Ever been halfway through a workout, in the zone, and suddenly feel the edge of your Dexcom lifting? One quick wipe with your towel or brush from your shirt, and off it goes
It's not ideal when you’re relying on real-time blood glucose data to get you through.
Whether you’re into cardio, strength, yoga, or just chasing the kids round the park, keeping your CGM sensor stuck during sweaty moments can be a challenge
That’s where a good Dexcom patch comes in – not just to keep things secure, but to help you feel more confident while you move.
Why Sensors Shift Mid-Workout
Even if you apply it perfectly, sweat, heat and movement can still test your CGM’s limits. Here’s what’s usually working against you:
- Sweat makes the adhesive lift earlier than expected
- Movement – especially twisting or bending – pulls at the edges
- Hot skin and rising body temp can reduce stick
- Clothes rub or catch on the device
- Wiping down mid-session can tug at the patch
Your Dexcom G7 or G6 is designed to last – but not necessarily through intense workouts without a bit of backup. And once that sensor lifts or loosens, your readings may become unreliable.
What a Dexcom Patch Really Does
Think of a CGM patch (or, overpatch) as a seatbelt for your sensor. A Dexcom patch acts like a protective cover, holding your device in place even when things get sweaty or intense.
Here’s how it helps during active days:
|
Workout Worry |
What an Overpatch Does |
|
Edges peeling during squats |
Flexible tape moves with your body |
|
Sweat breaking the seal |
Breathable material stays secure |
|
Sensor catching on clothing |
Smooth outer layer shields it |
|
Focus slipping mid-session |
Less worry = more freedom to train |
You won’t even notice it’s there once it’s on. But you will notice when it’s not – especially if your sensor ends up on the locker room floor.
Choosing the Right Patch for Active Wear
There are loads of patches out there, but not all of them are designed with movement in mind. If you're active, look for these must-haves:
- Breathable material to let sweat evaporate
- Flexible fit that stretches with your skin
- Strong adhesive that won’t lift at the corners
- Hypoallergenic glue (especially if your skin flares up easily)
- A cut that matches your CGM model – no more trimming to size
The Dexcom G7 Patches – 20 Pack ticks every one of those boxes. They’re designed to stay put for 10+ days and feel comfortable enough that you’ll forget you’re even wearing one.
Using the G6? Our Dexcom G6 Patches offer the same reliable hold, built with workouts in mind.
Smart Tips to Keep Your Sensor Secure During Exercise
You’ve got the patch – now get the most out of it:
- Always clean the site first – alcohol wipes are your friend
- Avoid lotion or oil where the sensor’s going
- Give it a few hours to set before getting sweaty – 12 hours is ideal
- Hold firm pressure after applying to help the adhesive grip
- Warm it up in your hands first – it sticks better that way
- Rotate your sites if you're working out often
If you’re in a humid climate or working out daily, you might go through patches faster – totally normal. That’s why having a few extras on hand is smart.
Got Sensitive Skin?
If you’re someone who breaks out in hives just looking at a sticker, you’re not alone. Skin reactions are a big deal when it comes to adhesives.
The good news? Our patches use skin-safe adhesive and are latex-free, so they’re made to be gentle. Still, we always recommend doing a small patch test if you’ve had issues before.

Why It Matters for Performance and Peace of Mind
When your CGM stays stuck, you get uninterrupted data – no signal dropouts, no false lows, and no second-guessing your decisions. It’s not just about comfort. It’s about keeping your health tech working properly while you’re doing what you love.
Whether you’re weightlifting, walking, running, or hiking, your overpatch gives you one less thing to worry about – and that’s worth it.
Final Thought: Sweat It Out Without Stress
You don’t need to stop moving to protect your sensor – you just need the right patch to move with you.
Our Dexcom G7 Patches are ready for it all – high temps, long sessions, and everything in between. Give your CGM the staying power it deserves.
