20 Years of Continuous Glucose Monitoring in India: Options and Indications

Abstract

The increasing prevalence of diabetes worldwide is a major concern, especially in developing countries where achieving optimal glycemic control is challenging. Continuous Glucose Monitoring (CGM) systems have revolutionized diabetes management by providing detailed and real-time insights into glucose fluctuations. Over the past 20 years, CGM technology has significantly evolved with improved accuracy, user-friendliness, and clinical utility. This review discusses the progressive development of CGM systems in India, types of CGM systems including professional, real-time, intermittently scanned, and integrated CGMs, and their specific indications. The review also highlights novel innovations in CGM and explores the importance of metrics such as Time in Range (TIR) and Time in Tight Range (TITR) in glycemic management. By enhancing patient and healthcare provider decision-making, CGM systems have become an inevitable part of diabetes care, offering a more comprehensive and effective approach to managing the condition.
