Addison’s disease and adrenal insufficiency are rare and life-threatening endocrine conditions, but can be treated by taking daily medication to replace the hormones that are missing. 

With the right balance of daily medication, people with Addison’s and adrenal insufficiency can expect to have a normal life span

The adrenal gland is a small gland that sits above your kidneys and produces vital steroid hormones that are essential for life and keep our body functioning correctly in many different ways. It is part of the body's endocrine (hormone) system.

Adrenal insufficiency describes when not enough of those vital hormones are produced, or they are no longer produced at all.

The 3 key hormones produced by the adrenal gland are cortisol, aldosterone and DHEA

What hormones are affected, and to what degree, depends on what type of adrenal insufficiency you have.   We have information on all three types of adrenal insufficiency.  Make sure to ask your doctor if you are not sure which type you have.

Types of adrenal insufficiency

Addison's disease (Primary adrenal insufficiency)

Named after Thomas Addison, the London doctor who first identified the condition, Addison's disease is also known as Primary adrenal insufficiency. It is a rare condition where the adrenal glands themselves stop working, so are unable to produce any of the essential hormones they usually would.

Secondary adrenal insufficiency

This is when the pituitary gland in the brain no longer sends the right signals to the adrenal glands to produce essential hormones, primarily cortisol.

Tertiary adrenal insufficiency

This is where the adrenal glands are suppressed (go to sleep) after taking long-term steroid medication for another condition.

Signs & Symptoms

People with adrenal insufficiency often report similar symptoms, regardless of which type they have. However, there are also some specific signs associated just with Addison's disease.

Diagnosis

Diagnosis is done by hospital blood tests and an assessment of the symptoms. Suspected cases will be referred to see an endocrinologist, a doctor who specialises in treating hormone-related conditions.

Newly diagnosed?

Whether you have just been diagnosed, or have had adrenal insufficiency for some time, knowledge is power! Let us guide you through the key information that will support you to be aware, be prepared and be understood.

What is an adrenal crisis?

An adrenal crisis is a life-threatening medical emergency that occurs when the cortisol levels in the body are too low for it to continue to function. 

Adrenal crisis can occur with any type of adrenal insufficiency.

It requires a time-critical emergency treatment with an injection (or IV) of hydrocortisone (chemically the same as cortisol) to raise cortisol levels in the body.
