What to Do When Your Blood Sugar is Dangerously Low (Hypoglycemia)

A sudden drop in blood sugar, clinically known as hypoglycemia, can be a disorienting and alarming event. This guide provides the essential, life-saving information you need to navigate it safely. We will outline the primary causes, detail the full spectrum of warning signs, and provide clear, step-by-step instructions on effective treatment, including the "Rule of 15," so you can confidently and correctly manage a hypoglycemic event and know when it’s time to seek emergency help.

Understanding Hypoglycemia: Causes, Symptoms & Treatment

Causes of Low Blood Sugar

Several factors can trigger hypoglycemia. These include:

  • Medication: Taking too much insulin or certain oral diabetes medications.
  • Skipped Meals: Not eating regularly can lead to a drop in blood sugar.
  • Excessive Exercise: Physical activity without sufficient carbohydrate intake.
  • Alcohol Consumption: Especially on an empty stomach, alcohol can interfere with the liver’s ability to release glucose.
  • Certain Medical Conditions: Kidney or liver problems, and hormonal deficiencies can contribute.

Recognizing the Warning Signs

Hypoglycemia symptoms can vary from person to person. It’s crucial to recognize them early to prevent a more serious episode. Symptoms can be divided into mild, moderate, and severe.

  • Mild Symptoms: Shakiness, sweating, dizziness, rapid heartbeat, hunger, irritability, anxiety, tingling in the lips or tongue.
  • Moderate Symptoms: Confusion, difficulty concentrating, blurred vision, weakness, slurred speech.
  • Severe Symptoms: Seizures, loss of consciousness, coma. This requires immediate emergency medical attention.

The "Rule of 15" – Your First Line of Defense

The "Rule of 15" is the standard treatment for mild to moderate hypoglycemia and is a straightforward, easily remembered method to bring your blood sugar back to a safe level.

  1. Test Your Blood Sugar: If possible, confirm your low blood sugar with a glucose meter.
  2. Consume 15 Grams of Fast-Acting Carbohydrates: Examples include:
    • 4 ounces (1/2 cup) of juice or regular soda (not diet)
    • 1 tablespoon of honey or sugar
    • Glucose tablets (follow package instructions)
    • Hard candies (about 3-4 pieces)
  3. Wait 15 Minutes: Allow the carbohydrates time to be absorbed into your bloodstream.
  4. Recheck Your Blood Sugar: After 15 minutes, test your blood sugar again.
  5. Repeat if Necessary: If your blood sugar is still below 70 mg/dL (or your target range), repeat the "Rule of 15" until your blood sugar reaches a safe level.

Important Considerations and Precautions

  • Carry Fast-Acting Glucose: Always keep a source of fast-acting glucose readily available, especially if you are prone to hypoglycemia.
  • Inform Others: Let family, friends, and coworkers know about your hypoglycemia and how to assist you in case of an emergency.
  • Glucagon Emergency Kit: Individuals at risk of severe hypoglycemia should have a glucagon emergency kit prescribed by their doctor. Learn how to administer it and ensure others know how to use it.
  • Medical Identification: Wear a medical identification bracelet or carry a card indicating you have diabetes and are prone to hypoglycemia.
  • Regular Monitoring: Consistent blood sugar monitoring is essential for preventing hypoglycemia.
  • Follow Your Doctor’s Instructions: Adhere to your prescribed medication regimen and dietary recommendations.

When to Seek Emergency Medical Attention

  • Unconsciousness: If you lose consciousness, you need immediate medical assistance.
  • Seizures: If you have a seizure, seek emergency medical care.
  • Inability to Swallow: If you are unable to swallow or are at risk of choking, call for emergency help.
  • Confusion or Disorientation: If you are severely confused or disoriented and unable to manage your blood sugar, seek immediate medical attention.
