What are the benefits of continuous glucose monitoring (CGM)?

Some continuous glucose monitoring (CGM) system offers individuals with type 1 or type 2 diabetes around-the-clock glucose readings with fewer fingersticks--or, depending on the CGM product you choose, none at all.*† This level of timely feedback can help users make more informed treatment decisions that may help reduce their A1C levels.1
Whether you treat your diabetes with multiple daily injections or an insulin pump, you can expect wide-ranging health and convenience benefits from using a CGM device. The benefits of using Dexcom CGM system include the following:
  • More insight than monitoring alone
Unlike a single reading from a blood glucose meter, a CGM provides real-time, dynamic information about the speed and direction (trending higher or lower) of your glucose levels.
  • Improved glycemic control
Having continuous feedback on diet, exercise, and insulin requirements from a CGM can help you make more informed treatment decisions. This awareness can lead to tighter glycemic control than using a blood glucose meter alone.2
  • Fast, proactive response
CGM systems take glucose readings every few minutes and allow you to set customizable thresholds with alerts when your readings are out of target range. This means you’ll often know that you are out of range before you begin to feel symptoms, and you can proactively respond.
  • Fewer fingersticks
CGM devices use tiny sensors to measure glucose levels just beneath the skin. These sensors connect to a transmitter, which wirelessly transmits readings to a receiver or a compatible smart device. At any time, you can see your reading with just a glance.
  • Fewer worries
