What does adrenal gland diseases mean?
The adrenal glands, located on the top of each kidney, are responsible for releasing different hormones. Adrenal gland disorders occur when the adrenal glands produce too much or too little of these hormones. Women may also have increased growth of hair on their face and body and experience menstrual irregularities.
What does Addison's disease do to the adrenal gland?
In Addison's Disease, the immune system mistakenly attacks the cells in the adrenal glands that make hormones. When this happens, the immune cells destroy the glands , making it harder and harder for the body to get the hormones it needs. Addison's has different names depending on if it is diagnosed in childhood or in adulthood.

What causes Addison's disease?
The most common cause of Addison's disease is an autoimmune response, which occurs when your immune system attacks healthy tissues for an unknown reason. With Addison's disease, your immune system attacks the outer portion of your adrenal glands (the adrenal cortex), where they make cortisol and aldosterone.

This disorder occurs when the body produces too much aldosterone , a hormone that controls blood pressure and regulates the body's salt and potassium levels.

What is a pheochromocytoma?
Pheochromocytoma is a type of tumor that develops in the adrenal medulla, the inner part of the adrenal gland. It produces adrenaline, causing high levels of this hormone in the body.

The pituitary gland is located at the base of the brain. It releases hormones that affect many of the body's functions. Among those hormones is the adrenocorticotropic (pronounced a-DREE-noh kawr-tuh-koh-TRO-pic) hormone (ACTH), which stimulates the adrenal glands to release the hormone cortisol.
Can a tumor on the pituitary gland cause cortisol?
Sometimes, benign (noncancerous) pituitary tumors or—more rarely cancerous tumors 1 —may grow on the pituitary gland, which can cause a variety of problems.

When adrenal glands don’t produce enough hormones, this can lead to adrenal insufficiency (Addison’s disease). Adrenal glands may develop nodules that can be benign or malignant, which can potentially produce excessive amounts of certain hormones leading to various health issues.
What is the role of adrenal glands in the body?
The role of the adrenal glands in your body is to release certain hormones directly into the bloodstream. Many of these hormones have to do with how the body responds to stress, and some are vital to existence. Both parts of the adrenal glands — the adrenal cortex and the adrenal medulla — perform distinct and separate functions.
How do adrenal glands produce cortisol?
How Adrenal Glands Work to Produce Cortisol. Adrenal glands produce hormones in response to signals from the pituitary gland in the brain, which reacts to signaling from the hypothalamus, also located in the brain. This is referred to as the hypothalamic pituitary adrenal axis. As an example, for the adrenal gland to produce cortisol, ...
What are the two parts of the adrenal gland?
An adrenal gland is made of two main parts: 1 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. 2 The adrenal medulla is located inside the adrenal cortex in the center of an adrenal gland. It produces “stress hormones,” including adrenaline.
Where does excess cortisol come from?
Excess cortisol production can occur from nodules in the adrenal gland or excess production of ACTH from a tumor in the pituitary gland or other source.
Which part of the adrenal gland secretes hormones?
Both parts of the adrenal glands — the adrenal cortex and the adrenal medulla — perform distinct and separate functions. Each zone of the adrenal cortex secretes a specific hormone. The key hormones produced by the adrenal cortex include:
