have diabetes and are at risk for hypoglycemia. This will alert medical professionals in case of an emergency.
Address Hypoglycemia Unawareness
- Consult your healthcare provider to explore strategies for regaining awareness of low blood sugar. This might include temporarily targeting slightly higher blood glucose levels to allow your body to re-sensitize to the warning signs.

Glucagon: The Lifesaving Medication

Glucagon is a hormone that counteracts the effects of insulin by stimulating the liver to release stored glucose into the bloodstream. It is a crucial medication for treating severe hypoglycemia when a person is unable to take oral carbohydrates.

Types of Glucagon:

Traditionally, glucagon kits required mixing a powder with a liquid before injection. However, newer, user-friendly formulations are now available:

Traditional Glucagon Kit: Contains a vial of glucagon powder and a syringe with diluent.
Nasal Glucagon (Baqsimi): A powder that is sprayed into the nose. No injection required.
Pre-filled Glucagon Syringe (Gvoke HypoPen): An auto-injector pen that delivers a pre-measured dose of glucagon with the push of a button.

Important Note: Nasal glucagon is not effective if the person has nasal congestion.

Who Should Have Glucagon?

Glucagon is typically prescribed for individuals with diabetes who:

Use insulin.
Have a history of severe hypoglycemia.
Have hypoglycemia unawareness.

It is essential that family members, friends, and caregivers know how to administer glucagon properly. Regular training sessions with a healthcare professional are highly recommended.

Living with the Risk of Severe Hypoglycemia

Living with the risk of severe hypoglycemia can be daunting, but with knowledge, proactive management, and a strong support system, it can be effectively minimized.

Build a Strong Relationship with Your Healthcare Team:
- Work closely with your doctor, certified diabetes educator (CDE), and registered dietitian (RD) to develop a comprehensive diabetes management plan that addresses your individual needs and risks.
Stay Informed:
- Keep up-to-date with the latest advancements in diabetes technology and treatments.
Join a Support Group:
- Connecting with other people who have diabetes can provide valuable emotional support and practical advice.
Advocate for Yourself:
- Don't hesitate to speak up and ask questions if you have concerns about your diabetes management plan or the risk of hypoglycemia.

Severe hypoglycemia is a serious medical emergency that requires swift action. Recognizing the signs and symptoms, knowing how to administer glucagon, and understanding preventative strategies are critical for protecting the health and well-being of individuals with diabetes. By empowering ourselves with knowledge and taking proactive steps, we can significantly reduce the risk of severe hypoglycemic events and live healthier, more confident lives.
