CGM vs. insulin pump: which is more effective, MiniMed 780G or SIBIONICS GS1?

Diabetes management has reached a new level — technology now helps monitor glucose levels in real time and can even automatically adjust insulin delivery. The medical equipment market offers two main approaches: continuous glucose monitoring (CGM) systems and «smart» insulin pumps. This article aims to explain the differences between two popular solutions — the MiniMed 780G and the SIBIONICS GS1 — and clarify when monitoring alone is sufficient and when it is better to choose a fully automated system.

What is the difference between CGM and an insulin pump?

What is a sensor for diabetics? A CGM (Continuous Glucose Monitoring) system is a device designed for continuous monitoring of glucose levels. It measures blood sugar in real time and transmits the data to a smartphone, receiver, or other compatible device. A CGM does not deliver insulin; it only monitors the body’s condition to allow timely response.

What is an insulin pump? It is a device that delivers insulin into the body through a catheter. Modern devices, such as the MiniMed 780G, are capable of operating in automatic mode. The device analyzes data from the connected CGM (Guardian Sensor 4) and adjusts the insulin delivery. The combination of a compatible CGM and pump has several advantages:

• no need for manual calculations and injections;

• more stable glucose levels throughout the day;

• reduced risk of hypo- or hyperglycemia;

• more freedom in diet and activity.

The sensor continuously transmits readings to the pump, which analyzes the data and adjusts insulin delivery. The paired devices work together as a complete automated system.

Device overview

Modern technologies in diabetes treatment allow not only to control blood sugar levels, but also to automatically adjust insulin delivery. Leading manufacturers offer innovative solutions for both simple monitoring and full automation. To choose the best device, you should analyze the popular SIBIONICS GS1 and MiniMed 780G, which provide an effective approach to monitoring and automatic correction of blood glucose.

SIBIONICS GS1

SIBIONICS GS1 is a new generation continuous glucose monitoring system. The device is designed for people with diabetes, as well as those who need regular monitoring of their blood sugar levels. The advanced sensor included in the kit consists of a thin, flexible thread that is inserted under the skin and an external transmitter that is attached to the skin. Key features of the CGM system:

• 14 days of operation;

• no calibration required;

• Bluetooth transmission to devices;

• convenient mobile app with graphs and alerts;

• waterproof housing.

SIBIONICS GS1 is comfortable to use and has a long service life. Thanks to this system, constant finger pricks are no longer necessary. The device does not control insulin delivery, but only monitors it.

MiniMed 780G

The MiniMed 780G is a high-tech, multifunctional insulin pump with automatic insulin delivery and calculation based on CGM data. It is suitable for patients who want to automate their diabetes management as much as possible. How the insulin pump works:

• Guardian Sensor 4 sensor;

• algorithm: SmartGuard — analysis and dose correction every 5 minutes;

• automatic boluses;

• protection against hyperglycemia and hypoglycemia;

• target sugar level setting;

• color screen, control from the pump or via the app.

The device minimizes manual intervention and promotes stable readings. The pump is more expensive than CGM and requires regular replacement of infusion sets.

Comparison table for SIBIONICS GS1 and MiniMed 780G

Here is the table below with the main features of SIBIONICS GS1 and MiniMed 780G to compare the capabilities of two popular devices for diabetes management. It helps you understand what features each system offers and who it is suitable for.

Feature	SIBIONICS GS1	MiniMed 780G
Device type	CGM	Insulin pump that integrates with CGM
Insulin delivery control	No	Automatic
Sensor life	14 days	7 days (Guardian Sensor 4)
Calibration required	No	No
Data access	Smartphone	Pump screen + app
Suitable for	Blood sugar monitoring	Fully automatic mode

Based on the table, the SIBIONICS GS1 is suitable for blood sugar monitoring and trend analysis. MiniMed 780G provides full automatic control with insulin delivery. The choice between the two devices depends on whether you only need monitoring or require maximum automation of your diabetes therapy.

When is it enough to use CGM alone?

Blood glucose monitoring systems CGM may be sufficient for diabetes control when there is no need for insulin delivery. The devices allow you to track your blood sugar levels in real time, see trends, and respond to changes in a timely manner. The device is relevant in the following cases:

1. Type 2 diabetes, treated with tablets or basal insulin.

2. Effective glucose control through diet and exercise.

3. Stable readings without sudden spikes.

4. Desire to reduce the number of finger pricks and simplify monitoring.

5. Trend analysis for lifestyle and treatment adjustments.

In these cases, CGM acts as a «monitoring tool» for the patient, showing the real situation. The decision to administer insulin or adjust treatment is made by a specialist and the user.

A glucose monitoring system without a pump is suitable for people who already know how to select their own insulin doses, use pen injectors or traditional injections, and want to improve their blood sugar control without changing their usual method of administration. With CGM, users can detect hidden fluctuations in glucose levels, for example at night or after physical activity.

When is an insulin pump with automatic insulin delivery needed?

An insulin pump with automatic mode is especially useful for patients with type 1 diabetes or those who use multiple injections per day. It takes over part of the control, automatically administers insulin, and adjusts the delivery through integration with CGM. The device should be used in the following situations:

1. Frequent fluctuations in blood sugar levels, hypo- and hyperglycemia.

2. Use of intensive insulin therapy with daily injections.

3. Need for automation of dose calculations and injection quantities.

4. Desire to improve quality of life and maximize control of the disease.

5. Protection against sudden spikes in glucose at night or during activity.

The insulin pump works based on a «smart system» that regulates the insulin dose. This reduces the risk of complications and makes it easier to manage diabetes on a daily basis.

The combined system is suitable for patients who find it difficult to achieve a stable glycemic profile. An insulin pump in combination with CGM is convenient for children and adolescents, where automation and minimization of manual calculations are important. The devices are effective for people with busy schedules who do not have time for constant monitoring.

Conclusion

SIBIONICS GS1 is a reliable and convenient blood sugar measurement system that eliminates the need for frequent finger pricks and provides real-time sugar data. It is suitable for those who need to monitor their levels rather than automatic insulin delivery. MiniMed 780G is a comprehensive automated system that adjusts insulin doses every 5 minutes and requires a sensor to monitor glucose levels. This approach helps stabilize levels and reduce the risk of complications, especially in type 1 diabetes.

When choosing the right solution, it is important to consider your treatment goals, lifestyle, and specialist recommendations.
