Hypothalamic-pituitary-adrenal(HPA)axis-related factors in patients with type 2 diabetes were studied according to different levels of HbA1C.It showed that HPA axis was normal in HbA1C≤ 7% group[ACTH (18.03±8.39)ng/L,blood cortisol(49.22±8.68)μg/L],hyperactive in 7%11% group with weak feedback regulation[ACTH(26.08±15.41)ng/L,blood cortisol(55.64±24.27)μg/L].These results suggest that HPA axis-related factors in type 2 diabetic patients are different with different grades of glucose metabolic turbulence.
