Frequently asked questions

Autoimmune Addison’s disease happens when your immune system mistakenly attacks the outer layer of your adrenal glands. The damaged glands can’t make enough cortisol (the stress and energy hormone) and often aldosterone (the salt- and water-balance hormone). Without these hormones, people feel very tired, weak, lose weight, feel dizzy on standing, crave salt, and can have tummy pain; during illness or injury the body can’t raise cortisol, which can trigger a life-threatening adrenal crisis unless steroid medicine is given fast. Doctors diagnose it with morning blood cortisol/ACTH, an ACTH (cosyntropin) stimulation test, electrolytes, and often 21-hydroxylase antibodies that prove the autoimmune cause. Treatment is lifelong hormone replacement (glucocorticoid ± mineralocorticoid), education on “sick-day rules,” and emergency hydrocortisone for crises. NCBI+3NIDDK+3NIDDK+3

Autoimmune Addison’s disease (AAD) is a long-term condition in which the body’s own immune system attacks the adrenal glands. The adrenals are two small glands that sit on top of the kidneys. They normally make vital hormones: cortisol (helps you respond to stress, maintain blood pressure, blood sugar, and energy) and aldosterone (helps the body keep the right balance of salt and water). In AAD, slowly over months to years, immune cells and autoantibodies damage the adrenal cortex (the hormone-making outer layer). As the damage progresses, the glands can no longer make enough cortisol and, often, not enough aldosterone. This shortage causes symptoms like tiredness, weight loss, low blood pressure, salt craving, and skin darkening. If hormone levels drop suddenly or you get sick, you can develop an “adrenal crisis,” which is a medical emergency. Doctors confirm the diagnosis with hormone testing (especially an ACTH/cosyntropin stimulation test) and blood tests for adrenal autoantibodies, most commonly 21-hydroxylase (21-OH) antibodies.

Other names

Autoimmune Addison’s disease is also called:

Primary adrenal insufficiency (autoimmune type).
Autoimmune adrenalitis.
Idiopathic adrenal atrophy (older term, when cause was unknown but is now recognized as autoimmune in most cases).
Addison disease/Addison’s disease (eponym for chronic primary adrenal failure).
A component of Autoimmune Polyendocrine Syndrome type 1 (APS-1) or type 2 (APS-2) when it occurs with other autoimmune conditions. Oxford Academic+1

Types

Isolated AAD: The autoimmune attack is limited to the adrenals. People may only have adrenal symptoms. 21-OH antibodies are usually present early. PMC
AAD within APS-1: A rare, inherited syndrome (mutations in the AIRE gene) that typically begins in childhood, often with chronic mucocutaneous candidiasis and hypoparathyroidism; Addison’s may appear later. PubMed
AAD within APS-2: More common than APS-1; usually occurs in adults and clusters with autoimmune thyroid disease and/or type 1 diabetes. PubMed
Latent/pre-clinical autoimmune adrenalitis: 21-OH antibodies are detectable, but cortisol and aldosterone production may still be normal; risk of progressing to clinical Addison’s increases over time. PMC
Checkpoint-inhibitor–associated primary adrenalitis: Cancer immunotherapy (e.g., PD-1/PD-L1 or CTLA-4 inhibitors) can trigger autoimmune damage to adrenals, leading to primary adrenal insufficiency; evaluation also rules out other causes such as metastases or hemorrhage. ScienceDirect

Causes

Even though “autoimmune” means the body’s immunity turns against the adrenals, many factors can set the stage. Below are well-described causes, risks, and triggers linked to AAD.

