Introduction

Managing insulin-dependent diabetes requires constant vigilance to maintain stable blood glucose levels. People living with type 1 diabetes—and some with type 2 diabetes—must balance insulin intake, physical activity, meals, and other factors to prevent both high and low blood sugar. Traditionally, this has involved multiple daily injections and frequent finger-prick tests, which can be time-consuming and stressful.

However, advancements in diabetes technology have revolutionised care. The integration of insulin pumps with continuous glucose monitors (CGMs) has emerged as a game-changing solution. These devices work together to provide automated insulin delivery based on real-time glucose readings, reducing the burden of diabetes management and improving overall health outcomes.

In this article, we'll explore the benefits of using insulin pumps alongside CGMs, highlight the latest devices available in the UK as of February 2025, and provide insights into important considerations for patients.

Benefits of Combining Insulin Pumps with CGMs

1. Improved Glycemic Control

One of the biggest advantages of using an insulin pump with a CGM is the ability to maintain blood glucose levels within a target range more consistently. Unlike traditional methods, which rely on periodic glucose checks, a CGM provides continuous readings, often updating every few minutes.

When paired with an insulin pump, this data enables automated insulin delivery adjustments, helping to prevent spikes and crashes. Many modern systems, such as hybrid closed-loop systems, use advanced algorithms to anticipate glucose trends and modulate insulin doses accordingly. Studies have shown that these technologies can lead to significant reductions in HbA1c levels, lowering the risk of long-term complications like neuropathy, retinopathy, and cardiovascular disease.

2. Reduction in Hypoglycaemic Events

Hypoglycaemia (low blood sugar) is a serious risk for people using insulin. Severe episodes can cause dizziness, confusion, unconsciousness, and even seizures. A major benefit of using a CGM-equipped insulin pump is the ability to predict and prevent lows before they happen.

Many systems feature predictive alerts and automatic insulin suspension when a drop in blood sugar is detected. For example, the Tandem t:slim X2 with Control-IQ technology can adjust basal insulin to prevent hypoglycaemia, giving users peace of mind—especially during sleep or physical activity when lows are harder to detect.

3. Enhanced Quality of Life

Managing diabetes can be exhausting, with frequent calculations, injections, and glucose checks. The combination of an insulin pump and CGM reduces much of this burden. Automated insulin delivery means fewer manual boluses, and the continuous glucose data eliminates the need for constant finger-pricking.

For many users, this translates to greater flexibility in daily activities, including exercise, social events, and travel. Parents of children with diabetes also find comfort in remote monitoring features, which allow them to track their child's glucose levels via smartphone apps.

4. Data-Driven Insights for Better Management

Diabetes management is highly individualised, and having access to detailed glucose data can empower patients to make informed decisions. Insulin pumps and CGMs store historical glucose readings, insulin doses, and activity levels, which can be reviewed by healthcare providers to fine-tune treatment plans.

Many devices now sync with apps that generate easy-to-read reports, highlighting trends and patterns. This data-driven approach helps users adjust their lifestyle, meal planning, and insulin settings for optimal control.

Latest Insulin Pump and CGM Devices Available in the UK (as of February 2025)

1. Medtronic MiniMed™ 780G System

This system is particularly beneficial for individuals looking for a hands-off approach to insulin management while maintaining tight glucose control.

2. Omnipod 5

The Omnipod 5 is the UK’s first tubeless automated insulin delivery system. It works with the Dexcom G6 CGM, providing seamless integration for real-time glucose monitoring and automated insulin delivery.

Key Features:

  • Wireless, tubeless design for discreet wear
  • Waterproof and suitable for active lifestyles
  • Smartphone-controlled insulin delivery

Its small, adhesive-based design makes it a popular choice for those who prefer a pump without tubing, offering greater flexibility for daily activities.

3. Tandem t:slim X2 with Control-IQ Technology

The Tandem t:slim X2 is an insulin pump that pairs with the Dexcom G6 CGM, offering Control-IQ technology for automated insulin delivery based on glucose trends.

Key Features:

  • Customisable basal insulin settings
  • Touchscreen interface for easy navigation
  • Predictive glucose adjustments to prevent highs and lows

This device is ideal for individuals who want a customisable hybrid closed-loop system with a user-friendly interface.

4. Ypsomed mylife YpsoPump with CamAPS FX

The YpsoPump is a compact, lightweight insulin pump that integrates with the FreeStyle Libre 3 sensor using CamAPS FX technology. It provides automated insulin delivery and can be controlled via a smartphone app.

Key Features:

  • Small, discreet design
  • Fully smartphone-controlled insulin adjustments
  • Compatibility with FreeStyle Libre 3 for real-time glucose readings

This system is well-suited for those who prioritise a minimalistic design and smartphone-based control.

Considerations for Patients

1. Accessibility and NHS Availability

The UK’s NHS has been rolling out hybrid closed-loop systems since April 2024, prioritising people with the greatest need. However, access can vary based on location and clinical eligibility. Patients should check with their diabetes care team to see if they qualify for NHS-funded devices.

2. Cost Implications

For those purchasing devices privately, cost can be a major factor. Expenses include:

  • Device purchase or rental fees
  • CGM sensors and infusion sets (typically replaced every 7–14 days)
  • Software subscriptions for advanced features

Private health insurance may cover some costs, but out-of-pocket expenses can add up. It’s important to research options and check for financial assistance programs.

3. Personalisation of Therapy

Not all insulin pumps and CGMs are suitable for everyone. Factors such as lifestyle, age, insulin needs, and personal preferences play a crucial role in choosing the right system. Consulting an endocrinologist or diabetes specialist is essential to determine the best fit.

Conclusion

The combination of insulin pumps and continuous glucose monitors has transformed diabetes management, offering better glycemic control, fewer hypoglycaemic events, and improved quality of life. With advancements in automated insulin delivery, patients now have more options than ever to personalize their treatment and reduce the burden of daily diabetes care.

As of February 2025, several state-of-the-art devices are available in the UK, including the Medtronic MiniMed 780G, Omnipod 5, Tandem t:slim X2, and Ypsomed mylife YpsoPump. Each system has unique features to cater to different patient needs.
