FAQs

What is a CGM?

A CGM is a small wearable device, called a continuous glucose monitor, that tracks glucose levels continuously. Some CGM’s display the data periodically after swiping with a reader or smartphone, while other devices display the data continuously. Many CGM units allow you to set alerts for highs and lows to assist with managing your glucose levels.

 

Is a CGM different from traditional blood glucose monitoring (BGM)?

Yes, a traditional BGM measures the glucose in your capillary vessels, whereas a CGM measures the glucose in the fluid around your cells (interstitial fluid). Glucose in your blood rises and falls faster than glucose in your interstitial fluid. A BGM is a check of your blood sugar at one point in time (when you stick your finger) where a CGM monitors levels continuously and records them every 1–5 minutes (dependent on your specific device).

 

How does a CGM work?

There are three parts to a CGM: the sensor, the transmitter, and the viewing device (receiver or smartphone). The sensor is applied to the skin (usually the back of the arm or the abdomen) and contains a thin filament that goes through the skin into the interstitial fluid, where the glucose level is measured. The transmitter attaches to the sensor and wirelessly sends the glucose readings to a receiver or smartphone. Some CGMs have the transmitter and sensor as one piece, while others have them separate. Similarly, some require a receiver, while others allow the use of a smartphone app for viewing glucose readings.  

 

Am I a good candidate for CGM?

CGM devices provide useful information for managing diabetes by allowing access to real time trends in blood sugar level changes. Access to these trends can assist in taking preventive measures against hypoglycemia and hyperglycemia.  Any person who has diabetes and relies on insulin for treatment or who has a history of problematic low blood sugar (hypoglycemia) could be a good candidate for a CGM.

 

I’m experiencing skin irritation from my CGM adhesive, what can I do?

Follow these steps to prevent skin reactions and to promote skin health:

  • Clean your skin with an antimicrobial soap and dry thoroughly. You may also find it helpful to gently exfoliate your skin and trim hair around the sensor.
  • Choose a site with enough fat to “pinch” up and avoid areas with broken skin, such as cuts and scabs.
  • Do not use any oils or lotions around the sensor site.
  • Do not insert directly after a bath/shower, and try to minimize humidity when inserting the sensor.
  • Rotate your sensor site and avoid using the same site twice in a row.
  • Keep your skin healthy by moisturizing your skin between sensor use, but avoid using moisturizer at the site on the day that you insert your sensor.

 

How do I keep my patch from peeling off?

Make sure to follow the insertion instructions and use the overpatch to keep the sensor in place. Make sure you are following these steps:

  1. Sensor site should be clean, flat, and completely dry.
  2. Choose a sensor site that has some fat under the skin.
  3. Put additional adhesive on the patch before applying the overpatch.