Autoantibodies to 21-hydroxylase (21-OH): These are the hallmark immune markers and strongly linked to adrenal cortex destruction. PMC
Genetic susceptibility (HLA types): Certain HLA genes increase risk of organ-specific autoimmunity, including AAD. PMC
APS-2 background: Having autoimmune thyroid disease and/or type 1 diabetes increases likelihood of AAD as part of APS-2. PubMed
APS-1 (AIRE gene mutations): A strong inherited risk where Addison’s is a core feature. PubMed
Other immune-regulatory genes: Variants in immune checkpoints (e.g., CTLA-4, PTPN22) are associated with organ-specific autoimmunity clusters that include AAD (association data from autoimmune literature). PMC
Checkpoint inhibitor cancer therapy: Immune activation by drugs like nivolumab or pembrolizumab can trigger primary adrenal failure. ScienceDirect
Female sex (slight predominance): Many autoimmune diseases, including AAD, are more common in women. PMC
Other autoimmune diseases in the person or family: Thyroiditis, type 1 diabetes, celiac disease, pernicious anemia, vitiligo, etc., cluster with AAD. PubMed
Autoimmune “spreading” over time: Once one organ is targeted, new targets may appear later (observed in APS cohorts). PMC
Environmental triggers: Infections or stressors are suspected to unmask latent autoimmunity in genetically at-risk people (inferred from natural history studies). PMC
Age at diagnosis: Some studies note antibody patterns vary with age, suggesting timing influences disease expression. PMC
Adrenal-specific immune cell infiltration: T-cell–mediated destruction is part of the pathology in autoimmune adrenalitis. Oxford Academic
Cross-reactivity with adrenal enzymes: The immune system targets steroid-producing enzymes (e.g., 21-OH), causing progressive loss of hormone synthesis. PMC
Longstanding presence of 21-OH antibodies: People with persistent antibodies have a higher chance of progressing to clinical Addison’s. PMC
Checkpoint-inhibitor–related adrenalitis even without antibodies: Drug-induced immune damage can occur with or without classic antibodies. ScienceDirect
Association with celiac disease: Autoimmunity clusters; celiac is a recognized partner in APS-2. PubMed
Association with pernicious anemia: Autoimmune B12 deficiency commonly coexists within APS-2. PubMed
Association with vitiligo: Skin autoimmunity is a frequent comorbidity and potential clinical clue. PubMed
Association with autoimmune thyroid disease: Hashimoto’s or Graves’ disease often precede or follow AAD. PubMed
Association with type 1 diabetes: Part of the classic triad in APS-2; its presence should prompt adrenal screening when symptoms fit. PubMed

Symptoms

Extreme tiredness and weakness that doesn’t improve with rest, due to low cortisol and low blood pressure. Merck Manuals+1
Loss of appetite and unplanned weight loss, because cortisol deficiency reduces appetite and digestion. nhs.uk
Nausea, vomiting, or stomach pain, especially during stress or illness. American Academy of Family Physicians
Dizziness or light-headedness when standing (orthostatic hypotension) due to low aldosterone and salt loss. Merck Manuals
Craving for salty foods, because the body is trying to correct salt loss. nhs.uk
Skin darkening (hyperpigmentation) in sun-exposed areas, scars, skin folds, and gums; high ACTH stimulates skin pigment cells. Merck Manuals
Muscle aches, cramps, or weakness related to electrolyte imbalances. nhs.uk
Headache and a general “washed out” feeling. nhs.uk
Feeling very thirsty and peeing more (when salt and water balance is off). nhs.uk
Low mood, anxiety, or irritability, which often improve with correct hormone replacement. nhs.uk
Poor concentration or brain fog, especially during stress. nhs.uk
Low blood pressure all the time, not just when standing. Merck Manuals
Low blood sugar symptoms (shakiness, sweating, confusion), mainly in children or when fasting. Oxford Academic
Irregular periods or reduced libido, because adrenal steroids support overall hormone balance. Oxford Academic
Adrenal crisis signs during illness: severe weakness, vomiting, belly pain, low blood pressure, confusion—this is an emergency. endocrinology.org

Diagnostic tests

A) Physical exam

Blood pressure lying and standing: Doctors measure your BP while lying down and again after standing. A big drop suggests salt and water loss from low aldosterone. Merck Manuals
Skin and gum color check: Darkening of skin, new or deeper tanning, and gum hyperpigmentation point to primary (not secondary) adrenal failure. Merck Manuals
Weight and body mass: Unplanned weight loss is common in AAD. American Academy of Family Physicians
Signs of dehydration: Dry mouth, low skin turgor, and dizziness—clues to aldosterone deficiency. Oxford Academic
Look for other autoimmune clues: Vitiligo patches, thyroid enlargement, or B12 deficiency features hint at APS-2 and reinforce suspicion for AAD. PubMed

