The Rule of 15: Your Go-To Treatment Method

The "Rule of 15" is a simple, effective protocol for treating mild to moderate hypoglycemia:

  1. Check Your Blood Sugar: If possible, confirm your blood sugar is low (usually below 70 mg/dL).
  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
    • Hard candies (check label for carbohydrate content)
    • Glucose tablets
  3. Wait 15 Minutes: Allow the carbohydrate to be absorbed.
  4. Recheck Your Blood Sugar: Test again after 15 minutes.
  5. Repeat if Necessary: If your blood sugar is still low, repeat the Rule of 15.

Beyond the Rule of 15: What to Do After Treatment

Once your blood sugar returns to a safe level (usually above 70 mg/dL), it's crucial to prevent another episode:

  • Eat a Meal or Snack: Follow the treatment with a meal or snack containing protein and carbohydrates. This helps stabilize your blood sugar and prevent a rebound.
  • Investigate the Cause: Try to determine what triggered the hypoglycemia. Was it a missed meal, too much medication, or excessive exercise? Identify patterns and adjust your routine accordingly.
  • Inform Others: If you frequently experience hypoglycemia, let your family, friends, and coworkers know how to recognize the signs and assist you.
  • Medical Consultation: Discuss recurrent hypoglycemia with your doctor. They can help you adjust your medication, diet, or exercise plan.

When to Seek Emergency Medical Help

  • Unconsciousness: If you are unable to treat yourself due to loss of consciousness.
  • Seizures: If you experience a seizure.
  • Severe Confusion: If you are significantly confused and unable to care for yourself.
  • Unresponsiveness: If you are unable to respond to treatment.
