The following article comes from Apple Insider, Dec. 8-14, 2022. 

First look at the new Dexcom G7 glucose monitor Andrew O'Hara | Dec 13, 2022
Holding the new Dexcom G7 CGM

After months of international availability, the Dexcom G7 constant glucose
monitor received its FDA clearance to distribute in the US. Ahead of the
wide rollout, we got to go hands-on with a demo model to see how it looks
and fits. Initially, Dexcom had hoped to launch the G7 much earlier here
stateside. But a massive rewrite to the mobile app and sensor algorithms
prompted increased scrutiny from the FDA before it could begin sales. 

It launched first abroad before the FDA clearance came in early December.
The device is still unavailable to order in the US but will start hitting
pharmacies in early 2023. 

Now that the final certification is in, we got a demo model that shows off
the final form factor, insertion process, and how it compares to the G6. 

What's new The Dexcom G7 is known as a CGM, or constant glucose monitor. It
sends readings every five minutes from a tiny sensor under your skin to your
smartphone or a receiver via Bluetooth. 

With the G7, Dexcom has continued to refine the product with several
improvements over the G6. 

Smaller design Faster warmup period New mobile app with Clarity reporting
built in 12-hour grace period for migrating to a new sensor New wear
locations Less plastic waste New insertion device Better, more customizable
alerts Comparing the Dexcom G7 to a quarter The biggest of the changes is
the new design, which is 60 percent smaller than its predecessor. It's an
all-in-one design that combines the previously-separate transmitter and
sensor. 

This requires a new insertion tool that looks more akin to the Freestyle
Libre with a button on the side. The whole unit is disposable, no longer
requiring the transmitter to be reused. 

It connects to the redesigned G7 app, which is yet to release in the US. The
new app combines the Dexcom Clarity app with the CGM app so you can view
your CGM data and reports in one location. 

The new app has more granular alerts too. These new alerts can be
personalized to your needs and can be more discrete. 

The Dexcom G7 only requires a 30-minute warm-up, compared to two hours with
the G6, and still requires no manual fingerstick calibration. 

Dexcom allows a 12-hour grace period when the sensor expires, which is
excellent for parents with children. They no longer have to decide between
sending them to school with a sensor about to expire and ending the wear
session early. 

Finally, the G7 is approved to be worn in two new body locations. The G6 was
only supposed to be worn on the abdomen. The G7 can be worn on the arm for
those older than two, and on the upper buttocks for kids ages two through
17. 

G6 app on Apple Watch Post-launch, Dexcom has told AppleInsider that it
plans to allow the G7 to connect directly to Apple Watch without requiring
the iPhone as an intermediary. 

This will allow users to leave their iPhone behind, possibly for a workout,
and still receive glucose readings on their Apple Watch. 

Practical use of the Dexcom G7 We've been using the Dexcom G6 CGM for some
time, making it an easy comparison to the new G7. The size difference is
deceivingly minuscule when holding them side-by-side. 

Wearing the Dexcom G6 and G7 As the Dexcom G6 must go in a clip, its size is
noticeably larger when worn. The G7 also has beveled edges, allowing
clothing to pass more easily on top of it without getting caught. 

Side view of of the Dexcom G7 and G6 In our sample photo above, you can see
how much more slim the G7 is when just placed on the skin. It will sit more
flush with the adhesive applied. 

The G7 has a soft-touch finish that is almost rubber-like but isn't as tacky
as rubber or silicone. The G6 has a hard, slippery exterior. 

Dexcom G7 sensor We like the new insertion tool that is even easier to use
than the G6 model. The sensor is magnetically held in place and inserted
with a button. 

A cap is screwed onto the bottom, making for quick disposal. 

Coming in 2023 Our demo model is non-functioning, meaning we still need to
test the accuracy or connectivity features. 

The app and sensor will begin shipping in early 2023 and requires a
prescription to order. Dexcom says it is continuing to work with insulin
pump providers, such as Tandem, to support the new sensors as fast as
possible.
