Continuous Glucose Monitoring (CGM) 101: Get the Facts

If you’ve been diagnosed with type 2 diabetes, you have had to learn a whole new vocabulary — A1C, blood sugar, glucose, insulin, test strips, and more. You may have even heard the term continuous glucose monitor, or CGM.

Even if you’re familiar with the term, you might now know exactly what it is. We’re here to help.

What is a Continuous Glucose Monitor?

A continuous glucose monitor, or CGM for short, is a compact medical device that monitors your glucose levels every five minutes.  It can be a really powerful tool for people with type 2 diabetes because you can see how food, sleep, stress and movement affect your glucose levels – without fingersticks, guesswork, or frequent doctor visits.

How do CGMs work?

To use a CGM, you insert a small sensor onto a spot on your body, such as your stomach. A miniscule cannula, almost like a tiny straw, inserts under the skin. Adhesive holds the sensor in place, usually for a period of up to 10 days. When inserted, the sensor takes glucose readings from fluid in the skin (called interstitial fluid).

A small, reusable transmitter attaches to the sensor to wirelessly transmit your glucose reading to a receiver. For many CGM systems, your smart phone acts as the receiver. This makes it easy to use — checking your blood sugar is as simple as opening an app on your phone.

CGMs are virtually painless to apply, discreet, and are water-resistant.  You can shower and work out without issue.

CGMs are game-changers

Continuous glucose monitoring is empowering. It’s been said that fingersticks are like seeing a photograph and a CGM is like watching the movie. With the movie, you get the full story of your diabetes each day. And the story of your glucose levels is likely far more interesting and informative than you’d expect.

For example, you may see that the ‘healthy’ snack you’ve been eating is actually causing a big glucose spike. You might notice that stress causes spikes and a good night’s sleep contributes to steady glucose levels. Maybe that walk you’ve been adding to your morning routine is really making a difference.

It can be informative to see what’s leading to spikes and rewarding to see what’s keeping you steady. In fact, studies show that the act of wearing a CGM alone can help people with type 2 diabetes lower their A1C. It also helps people obtain optimal Time in Range.

In other words, with a CGM, you can see that small changes you’re making for your health are having a big impact.
