Adrenal Crisis - A Guide for EMT Students


1. DEFINITION

Adrenal crisis (also called Addisonian crisis or acute adrenal insufficiency) is a life-threatening medical emergency in which the body cannot produce enough cortisol to meet the physiological demands placed upon it. It occurs when already-marginal adrenocortical function is overwhelmed by an acute physiologic stressor, or when a patient with known adrenal insufficiency has their steroid replacement interrupted or inadequate.
The core problem: without sufficient cortisol (and often aldosterone), the body loses its ability to maintain blood pressure, blood sugar, fluid balance, and vascular tone - all simultaneously.
  • Tintinalli's Emergency Medicine, p. 1499
  • Sabiston Textbook of Surgery, p. 1563

2. CAUSES

Underlying Conditions (Who is at risk?)

Primary Adrenal Insufficiency (adrenal gland failure / Addison's disease)
  • Autoimmune adrenalitis (most common cause in developed countries)
  • Tuberculosis or fungal infection destroying the glands
  • Bilateral adrenal hemorrhage (Waterhouse-Friderichsen syndrome - classically from meningococcal sepsis)
  • HIV/AIDS-related adrenal destruction
  • Adrenal metastases
Secondary Adrenal Insufficiency (pituitary failure)
  • Pituitary tumors, apoplexy (sudden hemorrhage), or surgical removal
  • Traumatic brain injury / severe head trauma
  • Autoimmune hypophysitis
  • Radiation to the pituitary
Tertiary Adrenal Insufficiency (HPA axis suppression - most common cause EMTs will encounter)
  • Abrupt withdrawal or missed doses of chronic corticosteroid therapy - this is by far the most common trigger EMTs will see. Any patient on long-term prednisone, dexamethasone, or similar drugs is at risk.

Crisis Precipitants (Triggers - what pushes a vulnerable patient into crisis?)

  • Infection - the most common trigger, especially gastrointestinal infections
  • Severe physical illness, trauma, or burns
  • Major surgery
  • Extreme physical exertion
  • Acute cardiovascular event (MI, stroke)
  • Missed or vomited steroid doses
  • Certain medications (checkpoint inhibitors, etomidate, ketoconazole)
EMT Pearl: Always ask patients who look "sick but you can't explain why" if they take steroids or have a steroid emergency card/bracelet.
  • Tintinalli's Emergency Medicine, p. 1499
  • Harrison's Principles of Internal Medicine 22E (2025), p. 1285

3. SIGNS & SYMPTOMS

Adrenal crisis is notorious for non-specific, vague symptoms that mimic many other conditions - especially sepsis and acute abdomen.

Cardinal Signs of Acute Crisis

SystemFindings
CardiovascularProfound hypotension (often refractory to IV fluids and vasopressors), tachycardia, shock
GISevere nausea, vomiting, diarrhea, diffuse abdominal pain (can mimic acute abdomen)
NeurologicalConfusion, disorientation, lethargy, progressing to stupor and coma
MetabolicHypoglycemia, hyponatremia, hyperkalemia (in primary AI)
TemperatureFever may be present, even without obvious infection
SkinBronze hyperpigmentation (primary AI only - due to elevated ACTH); look at mucous membranes, palmar creases, scars

Differentiating Primary vs. Secondary (helpful in-hospital, less critical in the field)

FeaturePrimary AISecondary AI
HyperpigmentationYES (high ACTH)No
HypotensionMarkedLess severe unless in crisis
PotassiumHIGH (hyperkalemia)Low or normal
SodiumLOW (hyponatremia)Variable
Salt cravingCommonLess common

The "Great Mimic" Warning

Adrenal crisis frequently mimics:
  • Septic shock
  • Acute abdomen / surgical emergency
  • Neurological emergency (confusion, coma)
If a patient has unexplained shock that does not respond to fluids and you cannot find another cause - think adrenal crisis. - Tintinalli's Emergency Medicine, p. 1500

4. CLINICAL ASSESSMENT (Prehospital Focus for EMTs)

Scene Size-Up & Dispatch Clues

  • Patient found unresponsive, hypotensive, with vomiting/abdominal pain
  • History of Addison's disease, pituitary disease, or chronic steroid use
  • Steroid alert card, medic-alert bracelet, or home emergency injection kit

Primary Survey (ABCDE)

Airway: Assess and maintain - altered mental status may compromise airway.
Breathing: Usually intact, may be rapid (compensatory tachypnea from shock).
Circulation:
  • Hypotension (often systolic < 90 mmHg) - the hallmark finding
  • Tachycardia
  • Poor perfusion: pale/mottled skin, delayed capillary refill, weak rapid pulse
  • Look for signs of dehydration
Disability (neurological):
  • GCS - assess level of consciousness
  • Blood glucose (capillary/fingerstick) - hypoglycemia is common and immediately treatable
  • Pupils
Exposure:
  • Look for medic-alert bracelets/necklaces, wallet cards, steroid emergency card
  • Look for hyperpigmentation (bronze skin, dark mucous membranes)
  • Look for evidence of steroid use (cushingoid appearance, steroid inhalers/tablets at scene)

Key History Questions (SAMPLE - from patient, bystanders, or medical alert)

  • Known Addison's disease or adrenal insufficiency?
  • Currently taking corticosteroids (prednisone, hydrocortisone, dexamethasone, etc.)?
  • Missed any doses recently? Vomited their morning medication?
  • Recent illness, infection, injury, or surgery?
  • Do they carry an emergency hydrocortisone injection kit?

