Dexcom One is a continuous glucose monitoring (CGM) system made by Dexcom . It is a device that helps people with diabetes track their blood sugar levels throughout the day and night. Unlike traditional blood glucose meters, which require finger pricking to get a blood sample, Dexcom One uses a small sensor that is inserted under the skin. The sensor measures glucose levels in the interstitial fluid (the fluid between cells) and sends the data wirelessly to a receiver or a smartphone app.
