The adrenal glands are orange-colored endocrine glands which are located on the top of both kidneys. The adrenal glands are triangular shaped and measure about one-half inch in height and 3 inches in length. Each gland consists of a medulla (the center of the gland) which is surrounded by the cortex. The medulla is responsible for producing epinephrine and norepinephrine (adrenaline). The adrenal cortex produces other hormones necessary for fluid and electrolyte (salt) balance in the body such as cortisone and aldosterone. The adrenal cortex also makes sex hormones but this only becomes important if overproduction is present.
The indications for surgical removal of the adrenal gland are relatively straightforward and include, but are not limited to the following:
Note: the above conditions which indicate the surgical removal of an adrenal gland all exclude the situation in which cancer has spread from another organ to the adrenal (metastatic spread)...with very few exceptions.
The remainder of the adrenal section of this large endocrine disorders site is arranged in small segments to make topics easier to understand.
Specific hormones are discussed on pages which illustrate the typical treatment of that disorder. Illustrations and actual patient x-rays are used extensively. If you get lost, or want to see what else is discussed, go to our Home Page.
