Do the Pros of a CGM Outweigh the Cons? Advice for Newbies

If you’re feeling unsure about getting started with a continuous glucose monitor (CGM), you’re not alone! Building trust in a new diabetes device can take time, and the transition is often a journey, not just a switch.

Beyond Type 1 spoke with members of the Dexcom Warrior community—Dexcom’s ambassador program—to explore the ups and downs of making this change. If you’re in the same boat, this breakdown will help you weigh the pros and cons.

Why Wouldn’t Someone with Diabetes Wear a CGM?

Although CGMs are a useful tool for many people with diabetes, there are several common reasons why someone might choose not to or be unable to wear one. Here are some of the most frequently reported reasons from members of the diabetes community for not using a CGM:

• Discomfort with Showing Diabetes Devices: Not everyone with diabetes is eager to show it. Some people might feel this way because they’ve had negative experiences with misconceptions about diabetes or faced cultural stigma. Feeling comfortable with this is a personal journey that takes time.
• Physical Discomfort: Some people experience skin irritation or discomfort when wearing a CGM, often due to the sticky adhesives that help it stay in place longer.
• Cost Concerns: CGMs can be costly, and despite efforts by diabetes organizations, insurance gaps still exist, making CGMs hard to budget for.
• Constant Attachment: Diabetes devices serve as a constant reminder that diabetes requires 24/7 attention; alarms help manage blood sugar, but can also get annoying.
• Building Trust: Switching from a blood glucose meter (BGM) to a CGM can feel overwhelming, and trusting a new device to essentially support your survival with diabetes takes time and relationship-building.

Why CGMs Are Helpful to Most People with Diabetes

While there are some understandable frustrations with CGMs, thankfully, the benefits usually outweigh the drawbacks for people in the diabetes community. Using a CGM can empower you to improve your diabetes management, making the journey easier.

To address some of these challenges, users of devices like the Dexcom G7 can:

• Set glucose alerts to vibrate, so you can conveniently pause your CGM alerts whenever needed.
• Use skin barriers or wipes to minimize the effects of sticky CGM adhesives, which can leave residue or be uncomfortable to remove.
• Explore savings programs to help reduce or cover the cost of your CGM.
• Rotate where you place your CGM regularly to prevent redness or dryness around the insertion area.
• Join ambassador programs, like the Dexcom Warriors community, to get inspired by others confidently showing off their devices.

Hesitant to Try a CGM? Most People Are!

Dexcom Warrior, Dante V., who lives with type 1 diabetes (T1D), relates to the ups and downs of using a CGM.

“I was timid but curious starting out,” Dante shared. “The idea of having something attached to my body felt a bit off-putting at first. I’m the kind of person who doesn’t love wearing extra devices, so the thought of a CGM was a little intimidating.”

Dante’s active lifestyle pushed him to pursue it anyway.

“I’ve always been into sports, so I figured it could help me understand my body better,” he said. “Especially with how food, stress or exercise might impact my glucose levels.”

Dante uses the Dexcom G7, which includes a handful of helpful features like:

• Real-time blood glucose alerts: The Dexcom G7 app provides a glucose reading at least every five minutes.
• Customizable alert settings: You can customize your settings to get alerts for different glucose  events, choosing the sounds and times you’d like to be notified about your glucose readings..
• Clarity app data: This displays your real time glucose tracing and time-in-range (TIR), helping you identify patterns in your diabetes management.
• Blood glucose graph: You can view trends in your blood sugar levels over a 3-, 6-, 12-, or 24-hour period.
• App connections: The Dexcom G7 app allows you to connect with various health apps to gain a broader view of your overall well-being.

Being Present with T1D

Since beginning his journey with a Dexcom CGM, Dante has adjusted how he manages his daily diabetes routine. The biggest change? His intentionality.

“I’m much more intentional about fueling before coaching or workouts, and I’ve become more mindful of how I structure my meals to avoid big swings,” Dante said. “It’s been a game-changer in terms of feeling more balanced and in control. Another tip: reach out to existing Dexcom Warriors. Whether it’s someone you know personally or someone in a community online, it really helps to hear firsthand what their experience was like. I found it encouraging to hear how others made it work and how it improved their daily lives.”

Using data from a CGM might seem overwhelming at first, but it can help people with diabetes (PWD) make more proactive management choices and foster habits that simplify life with diabetes.

Dante’s Advice for Newbies: “Take the chance.”

For anyone thinking about using a CGM who feels hesitant or faces obstacles, Dante offers some helpful advice.

“If you’re facing hurdles getting started with a CGM, one of the biggest things that helped me was having an open conversation with my doctor,” he shared. “Don’t be afraid to ask questions or express your concerns, especially if you’re unsure whether it’s the right fit.”

“Take the chance,” Dante said. “I totally get how intimidating it can be to try something new, especially something that’s attached to your body, but honestly, it’s worth it. A Dexcom CGM is designed to help you thrive, not just manage.”
