What can go wrong with the adrenal glands?
The adrenal medulla, the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions.
What hormones does the adrenal gland secrete?
The adrenal glands have two parts: the cortex and the medulla. The cortex is the outer part of the gland. It produces the hormones cortisol and aldosterone. The medulla, meanwhile, is the inner part of the gland. It produces the hormones adrenaline and noradrenaline. These four hormones are essential to normal functioning in the body.

Can adrenal glands cause weight gain?
Benign (non-cancerous) adrenal tumors can cause hormone over-production leading to weight gain. The hormone being over-produced depends on which cell in the adrenal gland it arose from.
What doctor takes care of adrenal glands?
If you have adrenal insufficiency, your provider will refer you to an endocrinologist — a hormone specialist.
What can cause damage to the adrenal glands?
Damage to the adrenal glands in Addison's disease is usually caused by autoimmune disease—when your immune system attacks your body's own cells and organs. In developed countries, autoimmune disease causes 8 or 9 of every 10 cases of Addison's disease. Certain infections can also cause Addison's disease.
What autoimmune disease causes adrenal insufficiency?
This is called an autoimmune disorder. Addison's disease can develop if your immune system attacks your adrenal glands and severely damages your adrenal cortex. When 90% of the adrenal cortex is destroyed, your adrenal glands will not be able to produce enough of the steroid hormones cortisol and aldosterone.
What causes adrenal gland disease?
Adrenal gland disorders are caused by problems with one or both adrenal glands or by problems with other glands, such as the pituitary gland. Specific disorders can develop when the adrenal glands produce too few or too many hormones, or when too many hormones are introduced from an outside source.

What do Adrenal Glands Do?
Adrenal glands produce hormones required for healthy life. The adrenal cortex produces hormones that controls sex (androgens, estrogens), salt balance in the blood (aldosterone), and sugar balance (cortisol). The adrenal medulla produces hormones involved in the fight-or-flight response (catecholamines, or adrenaline type hormones such as epinephrine and norepinephrine).
What is the adrenal medulla stimulated by?
Stimulation of the adrenal medulla is via preganglionic sympathetic fibers causing release of dopamine, norepinephrine and epinephrine. Sympathetic neural outflow is increased by the fight-or-flight response, fear, emotional stress, upright posture, pain, cold, hypotension, hypoglycemia and other stress. Norepinephrine exerts negative feedback at the preganglionic sympathetic receptors. With increasing age, there is no change in epinephrine levels, but norepinephrine and total plasma catecholamine are increased.
What are the layers of the adrenal cortex?
The three layers of the adrenal cortex are: Microscopic view of the adrenal cortex: The layers of the adrenal gland cortex, zona glomerulosa (ZG), fasciculata (ZF), and reticularis (ZR), responsible to produce aldosterone, cortisol, and sex steroid hormone.

The adrenal medulla is responsible for producing catecholamines, or adrenaline type hormones such as epinephrine and norepinephrine. We have all experienced that sudden panic feeling and anxiety when something happens suddenly and unexpectedly and we get scared.
How much cortisol is produced in the adrenal gland?
Each day the adrenal glands secrete 15–20 mg of cortisol, 25–30 mg of androgens, and 75–125 µg of aldosterone. The mineralocorticoid aldosterone is produced in the outermost layer of the adrenal cortex, the zona glomerulosa. Aldosterone secretion is primarily controlled through a renal pathway.
Which layer of the adrenal cortex produces the most aldosterone?
The zona glomerulosa (ZG) is the most superficial layer of the adrenal cortex and it produces the hormone aldosterone as well as some small amounts of progesterone (a sex hormone). The mineralocorticoid aldosterone is produced here. The zona fasciculata (ZF) is the middle zone of the adrenal cortex, and it primarily produces cortisol.
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.

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 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.
Why do adrenal glands cause imbalances?
The two common ways in which adrenal glands cause health issues are by producing too little or too much of certain hormones, which leads to hormonal imbalances. These abnormalities of the adrenal function can be caused by various diseases of the adrenal glands or the pituitary gland.
What hormone is produced by the zona fasciculata?
Cortisol is a glucocorticoid hormone produced by the zona fasciculata that plays several important roles in the body. It helps control the body’s use of fats, proteins and carbohydrates; suppresses inflammation; regulates blood pressure; increases blood sugar; and can also decrease bone formation.

Why do adrenal glands have problems?
Adrenal gland disorders are caused by problems with the glands themselves that cause overproduction or underproduction of hormones. They are also caused by problems in other glands, such as the pituitary gland. Genetics can also play a part in certain adrenal disorders. In many cases, no one really knows why the disorders develop.
Why does adrenal insufficiency occur?
Adrenal insufficiency happens when the adrenal glands don’t produce enough cortisol and sometimes aldosterone. The production decreases when the adrenal cortex (the glands’ outer layer) is destroyed. This occurs most often when you have an autoimmune disease that causes your body to attack the glands.

Overview
The cortex is the outer part of your adrenal gland. It releases hormones that support your well-being.
Function
The adrenal cortex produces hormones that support vital organ functioning. Each adrenal cortex layer produces different hormones.
Anatomy
You have two adrenal glands — one on top of each kidney. They contain the cortex, the largest part of the gland, and the medulla, the smaller inner part. Your adrenal gland is highly vascular, with as many as 50 arterial branches providing its blood supply.
Conditions and Disorders
There are many conditions and disorders, some of which are rare, that can affect the adrenal cortex. These conditions can be functional, meaning they cause abnormally high hormone levels or nonfunctional, meaning they do not produce hormones.
