Adhesive patch
Issue
The adhesive patch is peeling off your body.
Solution
Follow the insertion instructions carefully. Extra care may help you keep your sensor
on for the entire sensor session.
Site preparation
Site: Sensor site should be flat, clean, and completely dry before you insert the
l
sensor. There should be some fat under the skin at the sensor site.
Extra adhesive: Put on additional adhesive over the patch before applying the
l
overpatch. Let dry. For more recommendations, go to dexcom.com/faqs or in the
app go to Profile > Help > Find Answers
Placement: The patch stays on best when it isn't where your skin folds when you
l
bend or near waistbands that could rub against it.
Avoid hair: Apply the patch to areas without much hair. If needed, shave site with
l
electric clippers.
Old adhesive: Remove any adhesive residue from previous sensors. Consider
l
using a body oil or adhesive remover for skin (such as Uni-solve, Detachol, or Tac
Away).
Patch care
The longer you keep it dry and sweat-free in the first 12 hours, the longer it may
l
stick to your skin
When it gets wet, gently pat it dry as soon as you can
l
If it peels off your skin, trim the peeled parts and put on medical tape

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.
