Other conditions related to primary adrenal deficiency are:. Treatment for primary adrenal deficiency is with glucocorticoid cortisol and mineralocorticoid aldosterone replacement, for life. It is caused when the pituitary gland is unable to produce enough ACTH adrenocorticotropic hormone , which means the adrenal glands aren't prompted to secrete cortisol. Hypothalamic disease may also lead to adrenal insufficiency.
This is known as tertiary adrenal insufficiency, although often pituitary and hypothalamic causes are sometimes referred to together as secondary adrenal insufficiency. Causes of secondary adrenal insufficiency may include:. If untreated, an Addisonian crisis can be fatal. It may be caused by:. Not all symptoms occur on all occasions, but nausea, fatigue and dizziness are common early symptoms.
If you experience symptoms of Addisonian crisis, call for an ambulance or go immediately to the emergency department of your nearest hospital.

Note: even if you use a hydrocortisone injection for Addisonian crisis, you will still need hospitalisation and ongoing monitoring. Treatment aims to correct the levels of hormones that your body is not producing. Whether you have primary or secondary adrenal insufficiency, you will need hormone replacement for life. Cortisol is replaced orally with hydrocortisone tablets, taken once or twice a day. If you are also deficient in aldosterone, it is replaced with oral doses of a mineralocorticoid called fludrocortisone acetate, taken once a day.
Treatment needs to be tailored to each person as adrenal hormone replacement requirements vary between individuals.
Your doctor will advise you on how to reduce the risk of Addisonian crisis, including how to adjust your medication if your body is stressed for example due to an operation or illness and how to use injectable hydrocortisone if you are vomiting and unable to keep down oral medications. They will also advise you on how to let emergency medical personnel know what kind of care you need. This may include:.

Secondary adrenal insufficiency is more common, affecting to people per million. Secondary adrenal insufficiency occurs in people with certain conditions that affect the pituitary. People who take glucocorticoid medicines, such as prednisone, for a long time and then stop are most likely to develop tertiary adrenal insufficiency.
These medicines are used to treat medical conditions such as asthma , rheumatoid arthritis , lupus , cancer, and inflammation, among others.
The most serious complication of adrenal insufficiency is called adrenal crisis. If not treated right away, adrenal crisis can cause death. Your body needs much more cortisol than usual during times of physical stress such as illness, serious injury, or surgery. The severe lack of cortisol at these times can cause life-threatening low blood pressure, low blood glucose, low blood sodium, and high blood potassium.
Hyponatremia can cause confusion, fatigue, and muscle twitches and seizures. The lack of aldosterone can also cause hyperkalemia, or too much potassium. Mild hyperkalemia may not cause problems, but severe hyperkalemia can cause life-threatening changes in your heart rhythm.
