Through the interpretation of glucose profiles and graphs obtained by continuous glucose monitoring (CGM), clinicians and patients can mutually communicate and analyze the short-term glycemic profiles of patients. The interpretation of retrospective CGM graphs should be conducted in three steps: first, analysis of nocturnal blood glucose; second, analysis of preprandial blood glucose; and third, analysis of postprandial blood glucose. In each step, hypoglycemia is observed first, followed by hyperglycemia, and then the results are analyzed to find specific causes that impact glucose in order to guide decisions on treatment. The real-time CGM system is of great value in the prevention and treatment of hypoglycemia and in the achievement of stable glycemic control. By presenting practical cases, this chapter introduces the methods for interpreting both retrospective and real-time CGM data on the basis of theory as well as clinical practice.
