However, it may come across sensor-related challenges that can affect its accuracy and dependability. 

In this blog, we will see common problems related to Dexcom G7 sensor failure. You will know about the possible reasons behind such issues, and which steps you can take to resolve them. 

To Understand the importance of maintaining accurate glucose readings, we are dedicated to providing you with valuable visions to help you overcome any sensor-related problems. 

Understanding Dexcom G7 sensor failure 

Dexcom G7 sensor failure states the situations where the continuous glucose monitoring system fails to deliver exact and consistent readings. In this way, they leave users uncertain about their blood sugar levels. Such inaccuracies can lead to incorrect insulin dosing decisions, potentially impacting diabetes management as well as overall health. Let us discuss some common types of errors that cause Dexcom G7 sensor failure 

Dexcom G7 false low reading 

The Dexcom G7 sensor may show a false low reading. Such readings are highly troublesome for the patients. It can be due to multiple reasons. One of the most common reasons in this matter is compressed or broken sensors. 

No reading at all 

Sometimes, Dexcom G7 may show no reading at all. One of the primary reasons for this Dexcom G7 sensor failure is that it is far away from the display device. Sometimes when you check it under water you may see no reading at all. 

Connectivity issues 

Connectivity issues are included in the most common ones while using the Dexcom G7 sensor. It may be due to the error of the mobile App. This failure can also occur because of poor Bluetooth signals.

Common signs of sensor failure 

Identifying potential sensor failures is vital for prompt action. Here are some common signs that may indicate Dexcom G7 sensor failure: 

Inconsistent readings: Frequent fluctuations or sudden drops/spikes in glucose readings that don’t match your physical condition or other blood sugar measurements.  

No signal or communication error: Your Dexcom G7 receiver or app displays “No Signal” or “Communication Error” messages.  

Calibration issues: The sensor may prompt frequent calibrations, yet the readings remain inaccurate.  

Unreliable trend arrows: The trend arrows indicating blood sugar direction may not align with how you feel. 

Sensor not lasting full 10 days: Premature sensor failure, where the sensor stops functioning before the recommended wear time. 

Potential causes of Dexcom G7 sensor failure 

Understanding the possible causes behind sensor failure can help you troubleshoot and address and troubleshoot the issue more efficiently. Numerous issues may contribute to Dexcom G7 sensor failure: 

Insertion problems 

 Inaccurate readings occur when the insertion of the sensor is improper. If the sensor is not firmly placed or injected at an accurate angle, it will not function optimally. 

Sensor aging 

As the sensor ages, its precision may fail, leading to inconsistencies in glucose readings with time. Regular sensor replacement is essential to maintain reliable results. 

Sensor calibration 

Imprecise adjustment or failure to adjust the sensor when prompted can affect the performance of system which leads to defective readings. 

Compression and pressure issues 

When extreme pressure or compression on the sensor site is applied, particularly during physical activities or sleep, can affect the sensor’s ability to measure the glucose levels accurately. 

Interfering of medications or supplements 

Certain medications or supplements can interfere the sensor’s readings, which causes imprecisions. 

Dexcom G7 Sensor Failure

For a better understanding of Dexcom G7 sensor failure, let’s discover some troubleshooting steps: 

Double-check sensor insertion 

If you are suspicious about a sensor issue, start by confirming suitable sensor insertion. Follow the guidelines of the manufacturer wisely and make sure the sensor is firmly positioned on a dry, clean skin site. 

Monitor sensor age 

Keep track of how long the sensor has been in use. Replace it after ten days, as recommended by Dexcom, to maintain accurate readings. 

Calibrate correctly 

Calibration is not required by Dexcom G7. However, if you want to calibrate the sensor you must do it as prompted by the device. Make sure you follow the calibration process accurately. Use fingerstick tests to verify and calibrate the readings when needed. 

Avoid compression 

Be mindful of applying excessive pressure or compression on the sensor site to prevent interference with glucose readings. 

Account for medications and supplements 

If you are taking medications or supplements that might impact glucose levels, discuss this with your healthcare provider and consider additional testing to cross-verify readings.

  2. My dexcom g7 has failed 50% of the time. Can you explain what is going on. It fails as soon as it’s put on during calibration. I’ve lost 3

    1. If you’ve set a calibration, you might notice “Calibration Not Used” in your history tab.This means your Dexcom G7 sensor couldn’t use the calibration you entered, so your glucose readings may not match your blood glucose meter. If you see this message, wait a bit for the sensor to adjust. Afterward, try calibrating again in about an hour using a fresh fingerstick/finger prick.

      To ensure an accurate blood glucose meter reading, follow these steps:

      Wash your hands with soap and water.
      Dry your hands.
      Take a fingerstick/finger prick.

      We are looking forward to your feedback.

  3. Have used DexcomG7 for a while but lately it’s been loosing signal. Tried all the trouble shooting items but can’t figure out the problem since it worked so well before.

  4. Had very few issues with my G6. I switched to the G7 and have issues daily, especially what I believe are false low readings. Also it will not calibrate. I’m considering either going back to a G6 or to another brand of monitor.

    1. Hello Jeff. Sorry to hear about any inconvenience experienced. Regarding the calibration issue, please try restarting your phone once, if not already tried. And regarding the false low readings, you may check your readings using fingerstick to double check if the readings are correct or not.

      In case the issue persists, please file a complaint to Dexcom and they shall get back to you soon. They have a live chat support from 5:00 am to 5:00 pm PST. And their general call support is available from Monday to Friday 6:00 am – 5:00 pm.
