Sensible use of the Dexcom G7
We have been utilizing the Dexcom G6 CGM for a while, making it a simple comparability to the brand new G7. The scale distinction is deceivingly minuscule when holding them side-by-side.

Because the Dexcom G6 should go in a clip, its measurement is noticeably bigger when worn. The G7 additionally has beveled edges, permitting clothes to move extra simply on high of it with out getting caught.

In our pattern photograph above, you possibly can see how far more slim the G7 is when simply positioned on the pores and skin. It should sit extra flush with the adhesive utilized.
The G7 has a soft-touch end that’s nearly rubber-like however is not as cheesy as rubber or silicone. The G6 has a tough, slippery exterior.
