Diabetes Management Devices: CGMs & Insulin Pumps
Diabetes technology has come a long way, providing advanced tools that help people manage their blood sugar levels more effectively and with greater ease. If you’re new to Continuous Glucose Monitors (CGMs) or insulin pumps, this guide will introduce you to these life-changing devices, explaining what they do, how they work, and how they can improve your diabetes management
Continuous Glucose Monitors (CGMs)
What is a Continuous Glucose Monitor (CGM)?
A CGM is a small wearable device that tracks blood sugar levels continuously throughout the day and night. Unlike traditional fingerstick tests that provide a single blood sugar reading, CGMs show real-time trends and patterns, allowing you to take action before levels become too high or too low.
CGMs use a tiny sensor inserted under the skin to measure glucose levels in the interstitial fluid. The data is sent to a receiver or smartphone, giving users an up-to-date picture of their blood sugar without the need for frequent fingersticks. Some CGMs also feature alarms that alert users when their glucose levels are dangerously high or low, helping prevent emergencies.
Dexcom CGMs
Dexcom CGMs provide continuous glucose monitoring with real-time updates and integration with insulin pumps. These devices are widely used and trusted for their accuracy, ease of use, and seamless data sharing with healthcare providers and loved ones.

- Works with a smartphone app for quick and easy glucose checks without scanning.
Insulin Pumps
What is an Insulin Pump?
An insulin pump is a small, wearable device that delivers insulin automatically to help keep blood sugar levels stable. Unlike injections, insulin pumps can deliver small, steady amounts of insulin throughout the day and allow for larger doses at mealtimes, making diabetes management more convenient.
Insulin pumps typically include a small infusion set that attaches to the skin and delivers insulin through a thin tube. Some advanced pumps work alongside CGMs to adjust insulin delivery automatically based on glucose readings, reducing the need for constant manual adjustments.
Tandem Insulin Pumps
Tandem’s t:slim X2 insulin pump is designed for users who want advanced insulin control with automated adjustments. This pump features Control-IQ technology, which works with CGMs to adjust insulin delivery automatically, helping to maintain stable blood sugar levels with less effort.
Tandem t:slim X2
- Hybrid closed-loop system that adjusts insulin delivery based on CGM data.
- Works with Dexcom G6 and G7, allowing for seamless integration.
- Rechargeable battery via micro-USB, reducing the need for disposable batteries.
- Allows user-controlled bolus dosing for precise insulin management.
- Touchscreen interface makes navigation simple and intuitive.
- Customizable insulin delivery settings to fit individual needs.
Beta Bionics Insulin Pumps
The Beta Bionics iLet takes a completely automated approach to insulin delivery. Unlike traditional pumps, it does not require carb counting or manual bolus adjustments. Instead, users enter their weight, and the system learns and adapts over time.
Beta Bionics iLet
- Fully automated insulin delivery system, reducing the need for user input.
- No carb counting required—just enter your weight, and the pump does the rest.
- Works with Dexcom G6, with future integration planned for the G7.
- Simple, user-friendly interface with minimal settings, making it easy for beginners.
- Future-ready for dual-hormone therapy (insulin + glucagon pending FDA approval).
- Plug-and-play simplicity, ideal for those who want a hands-off approach to diabetes management.
Which Device is Right for You?
Choosing the right diabetes technology depends on your lifestyle, medical needs, and personal preferences.
- Consider a Dexcom CGM if you want real-time data integration with insulin pumps and smart devices.
- Consider a FreeStyle Libre CGM if you want longer wear time and less frequent sensor replacements.
- Consider the Tandem t:slim X2 if you want customizable insulin delivery with a hybrid closed-loop system.
- Consider the Beta Bionics iLet if you prefer a fully automated insulin system with no carb counting.
For personalized recommendations, consult with your healthcare provider to determine the best device for your lifestyle and diabetes management needs.
