Vively is designed for non-medical, wellness use, but there are certain situations where wearing a CGM may result in inaccurate readings or where the sensor should be temporarily removed.
Medical imaging and procedures
You should remove your CGM sensor before undergoing medical procedures that involve strong magnetic or electromagnetic fields, including:
MRI scans
CT scans
X-rays
You can apply a new sensor after the procedure is complete.
Medications and supplements
Some medications and supplements may interfere with CGM readings.
High doses of vitamin C may cause falsely elevated glucose readings
Certain medications may affect glucose levels or sensor accuracy
If you’re unsure whether a medication or supplement could interfere with CGM readings, it’s best to:
Confirm readings with a finger-prick test if they don’t match how you feel
Check manufacturer guidance or speak with your healthcare provider
Heat, cold, and extreme environments
CGMs are designed to operate within normal everyday temperature ranges.
Exposure to extreme heat or cold — such as:
Saunas
Steam rooms
Ice baths
Cryotherapy
may temporarily affect sensor performance and result in inaccurate readings.
We do not recommend cryotherapy while wearing a CGM sensor.
Adhesive sensitivities
CGM sensors and protective patches use medical-grade adhesives similar to those used in bandages.
If you:
Have sensitive skin
Have known adhesive allergies
Experience itching, redness, or irritation
remove the sensor and seek advice before applying another.
Important reminder
CGMs measure glucose in interstitial fluid, not directly in the blood.
If readings don’t match how you feel, always confirm with a finger-prick blood glucose test.
In summary
Remove CGMs for MRI, CT, or X-ray procedures
Some medications and supplements may affect readings
Extreme heat or cold can temporarily reduce accuracy
Adhesive reactions can occur in sensitive individuals