Red Flags Pointing to Adrenal Crisis

  • Unexplained hypotension not responding to IV fluids
  • Hypoglycemia in a non-diabetic
  • History of chronic steroid use + acute illness
  • Altered mental status with no other clear cause
  • Abdominal pain + hypotension without obvious surgical cause

5. MANAGEMENT

The EMT Priorities: ABCs + Early Recognition + Rapid Transport

The Golden Rule: Do not delay treatment waiting for lab confirmation. Treat based on clinical suspicion.
  • Tintinalli's Emergency Medicine, p. 1501; ISMP Canada Safety Bulletin, 2025

Step-by-Step Prehospital Management

1. Airway & Breathing
  • Ensure patent airway; consider positioning
  • Apply supplemental oxygen (SpO2 target ≥ 94%)
  • Be prepared to support ventilation in obtunded patients
2. Circulation - IV Access & Fluids
  • Establish large-bore IV access (2 lines if possible)
  • Normal saline (0.9% NaCl) is the fluid of choice - aggressive resuscitation
  • If hypoglycemic: administer dextrose-containing saline (D5NS) or dextrose bolus per protocol
  • Target: begin correcting hypotension
  • Typical hospital protocol: 2-3 liters NS in the first 6 hours
3. Blood Glucose
  • Obtain capillary blood glucose immediately
  • Hypoglycemia is common and rapidly correctable in the field
  • Give IV dextrose (D50W 25g in adults, or D10W in pediatrics) per protocol if glucose is low
4. Corticosteroid Administration This is the definitive life-saving treatment - check your local protocols, as some Advanced EMT / paramedic-level scopes include this:
DrugDoseRouteNotes
Hydrocortisone100 mg IV bolusIV (preferred) or IMDrug of choice - provides both glucocorticoid AND mineralocorticoid effect
Hydrocortisone100 mg IMIM into deltoid/thighIf no IV access
Dexamethasone4 mg IVIVAlternative if ACTH stimulation test planned in-hospital; does NOT have mineralocorticoid effect
Follow-up (in-hospital): 200 mg/24h infusion OR 50-100 mg IV every 6-8 hours.
EMT Note: Basic EMTs typically cannot administer hydrocortisone. Your role is to recognize the crisis, treat hypoglycemia, administer IV fluids, and transport rapidly. Some patients carry their own hydrocortisone auto-injector (like Solu-Cortef) and may self-administer or need assistance.
5. Vasopressors (ALS/Hospital)
  • Only used AFTER steroid therapy has been given
  • Norepinephrine, dopamine, or phenylephrine if shock persists despite fluids + steroids
  • Vasopressors are relatively ineffective without adequate cortisol replacement because cortisol is required for catecholamine sensitivity
6. Monitor & Reassess
  • Continuous cardiac monitoring (ECG changes from hyperkalemia)
  • Repeat vital signs every 5 minutes in unstable patients
  • Blood glucose monitoring
7. Treat Precipitating Cause
  • If infection suspected: alert receiving hospital for antibiotics
  • Identify and communicate any known triggers to receiving team
8. Rapid Transport
  • All confirmed or suspected adrenal crisis patients require ICU admission
  • Pre-notify the receiving facility - this is a time-critical emergency

If Patient Has a Home Emergency Injection Kit

Many patients with known Addison's disease carry an emergency hydrocortisone injection kit (Solu-Cortef Act-O-Vial, 100 mg). They or a caregiver may have already self-injected. If not, and if within your scope, assist administration per your medical director's protocols.

6. SUMMARY - ADRENAL CRISIS AT A GLANCE

SUSPECT IT when:
  → Unexplained hypotension/shock
  → Known steroid user + acutely ill
  → Steroid medic-alert card or bracelet
  → Hypoglycemia without clear cause

ASSESS:
  → ABCDE + fingerstick glucose
  → Scene clues (medications, alert cards)
  → Hyperpigmentation? (primary AI)

TREAT (prehospital):
  1. Airway + O2
  2. IV Normal Saline (aggressive)
  3. Dextrose if hypoglycemic
  4. Hydrocortisone 100 mg IV/IM (if in scope)
  5. Rapid transport → ICU
  6. Pre-notify hospital

DO NOT:
  → Wait for labs before treating
  → Give vasopressors before steroids
  → Forget to look for the precipitating cause

Key References


Note for EMT Scope of Practice: Corticosteroid administration is typically within the Paramedic or AEMT scope. Basic EMTs should focus on recognition, airway management, IV fluid therapy, dextrose for hypoglycemia, and rapid transport with early notification. Always follow your local medical director's protocols and standing orders.

Excellent - I have everything needed. Here is the comprehensive pathophysiology response.

Pathophysiology of Adrenal Crisis


Step 1 - Normal HPA Axis: The Foundation

To understand what goes wrong in adrenal crisis, you first need to understand what should happen under stress.
The Hypothalamic-Pituitary-Adrenal (HPA) axis is the body's central stress-response system:
STRESS / STRESSOR
       ↓
Hypothalamus → releases Corticotropin-Releasing Hormone (CRH)
       ↓
Anterior Pituitary → releases ACTH (adrenocorticotropic hormone)
       ↓
Adrenal Cortex → produces CORTISOL + ALDOSTERONE
       ↓
Negative feedback back to hypothalamus & pituitary (keeps levels in check)
The adrenal cortex has three zones, each producing different hormones:
ZoneHormone ProducedFunction
Zona Glomerulosa (outer)Aldosterone (mineralocorticoid)Regulates Na+/K+, fluid balance, BP
Zona Fasciculata (middle)Cortisol (glucocorticoid)Stress response, glucose, BP support
Zona Reticularis (inner)Androgens (DHEA)Sex hormone precursors
HPA axis and causes of adrenal insufficiency - Rosen's Emergency Medicine
Fig. 117.3 - Rosen's Emergency Medicine: HPA axis and pathways leading to adrenal insufficiency

Step 2 - What Cortisol Normally Does (Why Its Absence is Lethal)

Cortisol is not just a "stress hormone" - it performs essential moment-to-moment functions that sustain life:

A. Glucose Homeostasis

  • Stimulates gluconeogenesis (making new glucose in the liver from amino acids and glycerol)
  • Promotes glycogenolysis (breaking down liver glycogen into glucose)
  • Inhibits peripheral glucose uptake, inducing mild insulin resistance
  • Net result: keeps blood glucose elevated during stress
Without cortisol → glucose production fails → HYPOGLYCEMIA
"In hypocortisolism, there is hypoglycemia." - Costanzo Physiology, 7th Ed., p. 438

