The adrenal gland is an endocrine organ, involved in the energy metabolism of cells in the body. In addition, the hormones of the gland also partially support the stabilization of blood pressure, maintain homeostasis and help the body cope with stress. When suffering from chronic adrenal insufficiency, the body cannot avoid certain complications, affecting daily activities.

Addison's disease (adrenal insufficiency) is a disorder of hormones secreted by the adrenal glands, mainly cortisol and aldosterone. The disease can lead to Addisonian crisis, leading to shock, which is life-threatening. Therefore, people with Addison's disease need to go to the hospital to check and adjust the appropriate hormone levels.

Chronic adrenal insufficiency is a condition of decreased glucocorticoid or mineralocorticoid hormones or both, caused by many factors. The disease occurs slowly over a long period of time before symptoms appear.
