Swimming with a CGM (Glucose Sensor) or Insulin Pump: Comfort & Secure Wear Guide
Swimming is great — until your device starts lifting, snagging, or slipping.
Chlorine, saltwater, heat and friction can make a CGM or pod feel less secure. This mobile-first guide helps you spot the main issue and choose a simple, reusable solution to hold and secure your device — without overloading the page.
My CGM or pod feels less secure in water: add a “second-skin” layer
Water + movement can increase friction and small snags (towel, swimsuit, backpack straps). The goal is to add mechanical hold on top of your sensor/pod — without relying only on extra tape.
First try: Dia-Band (reusable protective armband)
- Holds and helps protect your CGM or pod on the upper arm during swimming and beach days.
- Soft armband that wears like a light sleeve over the device (no “strap” feeling).
- Helpful if you feel your sensor catches on towels or clothing when you move.
Note: an armband helps with hold and protection, but it does not change your device’s waterproof rating. Always follow your device manufacturer’s guidance.
I want adjustable hold during active swimming (laps, waves, kids, sports)
If you want to tighten or loosen the fit depending on activity level, an adjustable option can feel more reassuring — especially when you transition from warm-up to higher intensity.
Adjustable option: Dia-Style (adjust as you move)
- Adjustable fit so you can fine-tune the hold during activity for better stability.
- Not the lightest option — but the adjustability can be a real advantage when you want extra hold.
- Popular for sports + swim days when you don’t want to think about your device.
I need extra adhesion (optional): patches for CGM & pods
Some people like combining a protective armband with an adhesive patch — especially for long pool sessions, beach days, or if they know their edges lift easily.
Optional: Patch Me Up (adhesive patches)
- Extra help to support edges and reduce early lifting.
- Great if you want a low-profile option under an armband.
- Pick the patch type and size that matches your device and skin preferences.
Swimming with an insulin pump with tubing: keep it safe before/after water
With an insulin pump with tubing, water handling depends on your pump model (water resistance, disconnect rules, etc.). Always follow your manufacturer’s instructions and your care team’s advice.
Quick practical idea
- If your pump should stay out of water, plan a secure routine for before/after the swim (changing, towels, poolside).
- Keep tubing calm and close to the body when moving around lockers and bags.
- Heat can be part of swim days — consider temperature-aware solutions when you’re outdoors for long periods.
