Cortisol is a steroid hormone or a glucocorticoid, and the use of these terms are interchangeable
For pituitary patients with secondary adrenal insufficiency, either as a direct result of the mass effects of the pituitary tumour or as a side effect of treatment (e.g. surgery, radiotherapy), steroid replacement therapy is generally lifelong and essential for life.
Cortisol is commonly known as the “stress hormone”, as the amount of cortisol in the blood raises to combat stressful events. People with adrenal insufficiency need to learn to adjust their steroid dosages in times of physical and mental stress.