B. Vascular Tone & Blood Pressure ("Permissive Effect")

This is the most clinically critical function for EMTs to understand:
  • Cortisol up-regulates alpha-1 adrenergic receptors on vascular smooth muscle
  • This makes blood vessels sensitive to catecholamines (norepinephrine, epinephrine)
  • Without this permissive effect, even high circulating catecholamines cannot maintain vasoconstriction
Without cortisol → arterioles cannot respond to catecholamines → vasodilatation → refractory hypotension → distributive shock
"Glucocorticoids exert a permissive and enhancing effect on catecholamine signaling by sensitizing arterial smooth muscle cells to beta-adrenergic stimulation... Cardiac contractility and peripheral vascular tone are thus maintained, explaining why the hemodynamic collapse that accompanies acute adrenal insufficiency can be remedied by glucocorticoid administration." - Sabiston Textbook of Surgery, p. 1560

C. ADH (Anti-Diuretic Hormone) Regulation

  • Cortisol normally suppresses ADH release
  • Low cortisol → ADH rises → kidneys retain free water → dilutes sodium in blood
Without cortisol → elevated ADH → water retention → HYPONATREMIA (dilutional)

D. Immune & Inflammatory Modulation

  • Cortisol suppresses excessive inflammatory cascades
  • Without cortisol, the inflammatory response goes unchecked
  • This contributes to fever, vasodilation, and organ dysfunction

Step 3 - What Aldosterone Normally Does

Aldosterone acts on the distal nephron (collecting tubule) of the kidney:
  • Promotes Na+ reabsorption from urine back into blood
  • In exchange, secretes K+ and H+ into urine
  • Net effect: retains sodium and water → maintains intravascular volume and blood pressure
Without aldosterone (primary AI only) → sodium is lost in urine → volume depletion → HYPOVOLEMIA + HYPERKALEMIA + METABOLIC ACIDOSIS
"Aldosterone deficiency results in salt losses and clinical hypovolemia. The hypovolemia may further stimulate ADH release. Finally, the aldosterone deficiency may also cause hyperkalemia." - Symptom to Diagnosis, 4th Ed., p. 7286-7287
Important: Aldosterone deficiency only occurs in primary adrenal insufficiency (the adrenal gland itself is destroyed). In secondary/tertiary AI, aldosterone production is preserved because it is regulated by the renin-angiotensin system (not by ACTH), so the fluid/electrolyte derangements are less severe.

Step 4 - The Pathophysiological Cascade of Adrenal Crisis

When adrenal hormone levels become critically insufficient - either suddenly (e.g., bilateral adrenal hemorrhage) or through a stressor overwhelming marginal reserves - a cascade of simultaneous failures occurs:
TRIGGER (infection, missed steroids, trauma, surgery...)

    Hypovolemic (no volume) +
    Cardiogenic (poor cardiac output)
    → REFRACTORY to IV fluids alone
    → REFRACTORY to vasopressors alone
    ──────────────────────────────────────

Step 5 - Why Crisis Becomes Lethal Without Treatment

The mechanism of death in untreated adrenal crisis follows from the above:
  1. Cardiovascular collapse - vasodilation + hypovolemia combine into profound shock that does not respond to IV fluids or vasopressors because cortisol is absent
  2. Hypoglycemia - brain glucose supply fails → seizures, coma, death
  3. Electrolyte catastrophe - severe hyponatremia causes cerebral edema; severe hyperkalemia causes fatal arrhythmias
  4. Metabolic acidosis - from tissue hypoxia (shock) + H+ retention (aldosterone loss)
  5. Renal shutdown - from severe hypovolemia/shock → acute kidney injury + azotemia (rising creatinine/BUN)

Step 6 - Primary vs. Secondary: Pathophysiology Differences

MechanismPrimary AI (Addison's)Secondary/Tertiary AI
Problem locationAdrenal gland itself destroyedPituitary or hypothalamus fails; or chronic steroid suppression
CortisolAbsentAbsent/deficient
AldosteroneAbsent (adrenal destroyed)Present (renin-angiotensin still works)
ACTHVery HIGH (pituitary tries to compensate, drives melanocyte stimulation)Low or normal
HyperpigmentationYES (ACTH stimulates melanocortin receptors in skin)No
HyperkalemiaYES (no aldosterone to excrete K+)Usually NO
Volume depletionSevere (dual: no cortisol + no aldosterone)Less severe (aldosterone intact)
Crisis severityTypically more severeCan be severe if stressor is large enough
"Adrenal crisis is usually seen in patients with Addison disease because of mineralocorticoid deficiency but can also present in patients with secondary or tertiary adrenal insufficiency who undergo severe physiologic stress." - Rosen's Emergency Medicine, p. 2577

Step 7 - Why Vasopressors Alone Don't Work (Critical EMT Concept)

This is a key prehospital concept: vasopressors (dopamine, norepinephrine) are largely ineffective without cortisol replacement because:
  • The catecholamine receptors on blood vessels are down-regulated without cortisol's "permissive" effect
  • You can push as much vasopressor as you want, but the vessel walls won't respond adequately
  • Only after hydrocortisone is given do vasopressors begin to work
This is why the treatment order matters: give steroids BEFORE or simultaneously with vasopressors, not after.

can you simplify and explain only adrenal crisis pathophysiology?

Here is a simplified, focused explanation of adrenal crisis pathophysiology only.

Adrenal Crisis - Simplified Pathophysiology


The Big Picture (One Sentence)

Adrenal crisis happens when the body suddenly runs out of cortisol (and sometimes aldosterone), and without these hormones, the body cannot maintain blood pressure, blood sugar, or fluid balance - leading to life-threatening shock.