B) “Manual” bedside tests

Orthostatic vital signs: A simple bedside repeat of heart rate and BP after standing; a drop in BP and rise in pulse support volume depletion. Merck Manuals
Capillary refill and mucous membrane check: Slow refill and dry mucosa suggest dehydration from salt loss. Oxford Academic
Bedside glucose check: Low glucose during illness or fasting may be seen, especially in children. Oxford Academic
ECG monitoring at bedside: Can quickly reveal changes linked to high potassium (e.g., peaked T waves), which occur with aldosterone deficiency. NCBI
Sick-day steroid card/emergency plan review: Not a lab test, but checking whether a person at risk carries a steroid card or injection kit helps identify established AAD and crisis risk. endocrinology.org

C) Laboratory and pathology tests

Morning serum cortisol: A very low 8–9 AM cortisol suggests adrenal insufficiency; intermediate values require a stimulation test. UpToDate
ACTH (plasma): High ACTH with low cortisol indicates primary (adrenal) failure rather than pituitary causes. Oxford Academic
Standard ACTH (cosyntropin) stimulation test: The key confirmatory test; failure of cortisol to rise after ACTH confirms adrenal insufficiency. Endocrine+1
Electrolytes (sodium, potassium): Low sodium and high potassium are classic in AAD due to aldosterone deficiency. Merck Manuals
Plasma renin and aldosterone: High renin with low aldosterone supports primary adrenal failure affecting the zona glomerulosa. NCBI
21-hydroxylase autoantibodies: Presence strongly indicates autoimmune adrenalitis and helps distinguish AAD from other causes. PMC
Screen for other autoimmune conditions: TPO antibodies (thyroid), anti-GAD (type 1 diabetes), anti-parietal cell or intrinsic factor (pernicious anemia), celiac serology—important in APS-2. PubMed
Basic hematology and kidney profile: May show dehydration, mild anemia, or renal function changes during volume depletion; helps assess severity and crisis. Oxford Academic

D) Electrodiagnostic / monitoring tests

Electrocardiogram (ECG): Detects potassium-related changes (e.g., peaked T waves, widened QRS) in significant hyperkalemia from aldosterone deficiency, guiding urgent care. NCBI

E) Imaging tests

Adrenal CT or MRI: Imaging is not needed to diagnose classic autoimmune cases, but is helpful when the diagnosis is unclear, to exclude other causes (e.g., hemorrhage, infections, metastases), or in immune-checkpoint–treated patients. Chronic autoimmune destruction often shows small or normal-size adrenals; acute hemorrhage shows bulky, high-attenuation glands on CT.

Non-pharmacological treatments

Each item explains what it is, purpose, and mechanism/how it helps in plain English.

