What to Do During Severe Hypoglycemia: A Life-Saving Guide

Severe hypoglycemia, or low blood sugar, is a critical condition that can occur in individuals with diabetes. Recognizing the signs, understanding the potential risks, and knowing how to respond quickly and effectively are vital, potentially life-saving skills. This guide provides a comprehensive overview of severe hypoglycemia, including symptoms, immediate actions, and preventive measures.

Understanding Severe Hypoglycemia

Hypoglycemia occurs when blood glucose levels drop too low, typically below 70 mg/dL (3.9 mmol/L). Severe hypoglycemia is characterized by such a significant drop in blood sugar that the individual requires assistance from another person to recover. This could mean the person is unable to treat themselves due to confusion, disorientation, seizures, or loss of consciousness. It's imperative for those managing diabetes, along with their family members, friends, and caregivers, to understand and be prepared for such situations.

Key Risk Factors:

  • Insulin Use: Individuals taking insulin are at a higher risk.
  • Missed Meals: Skipping or delaying meals can lead to low blood sugar.
  • Excessive Exercise: Strenuous physical activity without adequate carbohydrate intake.
  • Alcohol Consumption: Alcohol can interfere with liver's ability to release glucose.
  • Certain Medications: Some oral diabetes medications, particularly sulfonylureas, can also cause hypoglycemia.
  • Kidney or Liver Problems: Impaired kidney or liver function can affect medication metabolism.

Differences between Mild and Severe Hypoglycemia:

| Feature | Mild Hypoglycemia | Severe Hypoglycemia | |-----------------|---------------------------------------------------------|---------------------------------------------------------| | Symptoms | Shakiness, sweating, hunger, dizziness, mild confusion | Seizures, loss of consciousness, severe confusion | | Self-Treatment | Typically self-treated with fast-acting carbohydrates | Requires assistance from another person | | Glucose Level | Usually above 70 mg/dL (3.9 mmol/L) | Significantly below 70 mg/dL (3.9 mmol/L), often undefined | | Level of Danger | Uncomfortable but usually not immediately life-threatening| Potentially life-threatening and requires immediate action |

Recognizing the Signs and Symptoms

The early recognition of symptoms can prevent mild hypoglycemia from escalating to a severe episode. It is essential to know both the common and less obvious indicators.

Common Symptoms:

  • Shakiness: Uncontrollable trembling.
  • Sweating: Unexplained and excessive perspiration.
  • Dizziness: Feeling lightheaded or unsteady.
  • Confusion: Difficulty thinking clearly or concentrating.
  • Irritability: Sudden mood changes or agitation.
  • Hunger: An overwhelming sense of needing to eat.
  • Rapid Heartbeat: Palpitations or a racing pulse.
  • Blurred Vision: Temporary vision problems.

Symptoms Progressing to Severe Hypoglycemia:

  • Disorientation: Unable to understand surroundings or follow instructions.
  • Loss of Coordination: Difficulty walking or performing simple tasks.
  • Seizures: Uncontrolled muscle spasms and convulsions.
  • Loss of Consciousness: Unresponsiveness to stimuli.
  • Inability to Swallow: Makes oral treatment impossible.

It is critical for individuals with diabetes, as well as their close contacts, to learn to recognize these symptoms quickly. Remember that symptoms can vary among individuals and may change over time. Some people may experience hypoglycemia unawareness, meaning they don't experience the typical warning signs until their blood sugar is dangerously low. Regular blood glucose monitoring and discussions with a healthcare provider are vital in such cases.

Immediate Actions During a Severe Hypoglycemic Episode

When severe hypoglycemia strikes, immediate and decisive action is necessary. Follow these steps:

    Assess the Situation:

    • Check for Responsiveness: Attempt to wake the person by calling their name or gently shaking them.
    • Look for Medical Identification: Check for a medical bracelet, necklace, or card indicating diabetes.

    • Do Not Attempt to Give Food or Drink if Unconscious:

    • Trying to force food or liquids into an unconscious person's mouth can cause choking and aspiration.

    • Administer Glucagon:

    • What is Glucagon? Glucagon is a hormone that raises blood sugar levels by stimulating the liver to release stored glucose.

    • How to Administer:
      • Locate the Glucagon Kit: Ensure you know where the glucagon kit is stored at home, work, or school.
      • Follow Instructions: Carefully follow the instructions provided with the glucagon kit. Typically, this involves mixing the glucagon powder with a liquid and injecting it into the thigh, arm, or buttock.
      • Dosage: The standard adult dose is 1 mg. Pediatric doses may vary, so consult the product instructions or a healthcare provider.
    • Important Notes:
      • Glucagon may cause nausea or vomiting.
      • Glucagon is effective for about 90 minutes.

    • Call for Emergency Medical Assistance (911):

    • After administering glucagon, immediately call emergency services. Inform them that the person is experiencing severe hypoglycemia and has received glucagon.

    • Even if the person regains consciousness after glucagon, it's essential to seek professional medical evaluation to prevent a recurrence and identify the cause of the episode.

    • Monitor the Person Closely:

    • Stay with the person and observe their condition.

    • Note the time glucagon was administered and any changes in their responsiveness or symptoms.

    • If the Person Regains Consciousness:

    • Once the person is conscious and able to swallow, give them a fast-acting source of glucose, such as:

      • Glucose Tablets: Follow the package instructions (usually 3-4 tablets).
      • Fruit Juice: About 4 ounces (120 ml).
      • Regular Soda: About 4 ounces (120 ml) (not diet soda).
      • Hard Candies: Several pieces that can be easily chewed.
    • Follow this with a longer-acting carbohydrate snack, such as:
      • Crackers with Peanut Butter
      • A Piece of Fruit
      • A Small Sandwich
    • This will help stabilize blood sugar levels and prevent a relapse.

    • Document the Event:

    • Record the time of the hypoglycemic event, the symptoms experienced, the interventions taken (e.g., glucagon administration), and the person's response.
