The Effect of Basal Insulin During Exercise on the Development of Hypoglycemia in Children With Type 1 Diabetes
In Brief
An observational study for Diabetes Mellitus, Type I. Completed, across 6 sites.
Detailed Summary
Most children with type 1 diabetes have a drop in the blood sugar during exercise. This drop in the blood sugar can result in hypoglycemia (low blood sugar). In children using an insulin pump, there is an opportunity to reduce the basal insulin rate during exercise. This study is being conducted to determine if decreasing the insulin that is received during exercise will reduce the risk of hypoglycemia. We hope to learn more about how the body responds to hypoglycemia and to hyperglycemia (high blood sugar) when it occurs. As part of the study, children will have a visit on two different days. During each visit, children will exercise on a treadmill for about 60 minutes. During one of the visits, the children's basal rate will be continued during the exercise. During one visit, the basal insulin will be stopped. The blood sugar will be checked frequently during the exercise.