Think of It Like This - A Simple Analogy

Imagine cortisol as the "engine oil" of your body's stress response.
  • The engine (your heart and blood vessels) can still run without oil for a short time
  • But under stress (infection, injury, missed medication), the engine seizes up completely
  • No matter how hard you press the accelerator (vasopressors), the engine won't respond
  • The only fix is to add the oil back (give hydrocortisone)

The Two Hormones That Fail

When the adrenal glands stop working properly, two hormones drop critically low:
HormoneIts Normal JobWhat Happens When It's Gone
CortisolKeeps blood pressure up, makes glucose, controls inflammationBlood pressure crashes, blood sugar drops, shock develops
AldosteroneKeeps sodium and water in the bodyBody loses salt and water - becomes severely dehydrated and volume-depleted

The Pathophysiology - Step by Step

1. The Trigger Hits

A stressor arrives - infection, missed steroid dose, trauma, surgery. The body screams for more cortisol to handle the stress. But the adrenal glands cannot respond. Cortisol levels stay critically low.

2. Blood Pressure Collapses (The Most Dangerous Part)

Cortisol has a "permissive effect" on blood vessels - it keeps the walls of arteries sensitive to adrenaline (catecholamines) so they can tighten up and maintain blood pressure.
Normal: Adrenaline → arteries tighten → Blood pressure maintained ✓

Crisis:  Adrenaline → arteries DO NOT respond → vasodilation → BP crashes ✗
This is why the shock in adrenal crisis is refractory - it does not respond to IV fluids alone, and vasopressors barely work without cortisol. The blood vessels are simply "deaf" to adrenaline.

3. Blood Sugar Drops (Hypoglycemia)

Cortisol's job during stress is to make glucose available by:
  • Telling the liver to make new glucose (gluconeogenesis)
  • Breaking down glycogen stores
Without cortisol → liver stops making glucose → blood sugar falls → brain is starved → confusion, seizures, coma

4. Salt and Water Are Lost (Volume Depletion)

Aldosterone tells the kidneys to hold onto sodium (salt). Where sodium goes, water follows.
Without aldosterone → kidneys dump sodium into urine → water follows → body loses fluid → hypovolemia (low blood volume) → worsens the hypotension even further
At the same time, potassium cannot be excreted properly: → Potassium builds up in the blood → HYPERKALEMIA → risk of dangerous heart arrhythmias

5. The Compound Crash

All three problems hit simultaneously and reinforce each other:
      Cortisol deficiency          Aldosterone deficiency
             │                              │
    ┌────────┴────────┐            ┌────────┴────────┐
    │                 │            │                 │
 No vascular     No glucose     Salt lost        K+ builds up
 tone            made           in urine              │
    │                 │            │            Arrhythmia
 Vasodilation    HYPOGLYCEMIA  HYPOVOLEMIA      risk
    │                              │
    └──────────────┬───────────────┘
                   │
          REFRACTORY SHOCK
          (blood pressure crashes
           and won't come back up
           with fluids alone)
                   │
           If untreated → DEATH

Why Treatment Works

Once you understand the pathophysiology, the treatment makes perfect sense:
ProblemCauseFix
Refractory shockNo cortisol → vessels can't respond to adrenalineHydrocortisone 100mg IV - restores vascular sensitivity
HypovolemiaAldosterone gone → salt/water lostNormal saline IV - replaces lost volume
HypoglycemiaNo cortisol → no gluconeogenesisDextrose IV - directly replaces missing glucose
The key point: giving hydrocortisone is not just replacing a hormone - it is literally restoring the ability of blood vessels to maintain blood pressure. That is why steroids must come before or alongside vasopressors, not after.

One-Line Summary Per Mechanism

  • No cortisol + stress = vessels go limp → shock
  • No cortisol = liver stops making glucose → hypoglycemia
  • No aldosterone = kidneys dump salt → dehydration + low BP + high potassium
  • All three at once = life-threatening emergency

what is adrenal crisis?

Based on the comprehensive research already conducted in this session, here is a clear, direct answer:

What is Adrenal Crisis?

Adrenal crisis (also called Addisonian crisis) is a sudden, life-threatening medical emergency in which the body has critically insufficient levels of cortisol - and sometimes aldosterone - to meet its physiological demands.

In Simple Terms

Your adrenal glands (two small glands sitting on top of your kidneys) normally produce cortisol - a hormone your body absolutely depends on to:
  • Keep your blood pressure up
  • Maintain blood sugar
  • Help your body cope with any kind of stress (illness, injury, surgery)
In adrenal crisis, this system completely fails. The body is hit by a demand it cannot meet, and it goes into collapse.

The Key Points

What failsCortisol production (and aldosterone in primary disease)
The resultShock, hypoglycemia, electrolyte imbalance
Who gets itPeople with adrenal insufficiency (Addison's disease), chronic steroid users, pituitary disease patients
What triggers itInfection, missed steroid doses, trauma, surgery, vomiting
How dangerousRapidly fatal if untreated - can kill within hours
The fixIV hydrocortisone + IV fluids + treat the trigger

A One-Sentence Definition

Adrenal crisis is an acute, life-threatening state of severe cortisol deficiency in which the body can no longer maintain blood pressure, blood sugar, or fluid balance - resulting in refractory shock and death if not treated immediately.

Who Is at Risk?

The three groups EMTs most commonly encounter:
  1. Known Addison's disease patients - their adrenal glands don't work at all; any illness or missed dose can tip them into crisis
  2. Chronic steroid users (prednisone, dexamethasone, etc.) - long-term steroids suppress the HPA axis; if they stop suddenly or get sick without increasing their dose, crisis can occur
  3. Acute adrenal destruction - bilateral adrenal hemorrhage (Waterhouse-Friderichsen syndrome from severe meningococcal sepsis), or traumatic brain injury affecting the pituitary

How to Remember It

Think of it as "the body running out of its own life support hormone."
Without cortisol:
  • Blood vessels go limp → shock
  • Liver stops making glucose → hypoglycemia
  • Kidneys dump salt → dehydration
All three happen at once, which is why patients crash so fast and why simple fluids or vasopressors alone won't save them - only hydrocortisone restores the body's ability to respond.

Definition of Adrenal Crisis


Adrenal crisis (also known as Addisonian crisis or acute adrenal insufficiency) is a sudden, acute, life-threatening endocrine emergency resulting from a critical deficiency of cortisol - and often aldosterone - in which the body is unable to maintain blood pressure, blood glucose, and fluid balance, leading to cardiovascular collapse and death if not treated immediately.

