The Dexcom G7 sensor may show a failure message after pairing due to issues such as using an outdated sensor version that is not compatible with certain devices, signal loss, or sensor adhesion problems.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?

1 comments:

Mr. Anderson

February 10, 2025

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.
