It’s important to be aware that some people experiencing hypoglycemia may not display obvious symptoms, particularly if they’re used to having low blood sugar. This is why regular blood sugar monitoring is essential.
The Rule of 15: Your First Line of Defense
The "Rule of 15" is the standard treatment for mild to moderate hypoglycemia and should be your immediate response. Here's how it works:
- Check Your Blood Sugar: If possible, confirm your blood sugar level with a glucose meter. A reading below 70 mg/dL (3.9 mmol/L) generally indicates hypoglycemia. However, don't delay treatment if you suspect hypoglycemia and don't have a meter readily available.
- Consume 15 Grams of Quick-Acting Carbohydrates: Choose from the following options:
- 4 ounces (1/2 cup) of juice or regular soda (not diet)
- 1 tablespoon of honey or maple syrup
- 1 tube of glucose gel (check label for grams of carbohydrates)
- Hard candies (check label for grams of carbohydrates - typically 4-5 pieces are needed)
- Glucose tablets (follow package instructions for dosage)
- Wait 15 Minutes: After consuming the carbohydrates, wait 15 minutes.
- Recheck Your Blood Sugar: After 15 minutes, recheck your blood sugar level.
- Repeat if Necessary: If your blood sugar is still below 70 mg/dL (3.9 mmol/L), repeat the Rule of 15.
- Follow Up with a Longer-Acting Snack: Once your blood sugar is above 70 mg/dL (3.9 mmol/L), consume a snack containing both carbohydrates and protein to prevent another drop. Good choices include:
- Peanut butter and crackers
- Cheese and whole-grain bread
- Yogurt with granola
When to Seek Emergency Help
While the Rule of 15 is effective for many, there are situations where immediate medical attention is crucial:
- Unconsciousness: If the person is unconscious or unable to swallow, do not attempt to give them anything by mouth. Call emergency services immediately.
- Seizures: If the person experiences a seizure, call emergency services immediately.
- Severe Confusion: If the person is severely confused and unable to recognize you or their surroundings, call emergency services.
- Repeated Hypoglycemic Episodes: If the person experiences frequent or severe hypoglycemic episodes, consult with their healthcare provider to identify and address the underlying cause.
- Rule of 15 not Working: If the blood sugar does not respond to repeated applications of the rule of 15.
Important Considerations
- Glucagon: Individuals at risk for severe hypoglycemia should discuss obtaining a glucagon emergency kit with their healthcare provider. Glucagon is a hormone that can rapidly raise blood sugar levels and is administered by injection. Family members, friends, and caregivers should be trained on how to administer glucagon.
- Medical Identification: Wear a medical identification bracelet or necklace that indicates you have diabetes and are prone to hypoglycemia.
- Communicate with Others: Inform family members, friends, and coworkers about your diabetes and how they can assist you in the event of a hypoglycemic episode.
- Underlying Causes: Frequent hypoglycemia can indicate an underlying medical condition or medication issue. Consult with your healthcare provider to investigate potential causes and adjust treatment as needed.
- Record Keeping: Keeping a log of your blood sugar levels, meals, exercise, and any hypoglycemic episodes can help you and your healthcare provider identify patterns and make necessary adjustments to your diabetes management plan.
