The adrenal glands
The adrenal glands are 2 small glands that are located on top of each kidney. The main role of the adrenal glands is to make hormones including adrenaline or steroids. Normally, only one or part of one adrenal gland can produce enough hormones for the body. Surgical removal of an adrenal gland, or adrenalectomy, is most commonly performed for a tumor located within the adrenal gland that is either producing too many hormones or is potentially cancerous. Frequently, the hormones produced by an adrenal tumor can cause high blood pressure, headaches, tremors, and other symptoms. Generally, patients are referred for an adrenalectomy after an abdominal CT scan reveals an enlarged adrenal gland.