Definitions from Authoritative Sources

"Adrenal crisis is a life-threatening state caused by insufficient levels of cortisol. It can result from acute destruction of the hypothalamic-pituitary axis or the adrenal glands, or from acute stressors in the setting of underlying primary or secondary adrenal insufficiency."Tintinalli's Emergency Medicine
"Acute adrenal insufficiency, or adrenal crisis, is a life-threatening condition that typically occurs in individuals with already marginal adrenocortical function who are subjected to a significant acute physiologic stressor, such as infection or trauma."Sabiston Textbook of Surgery
"Acute adrenal insufficiency, also termed adrenal crisis, usually occurs after a prolonged period of nonspecific complaints and is more frequently observed in patients with primary adrenal insufficiency, due to the loss of both glucocorticoid and mineralocorticoid secretion."Harrison's Principles of Internal Medicine, 22nd Edition (2025)

Breaking Down the Definition

TermMeaning
AcuteSudden onset
Life-threateningCan be fatal within hours
Endocrine emergencyCaused by a hormone failure
Cortisol deficiencyThe body's stress hormone is critically low
Adrenocortical insufficiencyThe outer layer of the adrenal gland is failing
Physiologic stressorAny trigger - infection, trauma, missed medication, surgery

In One Simple Sentence for EMT Students

Adrenal crisis is a medical emergency where the adrenal glands suddenly fail to produce enough cortisol, causing the body to go into a life-threatening shock that will not respond to fluids or vasopressors alone - only hydrocortisone can reverse it.

causes of adrenal crisis

Based on the thorough research already completed in this session, here is a clear, organized breakdown of the causes of adrenal crisis.

Causes of Adrenal Crisis


How to Think About It

Adrenal crisis has two layers of cause:
  1. The underlying condition - what made the adrenal glands vulnerable in the first place
  2. The trigger/precipitant - what pushed the vulnerable patient into full crisis

LAYER 1 - Underlying Conditions (Who Is Already at Risk?)

A. Primary Adrenal Insufficiency (Adrenal Gland Itself Is Destroyed)

The adrenal gland cannot make cortisol OR aldosterone.
CauseDetails
Autoimmune adrenalitisMost common cause in developed countries. The immune system attacks and destroys the adrenal cortex (Addison's disease)
Tuberculosis (TB)Most common cause worldwide. TB bacteria infect and destroy both adrenal glands
Bilateral adrenal hemorrhageBleeding into both adrenal glands - classic cause is Waterhouse-Friderichsen syndrome (meningococcal sepsis)
HIV/AIDSOpportunistic infections (CMV, MAC, fungi) destroy adrenal tissue
Fungal infectionsHistoplasmosis, cryptococcosis - especially in immunocompromised patients
Cancer/MetastasesLung, breast, kidney cancers can spread to and destroy adrenal glands
LymphomaCan infiltrate adrenal tissue
Adrenal surgeryBilateral adrenalectomy - patient has no adrenal tissue left
Congenital adrenal hyperplasiaGenetic enzyme defect; adrenals cannot make cortisol
AdrenoleukodystrophyGenetic disorder; affects males; adrenal destruction

B. Secondary Adrenal Insufficiency (Pituitary Fails - No ACTH Signal)

The pituitary gland cannot produce ACTH, so the adrenal glands receive no signal to make cortisol. Aldosterone is preserved because it is controlled by a separate system (renin-angiotensin).
CauseDetails
Pituitary tumorsCompress or destroy ACTH-producing cells
Pituitary apoplexySudden hemorrhage or infarction of the pituitary - acute emergency
Traumatic brain injuryDamages the pituitary or hypothalamus
Pituitary/brain surgerySurgical removal or damage to pituitary
Autoimmune hypophysitisImmune attack on the pituitary; associated with pregnancy
Cranial radiationRadiation therapy for brain or pituitary tumors suppresses ACTH
Sheehan's syndromePituitary infarction after severe postpartum hemorrhage
Infiltrative diseasesSarcoidosis, tuberculosis, histiocytosis infiltrating the pituitary

C. Tertiary Adrenal Insufficiency - Most Common Cause EMTs Will Encounter

The hypothalamus is suppressed by long-term exogenous steroids - the HPA axis shuts down.
CauseDetails
Chronic corticosteroid therapyPrednisone, dexamethasone, methylprednisolone taken for weeks to months - HPA axis switches off
Abrupt steroid withdrawalPatient stops steroids suddenly; adrenal glands have "forgotten" how to work
Inhaled/topical steroidsHigh-dose, prolonged use can cause mild suppression (less common)
EMT Pearl: Any patient who takes or recently stopped taking oral steroids is at risk. Always ask about steroid use.

LAYER 2 - Precipitating Triggers (What Pushes Into Crisis?)

A patient with underlying adrenal insufficiency is vulnerable but stable - until a trigger hits. The trigger creates a sudden demand for cortisol the body cannot meet.

Most Common Triggers

TriggerWhy It Causes Crisis
Infection (especially GI)#1 most common trigger. Fever and illness massively increase cortisol demand
Missed or vomited steroid dosePatient cannot absorb their replacement medication
Gastroenteritis (vomiting/diarrhea)Cannot keep oral steroids down + fluid losses worsen hemodynamics
Surgery or invasive proceduresMajor physiologic stress; cortisol demand spikes
TraumaPhysical injury demands a cortisol surge the body cannot provide
Severe burnsExtreme metabolic stress
Acute myocardial infarctionCardiovascular stress overwhelms adrenal reserve
Extreme physical exertionPhysiologic demand exceeds supply
Pregnancy/childbirthHormonal and physiologic stress
Psychological extreme stressCan be sufficient in patients with very marginal reserves

Medications That Can Trigger Crisis

DrugMechanism
EtomidateSingle dose inhibits adrenal steroidogenesis (blocks cortisol synthesis) - important for EMTs/paramedics during RSI
KetoconazoleAntifungal that blocks adrenal steroid synthesis
RifampicinIncreases cortisol breakdown (used in TB treatment - ironic given TB is a cause)
Phenytoin / PhenobarbitalAccelerate cortisol metabolism
Immune checkpoint inhibitors(nivolumab, pembrolizumab) - immunotherapy drugs that cause autoimmune hypophysitis
Megestrol acetateHas steroid-like activity; on withdrawal can trigger crisis

