Managing diabetes can be challenging, but with the right tools, it becomes much easier. The Dexcom Continuous Glucose Monitoring (CGM) system is a game-changer for many, offering real-time glucose readings without the need for constant finger pricks. However, like any wearable device, the Dexcom sensor requires regular replacement. In this guide, we’ll cover everything you need to know about sensor replacement, including tips, product recommendations, and FAQs.
What is a Dexcom Sensor?
The Dexcom sensor is a small, wearable device that measures glucose levels in your interstitial fluid (the fluid between your cells). It works with a transmitter to send real-time glucose data to your smartphone or receiver. The sensor is typically worn on the abdomen or back of the arm and needs to be replaced every 10 days for optimal accuracy.
Why Replace Your Dexcom Sensor?
Replacing your Dexcom sensor is essential for maintaining accurate glucose readings. Over time, the sensor’s performance can degrade, leading to less reliable data. Here’s why timely replacement matters:
- Accuracy: A fresh sensor ensures precise glucose readings.
- Comfort: Worn-out sensors may cause skin irritation.
- Safety: Accurate data helps you make informed decisions about insulin and diet.
How Often Should You Replace Your Dexcom Sensor?
Dexcom recommends replacing the sensor every 10 days. However, some users extend the sensor’s life by restarting it, though this is not officially supported by Dexcom. Always prioritize accuracy and safety over extending usage.

Personal Experience
As someone who has used the Dexcom G6 for over a year, I can confidently say that the replacement process is straightforward. The first time was a bit nerve-wracking, but after a few tries, it became second nature. I highly recommend using adhesive patches, especially during workouts, as they prevent the sensor from peeling off. The G7’s shorter warm-up time is a game-changer for those who want quicker access to their glucose data.
Tips
