How to Protect a Dexcom G7, G7 15 Day or Stelo Sensor

A CGM is worn through everyday life: getting dressed, sleeping, exercising, working and moving through tight spaces. For people using Dexcom G7, Dexcom G7 15 Day or Stelo, protection can involve more than one approach.

The main accessory categories include reusable armbands, sensor covers and guards, adhesive overpatches and skin barrier underpatches.

Use an overpatch for additional adhesive coverage

A compatible CGM overpatch adds adhesive coverage around the sensor site. This can be useful when additional reinforcement is desired during daily wear or activity.

Add a guard or cover for physical protection

A sensor guard or cover is designed to provide a physical barrier around a compatible CGM. This can help shield the sensor area from everyday bumps and snags that adhesive alone does not address.

Consider a reusable CGM armband

A reusable band provides another way to add physical security around the sensor area. Our Freedom Band system can be paired with compatible cases and guards rather than relying only on additional adhesive.

What about underpatches?

An underpatch is worn beneath a compatible sensor and creates a layer between the device adhesive and skin. Underpatches and overpatches serve different purposes: one goes beneath the sensor while the other reinforces the area from above.

Build a Dexcom protection setup

You do not necessarily have to choose only one accessory type. Compatible products can be combined when they are specifically designed to work together.

See our complete Dexcom G7, G7 15 Day & Stelo protection collection for Freedom Bands, sensor covers, guards, overpatches, underpatches and starter kits.

Protection during sports, sleep and daily activity

Different routines create different risks. Sports may increase the chance of contact, clothing can snag a sensor edge, and sleep can place pressure around the sensor area. Choose accessories based on the type of protection you actually need and follow the device manufacturer's wear instructions.
