Thanks for choosing the Dexcom G7 Continuous Glucose Monitoring (CGM) System
(G7)! Using this medical device, you'll see your glucose readings on your display
device just by wearing a tiny sensor!
Here are some of the benefits of using G7 to manage your glucose:
No more fingersticks: G7 allows you to make treatment decisions without
l
fingersticks. (If your glucose alerts and readings from the G7 do not match
symptoms or expectations, use a blood glucose meter to make diabetes treatment
decisions.)
Predict and prevent highs and lows: With G7, you have the information needed
l
to keep your glucose in range, you can customize your alert schedule, and you get
a 20-minute warning when your glucose is quickly heading towards 55 mg/dL.
Stay informed: See the results of your actions in the summary reports and keep
l
improving.
So let's get started!

Questions and answers
Dexcom G7 continues to show readings 50 or 60 points higher than when I stick my finger and use the supplied recorder. Why?
The Dexcom G7 may show readings 50 or 60 points higher than fingerstick measurements due to several reasons:
1. Sensor's First Day: Newly inserted sensors may show larger differences, which usually decrease over the first 24 hours.
2. Pressure on Sensor: If something is pressing on the sensor (e.g., lying on it), it can affect readings. Removing the pressure can help.
3. Rapid Glucose Changes: Blood glucose changes before interstitial fluid glucose, so fast changes can cause differences between meter and sensor readings.
4. Fingerstick Issues: Inaccurate fingerstick readings can occur if hands are not washed properly or test strips are expired or used incorrectly.
These factors can cause temporary differences between Dexcom G7 and fingerstick readings.
