Acute Adrenal Crisis: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 2, 2026.
What kind of doctor treats Acute Adrenal Crisis?
An endocrinologist usually manages adrenal insufficiency over the long term, while emergency medicine doctors treat the crisis itself. A primary care doctor often coordinates care. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is acute adrenal crisis?
Acute adrenal crisis is a medical emergency. It happens when the adrenal glands, which are small glands sitting on top of each kidney, suddenly stop making enough cortisol. Cortisol is a hormone that helps the body handle stress. It also keeps blood pressure steady and controls blood sugar. Without quick treatment, blood pressure can drop to dangerous levels.
In an adrenal crisis, the body cannot make the extra cortisol it needs during stress, and the person becomes very sick very fast. It is sometimes called an addisonian crisis, because it can happen in people with Addison's disease, in which the adrenal glands are damaged.
Symptoms
Symptoms usually come on quickly and worsen over hours: severe weakness, nausea, vomiting, and pain in the belly, lower back, or legs. Blood pressure may fall so low that the person feels dizzy, confused, or faints. Fever, very low blood sugar, and darker-looking skin can also appear.
Causes and who gets it
The most common cause is Addison's disease that has not been diagnosed or treated well. Stopping steroid medicines such as prednisone suddenly can also trigger a crisis, as can severe infection, surgery, injury, or dehydration.
How doctors diagnose it
Doctors often start treatment before test results come back, because waiting can be dangerous. Blood tests measure cortisol, sodium, potassium, and blood sugar, and a CT scan may follow once the person is stable.
Treatment
Treatment starts right away, usually in an emergency room, with an intravenous steroid and fluids to raise blood pressure. Doctors also treat the trigger, such as an infection. After recovery, most people need daily hormone replacement and an emergency steroid injection plan.
When to see a doctor
A person with severe vomiting, extreme weakness, confusion, or fainting should call 911 right away. Anyone with known adrenal insufficiency who cannot keep medicine down should also seek emergency care; less urgent concerns can go to a regular doctor.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can help manage adrenal insufficiency between emergencies and would send the patient to the emergency room during a crisis.
Common questions
Can adrenal crisis be prevented?
Often yes. People with adrenal insufficiency can lower their risk by taking their medicines as prescribed. They should never stop steroid medicines suddenly without a doctor's guidance. They can also ask their doctor about raising their dose during illness or before surgery.
Is adrenal crisis the same as Addison's disease?
No. Addison's disease is a long-term condition in which the adrenal glands do not make enough hormones. An adrenal crisis is a sudden, dangerous worsening that can happen in people with Addison's disease or other causes of low cortisol.
What should a person with adrenal insufficiency carry with them?
Many doctors recommend a medical alert bracelet or necklace and a card that says the person needs steroid medicine. Some people also carry an emergency steroid injection kit prescribed by their doctor.
Can adrenal crisis be fatal?
Yes, it can be, if it is not treated quickly. With prompt treatment in a hospital, most people recover, though outcomes vary from person to person.
