## Abstract

The management of diabetes mellitus is fundamentally reliant on the accurate measurement of glycemic levels. For decades, self-monitoring of blood glucose (SMBG) via finger-stick blood glucose meters (BGMs) has been the cornerstone of daily diabetes care. However, the advent of continuous glucose monitoring (CGM) systems represents a paradigm shift, offering real-time interstitial fluid glucose readings, trend data, and hypoglycemic alerts. This review delineates the fundamental principles, developmental history, and comparative advantages and disadvantages of BGM and CGM technologies. We explore the technical evolution from first-generation reflectance meters to modern, connected BGMs and from retrospective professional CGMs to minimally invasive, real-time personal and factory-calibrated systems. Furthermore, we project the future trajectory of these technologies, including non-invasive methods and algorithmic integration. A specific focus is placed on the Middle East and North Africa (MENA) region, which bears one of the world's highest diabetes prevalence rates. We analyze the current market dynamics and project a significant growth in CGM adoption from 2025 to 2035, driven by increasing awareness, competitive pricing, and crucial expansions in healthcare reimbursement, even as BGM remains a vital tool for large segments of the population.
