Adrenal crisis; Addisonian crisis; Acute adrenal insufficiency
Acute adrenal crisis is a life-threatening condition that occurs when there is not enough cortisol. This is a hormone produced by the adrenal glands.
The adrenal glands are located just above the kidneys. The adrenal gland consists of two parts. The outer portion, called the cortex, produces cortisol. This is an important hormone for controlling blood pressure. The inner portion, called the medulla, produces the hormone adrenaline (also called epinephrine). Both cortisol and adrenaline are released in response to stress.
Cortisol production is regulated by the pituitary. This is a small gland just underneath the brain. The pituitary releases adrenocorticotropic hormone (ACTH). This is a hormone that causes the adrenal glands to release cortisol.
Adrenaline production is regulated by nerves coming from the brain and spinal cord and by circulating hormones.
Adrenal crisis can occur from any of the following:
Symptoms and signs of adrenal crisis can include any of the following:
Tests that may be ordered to help diagnose acute adrenal crisis include:
In adrenal crisis, you need to be given the drug hydrocortisone right away through a vein (intravenous) or muscle (intramuscular). You may receive intravenous fluids if you have low blood pressure.
You will need to go to the hospital for treatment and monitoring. If infection or another medical problem caused the crisis, you may need additional treatment.
Many people with primary or secondary adrenal insufficiency have an emergency syringe with hydrocortisone at home that a family member can inject into muscle (IM) if they are too sick or too weak to take their hydrocortisone pills.
Shock may occur if treatment is not provided early, and it can be life threatening from very low blood pressure and heart problems.
Go to the emergency room or call the local emergency number (such as 911) if you develop symptoms of acute adrenal crisis.
Call your health care provider if you have Addison disease or hypopituitarism and are unable to take your glucocorticoid medicine for any reason.
If you have Addison disease, you will usually be told to temporarily increase the dosage of your glucocorticoid medicine if you are stressed or ill, or before having surgery. This is called 'stress' or 'sick-day' dosing.
If you have Addison disease, learn to recognize the signs of potential stress that may cause an acute adrenal crisis. If you have been instructed by your doctor, be prepared to give yourself an emergency shot of glucocorticoid or to increase your dosage of oral glucocorticoid medicine in times of stress. Parents should learn to do this for their children who have adrenal insufficiency.
Always carry medical ID (card, bracelet, or necklace) that says you have adrenal insufficiency. The ID should also say the type of medicine and dosage you need in case of an emergency.
If you take glucocorticoid medicines for pituitary ACTH deficiency, be sure you know when to take a stress dose of your medicine. Discuss this with your provider.
Never miss taking your medicines.
