BACKGROUND Continuous glucose monitors (CGM) play an important role in type 2 diabetes management, offering benefits such as improved glucose awareness, behavioural adjustments, and reduced anxiety. While generally accepted by persons with T2D, challenges such as pain from sensor insertion and skin reactions to the adhesive may hinder their effectiveness. This qualitative study aims to examine how individuals with T2D perceive the clinical and personal benefits of CGM, as well as the challenges affecting its long-term use. By understanding patient experiences, this project seeks to inform clinical education, enhance patient support strategies, and promote CGM adoption and adherence. OBJECTIVE This qualitative study aims to explore T2D person’s perceived benefits and challenges associated with using CGM METHODS This study used an online questionnaire survey to explore the experiences of CGM of individuals with T2D in the UK. A total of 531 participants were recruited in October 2024. Thematic analysis identified key benefits and challenges associated with continuous glucose monitoring (CGM) use. RESULTS Participants identified several key benefits, which were categorised into five overarching themes, including (i) practicality, (ii) better understanding of lifestyle impacts on glucose levels, (iii) improved self-management, (iv) improved safety, and (v) enhanced data sharing with healthcare providers. The main challenges identified included (i) limited access, (ii) usability and technological issues, (iii) overreliance on passive monitoring, (iv) emotional burden, and (v) data-related issues. CONCLUSIONS Participants provided valuable insights into the experiences of individuals with T2D using CGM, particularly regarding its perceived benefits and challenges. Despite the benefits demonstrating that CGM is a valuable tool for T2D management, these findings emphasise the need for improved accessibility, user-friendly technology, and tailored education to enhance CGM adoption and long-term adherence.