CMV, MAC, fungi full form

AbbreviationFull FormWhat It Is
CMVCytomegalovirusA common herpes-family virus; harmless in healthy people but causes severe organ damage (including adrenal glands) in HIV/AIDS patients
MACMycobacterium Avium ComplexA group of bacteria related to TB; causes widespread infection in advanced HIV/AIDS, can destroy adrenal tissue
FungiNot an abbreviation - refers to fungal organisms, specifically:
Histoplasma capsulatum (Histoplasmosis)Fungal infection from soil/bird droppings; adrenal involvement common
Cryptococcus neoformans (Cryptococcosis)Fungal infection from bird droppings; common in HIV patients
Pneumocystis jirovecii (PCP)Causes pneumonia in HIV but can rarely affect adrenals

Simple summary: In HIV/AIDS patients, the immune system is too weak to fight off these normally manageable infections. CMV, MAC, and fungi then spread through the body and physically destroy the adrenal glands - leading to primary adrenal insufficiency and eventually adrenal crisis.

signs and symptoms of adrenal crisis

Based on the research already completed in this session, here is a clear, organized breakdown of signs and symptoms of adrenal crisis.

Signs & Symptoms of Adrenal Crisis


First - Know the Difference

Sign = something you can observe or measure (objective) Symptom = something the patient tells you they feel (subjective)

The Most Important Warning

Adrenal crisis is called "the great mimic" - its signs and symptoms are vague and non-specific. It can look exactly like:
  • Septic shock
  • Acute abdomen / surgical emergency
  • Neurological emergency
  • Simple gastroenteritis
This is why it is so often missed - and why history taking (asking about steroids, Addison's disease) is just as important as physical findings.

SYMPTOMS (What the Patient Reports)

General / Whole Body

SymptomWhy It Happens
Extreme fatigue and weaknessNo cortisol = cells cannot generate adequate energy
Anorexia (loss of appetite)Cortisol deficiency causes GI dysfunction
Weight lossChronic cortisol deficiency, protein catabolism fails
Salt cravingAldosterone deficiency - body desperately needs sodium
Dizziness / lightheadednessHypotension, especially on standing (orthostatic)

Cardiovascular

SymptomWhy It Happens
Syncope (fainting)Severe hypotension - not enough blood reaching brain
PalpitationsFrom electrolyte imbalance (hyperkalemia, hyponatremia)

Gastrointestinal (very common - often leads to misdiagnosis)

SymptomWhy It Happens
NauseaCortisol deficiency disrupts GI motility
VomitingSame mechanism; worsens dehydration and prevents oral meds
DiarrheaElectrolyte and motility disruption
Severe abdominal painCan mimic appendicitis or bowel obstruction
EMT Pearl: Abdominal pain + hypotension in a steroid user = think adrenal crisis until proven otherwise.

Neurological

SymptomWhy It Happens
HeadacheLow blood pressure, electrolyte imbalance
Confusion / disorientationHypoglycemia + hypotension starving the brain
LethargyGlobal metabolic failure
Decreased responsivenessBrain hypoperfusion and hypoglycemia worsening

Musculoskeletal

SymptomWhy It Happens
Muscle pain / crampsElectrolyte imbalance (hyponatremia, hyperkalemia)
Joint painCortisol deficiency - loss of anti-inflammatory effect
Low back pain / leg painCan occur in severe crisis (adrenal hemorrhage especially)

SIGNS (What You Observe and Measure)

Vital Signs - The Most Critical Findings

SignDetails
HypotensionSystolic BP often < 90 mmHg - the hallmark sign. Refractory to IV fluids
Orthostatic hypotensionBP drops significantly when patient sits or stands up
TachycardiaHeart races to compensate for low BP and low volume
FeverEven without obvious infection - cortisol normally suppresses inflammation
HypoglycemiaLow blood sugar on fingerstick - may be the first measurable clue
TachypneaRapid breathing - compensating for metabolic acidosis and shock

Skin Findings

SignDetailsWho Has It
Bronze / dark hyperpigmentationSkin, mucous membranes, lips, gums, palmar creases, old scars darkenPrimary AI only (high ACTH stimulates melanocytes)
Pale skinFrom shock, poor perfusionAny type
Mottled skinBlotchy discoloration - sign of severe shockAny type
Cool, clammy skinPoor perfusion stateAny type

Neurological Signs

SignDetails
Altered mental statusConfusion → agitation → stupor → coma as crisis progresses
Decreased GCSBrain is being starved of glucose and blood flow
SeizuresFrom severe hypoglycemia or hyponatremia

Cardiovascular Signs

SignDetails
Weak, rapid pulseThready pulse from low cardiac output
Prolonged capillary refill> 2 seconds - poor peripheral perfusion
Jugular venous distension absentVeins are flat - volume depleted

Progression of Symptoms (Early to Late)

EARLY                          MIDDLE                        LATE / CRITICAL
─────────                      ──────                        ───────────────
Fatigue                    →   Nausea/vomiting          →   Severe hypotension
Weakness                   →   Abdominal pain           →   Altered consciousness
Dizziness                  →   Worsening weakness       →   Coma
Anorexia                   →   Confusion begins         →   Seizures
Salt craving               →   Hypoglycemia             →   Cardiovascular collapse
                           →   Fever                    →   DEATH if untreated

Primary vs. Secondary - Signs That Differ

SignPrimary AI (Addison's)Secondary/Tertiary AI
HyperpigmentationYES - bronze skinNO - may be pale
HyperkalemiaYES (no aldosterone)NO (aldosterone intact)
HyponatremiaYES - salt wastingYES but less severe

What to Look For on Scene (Prehospital)

LOOK:       Medic-alert bracelet/necklace
            Steroid emergency card in wallet
            Bronze/dark skin, pale/mottled skin
            Altered mental status

FEEL:       Weak thready pulse
            Cool clammy skin

MEASURE:    BP → low, often < 90 systolic
            HR → fast
            BGL → low (hypoglycemia)
            SpO2 → may be low in severe shock

ASK:        "Do you take steroids?"
            "Do you have Addison's disease?"
            "Have you missed any doses?"
            "Have you been vomiting or had diarrhea?"

