Nanjing First Hospital, Nanjing Medical University35 enrolled

Overview

Endocrine hormones, not only blood glucose responsive hormones, but also sexual hormones, thyroid hormones, growth hormones and so on, may have response and activites in hypoglycemia. However, the different responses of endocrine hormones to hypoglycemia in patients With diabetes remain unclear.

This study will observe the changes of insulin, C-peptide, glucagon, growth hormone, IGF-1, ACTH, cortisol, thyroid function, sexual hormone in newly diagnosed men with type 2 and type 1 diabetes mellitus using hyperinsulinaemic hypoglycaemic clamp technique
