Actions to Reduce the Risk of Severe Lows
Actions You Can Take To Help Prevent Severe Low Blood Sugar
When your daily routine changes, test your blood sugar more often to track your levels.
Watch out for early warning signs of low blood sugar when your daily routine changes.
You may not notice any signs or symptoms, but if your blood sugar is less than 70 mg/dL, you need to take action to treat it.
Keep snacks with fast-acting carborhydrates with you. Fast-acting carbohydrates are in food like:
- Hard candies
- Fruit
- Glucose tablets
Treat low blood sugar before it becomes severe by following the 15-15 rule.
What is the 15-15 rule?
15 grams of carbohydrates – 15 minutes
To treat non-severe low blood sugar as soon as signs or symptoms appear:
- Eat or drink 15 grams of fast-acting carbohydrates, such as:
- Half a cup of juice
- 5-6 hard candies
- 6 large jellybeans
- 4 glucose tablets
- Avoid carbohydrates that are also high in fat, such as chocolate. These are absorbed slower and take longer to
raise your blood sugar. - After 15 minutes, if you still have symptoms or if your blood sugar is still less than 3.9 mmol/L (70 mg/dL), eat or drink another 15 grams of fast-acting carbohydrates.
- When your blood sugar starts to return to normal, eat a meal or snack to prevent another low blood sugar event
Ask Your Healthcare Provider About:
How your diabetes medicines work and how to take them correctly.
Make an emergency plan, including having glucagon (rescue medication for severe low blood sugar) on hand. Make sure your caregivers know about the signs and symptoms of low blood sugar, and how and when to administer glucagon – just in case.
