This allows persons with diabetes to prevent hypoglycemic and hyperglycemic events. Scientific evidence indicates that the system can improve glycemic control and quality of life. To obtain the maximum benefit, it is necessary to properly handle glucose values and trends. Due to the generalization of the system use, the purpose of the document is to provide recommendations for the optimal use of the device, not only in the management of glucose values and trends but also in the prevention of hypoglycemia, actuation in exercise, special situations, and retrospective analysis of the glucose data, among others.enambulatory glucose profileflash glucose monitoringinterstitial glucosetype 1 diabetestype 2 diabetesBlood GlucoseBlood Glucose Self-MonitoringDiabetes Mellitus, Type 1HumansHypoglycemiaHypoglycemic AgentsInsulinQuality of LifeRetrospective Studiesresearch article31081362open access10.1177/19322968198419111932-2968PMC7189166https://journals.sagepub.com/doi/pdf/10.1177/1932296819841911https://pmc.ncbi.nlm.nih.gov/articles/PMC7189166/pdf
