Research DescriptionIn type 1 diabetes, the pancreas produces little or no insulin. Novel diabetes technologies have been developed that use a blood sugar sensor to judge when to either pause the amount of insulin that is delivered or increase the amount delivered to help keep blood sugars in the target range. Type 1 diabetes is an independent risk factor for the development of decreased sensitivity to insulin in adolescents, and women with type 1 diabetes have a decreased sensitivity to insulin when compared to men with type 1 diabetes. A decreased sensitivity to insulin is known to increase the risk for developing both heart and kidney disease. Dr. Tommerdahl hypothesizes that the pauses in insulin delivery that are unique to new diabetes technologies could increase sensitivity to insulin, particularly in women, thereby decreasing the likelihood of heart and kidney disease and improving the health of women with type 1 diabetes.
