Children and adolescents with T1DM between the ages of 9-18 and undergoing insulin infusion pump therapy followed in Ege University Pediatric Endocrinology Department will be randomly selected regardless of metabolic control. The selection of the cases will be made from the beginning of the study as the first 30 patients who meet the research participation criteria and agree to participate in the study. Before the research starts, the cases will be told about the application of CGMS, their responsibilities in the research, and an appointment will be given for the insertion of CGMS and this procedure will be applied to all participants. On the day of the appointment, the participant will be put on CGMS, and as long as CGMS is attached, they will be asked to measure capillary blood glucose in their diaries and record them. The subjects will be checked whether they are within the target blood glucose values for 2 days before consuming the test meal and normoglycemia will be provided. On the first day of the study, a test meal with 80 g carbohydrate (29.3%), 70.2 g fat (57.9%), 34.7 g protein (12.7%), will be consumed in the evening meal and carbohydrate counting-normal bolus insulin will be given by administration. On the second day of the study, the additional insulin for fat and protein will be given as a dual wave bolus instead of the normal bolus for the test meal. Then, CGMS will be extracted from the cases, transferred to the computer, and analysis will be made by the researcher, taking into account the capillary blood glucose measurements in the diary.
