Adrenal Disorders

The adrenal glands are located just above kidneys on both sides. There are two parts of the adrenal glands, the adrenal cortex and the adrenal medulla. The adrenal cortex produces cortisol (steroid hormone that regulates every organ and tissue within the body including immune system) and aldosterone, which helps to maintain salt levels (sodium and potassium) and fluid within the body.

Adrenal medulla produces hormones called adrenaline (epinephrine), that helps to control blood pressure, heart rate, and sweating. Adrenal disorders can cause your adrenal glands to produce too much or insufficient hormones.

With Cushing''s syndrome, there is too much cortisol, while with Addison's disease, there is too little. Some people are born unable to make enough cortisol.
