SIBIONICS GS3 is a Continuous Glucose Monitoring (CGM) system that continuously tracks glucose levels throughout the day and night. A small wearable sensor works with the GS3 app to provide continuous glucose readings and trend insights updated every 5 minutes.

The SIBIONICS GS3 CGM System is intended for individuals aged 3 years and older who want continuous insight into glucose changes, including people with Type 1 diabetes, Type 2 diabetes, as well as those seeking proactive glucose monitoring for better health management.

It is designed to support users in observing glucose trends and understanding how daily factors such as meals, activity, and sleep may influence glucose levels.

Most users experience little to no discomfort during application or wear. The GS3 system uses an automatic applicator and a flexible sensor filament designed for comfortable daily wear.

During application, the guide needle quickly inserts the flexible filament and is immediately removed — the part that remains under the skin is a soft, flexible sensor rather than a steel needle. Some users may feel brief mild discomfort during application, which typically resolves quickly. Individual experiences may vary.

Each SIBIONICS GS3 sensor is designed for up to 14 days of continuous wear. During this period, glucose data is automatically updated in the app every 5 minutes.
