DIABETES TEATED IN GENERAL PRACTICE. Blood glucose monitoring has been an integral part of diabetes treatment for many years, whether for type 1 diabetic patients on multiple daily injections of insulin, insulin pumps or artificial pancreas, and now for patients with type 2 diabetes, even without intnsified insulin therapy. Capillary blood glucose testing with glucose meters, developed in the 80s, has been largely replaced by continuous glucose monitoring with subcutaneous sensors, which since the early 2000s have revolutionized diabetes management, understanding and day-to-day monitoring, for patients and healthcare profressionals alike. Thanks to this continuous monitoring of circulating glucose levels, new performance indices have emerged and are now the subject of international consensus. Therapeutic objectives have been refined, with a shift from discontinuous, cross-sectional measurement of capillary glucose to continuous monitoring of interstitial glucose, enabling control, while also taking a safe look at time spent in areas of hypoglycemic risk and/or high hyperglycemia. The performance of these glucose sensors has been well established in terms of improving glycemic control and preventing certain complications associated with diabetes, justifying an extension of their reimbursement. These modern diabetes monitoring tools open up an impressive range of opportunities for personalized treatment, ultimately reducing the risk of hyperglycemia-related complications and improving patient comfort.
