Continuous glucose monitors (CGMs) have transformed the way we live with type 1 diabetes. They give us access to real-time glucose data, trend arrows, alerts, and insights that were unimaginable just a few years ago.
But there's a side of CGM use that doesn't get talked about enough.
For some people, this constant stream of diabetes data doesn't create peace of mind. It creates anxiety.
I've worked with hundreds of adults living with type 1 diabetes, and there's a pattern I see again and again. Instead of feeling more confident after starting a CGM, they find themselves looking at their phone every few minutes, reacting to every blood sugar fluctuation, and feeling like diabetes is taking up more mental space, not less.
The problem isn't the technology.
The problem is that more information doesn't automatically create more confidence. Without the psychological skills to respond to uncertainty, more information often leads to more anxiety.
The Anxiety Feedback Loop
Imagine you're sitting at your desk working. You glance at your phone and see your blood sugar has drifted from 118 mg/dL to 132 mg/dL.
Ten minutes later, you check again. Now you're 146 mg/dL with a diagonal arrow up.
Your mind immediately starts racing.
Should I correct? Should I wait? Did I miscount lunch? Did I not take enough insulin?
A few minutes later, you check again. Before you know it, you've spent the last 30 minutes thinking about your blood sugar, even though it's been in range the entire time.
This is how people become trapped in an anxiety feedback loop.
You feel anxious about your blood sugar, so you check your CGM. Looking at the number gives you a brief sense of relief. That relief teaches your brain that checking reduces anxiety. So the next time you feel anxious, you check again.
Over time, this becomes automatic.
You're no longer looking at your CGM because you need information. You're looking because you've trained your brain to use checking as a way to manage anxiety.
The problem is that the relief only lasts for a moment. Before long, the uncertainty returns, and so does the urge to check. The cycle repeats itself all day long.
The Answer Isn't Less Data. It's Better Boundaries.
The way to break this cycle isn't to stop using your CGM. It's to create healthier boundaries with it.
Boundaries are the key to any healthy relationship, including your relationship with your CGM.
That may sound strange at first. After all, isn't the whole point of having a CGM to look at it?
Yes, but there's a difference between using your CGM as a tool and allowing it to become the center of your attention all day long.
Five Boundaries That Can Reduce CGM Anxiety
1. Check your CGM with intention, not out of habit.
Before you look at your phone, ask yourself one simple question: Why am I checking right now?
If the answer is because you're about to eat, exercise, drive, or respond to an alert, that's intentional. If the answer is, "I just want to make sure everything is okay," you're probably looking for reassurance rather than information.
2. Remember that not every number requires action.
Blood sugars naturally fluctuate. Many people start treating every small rise or fall as a problem that needs to be fixed immediately. Learning to tolerate normal glucose fluctuations is one of the most important psychological skills you can develop.
3. Make your alerts work for you, not against you.
Alerts are one of the greatest safety features of CGMs. They can also keep your nervous system in a constant state of vigilance if they're set too aggressively. Work with your healthcare team to make sure your alerts support your goals instead of constantly pulling your attention back to diabetes.
4. Give yourself permission not to look.
If your CGM isn't alerting you and you're not making a diabetes decision, you don't need to know your glucose every five minutes. Choosing not to check becomes an opportunity to build trust, both in your CGM and in yourself.
5. Don't let your CGM decide how you live your life.
This is the most important boundary. I've seen people cancel walks because of a trend arrow, say no to dinner invitations because their blood sugar was running a little high, and avoid playing with their kids because they were worried about what might happen.
Your CGM should inform your decisions. It should never make them for you.
Psychological Diabetes Care Can Help
CGMs have transformed the way we manage type 1 diabetes.
But they haven't solved the psychological challenges of living with diabetes.
A CGM can tell you what your blood sugar is and can even predict where it's going. It can't teach you how to tolerate uncertainty, resist the urge to seek reassurance, or stop fear from driving your decisions.
Those are psychological skills.
The problem is that diabetes education teaches you how to manage your blood sugar. It doesn’t teach you how to manage the stress of living with diabetes.
That's the gap Psychological Diabetes Care is designed to fill.
Psychological Diabetes Care is the missing half of diabetes care. It teaches psychological skills, such as boundaries, that you need to respond effectively to fear, uncertainty, frustration so those emotions no longer dictate your behavior or consume your life.
That's why I wrote LiveFree with T1D - a free, digital resource designed to fill that gap.
The book introduces the principles of Psychological Diabetes Care and gives you practical, evidence-based tools to respond to the stress of T1D so you can live life on your own terms.
