C-Carbs: A CGM-guided Approach to Teaching Carb Awareness
A Novel Approach to Teaching Carb Awareness to Vulnerable Patients With Type 1 Diabetes
Source: ClinicalTrials.gov · Last updated 4 Nov 2026
Brief summary (registry, in English)
The goal of this randomized study is to learn whether a CGM-guided insulin dosing education program can help adults with diabetes improve how they dose mealtime insulin. The main question it aims to answer is: 1\. Does CGM-guided insulin dosing education improve insulin dosing behaviors and glycemic outcomes in adults with diabetes who do not routinely use carbohydrate counting? Participants will be randomly assigned to either the C-CARBS intervention or usual care. Participants will complete study visits, questionnaires, and meal and insulin logs, and CGM data will be collected to evaluate changes in insulin dosing behaviors and glycemic outcomes.
