Brief summary
The purpose of this study is to determine what corticosteroid receptor (and the dose of) is responsible for cortisol inducing hypoglycemia associated autonomic dysfunction in Type 1 DM. Specifically, we aim to determine whether stimulating the type 1 corticosteroid receptor (via fludrocortisone), the type 2 corticosteroid receptor (via dexamethasone), or both causes hypoglycemia associated autonomic dysfunction in Type 1 DM.
Interventions
Oral Fludrocortisone 0.2 mg x 2 prior to each experimental period on Day 1
Oral Dexamethasone 0.75 mg x 2 administered prior to each experimental period on Day 1
