About Dexcom

Founded in 1999, Dexcom is to help people control diabetes. Dexcom provides continuous blood glucose monitoring to help discover intelligent, simple continuous blood glucose monitoring. Its purpose is to help diabetics easily track their blood sugar levels. The G5 Mobile is the world's first real-time continuous blood glucose monitoring (CGM) system approved for adults and children over 2 years of age. The G5 Mobile uses Bluetooth technology built into the transmitter to enable complete remote viewing of blood glucose levels, trends and data from compatible smart devices. With the G5 mobile CGM system, when your head is too high or too low, your compatible smart device will directly issue an alarm. Alarms and alarm sounds can also be customized for text message display, allowing additional caution and privacy.
