OR:

Adrenal gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. Adrenal disorders may cause hyperfunction or hypofunction, and may be congenital or acquired. The adrenal gland produces hormones that affects growth, development and stress, and also helps to regulate kidney function. There are two parts of the adrenal glands, the adrenal cortex and the adrenal medulla. The
adrenal cortex The adrenal cortex is the outer region and also the largest part of an adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones. It is ...

Tumors of the adrenal gland

, a benign tumor of the adrenal gland which may result in overproduction of one or more adrenal hormones, or may be inactive * Adrenocortical carcinoma, cancer of the adrenal cortex * Adrenal incidentaloma, an adrenal tumor (of any type) discovered accidentally during a scan which performed for an unrelated reason * Pheochromocytoma, a catecholamine-producing tumor of the adrenal medulla, which may or may not be cancerous


Hereditary disorders associated with adrenal tumors

* Von Hippel–Lindau disease, a mutation of the VHL1 tumor-suppression gene associated with many types of tumor, including pheochromocytoma * Multiple Endocrine Neoplasia, a family of syndromes in which genetic abnormalities contribute to the development of endocrine tumors

Disorders of hormone over/under-production

* Addison's disease, also known as primary adrenal insufficiency, a disease in which the adrenal glands do not produce sufficient glucocorticoids (sometimes also mineralocorticoids) for a reason directly related to the adrenal gland itself, such as auto-immune damage to the adrenal gland or adrenal gland atrophy due to medication use *

, a condition in which the adrenal glands do not produce sufficient glucocorticoids (or sometimes mineralocorticoids. This is often due to another adrenal disorder, such as Addison's Disease or Congenital Adrenal Hyperplasia, however it may also result from a problem elsewhere in the body (such as the hypothalamus or pituitary gland) that leads to abnormalities in the production of hormones regulating adrenal function * Congenital Adrenal Hyperplasia, a hereditary disorder in which one of the enzymes involved in
