Severe Hypoglycemia: Emergency Steps Every Family Should Know

Severe hypoglycemia, or dangerously low blood sugar, is a critical condition that demands immediate attention. Especially for families with members who have diabetes, knowing the emergency steps for severe hypoglycemia is crucial for preventing serious complications and ensuring the well-being of loved ones. This guide provides a comprehensive understanding of severe hypoglycemia, how to recognize it, and the actions that should be taken to respond effectively.

Understanding Severe Hypoglycemia

Hypoglycemia occurs when the level of glucose (sugar) in the blood drops too low. For most people with diabetes, this means a blood sugar level below 70 mg/dL (3.9 mmol/L). While mild hypoglycemia can often be managed with quick-acting carbohydrates, severe hypoglycemia represents a more significant threat.

  • Definition: Severe hypoglycemia is defined as a state where the individual's blood glucose level is so low that they require assistance from another person to recover.

  • Causes: Common causes include:

    • Taking too much insulin or other diabetes medications
    • Skipping or delaying meals
    • Unplanned or excessive physical activity
    • Alcohol consumption, especially without food

  • Risks: If untreated, severe hypoglycemia can lead to seizures, loss of consciousness, coma, and, in rare cases, even death. Recognizing the signs and acting quickly is essential.

Recognizing the Signs of Severe Hypoglycemia

Identifying severe hypoglycemia symptoms is the first critical step in providing aid. The symptoms can vary from person to person, but some common signs include:

  • Confusion or Disorientation: The individual may appear confused, have difficulty concentrating, or seem disoriented.
  • Loss of Coordination: Stumbling, clumsiness, or an inability to perform simple tasks.
  • Seizures: Uncontrolled shaking or convulsions.
  • Unconsciousness: Inability to wake up or respond to stimuli.
  • Weakness or Dizziness: Feeling very weak or lightheaded.
  • Sweating: Profuse sweating even in a cool environment.
  • Pale Skin: The skin may appear pale or clammy.
  • Irregular Heartbeat: A rapid or irregular heartbeat can also indicate low blood sugar.

It’s essential for family members and caregivers to familiarize themselves with these signs. If someone with diabetes displays these symptoms, immediate action is necessary.

Emergency Steps to Take During Severe Hypoglycemia

When faced with a case of severe hypoglycemia, quick and decisive action can make all the difference. Here's a step-by-step guide to follow:

  1. Check Responsiveness:

    • Try to wake the person up. Call their name loudly and gently shake them.

  2. Do Not Attempt to Give Food or Drink if Unconscious:

    • This is a critical point. Swallowing can be impaired in an unconscious person, and attempting to feed them can lead to choking.

  3. Administer Glucagon:

    • Glucagon is a hormone that raises blood sugar levels by prompting the liver to release stored glucose. It is available as an injectable or nasal spray and is prescribed by a doctor.
    • How to Use:
      • Injectable Glucagon:
        1. Locate the glucagon emergency kit.
        2. Follow the kit instructions. Typically, this involves mixing the powdered glucagon with the diluent.
        3. Inject the glucagon into the thigh, arm, or buttock. The injection can be given through clothing if necessary.
      • Nasal Glucagon:
        1. Remove the nasal glucagon device from its packaging.
        2. Administer the nasal spray into one nostril. No need to inhale.
    • Who Can Administer: Ideally, all family members and caregivers should be trained by a healthcare professional on how to administer glucagon.
    • Importance: Having a glucagon kit readily available and knowing how to use it can be life-saving.

  4. Call Emergency Services:

    • After administering glucagon, immediately call your local emergency number (e.g., 911 in the US). Provide as much information as possible, including that the person is experiencing severe hypoglycemia, has been given glucagon, and their current condition.
    • Even if the person starts to regain consciousness after the glucagon, it is still crucial to seek professional medical attention to ensure they are fully stabilized.

  5. Monitor the Person Closely:

    • After administering glucagon, monitor the person's breathing and responsiveness.
    • Be prepared to provide CPR if necessary, although this is rare.
    • Note the time the glucagon was administered and any changes in the person’s condition to report to emergency responders.

  6. Once Conscious, Provide a Quick-Acting Carbohydrate:

    • If the person regains consciousness and is able to swallow, give them a source of fast-acting carbohydrates.
    • Examples include:
      • Fruit juice (4 ounces)
      • Regular (non-diet) soda (4 ounces)
      • Glucose tablets (follow package instructions, usually around 3-4 tablets)
      • Hard candies that can be chewed quickly

  7. Follow with a Longer-Acting Carbohydrate and Protein Source:

    • After the initial quick-acting carbohydrate, provide a snack that combines carbohydrates and protein to help stabilize blood sugar levels and prevent a recurrence of hypoglycemia.
    • Examples include:
      • Peanut butter crackers
      • Cheese and crackers
      • A piece of fruit with a handful of nuts

    • Ensure that family members, friends, coworkers, and school staff are aware of the individual's diabetes and know how to recognize and respond to hypoglycemia.
    • Consider having the person wear a medical ID bracelet or necklace that indicates they have diabetes and provides emergency contact information.

Advanced Strategies for Managing Hypoglycemia

For individuals who experience frequent or severe hypoglycemic episodes, additional strategies may be necessary to improve blood sugar control and prevent future occurrences.

  • Continuous Glucose Monitoring (CGM):

    • CGM devices provide real-time blood sugar readings throughout the day and night, alerting the user to trends and potential hypoglycemic or hyperglycemic events.
    • Many CGM systems can be integrated with insulin pumps to automatically adjust insulin delivery based on blood sugar levels, reducing the risk of hypoglycemia.

  • Insulin Pump Therapy:

    • Insulin pumps deliver a continuous, basal rate of insulin throughout the day, as well as bolus doses to cover meals and snacks.
    • Pump therapy allows for more precise insulin dosing and can be programmed to adjust insulin delivery based on exercise, illness, or other factors, helping to prevent hypoglycemia.

  • Adjusting Insulin Doses:

    • Work closely with a healthcare provider to fine-tune insulin doses based on individual needs and patterns.
    • Factors to consider when adjusting insulin doses include:
      • Blood sugar levels before meals and bedtime
      • Carbohydrate intake
      • Exercise habits
      • Stress levels
      • Illness
    • In some cases, a healthcare provider may recommend reducing the basal insulin rate or the bolus insulin dose to prevent hypoglycemia.

  • Hypoglycemia Awareness Training:

    • Some individuals with diabetes may experience a reduced awareness of hypoglycemia, making it difficult to recognize the early warning signs.
    • Hypoglycemia awareness training involves strategies to improve the ability to detect and respond to low blood sugar levels.
    • This may include temporarily raising the target blood sugar range, setting alarms on a CGM device to alert the user to falling blood sugar levels, and practicing mindfulness techniques to increase awareness of physical sensations.

Additional Resources and Support

Living with diabetes can be challenging, but there are numerous resources available to provide support, education, and guidance.

  • American Diabetes Association (ADA): The ADA offers a wealth of information on diabetes management, including resources on hypoglycemia, medication, meal planning, and exercise. They also provide support groups and educational programs.
