Managing diabetes requires precision, consistency, and the right tools to maintain blood glucose levels within a healthy range. For many, continuous glucose monitoring (CGM) systems and insulin pumps have become indispensable in diabetes management, offering more accurate, real-time insights and better overall control. But how do you choose the right one for your needs?
In this article, we’ll discuss two popular options for managing diabetes: Freestyle Libre, a standalone CGM system, and insulin pumps with an integrated CGM (such as Medtronic and Tandem). Both offer unique benefits, but understanding their key features and differences will help you decide which one best fits your lifestyle and diabetes management needs.
Before we continue, At Type Strong, we support individuals with diabetes by providing innovative products like our FreeStyle Libre, Medtronic Guardian & Dexcom G7 adhesive patches and our new Tape roll. Choose the best CGM for your needs and enhance your experience with our high-quality adhesive patches today!
What is the Freestyle Libre?
The Freestyle Libre is a continuous glucose monitoring (CGM) system that provides real-time glucose data without the need for finger sticks. It consists of a small sensor that is applied to the back of the upper arm, which continuously monitors glucose levels in the interstitial fluid (the fluid between your cells). Users can check their glucose levels by simply scanning the sensor with a reader or smartphone app.
Key Features:
- No Calibration Required: One of the standout features of the Freestyle Libre is that it does not require calibration with fingerstick blood glucose readings. This makes it an easy, hassle-free option for users.
- Long Sensor Lifespan: The sensors can last up to 14 days, allowing for longer wear time compared to some other CGMs.
- Affordable Cost: The Freestyle Libre is a cost-effective option compared to other CGM systems, making it an appealing choice for those who need real-time glucose monitoring without the higher price tag.
Ideal for: The Freestyle Libre is ideal for those seeking a simple, affordable solution for continuous glucose monitoring. It's a great option for individuals who want to monitor their glucose levels without the complexity of insulin pumps or frequent calibrations.
What are Insulin Pumps with Integrated CGM's?
An insulin pump can work in conjunction with certain CGM's, to delivery insulin when required. Popular systems like Medtronic and Tandem provide continuous, real-time glucose monitoring, along with insulin pumps that deliver basal and bolus insulin automatically or based on user input.
Key Features:
- Continuous Insulin Delivery: Insulin pumps provide a continuous basal insulin dose, helping maintain stable blood glucose levels throughout the day. They also allow for bolus doses at mealtime based on glucose levels, carbohydrates, and personal needs.
- Real-Time Glucose Monitoring: CGM systems offer continuous glucose monitoring in real-time, allowing users to track their glucose levels 24/7.
- Alerts and Predictive Features: Many insulin pumps that integrate with a CGM offer advanced features like predictive alerts for high or low glucose levels, helping users take proactive steps before glucose levels become dangerous.
Ideal for: Insulin pumps that integrate with CGM's are best suited for individuals who need precise insulin dosing and want a more comprehensive system that can manage both glucose monitoring and insulin delivery. These systems are ideal for those who need automated insulin management and real-time alerts for high or low blood sugar.

Pros and Cons of Freestyle Libre
Freestyle Libre Pros:
- Affordable: One of the most cost-effective CGM systems available.
- Easy to Use: No calibration required, and the sensor is simple to apply.
- Long Sensor Wear: The sensors last up to 14 days, reducing the frequency of replacements.
Freestyle Libre Cons:
- No Insulin Integration: Does not provide automatic insulin delivery, which means users need to manage insulin separately.
- Limited Alerts: Earlier versions lacked advanced alerts. While recent models have improved, they still don’t offer the predictive alerts found in insulin pump systems.
Pros and Cons of Insulin Pump + CGM
Insulin Pump + CGM Pros:
- Comprehensive Diabetes Management: Combines both insulin delivery and glucose monitoring, providing a more complete solution.
- Predictive Alerts: Real-time alerts and the ability to adjust insulin delivery based on glucose readings can help prevent high or low blood sugar.
- Seamless Integration: Works in tandem with your insulin delivery, offering automated insulin adjustments and reducing the need for manual injections.
Insulin Pump + CGM Cons:
- Expensive: These systems are significantly more expensive due to both the pump and CGM costs, along with ongoing maintenance.
- Complex Operation: More complex to operate, requiring regular maintenance, sensor changes, and calibration.
- Higher Maintenance: Pumps require more frequent refills, battery changes, and management of insulin levels.
Which One is Right for You?
Freestyle Libre:
The Freestyle Libre is an excellent choice for users who prioritise simplicity, affordability, and minimal equipment. If you're looking for an easy-to-use, non-invasive solution for continuous glucose monitoring without the need for insulin integration, Freestyle Libre is the way to go. It’s also a great option for people who want to track glucose trends without the complexity of an insulin pump.
Insulin Pumps with an integrated CGM:
If you require precise insulin dosing and need a more comprehensive diabetes management system, an insulin pump with a CGM is ideal. These systems are especially useful for individuals who want real-time alerts, automated insulin delivery, and advanced features like predictive high/low glucose alerts. While they come with a higher cost, they offer a more automated and integrated approach to managing diabetes.
At Type Strong, we understand how important it is to have reliable tools to manage your diabetes. Our range of adhesive patches is designed to keep your CGM sensor in place, so you can enjoy a more active lifestyle with confidence.

Frequently Asked Questions
1. How long do Freestyle Libre sensors last?
Freestyle Libre sensors last up to 14 days, after which they need to be replaced.
2. Do insulin pumps that integrate with a CGM require calibration?
Yes, insulin pumps typically require calibration with blood glucose readings, especially for optimal accuracy.
3. Can I use Freestyle Libre with an insulin pump?
No, Freestyle Libre is a CGM system that does not integrate directly with insulin pumps, so users will need to manually adjust their insulin levels.
4. What’s the best CGM for someone new to diabetes management?
For someone new to diabetes management, the Freestyle Libre may be an ideal choice due to its ease of use, simplicity, and affordability. It’s a great option for those who want to get started with CGM without the complexity of insulin pumps.
When choosing between Freestyle Libre and insulin pumps with integrated CGM, it’s important to consider your lifestyle and diabetes management needs. The Freestyle Libre offers simplicity and affordability, while insulin pumps with integrated CGM provide a more comprehensive, automated approach to diabetes management. At Type Strong, we offer products that support both systems, helping you get the most out of your diabetes tools.
