Small Steps to Big Impact: FreeStyle Libre CGM Systems for Diabetes Management

FreeStyle Libre continuous glucose monitoring (CGM) systems help individuals with diabetes track glucose levels without finger pricks, showing patterns and impacts of food, sleep, and exercise on glucose levels. The system provides accurate readings every minute and can help lower A1c levels. It is the #1 sensor worldwide and a painless way to monitor glucose levels.

Abbott's FreeStyle Libre continuous glucose monitoring (CGM) systems have become a cornerstone in diabetes management, offering a non-invasive way to track glucose levels without the need for finger pricks. This technology, which provides accurate readings every minute, has shown significant potential in helping individuals with diabetes better understand the impact of food, sleep, and exercise on their glucose levels, ultimately aiding in the reduction of A1C levels. As of 2025, the FreeStyle Libre is the leading CGM sensor globally, setting a new standard for painless glucose monitoring.

Abbott's latest quarterly results reflect the company's robust performance in the second quarter of 2025, with a 7.4% increase in sales, driven by a 7.5% organic growth rate excluding COVID-19 test sales. The company's adjusted EPS rose to $1.26, marking a double-digit annual growth. Looking ahead, Abbott projects full-year 2025 organic sales growth of 7.5%-8.0% excluding COVID-19 testing sales, with adjusted diluted EPS expected to fall between $5.10 and $5.20 [2].

The Medical Devices segment, particularly the Diabetes Care unit, has been a standout performer. Sales of the FreeStyle Libre CGM system reached $1.9 billion in the second quarter of 2025, marking a 21.4% increase. This growth is attributable to the system's ability to provide real-time glucose data, which helps patients make informed decisions about their diet and lifestyle, thereby improving their overall health outcomes [2].

Continuous glucose monitoring systems like the FreeStyle Libre have evolved significantly over the years, with advancements in electrode design, enzyme modification techniques, and outer membrane technologies. These improvements have led to better performance in critical indicators such as anti-interference capability, response time, stability, sensitivity, and linear range [1]. The ability to monitor glucose levels continuously and provide real-time data has made these systems invaluable for diabetes management.

In addition to its clinical applications, the FreeStyle Libre has gained popularity among health enthusiasts and athletes who use it to track their body chemistry and nutrition. Olympic marathoner Abdi Nageeye used a CGM to monitor his energy levels ahead of the Paris Olympics, highlighting the broader appeal of these devices [4]. The Abbott Lingo, an over-the-counter (OTC) CGM, was approved in 2024 and is designed for people aged 18 and up interested in tracking their blood sugar without a diabetes diagnosis [4].

The FreeStyle Libre's success underscores Abbott's commitment to innovation and patient care. By providing a painless and accurate way to monitor glucose levels, the system has become an essential tool for managing diabetes. As the company continues to invest in research and development, it is poised to maintain its leadership in the CGM market, driving further advancements in diabetes management and beyond.