Self-education & care plan. Learn the symptoms, daily dosing schedule, and emergency steps. Purpose: reduce crisis risk. Mechanism: knowing when to increase steroids during fever, vomiting, surgery, or major stress prevents under-replacement when the body would normally raise cortisol. endocrinology.org+1
“Sick-day rules.” When you’re ill, increase your steroid dose (often double; specific emergency regimens exist) and hydrate. Purpose: mimic the normal stress rise of cortisol. Mechanism: prevents sudden cortisol shortage that can cause low blood pressure, shock, and crisis. endocrinology.org+1
Emergency steroid injection training. You (and family) learn to give IM hydrocortisone if you can’t keep pills down or feel worsening crisis. Purpose: buy time until medical care. Mechanism: rapid steroid raises cortisol to life-saving levels. addisonsdisease.org.uk
Medical alert ID (card/bracelet). Purpose: first responders know you need steroids immediately. Mechanism: speeds correct treatment in unconscious or confused states. endocrinology.org
Adequate salt and fluids. Especially if you lack aldosterone or in hot weather/exercise. Purpose: maintain blood volume and pressure. Mechanism: replaces sodium and water your body would conserve with aldosterone. Endocrine+1
Orthostatic blood pressure monitoring at home. Purpose: detect under-replacement (dizziness on standing). Mechanism: low volume/aldosterone causes a BP drop that you can track and report. Endocrine
Infection prevention habits (hand hygiene, prompt care). Purpose: infections are common crisis triggers. Mechanism: reduce intercurrent stressors that would otherwise demand higher cortisol. NCBI
Peri-procedure planning. Before dental work, endoscopy, or surgery, arrange stress-dose steroids and IV fluids. Purpose: avoid crisis during anesthesia and pain. Mechanism: scheduled hydrocortisone bolus/infusion mimics physiologic stress response. endocrinology.org
Heat management & hydration plan. Purpose: limit dehydration and salt loss in hot climates. Mechanism: replaces sweat-related sodium/water losses when aldosterone is low. NIDDK
Travel kit and letter. Keep spare pills, emergency injection, and translated instructions. Purpose: continuity of therapy. Mechanism: prevents missed doses and delays at security or clinics. endocrinology.org
Dietary regularity (don’t skip meals). Purpose: avoid hypoglycemia and nausea that impair pill absorption. Mechanism: steady carbohydrate intake complements cortisol replacement. NCBI
Stress-reduction techniques (sleep, pacing, CBT, mindfulness). Purpose: reduce avoidable stressors that would need dose increases. Mechanism: fewer cortisol-demand spikes. NCBI
Sick-day antiemetic access plan. Keep an approved anti-nausea medicine so you can retain oral steroids; if not possible, use IM hydrocortisone. Purpose/mechanism: maintain steroid levels despite vomiting. endocrinology.org
Regular follow-up with an endocrinologist. Purpose: tailor doses, check electrolytes/renin, review symptoms and BP. Mechanism: adjust glucocorticoid/mineralocorticoid to clinical targets. Endocrine
Screening for associated autoimmune diseases. Thyroid, type 1 diabetes, pernicious anemia, celiac, etc. Purpose: catch conditions that change dosing or nutrition. Mechanism: shared autoimmunity risk. NCBI
Flu and standard immunizations via primary care. Purpose: cut infection-triggered crises. Mechanism: reduce febrile illnesses that require stress dosing. (Routine vaccines per national schedules.) NCBI
Salt tablets or electrolyte solutions during heavy exertion. Purpose: quick sodium/water replacement when sweating. Mechanism: counters lack of aldosterone-mediated sodium conservation. Endocrine
Bp/weight diary. Purpose: flags edema (over-replacement with fludrocortisone) or weight loss/low BP (under-replacement). Mechanism: objective self-monitoring prompts dose review. Endocrine
Safe medication checklist. Some drugs affect steroid metabolism or blood pressure/ potassium; keep a list and ask before new meds. Purpose: avoid interactions that destabilize replacement. Mechanism: proactive review with clinicians. Endocrine
Household emergency script. Family knows to give IM hydrocortisone and call emergency services. Purpose: reduce treatment delay in crisis. Mechanism: rehearsed steps → faster lifesaving steroid delivery. addisonsdisease.org.uk

Drug treatments

Replacement is the core therapy. Doses are individualized—your endocrinologist will tailor them.

