The adrenal gland is an endocrine organ that is divided into two parts: the cortex and the medulla. The adrenal cortex secretes three types of hormones, including glucocorticoids, salt corticoids, and sex hormones. Glucocorticoid is a kind of adrenocortical hormone, which is an essential hormone to maintain normal metabolism in the body. Glucocorticoids can maintain blood sugar and blood pressure in a state of stress in the body, but in pathological states, such as adrenocortical hyperplasia, there will be too much glucocorticoids, which can manifest with buffalo back, full moon face, high blood sugar and high blood pressure, etc. It is necessary to determine whether surgical treatment or medication is needed according to the specific conditions of the disease, so patients must go to the hospital and firstly make a correct diagnosis in order to have appropriate treatment plan.
