Sends glucose readings to a receiver or smart device—no scans required

When used alongside the Dexcom G6 CGM System as a whole, the system’s transmitter gives diabetes patients the ability to monitor their glucose levels without fingerstick tests in most situations. However, users must still perform “regular” glucose tests when their CGM readings do not align with their expectations or symptoms.

Dexcom G6® Transmitter

With the Dexcom G6® Continuous Glucose Monitoring (CGM) System, people living with type 1 and type 2 diabetes can enjoy fingerstick-free* glucose testing. To accomplish this, the system uses advanced wearable transmitters that deliver real-time glucose updates to a user’s receiver or smart device once every five minutes, with no scanning. If you’re looking for replacement transmitters for your Dexcom G6 CGM System, there’s no better place to order them than Advanced Diabetes Supply.

How much time per day do you spend testing your blood glucose? With the Dexcom G6 CGM System, you can get glucose updates the easy way by wearing a small transmitter that keeps an eye on your glucose for you. As a result, you’ll be able to live your life without worrying about your next fingerstick test.*

The transmitters used in the Dexcom G6 CGM System are highly discreet thanks to their small size and painless application process. But even if you forget you’re wearing your transmitter, it will still be sending glucose updates to your reader or smart device every five minutes!

Comprehensive safety information on the Dexcom G6 CGM System and its sensors can be found here.

Q: How Long Does the Dexcom G6 Sensor Last?

A: The transmitters used in the Dexcom G6 CGM System have a lifespan of ten days. Unlike the Dexcom G7 CGM System’s transmitters, the G6 lifespan is not followed by a grace period.

Q: Is the Dexcom G6 Sensor Painful to Put on?

A: The Dexcom G6 auto applicator was designed for easier, more consistent sensor insertions. According to a survey of Dexcom G6 users, 84% reported that the initial sensor insertion was painless and 100% reported that the applicator was easy to use1

Q: Can I Shower With the Dexcom Transmitter On?

A: Yes, because the transmitters used in the Dexcom G6 CGM System are water-resistant. However, the receivers used in this system should stay dry.

Q: How Do I Remove My Dexcom G6 Transmitter?

A: To remove your Dexcom G6 CGM System transmitter, follow the steps shown in this instructional video.

Q: Does the Dexcom Sensor Pierce The Skin?

A: The Dexcom G6 CGM System’s transmitter is designed to analyze interstitial fluid. The insertion needle needs to puncture the skin’s dermis layer to access this fluid; to prevent bleeding, be sure to follow the proper application technique.

Q: Is the Dexcom G6 Transmitter Implanted?

A: The transmitters used in the Dexcom G6 CGM System are not implanted. They are fastened on top of the sensor. They are designed for wear discreetly on a user’s abdomen for ages 2 years and older or if between the ages of 2 and 17—on their upper buttocks.

Q: What Happens If My Dexcom G6 Transmitter Falls Off?

A: When your Dexcom G6 CGM System transmitter is partially or fully dislodged, avoid pushing this device back into place. Instead, remove your transmitter, apply a replacement, and order additional transmitters if your stock is running low.

*If glucose alerts and readings from Dexcom G6 do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.
