The Benefits of Wearing a CGM

If you’ve been keeping up with the latest advancements in wearable tech, you may have heard about continuous glucose monitors (CGMs). CGMs are small devices that are worn on the body and continuously monitor your blood sugar levels. They are typically used by people with diabetes, but an increasing number of non-diabetics are starting to wear them as well. So, what are the benefits of wearing a CGM?

There are a few key benefits of wearing a CGM, even if you don’t have diabetes. First, CGMs can help you better understand your body and how it responds to different foods and activities. If you’re struggling to lose weight or regulate your energy levels, a CGM can give you valuable insights into which foods work best for your body and when you should be active. Additionally, CGMs can help reduce anxiety by giving you a more complete picture of your health. For example, if you have a headache, you’ll be able to see if your blood sugar is low or if dehydration is the culprit. Finally, CGMs can help improve your sleep quality by allowing you to track your blood sugar levels overnight.

How Do CGMs Work?

CGMs work by measuring the amount of glucose in your interstitial fluid, which is the fluid that surrounds your cells. A small sensor is inserted just under the skin, usually on the arm or abdomen. The sensor stays in place for several days or weeks before it needs to be replaced. A transmitter sends data from the sensor to a receiver, which displays your blood sugar readings in real-time. You can also view historical data on the receiver or on a smartphone app.

CGM Brands

There are a few different brands of CGMs on the market today. The most popular brand is probably Dexcom, which offers both FDA-approved and non-FDA-approved options. There are also several brands that sell only non-FDA-approved options, such as Eversense and Freestyle Librelink Up. Non-FDA-approved CGMs may not be as accurate as FDA-approved models, but they tend to be much cheaper.


Overall, there are many potential benefits of wearing a CGM, even if you don’t have diabetes. If you’re looking for a way to improve your health and well-being, a CGM could be a good option for you. Just be sure to do your research and choose a reputable brand so that you can be sure you’re getting an accurate device.
