Get alerts to help you spend more time in range

Customisable alerts let you know whenever your glucose falls outside of your pre-set high and low glucose levels, so you can take action.
Sometimes you can have readings that trend higher after meals. Dexcom One’s Delay 1st Alert feature means you can choose after how much time want to be alerted for high glucose, helping reduce alarm fatigue.​
