Can I Get My Dexcom Sensor Wet? (Showering, Bathing, and Swimming)

Dexcom G7 and D1+ CGM systems are water-proof for up to 24 hours and can be worn while bathing, showering and swimming1,2 and have been tested to a depth of up to 2.4 metres (8 feet) for a duration of up to 24 hours*.

The receiver if you have one should always be kept dry.

Key points:

Swimming and Water Activities:

• If you are swimming, keep your display device (phone or receiver) closer than normal to the sensor for best results, as Bluetooth signals do not travel well through water.

• You may not receive real-time readings or alerts while your device is out of range or underwater, but your Dexcom device will continue to collect data and transmit it when you are back in range.

• Saunas and steam rooms may exceed the maximum operational temperature (42oC) and humidity (90%). Regular exposure to heat may also reduce the effectiveness of the adhesive.

Patch Care:

• For best adhesion, keep the patch dry and sweat-free for the first 12 hours after insertion.

• If the patch starts to peel, use an over patch or medical tape.

After Water Exposure:

• Gently pat the patch dry after swimming or bathing.

• If exposed to sea / river water rinse with cold water and then pat dry

• If the patch becomes loose, trim the edges and secure with medical tape or an over patch. Alternatively use a medical adhesive to stick the edges back down. See our Adhesion best practice FAQ.
