Welcome to the Loop Observational Study

What is the Loop Observational study?

The study is being done in collaboration with Loop developers to collect information from adults and children with type 1 diabetes using Loop. It is being paid for by the Helmsley Charitable Trust. The purpose of the study is to collect information from at least 300 – 1,250 adults and children with T1D using Loop in the United States. This information will be used to learn more about how well Loop works, what problems users have, how often severe hypoglycemia and diabetic ketoacidosis occur, and how well the system controls blood sugar levels.

Who can participate?
