The Different Response of Endocrine Hormones to Hypoglycemia in Patients With Type 1 or Type 2 Diabetes

May 29, 2023 updated by: Jian-hua Ma, Nanjing First Hospital, Nanjing Medical University

A Study of Endocrine Hormone Changes in Newly Diagnosed Patients With Type 2 and Type 1 Diabetes Using Hyperinsulinaemic Hypoglycaemic Clamp Technique

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.
