What this study is testing
- What it's testing
- The study wants to see whether using a continuous glucose monitor (CGM) to guide insulin dosing improves how adults with type 1 diabetes manage their insulin and blood sugar, especially those who don’t normally count carbs.
- Who it's for
- Adults with type 1 diabetes who do not routinely count carbohydrates.
- What's involved
- Participants will attend study visits, fill out questionnaires, keep meal and insulin logs, and wear a CGM to track blood sugar while they try the new education program or receive usual care.
- Time commitment
- The study lasts several months, with multiple visits and ongoing CGM use to collect data.
