Evaluation of the Glucose Metrics After Eating Pizza Margherita in Hybrid Closed Loop Users

In previous study the investigators proved that blood glucose after eating pizza margherita could be managed with a simple wave bolus of insulin in pediatric patients with type 1 diabetes under controlled conditions. Participants in this previous study were Predictive Low Glucose Suspended (PLGS) System users. In this study the investigators want to demonstrate that blood glucose after the meal pizza margherita could also be managed with simple wave bolus of insulin in real life. The investigators will include just the patients with Hybrid Closed Loop (HCL) System.

Inclusion Criteria:The patients aged between 8- 18 will be included in the study just in a condition of using HCL Systems at least 3 monthsExclusion Criteria:Patients with HbA1c >8.5 % (69 mmol/mol), celiac disease, other food allergies will be excluded.