Signs & Symptoms of Adrenal Crisis

(Emergency-Focused - What You Will Actually See)


The One Thing to Remember First

Most patients will look like they are in septic shock with no obvious cause. The clue is their history - steroids, Addison's disease, or a missed dose.

What You Will Find in an Emergency

1. Severe Hypotension (Most Critical Finding)

  • Systolic BP often below 90 mmHg
  • Does not respond to IV fluids alone
  • Patient may be in obvious shock - pale, mottled, cold and clammy skin
  • Weak, rapid, thready pulse

2. Tachycardia

  • Heart rate fast and weak
  • The heart is racing to compensate for the collapsing blood pressure

3. Altered Mental Status

  • Ranges from confusion and disorientationlethargyunresponsive
  • Caused by the brain being starved of both blood and glucose simultaneously

4. Nausea, Vomiting & Abdominal Pain

  • Very common - present in most crisis patients
  • Abdominal pain can be severe, mimicking an acute abdomen
  • Vomiting makes everything worse - patient loses more fluids and cannot keep oral medications down

5. Hypoglycemia (Low Blood Sugar)

  • Check fingerstick glucose immediately on every patient
  • Patient may be sweating, shaking, confused, or unconscious
  • One of the most immediately treatable findings in the field

6. Extreme Weakness and Fatigue

  • Patient feels too weak to stand or sit up
  • Often described as "the worst they have ever felt"
  • May have collapsed or be found on the floor

7. Fever

  • Present even without obvious infection
  • Loss of cortisol removes the body's natural anti-inflammatory control

8. Bronze Skin Hyperpigmentation (Primary Addison's only)

  • Darkening of skin, lips, gums, and palmar creases
  • This is a scene clue - if you see it, adrenal crisis jumps to the top of your list

All Together - At a Glance

What You See / MeasureFinding
Blood pressureLow - often < 90 systolic, refractory
Heart rateFast - weak thready pulse
Mental statusAltered - confused, drowsy, or unresponsive
Blood glucoseLow - hypoglycemia
SkinPale, clammy, mottled - or bronze (Addison's)
GI complaintsNausea, vomiting, abdominal pain
General appearanceExtremely weak, collapsed
TemperatureFever may be present

The Emergency Memory Rule

Unexplained SHOCK  +  History of STEROIDS or ADDISON'S
           =  Adrenal Crisis until proven otherwise

Bottom line for EMTs: You will arrive to find a patient in shock - cold, hypotensive, tachycardic, confused, and vomiting - with no obvious cause. The moment you see a medic-alert bracelet, steroid medications at the scene, or a history of Addison's disease, treat it as adrenal crisis immediately.

Assessment of adrenal crisis

Assessment of Adrenal Crisis

EMT Prehospital Assessment Guide


The Golden Rule of Assessment

You will rarely diagnose adrenal crisis with certainty in the field. Your job is to SUSPECT it, assess systematically, and act fast.

STEP 1 - Scene Size-Up (Before You Touch the Patient)

Look around the scene for clues - this takes 10 seconds and can save a life.
LOOK FOR:
✔ Steroid medications (prednisone, dexamethasone, hydrocortisone tablets)
✔ Medic-alert bracelet or necklace ("Addison's disease" / "steroid dependent")
✔ Steroid emergency card in wallet or on fridge
✔ Emergency hydrocortisone injection kit at home
✔ Patient found collapsed or unable to get up
✔ Signs of recent vomiting or diarrhea
If you see any of these - adrenal crisis is immediately on your differential list.

STEP 2 - Primary Survey (ABCDE)

Life threats first - find and fix as you go


A - Airway

What to CheckWhat You May Find
Is the airway open and clear?May be compromised in altered/unconscious patients
Is the patient making abnormal sounds?Gurgling, snoring from decreased consciousness
Action: Open and maintain airway. Position appropriately. Suction if needed.

B - Breathing

What to CheckWhat You May Find
Rate and depth of breathingTachypnea (fast breathing) - compensating for shock/acidosis
SpO2May be low in severe shock
Chest rise and effortUsually adequate unless severely obtunded
Action: Apply supplemental oxygen. Target SpO2 ≥ 94%.

C - Circulation

What to CheckWhat You May Find
Blood pressureLow - often < 90 systolic. This is the cardinal finding
Heart rateFast and weak - tachycardia
Pulse qualityThready, weak, rapid
Skin colorPale, mottled, cyanotic
Skin temperatureCold and clammy
Capillary refillProlonged > 2 seconds
Jugular veinsFlat - volume depleted
Action: Establish IV access. Prepare for fluid resuscitation.

D - Disability (Neurological)

What to CheckWhat You May Find
GCS (Glasgow Coma Scale)Reduced - confusion to coma
AVPUAlert → Voice → Pain → Unresponsive
Blood glucose (fingerstick)LOW - hypoglycemia. Do this immediately
PupilsUsually normal; check for other causes
Action: Fingerstick glucose is mandatory. Treat hypoglycemia immediately if found.

