Beyond Type 1’s Continuous Glucose Monitor— ‘CGM’ —Chart


Continuous glucose monitors (CGMs) have completely changed the way diabetes is managed. For example, CGMs:

CGM Basics

  • Made Up of Three Parts: The majority of CGMs consist of:
    • A receiver used to gather blood-sugar data, though your smartphone can work just as well
    • A transmitter, which is placed above the skin
    • A sensor that is inserted into the skin.
  • Easily Applied: Typically, the easy-to-use applicator that comes with the device is used to install CGMs.
  • Waterproof: Most CGMs are safe for use in showers and while swimming.
  • Have Alarms: Some can alert you if your blood glucose levels are low or high.

Which CGM is Right for Me?

Here are some questions to think about when considering your CGM options:

  • Will my insurance cover CGMs?
  • How often will I have to change the sensors?
  • Will I need to purchase a handheld reader, or is the device compatible with my smartphone?
  • Do I want a CGM to connect to my insulin pump?

With the help of this CGM chart (see below), we can answer all of your questions.
