Causes of Addison's disease

Addison's disease results when your adrenal glands are broken, manufacturing insufficient amounts of the hormone cortisol and infrequently aldosterone similarly. These glands are located simply higher than your kidneys. As a part of your endocrine system, they turn out hormones that offer directions to nearly each organ and tissue in your body.

Your adrenal glands are composed of 2 sections. the inside (medulla) produces adrenaline-like hormones. The outer layer (cortex) produces a bunch of hormones referred to as corticosteroids, that embrace glucocorticoids, mineralocorticoids and male sex hormones (androgens).

Some of the hormones the cortex produces are essential forever — the glucocorticoids and therefore the mineralocorticoids.

• Glucocorticoids. These hormones, that embrace cortisol, influence your body's ability to convert food fuels into energy, play a task in your immune system's inflammatory response and facilitate your body answer stress.
• Mineralocorticoids. These hormones, that embrace aldosterone, maintain your body's balance of sodium and potassium to stay your blood pressure traditional.
• Androgens. These male sex hormones are made in little amounts by the adrenal glands in each men and ladies. They cause sexual development in men and influence muscle mass, libido and a way of well-being in men and ladies.

Primary adrenal insufficiency
Addison's disease happens when the cortex is broken and does not turn out its hormones in adequate quantities. Doctors confer with the condition involving harm to the adrenal glands as primary adrenal insufficiency.

The failure of your adrenal glands to provide adrenocortical hormones is most typically the results of the body attacking itself (autoimmune disease). For unknown reasons, your immune system views the adrenal cortex as foreign, one thing to attack and destroy.
 Other causes of adrenal gland failure might include:

• Tuberculosis
• different infections of the adrenal glands
• unfold of cancer to the adrenal glands
• Bleeding into the adrenal glands

Secondary adrenal insufficiency
Adrenal insufficiency may occur if your pituitary gland is diseased. The pituitary gland makes a hormone referred to as adrenocorticotropic hormone (ACTH),

that stimulates the adrenal cortex to provide its hormones. Inadequate production of ACTH will cause insufficient production of hormones normally made by your adrenal glands, albeit your adrenal glands are not broken. Doctors decision this condition secondary adrenal insufficiency.

Another additional common reason behind secondary adrenal insufficiency happens when folks that take corticosteroids for treatment of chronic conditions, like asthma or arthritis, abruptly stop taking the corticosteroids.

Addisonian crisis
If you've got untreated Addison's disease, an addisonian crisis could also be provoked by physical stress, like an injury, infection or illness.
