Introduction: A New Era in Diabetes Care

Managing diabetes is a daily challenge. People with diabetes have to keep a close eye on their blood sugar to stay healthy and feel their best. But guess what? There’s some exciting news in the world of diabetes care! The U.S. Food and Drug Administration (FDA) just approved the new Dexcom G7 Continuous Glucose Monitor (CGM) with a 15-day wear time. That means you can wear it longer, track your blood sugar more easily, and take control of your health like never before.

In this blog, we’ll break down what this new Dexcom G7 15-Day system means for you, how it works, and why it might make your life a whole lot easier.

What Is a Continuous Glucose Monitor (CGM)?

Let’s start with the basics. A CGM is a small device that checks your blood sugar (also called glucose) all day and night. You don’t have to poke your finger each time you want to check your sugar. Instead, a tiny sensor sits just under your skin and measures the glucose in your body.

The Dexcom G7 sends the glucose numbers to your phone or a small reader. You can see your blood sugar anytime, anywhere. It also gives alerts if your sugar gets too high or too low.

What’s New About the Dexcom G7 15-Day?

The G7 isn’t brand new—but the 15-day version is! Until now, people using the G7 had to change their sensors every 10 days. Now, with this update, the sensor lasts 15 full days—that’s 5 more days of freedom between changes!

Here’s what’s new and exciting:

• Longer wear time: Fewer sensor changes every month (only two!).
• Smaller, sleeker design: The sensor is tiny and more comfortable to wear.
• Faster warm-up: It only takes 30 minutes to start working.
• More accurate readings: The G7 gives even better results.
• Built-in sensor and transmitter: Easier to use, with fewer parts to worry about.
• Great for people on the go: It works with your smartphone and gives alerts when you need them.

Why Longer Wear Time Matters

Let’s be real—changing a sensor every 10 days can be a pain. It takes time and planning, and sometimes, you just forget. That’s why a 15-day sensor can make a big difference.

With 15-day wear, you get:

• Less hassle: Fewer reminders to switch out your sensor.
• Fewer costs: Depending on your insurance, you may save money by using fewer sensors.
• More freedom: Travel, work, and live without thinking about sensor change days so often.

Who Can Use the Dexcom G7 15-Day CGM?

Right now, the new 15-day version is approved for adults with diabetes. That includes people with Type 1 or Type 2 diabetes. It’s not yet approved for children or teens, but that could change in the future.

If you’re already using Dexcom G7, talk to your doctor about switching to the 15-day model. If you’re using a different CGM or still doing finger sticks, this could be a great time to try something new!

How to Use the Dexcom G7 15-Day Sensor

Using the G7 is simple. Here’s how it works:

1. Apply the sensor to your upper arm using the built-in applicator.
2. Wait 30 minutes for the warm-up.
3. Start seeing your blood sugar on your phone or reader.
4. Get alerts when your sugar is high or low.
5. Change the sensor every 15 days.

It’s that easy. You don’t need to calibrate it with finger sticks (though your doctor might still recommend checking with a meter sometimes).

Why the Dexcom G7 is Loved by Users

Lots of people already love the Dexcom G7. With the 15-day sensor, it’s even better. Here’s what users say:
- “I love seeing my sugar without having to test.”
- “The alerts save me from dangerous lows while I sleep.”
- “It helps me understand what food and exercise do to my numbers.”
- “15 days is amazing! I don’t have to think about changing it all the time.”

How Does It Help with Diabetes Management?

Managing blood sugar is hard work. The G7 helps by giving you more information. You can see what happens after you eat, exercise, or take insulin. That means you can make better choices and avoid problems.

You’ll also feel more confident knowing you’ll get an alert before things get dangerous. No more guessing if you’re too low or too high.

What About the App and Smart Devices?

The Dexcom G7 works with both iPhones and Android phones. It also connects with some smartwatches. You can see your sugar number and trend arrows (telling you if your sugar is going up or down) right on your wrist or screen.

The app also lets you share your numbers with family or friends—perfect for caregivers or loved ones who want to help keep you safe.

Does It Replace Finger Sticks?

Most of the time, yes! You don’t need to check your sugar with a finger stick when using the G7. But in some cases—like fast-changing numbers or if you feel different than your reading—you might still want to double-check.

Your doctor will help you decide what’s best for you.

Insurance and Cost: Is It Covered?

Most insurance plans, including Medicare, cover CGMs like the Dexcom G7. The new 15-day version should be covered the same way the 10-day version is.

If you’re not sure, check with your insurance provider or ask your doctor’s office to help. There are also savings programs on the Dexcom website.
