Risks and Benefits
When using any medical device, there are risks and benefits. In this chapter, you'll learn what
they are, helping you decide if Dexcom's G5 Mobile CGM System is right for you.
First, let's review some possible risks.

3.1 Risks

There are some risks with using real-time CGM.
Not Receiving Alarm/Alerts
If you aren't getting your CGM Alarm/Alerts, you run the risk of not knowing you are having a
severe glucose low or high.
Some hardware issues preventing Alarm/Alerts:
• Alert function is turned off
• Transmitter and display device is out of range
• Receiver or smart device isn't showing sensor glucose readings
• Receiver or smart device battery is dead
• Unable to hear Alarm/Alerts or feel vibration
• App not running in the background
• Smart device is in Do Not Disturb
See Troubleshooting or recommended settings in Chapter 11 for more information.
Sensor Glucose Reading Different From Meter's
The sensor glucose reading can be different than your meter's BG value.
If the sensor's glucose reading is higher than your meter's BG value, you may miss a Low
Alert. As an example, your last sensor's glucose reading was 82 mg/dL, whereas your BG
value shows 78 mg/dL. If your Low Alert is set at 80 mg/dL, you won't receive an Alert
because the sensor glucose reading is 82 mg/dL.
