Understanding the importance of maintaining accurate glucose readings, we are committed to providing you with valuable insights to help you overcome any sensor-related hurdles.

Understanding Dexcom G7 sensor failure

Dexcom G7 sensor failure refers to situations where the continuous glucose monitoring system fails to provide accurate and reliable 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 causes 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 reasons behind sensor failure can help you troubleshoot and address the issue more effectively. Several factors may contribute to Dexcom G7 sensor failure:

Insertion problems

Improper insertion of the sensor can lead to inaccurate readings. If the sensor is not securely placed or inserted at the correct angle, it may not function optimally.

Sensor aging

As the sensor ages, its accuracy may decline, leading to discrepancies in glucose readings over time. Regular sensor replacement is essential to maintain reliable results.

Sensor calibration

Inaccurate calibration or failure to calibrate the sensor when prompted can affect the system’s performance and lead to unreliable readings.

Compression and pressure issues

Applying excessive pressure or compression on the sensor site, especially during sleep or physical activities, can interfere with the sensor’s ability to accurately measure glucose levels.

Interference from medications or supplements

Certain medications or supplements may interfere with the sensor’s readings, causing inaccuracies.

Troubleshooting Dexcom G7 sensor failure

Now that we have a better understanding of Dexcom G7 sensor failure, let’s explore some troubleshooting steps:

Double-check sensor insertion

If you suspect a sensor issue, start by ensuring proper sensor insertion. Follow the manufacturer’s guidelines carefully and make sure the sensor is securely placed on a clean, dry 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.
