From the Guidelines
You should remove your Dexcom continuous glucose monitoring system before having an X-ray. Although the provided evidence does not directly address the removal of Dexcom devices before X-rays, it does mention that glucose monitoring devices should be removed for certain procedures, with each company having their own list, such as MRI and diathermy 1. Given the potential for electronic devices to be damaged by radiation or interfere with the quality of the X-ray image, it is reasonable to err on the side of caution. Before your appointment, inform the radiologist or technician that you use a Dexcom CGM so they can advise you on proper removal and temporary storage during the procedure. Some key points to consider:
- The Dexcom device contains electronic components that could potentially be damaged by X-ray radiation or might interfere with the quality of the X-ray image.
- During the time your Dexcom is removed, you should monitor your blood glucose using a traditional fingerstick meter if needed.
- After the X-ray is completed, you can reapply your Dexcom sensor, though you may need to insert a new sensor if the adhesive no longer sticks properly. It is essential to prioritize caution when it comes to medical devices and radiation, as the potential risks associated with not removing the device may outweigh any benefits of leaving it in place 1.
From the Research
Removal of Dexcom 6 Before an X-Ray
- The Dexcom G6 continuous glucose monitoring system has been tested for safety and functional integrity after simulated radiologic procedures, including x-rays 2.
- The study found that the wearable components of the G6 CGM System retain basic functionality and data integrity after exposure to simulated therapeutic and diagnostic radiologic procedures, including x-irradiation used in typical imaging studies.
- The devices are unlikely to be affected by x-irradiation used in typical imaging studies, suggesting that removal of the Dexcom 6 before an X-ray may not be necessary.
- However, it is essential to consult with a healthcare professional or the device manufacturer for specific guidance on the use of the Dexcom 6 during X-ray procedures.
Key Findings
- The Dexcom G6 CGM system has been shown to be accurate and safe in various studies, including those involving pregnant women with diabetes 3 and adults with diabetes 4.
- The device has also been tested for safety in hyperbaric environments 5 and during cardiac surgery 6.
- While these studies provide valuable information on the safety and accuracy of the Dexcom G6 CGM system, they may not directly address the specific question of removal before an X-ray.
Considerations
- It is crucial to follow the manufacturer's guidelines and consult with a healthcare professional for specific advice on the use of the Dexcom 6 during X-ray procedures.
- The decision to remove the Dexcom 6 before an X-ray should be based on individual circumstances and the specific requirements of the X-ray procedure.
