The Dexcom G7 CGM System gives people with diabetes an opportunity to check their glucose levels at a glance—no scanning, calibration or fingerstick tests required.* To accomplish this, the system relies on a small sensor/transmitter that sends glucose updates to a dedicated reader or smart device.¶
Dexcom G7 sensors are very discreet and have a low profile, thanks to the 60% reduction in size† when compared to previous models. These sensors also warm up faster than any other CGM sensor††. The 12-hour “grace period” at the end of the 10-day service life, allows users to switch to a new sensor at a time that’s convenient.
G7 Sensor Placement
It is important to change your insertion site every time you change your sensor. This will prevent skin irritation and scarred tissue. For ages two years and older, Dexcom G7 Sensors should be inserted on the back of the upper arm. The sensor can be placed on the upper buttocks for children between the ages of 2 – 6 years old.
Failure to use the Dexcom Continuous Glucose Monitoring System and its components according to the instructions for use provided with your device and available at https://www.dexcom.com/safety-information and to properly consider all indications, contraindications, warnings, precautions, and cautions in those instructions for use may result in you missing a severe hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose) occurrence and/or making a treatment decision that may result in injury. If your glucose alerts and readings from the Dexcom CGM do not match symptoms, use a blood glucose meter to make diabetes treatment decisions. Seek medical advice and attention when appropriate, including for any medical emergency
Q: How Long Will A Dexcom G7 Sensor Last?
A: The sensors used in the Dexcom G7 CGM System are designed for ten days of wear (not including a 12-hour grace period after this time elapses).
How Long Does The Dexcom G7 Sensor Last Compared To The G6?
A: Both the Dexcom G7 and G6 sensors have a 10-day lifespan. However, the G7 sensor adds a 12-hour grace period to this timespan. Also, it only has a 30 minute sensor warm-up time compared to the G6’s 2-hour warm up time.
Q: Can I Put The Dexcom G7 Sensor On My Stomach?
A: For adults and children 2 years and older, users should wear the G7 sensors on the back of the upper arm. Children between the ages of 2-6 years old can also wear senors on their upper buttocks.
Q: Are The Dexcom G7 Sensors Waterproof?
A: G7 sensors are waterproof for up to 8 feet (2.4 meters).§ These sensors can also safely deal with water from swimming, showering, and bathing. Water may temporarily affect your ability to receive glucose readings and reduce your patch’s adhesion to your body. The Dexcom G7 receiver is not waterproof but is splash resistant.
Q: Does The Dexcom G7 Need to Be Calibrated?
A: When starting a new sensor, you do not need to calibrate your Dexcom G7 CGM System. However, you can calibrate it by logging this as an event in the G7 App.
Q: How Many Dexcom G7 Sensors Come in a Box?
A: The Dexcom all-in-one sensor and transmitter box contains a single sensor/transmitter. As part of our service, we ship 90-day supplies of Dexcom G7 Sensors to reduce the chances of you running out before your next order.
Q: Can You Extend The Dexcom G7 Sensor?
A: You cannot use the G7 all-in-one sensor/transmitter past 10 days. You can benefit from the 12-hour grace period at the end of each sensor’s 10-day lifespan.
Q: Can The Dexcom G7 All-In-One Sensor and Transmitter Be Worn During Pregnancy?
A: Yes, the Dexcom G7 can be worn during pregnancy for all types of diabetes (type 1, type 2, or gestational).
