Thanks for choosing the Dexcom G7 Continuous Glucose Monitoring (CGM) System
(G7)! Using this medical device, you'll see your glucose readings on your display
device just by wearing a tiny sensor!
Here are some of the benefits of using G7 to manage your glucose:
No more fingersticks: G7 allows you to make treatment decisions without
l
fingersticks. (If your glucose alerts and readings from the G7 do not match
symptoms or expectations, use a blood glucose meter to make diabetes treatment
decisions.)
Predict and prevent highs and lows: With G7, you have the information needed
l
to help keep your glucose in range. G7 also lets you customize your alerts and you
get a 20-minute warning when your glucose is quickly heading towards
55 mg/dL.
Bring more peace of mind: G7 lets you share glucose data with your support
l
team to keep them informed about your glucose levels in real time.
Stay informed: See the results of your actions in the summary reports and keep
l
improving.
So let's get started!

Questions and answers
changed sensor, it paired but get a message sensor failed start new sensor
The Dexcom G7 sensor may show a failure message after pairing due to issues such as using an outdated sensor version that is not compatible with certain devices, signal loss, or sensor adhesion problems. If pairing with a Tandem hybrid closed-loop system, an older Dexcom T7 version may cause an error message like "sensor not started 43t." Checking the sensor's LBL number and ensuring compatibility can help resolve the issue. If the problem persists, contacting Dexcom for a replacement may be necessary.

How long after eating does readings reach the sensor?
The Dexcom G7 sensor measures glucose in interstitial fluid, not blood, and glucose levels in interstitial fluid can lag behind blood glucose levels, especially when glucose is changing rapidly. This means that after eating, the sensor reading may take some time to reflect actual blood glucose changes. The exact time can vary, but differences are more noticeable when glucose levels are rising or falling quickly.

Wait time between showing & inserting new G7 sensor
The Dexcom G7 sensor has a 12-hour grace period at the end of its session, allowing time to replace the sensor. After inserting a new sensor, there is a sensor warm-up period before readings and alerts begin.
