Scenario 2: What Would You Do? - Dexcom G5 User Manual

Your Options
You have a number of options; which would you choose?
A. Adjust insulin to correct for a low pre-meal glucose.
B. Eat fast-acting carbohydrates and adjust insulin to correct for a low pre-meal blood
sugar. Consider taking less insulin based on your immediate plans, since your trend
arrow is going down.
C. Eat your meal but don't take any insulin.
D. Eat fast-acting carbohydrate to treat the current sensor glucose reading, and delay
your meal. Do not take any more insulin.
If you chose B, you are correct!
Based on your target glucose range and how you manage a low glucose, you may need to
reduce the amount of insulin needed to cover the food you are about to eat.
Let's take at a look at why B was the best answer:
• A doesn't consider that you are recovering from a low and treated with fast-acting
carbohydrates.
You are still dropping and your glucose is not stable.
• C doesn't consider that your glucose is dropping and you're below your target
range.
However, depending on your meal and planned activities, you may still need to take
some insulin to prevent a high glucose after your meal.
• D doesn't consider that your glucose is already below target range and dropping.
Fast-acting carbohydrates will raise your glucose, and your normal meal should
help get you to your target glucose range.
Let's look at another scenario.

Scenario 2: What would you do?

Right before lunch you look at your display device and check your glucose level. The home
screen shows your sensor BG reading is 150 mg/dL with a single arrow pointing up, so you
know it is rising. After taking your normal insulin dose, you eat lunch.
About 90 minutes later, you get a High Glucose Alert.
