Understanding the Basics of Hypoglycemia

Hypoglycemia occurs when your blood glucose level drops below 70 mg/dL. While levels below this are generally considered low, individual thresholds can vary. Several factors can trigger hypoglycemia, including:

  • Medication Errors: Taking too much insulin or other diabetes medications.
  • Missed or Delayed Meals: Not eating enough carbohydrates.
  • Excessive Exercise: Increased activity without adjusting medication or food intake.
  • Alcohol Consumption: Alcohol can interfere with the liver’s ability to release glucose.
  • Kidney or Liver Problems: These conditions can affect how your body processes glucose.

Recognizing the Signs and Symptoms

Hypoglycemia symptoms can vary from person to person, and even for the same person at different times. It’s important to be aware of your own body's signals. Symptoms typically progress in severity:

Mild to Moderate Symptoms:

  • Shakiness
  • Sweating
  • Dizziness or lightheadedness
  • Hunger
  • Rapid heartbeat
  • Irritability or anxiety
  • Confusion
  • Headache
  • Blurred vision

Severe Symptoms (Require Immediate Assistance):

  • Severe confusion or disorientation
  • Seizures
  • Loss of consciousness
  • Inability to swallow

The Rule of 15: Treatment for Mild to Moderate Hypoglycemia

The “Rule of 15” is the standard treatment for mild to moderate hypoglycemia. Follow these steps:

  1. Check Your Blood Sugar: If possible, use a blood glucose meter to confirm that your blood sugar is 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 syrup
    • Hard candies (approximately 3-4)
    • Glucose tablets (follow package instructions)
  3. Wait 15 Minutes: Allow the carbohydrates time to raise your blood sugar.
  4. Recheck Your Blood Sugar: After 15 minutes, check your blood sugar again.
  5. Repeat if Necessary: If your blood sugar is still below 70 mg/dL, repeat the process (Step 1-4) until your blood sugar is within a safe range.
  6. Follow-up snack: After blood sugar is back to normal, have a snack containing both carbohydrates and protein (e.g., crackers with peanut butter) to prevent another drop.

If someone is experiencing severe hypoglycemia (unconscious, seizing, or unable to swallow), do the following:

  1. Call for Emergency Medical Help Immediately: Dial 911 or your local emergency number.
  2. Administer Glucagon (If Available): Glucagon is a hormone that stimulates the release of glucose from the liver. If you have been prescribed glucagon and know how to administer it, do so according to your doctor’s instructions. Important: Even if glucagon is administered, still call for emergency medical assistance.
  3. Do Not Give Anything by Mouth: Do not attempt to give food or liquids to someone who is unconscious or having seizures. This can cause choking.
  4. Stay With the Person: Remain with the person until emergency medical help arrives.

Prevention Strategies

  • Regular Blood Sugar Monitoring: Check your blood sugar regularly, especially before meals, exercise, and bedtime.
  • Consistent Meal Timing: Eat meals and snacks at consistent times each day.
  • Carbohydrate Counting: Learn how to count carbohydrates to ensure you’re eating the right amount.
  • Adjust Medication as Needed: Work with your doctor to adjust your medication dosage as needed.
  • Educate Others: Inform family members, friends, and coworkers about your condition and what to do in case of a hypoglycemia emergency.
  • Carry Identification: Wear a medical ID bracelet or necklace indicating that you have diabetes.
