Cardiometabolic Benefit of Reducing Iatrogenic Hyperinsulinemia Using Insulin Adjunctive Therapy in Type 1 Diabetes

Description

This study aims to understand the heart and blood sugar health benefits of using an adjunctive therapy to lower high insulin levels in people with type 1 diabetes. The investigators will also look at people with a specific type of diabetes called Glucokinase-Maturity Onset Diabetes of the Young (GCK-MODY) and those without diabetes to help interpret the results. The investigators will use a medication that helps the body get rid of sugar, called and SGLT2 inhibitor, with the goal to reduce the body's insulin requirements. The investigators believe this could lead to better heart and blood sugar health, including a better response to insulin and more available nitric oxide, a gas that helps blood vessels function well. The investigators will compare heart and blood sugar health risk factors in participants with type 1 diabetes, participants with Glucokinase-Maturity Onset Diabetes of the Young (GCK-MODY), and non-diabetic healthy volunteers under two conditions: high insulin levels typical of type 1 diabetes and normal insulin levels typical of the other two groups.
