Managing diabetes has come a long way. If you’re using the Dexcom G6, you already know what a game-changer it is. Instead of stopping what you’re doing to prick your finger multiple times a day, you can simply glance at your phone or your Dexcom G6 receiver and see your glucose readings in real time. That kind of freedom allows people to focus more on living their lives and less on constantly checking their blood sugar.
But while the technology is incredible, there’s one small but important part of the process that everyone has to deal with: removing the sensor. It sounds easy, but if you’ve ever pulled at a stubborn patch, you know it’s not always that simple. The adhesive can cling tightly, the skin might feel a little irritated, and you may be worried about damaging the reusable transmitter.
This guide is here to take that stress away. With the right prep and a gentle technique, you can remove the Dexcom G6 sensor without discomfort, keep your skin in good shape, and smoothly transition to your next sensor.
What Makes the Dexcom G6 Special?
Before we dive into removal, let’s talk about why the Dexcom G6 regular system is such a trusted tool for diabetes care.
The system is made up of three parts:
-
Dexcom G6 Sensor - A small device that sits just under your skin and measures glucose in your interstitial fluid.
-
Transmitter - A reusable piece that snaps into the sensor housing and wirelessly sends glucose readings.
-
Dexcom G6 Receiver or app - The device that shows your glucose levels, trends, and alerts.
Unlike earlier models or traditional fingersticks, the Dexcom G6 doesn’t require routine calibration. Once inserted, it tracks your glucose around the clock for 10 days before it needs to be changed. That means you’ll be removing and replacing the sensor fairly often, so it’s worth mastering the removal process.
Why Removal Is More Important Than You Think
Some people might wonder: “Why not just peel it off quickly like a bandage?” The answer is simple: your skin and your transmitter need to be protected.
Here’s what can happen if removal isn’t done carefully:
-
Skin irritation: Tugging too hard or pulling quickly can cause redness or tiny tears in the skin.
-
Adhesive residue: Sticky patches left behind can feel uncomfortable and may interfere with your next sensor.
-
Transmitter damage: Since the transmitter is designed to last about three months, it’s important not to accidentally snap or bend it while removing the sensor.
Taking just a little more time and using the right method means you’ll feel less discomfort and keep your device working properly.
Step 1: Gather Your Supplies
Think of this as setting yourself up for success. Having everything on hand means you won’t have to stop halfway through or scramble for what you need.
Here’s a checklist:
-
A soft cloth with warm water (and mild soap if you prefer)
-
Alcohol wipes for cleaning the site after removal
-
Adhesive remover spray or wipes (highly recommended for easy peeling)
-
A small bag or disposal container for the used sensor
-
Your fresh Dexcom G6 sensor, so you’re ready for the next application
-
Optional: Skin Grip patches or other adhesives if you normally use them for extra hold
This small bit of preparation makes the removal process much smoother and less stressful.
Step 2: Loosening the Adhesive
Now comes the part most people get nervous about, peeling off the patch. The Dexcom G6 sensor is designed to stick firmly through showers, workouts, and everyday life, which is great when you’re wearing it, but not so fun when you’re ready to take it off.
Here’s how to make it easier:
-
Start at the edge of the patch and slowly lift it.
-
Hold your skin taut with your free hand as you peel, which helps reduce pulling.
-
If the adhesive resists, apply adhesive remover directly around the patch.
-
Wait a minute or two for the remover to break down the sticky layer.
-
Continue peeling slowly until the sensor comes free.
Some people like to press a warm washcloth against the adhesive first. The heat helps loosen it so it comes off more gently.
Step 3: Detaching the Transmitter
Once the patch and sensor are off, you’ll see the transmitter clipped into the housing. This part is reusable and should not be thrown away unless the battery has expired.
To remove it safely:
-
Push down on the small lip of the holder at the wide end.
-
Slide the transmitter out carefully.
-
Store it somewhere safe until you attach it to your next sensor.
Most transmitters last between 90 and 110 days. The Dexcom G6 receiver or smartphone app will alert you when the battery is running low, so you’ll know when it’s time for a replacement.
Step 4: Clean the Skin
After removal, check the skin for any irritation or leftover adhesive.
-
Wash the area with warm water and soap, then rinse.
-
Use an alcohol wipe if needed to remove residue.
-
Pat the skin dry gently, don’t rub too hard.
If your skin looks red or sensitive, give that spot a break before placing another sensor there.
Getting Ready for Your Next Sensor
When it’s time to apply your new Dexcom G6 sensor, consider changing the location. Rotating sites helps prevent irritation and ensures more consistent readings.
For adults, the abdomen and back of the arm are the most common placements. For children, the upper buttocks are often recommended.
If you’ve noticed any sensitivity in one area, skip it next time and allow your skin to recover.
Dexcom G6 vs. Dexcom G7 Sensor: Removal Differences
The Dexcom G7 sensor is the newer generation and has a slightly different design. It’s smaller, more discreet, and the transmitter is built in, which means you don’t reuse it. When you remove the G7, you simply peel it off and discard the whole device.
This makes removal faster and simpler compared to the Dexcom G6 regular system, where you have to be mindful about saving the transmitter. Still, many users remain loyal to the G6 because of its availability, insurance coverage, and compatibility with their existing devices.
Tips for Easier Removal Every Time
-
Always loosen the adhesive with remover or warm water.
-
Don’t rush; slow, steady peeling prevents skin irritation.
-
Hold your skin taut as you peel to reduce pulling.
-
Keep your new sensor ready so you can transition quickly.
-
Rotate sites regularly for healthier skin.
-
If you’re sensitive to adhesives, try barrier wipes before your next application.
Final Thoughts:
Removing the Dexcom G6 doesn’t have to be something you dread. With the right preparation and gentle techniques, it’s quick, painless, and sets you up for a smooth transition to your next sensor. Whether you stick with the trusted G6 or switch to the sleeker Dexcom G7 sensor, the key is the same: keeping your skin healthy, your device protected, and your diabetes care stress-free.