E - Exposure

What to CheckWhat You May Find
Skin hyperpigmentationBronze/dark skin, dark gums, lips, palmar creases → Primary Addison's
Signs of traumaRule out other causes of shock
Rashes or skin changesClues to underlying condition
Cushingoid appearanceRound face, central obesity → suggests chronic steroid use
Medical alert devicesBracelet, necklace, tattoo

STEP 3 - History (SAMPLE)

Ask the patient, family, or bystanders

LetterQuestionWhat You Are Looking For
S - Signs & Symptoms"What happened? When did this start?"Sudden collapse, weakness, vomiting, abdominal pain
A - Allergies"Any allergies?"Important before giving any medications
M - Medications"Do you take steroids? Prednisone? Hydrocortisone?"Most important question
P - Past Medical History"Do you have Addison's disease? Pituitary problems? Cancer?"Known adrenal insufficiency
L - Last Oral Intake"When did you last eat? Have you been vomiting?"Hypoglycemia risk; inability to take oral steroids
E - Events"Did you miss any steroid doses? Have you had an infection, diarrhea, surgery recently?"Identifies the trigger

The 3 Most Important History Questions for Adrenal Crisis

1. "Do you take steroids or have you recently stopped taking them?"
2. "Have you been diagnosed with Addison's disease?"
3. "Have you missed any doses due to vomiting, illness, or forgetting?"

STEP 4 - Secondary Survey

Head-to-toe check for additional clues

AreaWhat to AssessFinding in Adrenal Crisis
Head/FaceSkin color, facial featuresPale or bronze skin; Cushingoid face if on steroids
EyesPupils, visual changesUsually normal
Mouth/GumsColor of mucous membranesDark pigmentation in primary AI
NeckJVD, medic-alert necklaceFlat neck veins (volume depleted)
ChestBreath sounds, chest wallUsually clear
AbdomenTenderness, guardingDiffuse abdominal pain/tenderness - can mimic surgical abdomen
SkinColor, temperature, moisturePale/mottled/clammy OR bronze hyperpigmentation
ExtremitiesMuscle weakness, IV accessProfound weakness; look for medic-alert bracelet

STEP 5 - Vital Signs (Reassess Every 5 Minutes in Unstable Patients)

Vital SignExpected FindingSignificance
Blood Pressure< 90 systolic, refractoryHallmark - distributive + hypovolemic shock
Heart Rate> 100, weak and threadyCompensatory tachycardia
Respiratory Rate> 20, shallowCompensating for metabolic acidosis
SpO2May be lowTissue hypoperfusion
TemperatureElevated (fever)Cortisol loss → inflammation unchecked
Blood Glucose< 70 mg/dL (< 3.9 mmol/L)Cortisol deficiency → no gluconeogenesis
GCSReduced from 15Brain hypoperfusion + hypoglycemia

STEP 6 - Red Flags That Demand Immediate Action

ANY ONE of these = treat as adrenal crisis NOW:

⚠ Unexplained hypotension not responding to fluids
⚠ Known steroid user who is acutely ill or collapsed
⚠ Medic-alert device saying "Addison's" or "steroid dependent"
⚠ Hypoglycemia with no history of diabetes
⚠ Severe abdominal pain + shock + steroid history
⚠ Altered mental status with no clear neurological cause
⚠ Bronze hyperpigmentation + collapse

Complete Assessment Summary

SCENE SIZE-UP
→ Steroid meds? Medic-alert? Emergency kit? Vomit?

PRIMARY SURVEY (ABCDE)
→ A: Airway open?
→ B: Breathing rate & SpO2
→ C: BP (low?), HR (fast?), perfusion (poor?)
→ D: GCS, AVPU, BLOOD GLUCOSE (mandatory)
→ E: Hyperpigmentation? Cushingoid? Medic-alert?

HISTORY (SAMPLE)
→ Taking steroids? Missed dose? Addison's?
→ Recent illness, vomiting, surgery, trauma?

VITAL SIGNS
→ BP, HR, RR, SpO2, Temp, BGL - every 5 min if unstable

RED FLAGS
→ Unexplained shock + steroid history = ADRENAL CRISIS

Final Assessment Principle for EMTs: You do not need to confirm the diagnosis - you need to recognize the pattern. Shock + steroid history + no obvious cause = act immediately, notify the hospital early, and transport fast.

Assessment of adrenal crisis

I just provided a detailed assessment guide in my previous response. Here is a concise, clean version focused purely on what an EMT does step by step on scene.

Assessment of Adrenal Crisis - EMT Quick Guide


The Mindset Before You Start

You will not diagnose adrenal crisis in the field. You will suspect it based on the pattern: unexplained shock + history of steroids or Addison's disease.

1. Scene Size-Up

Before touching the patient, scan the scene for 10 seconds:
  • Steroid medications nearby (prednisone, hydrocortisone, dexamethasone)
  • Medic-alert bracelet or necklace
  • Steroid emergency card
  • Home hydrocortisone injection kit
  • Signs of vomiting or diarrhea
  • Patient found collapsed and unable to get up

2. Primary Survey - ABCDE

StepWhat to CheckWhat You Find
AirwayOpen? Clear?May be compromised if unconscious
BreathingRate, SpO2Fast breathing, SpO2 may be low
CirculationBP, HR, pulse, skinLow BP, fast weak pulse, pale cold clammy skin
DisabilityGCS, AVPU, blood glucoseConfused to unresponsive; blood glucose LOW
ExposureFull skin checkBronze pigmentation, medic-alert device, Cushingoid appearance
Fingerstick blood glucose is mandatory in every suspected adrenal crisis patient.

3. History - SAMPLE

Focus on these key questions:
QuestionWhat You Are Looking For
"Do you take steroids?"Prednisone, hydrocortisone, dexamethasone
"Do you have Addison's disease?"Known adrenal insufficiency
"Did you miss any doses?"Missed or vomited steroid medication
"Have you been sick recently?"Infection is the #1 trigger
"Any recent surgery or injury?"Other major stressors

4. Vital Signs - Every 5 Minutes if Unstable

Vital SignExpected Finding
Blood PressureLow - often < 90 systolic
Heart RateFast - > 100, weak and thready
Respiratory RateFast and shallow
SpO2May be reduced
TemperatureFever possible
Blood GlucoseLow - hypoglycemia
GCSReduced

5. Red Flags - Act Immediately if Any Present

⚠ Unexplained shock not responding to fluids
⚠ Known steroid user who is acutely unwell
⚠ Medic-alert device for Addison's or steroid dependence
⚠ Hypoglycemia with no diabetes history
⚠ Severe abdominal pain + shock + steroid history
⚠ Altered mental status with no clear cause
⚠ Bronze skin + collapse
