Supporting CGM Adhesion: Practical Tips for Dexcom G7 Users

For many people using a continuous glucose monitor (CGM) like the Dexcom G7, skin preparation and adhesive care can help support sensor wear and promote skin comfort — especially through daily activities, exercise, or in different weather conditions.

In this article, we’ll explore tips for supporting CGM adhesion and comfort, and how accessories like Pump Peelz decorative patches can be used to complement the look and feel of your device wear.

Understanding CGM Adhesion Basics

The Dexcom G7 sensor includes a built-in adhesive patch and optional overpatch provided by the manufacturer. Individual experiences with sensor adhesion can vary based on skin type, activity level, and environment.

Proper skin preparation and site selection are key to supporting a comfortable wear experience throughout the sensor’s intended wear period.

Factors That May Impact Adhesion

Sweat and Water

Exposure to water and sweat can sometimes affect adhesive performance. After swimming, showering, or heavy exercise, it can be helpful to gently dry the area around your sensor.

Skin Preparation

Preparing your skin before applying your CGM can help support adhesive performance:

• Wash the application area with mild soap and water.

• Allow the skin to dry completely.

• Use an alcohol wipe if recommended by your healthcare provider.

• Trim excess hair in the area if needed.

Avoid applying the sensor immediately after showering or applying lotions or oils.

Physical Activity and Movement

Movement or friction near the sensor site may place additional stress on the adhesive. Consider choosing placement areas that are less exposed to repetitive motion or rubbing.

Weather and Temperature

Hot, humid weather can contribute to sweat production, which may impact adhesive wear. Monitor the sensor site during extreme weather and discuss any concerns with your healthcare provider.

Tips for Supporting Adhesion Comfortably

Site Selection

Rotating CGM sites is important to support healthy skin. Follow manufacturer recommendations for placement areas and avoid using sites that show signs of irritation.

Supplemental Adhesive Products

Some people choose to use adhesive barrier wipes, liquid adhesives, or additional adhesive patches to support adhesion. Always consult your healthcare provider before adding products to your CGM routine.
