Dexcom CGM and readings on a smart device

Dexcom technology is more accessible than ever before

NICE (The National Institute for Health and Care Excellence) have guidelines on funding real-time continuous glucose monitoring (CGM) for people with diabetes.
  • NICE now recommends that people with type 1 diabetes are offered a choice of a glucose sensor, including real-time CGM.1
  • Children and young people with type 1 diabetes should be offered real-time CGM.2
  • For people with type 2 diabetes, the recommendation is that real-time CGM can be considered an alternative to intermittent scanning (isCGM).3
  • NICE now recommends hybrid closed loop (HCL) systems as an effective option for managing blood glucose levels in type 1 diabetes.4

'As a parent of a child with Type 1, you have to learn to be flexible. There were so many times, especially when she was first diagnosed, when it felt like our lives had to fit around Ava’s disease…not the other way around. When we got on the Dexcom CGM System, it was like the weight was lifted. We finally have a tool to help us get more control.'
