Introduction to SMBG

Abstract Self-monitoring of blood glucose (SMBG), over its half a century of clinical use, gradually developed into an evidence-based standard of care in the management of insulin therapy in both type 1 and type 2 diabetes. The chapter discusses the historical aspects of SMBG development and gradual accumulation of clinical evidence for its efficacy in improving metabolic control and reducing hypoglycemia in insulin-treated diabetes, culminating in landmark clinical trials demonstrating that intensive insulin therapy informed by SMBG delays and/or prevents chronic complications of diabetes. Additionally, data on the use of SMBG in noninsulin-treated diabetes are presented. Finally, current clinical guidelines for different populations of people with diabetes are discussed.
