I need a CGM - Which one should I buy?

There are many CGM's on the market and you do NOT need a Doctor's prescription any longer to purchase one. They are generally accurate to within +/- 20mg/dL. (Read my article on CGM accuracy here.)

Over-the-counter sensors

There are currently two over-the-counter sensors, these are:

  • Stelo by Dexcom - More focused on Diabetes management
  • Lingo by Abbott Labs - More focused on wellness.

These are perfectly fine to use and help you with glucose control and optimization.

Prescription sensors

There are also sensors that you can use with a prescription. These are more accurate (+/- 10mg/dL) and sensitive to changes in glucose.

These are:

  • Freestyle Libre 3 plus by Abbott Labs
  • G7 by Dexcom