Hydrocortisone (first-line daily replacement). Class: short-acting glucocorticoid. Typical dose/time: 15–25 mg/day split 2–3 doses (e.g., morning largest, early afternoon smaller). Purpose: replace cortisol for energy, blood pressure support, glucose control. Mechanism: binds glucocorticoid receptors, restoring cortisol actions; short half-life reduces overexposure at night. Side effects (if too high): weight gain, insomnia, high BP, high glucose; if too low: fatigue, dizziness. Endocrine+2Oxford Academic+2
Fludrocortisone. Class: mineralocorticoid. Dose: often 0.05–0.2 mg once daily, individualized. Purpose: replaces aldosterone to hold sodium and water, excrete potassium. Mechanism: activates mineralocorticoid receptors in kidney to conserve salt/water and maintain BP. Side effects (excess): ankle swelling, high BP, low potassium; deficit: salt craving, dizziness, high potassium. Endocrine
Prednisolone (alternative daily glucocorticoid). Class: intermediate-acting glucocorticoid. Dose: commonly 3–5 mg once daily (varies). Purpose: simpler once-daily regimen for some patients. Mechanism: longer half-life covers the day; care to avoid over-replacement. Side effects: similar to other steroids if overdosed (glucose, weight, mood). Oxford Academic
Prednisone. Class: glucocorticoid prodrug. Dose: individualized—often comparable to prednisolone; converted in liver. Purpose/mechanism: same as above; choose based on availability/tolerability. Side effects: steroid-class effects with over-replacement. Oxford Academic
Cortisone acetate. Class: glucocorticoid. Dose: individualized (requires hepatic activation). Purpose: alternative to hydrocortisone where preferred. Mechanism/side effects: as for glucocorticoids; monitoring needed. Oxford Academic
Modified-release hydrocortisone (where available). Class: timed-release glucocorticoid. Dose: product-specific once-daily. Purpose: mimic the normal morning peak and daytime fall. Mechanism: controlled release profile to improve fatigue in some patients. Side effects: steroid-class, avoid over-replacement. Oxford Academic
Emergency hydrocortisone (hydrocortisone sodium succinate IM/IV). Class: parenteral glucocorticoid. Dose: 100 mg IM/IV immediately for suspected crisis, then continuous IV 200 mg/24 h or 50 mg IV/IM q6h; switch to oral as able. Purpose: life-saving cortisol in crisis or severe illness. Mechanism: rapid systemic steroid action. Side effects: minimal concern acutely; treat first, then titrate. endocrinology.org
DHEA (selected cases, especially some women). Class: adrenal androgen supplement. Dose: often 25–50 mg daily (specialist decision). Purpose: may improve low libido or mood in some; not routine for all. Mechanism: replaces reduced adrenal androgens. Side effects: acne, hair growth; benefits are mixed—specialist-guided. Oxford Academic
IV isotonic saline (0.9% NaCl) in crisis (supportive but essential). Class: fluid therapy. Dose: rapid bolus per emergency protocols. Purpose: restore blood pressure/volume. Mechanism: sodium/water expansion counters mineralocorticoid deficiency. Side effects: fluid overload if heart/renal disease—monitored in hospital. NCBI
Dextrose (IV glucose) in crisis with hypoglycemia. Class: carbohydrate infusion. Purpose/mechanism: corrects low blood sugar that occurs with severe cortisol lack. Side effects: vein irritation; monitor glucose. NCBI
Antiemetics during sick days (e.g., ondansetron if prescribed). Class: 5-HT3 antagonist. Purpose: control vomiting so oral steroids stay down; if not, give IM hydrocortisone. Side effects: constipation, headache; use by clinician advice. endocrinology.org
Electrolyte correction (e.g., careful potassium management if severe hyperkalemia). Class: hospital meds (calcium gluconate, insulin/glucose) per protocols. Purpose: stabilize the heart while steroids and fluids fix the cause. Side effects: monitored closely in ED/ICU. NCBI
Stress-dose steroids for procedures. Class: peri-operative hydrocortisone. Dose: 100 mg IV/IM at induction, then infusion 200 mg/24 h or 50 mg q6h; taper over 1–2 weeks as you recover. Purpose: prevent peri-operative crisis. Mechanism: covers anesthesia and surgical stress. Side effects: short-term steroid effects minimal compared to crisis risk. endocrinology.org
Antibiotics when infection is confirmed (not routine). Class: pathogen-specific. Purpose: treat triggers of crisis while steroids are increased. Mechanism: remove the stressor; dosing per infection guidelines. NCBI
Proton-pump inhibitor (when clinically indicated). Class: acid suppression. Purpose: protect stomach if higher steroid doses cause irritation during acute illness. Mechanism: reduces acid; only when needed. NCBI
Oral rehydration solution (ORS). Class: balanced electrolytes/glucose. Purpose: maintain hydration during mild illness alongside increased steroids. Mechanism: enhances sodium-glucose cotransport water uptake. Endocrine
Adjusting fludrocortisone seasonally (specialist-guided). Class: mineralocorticoid titration. Purpose: higher needs in heat/heavy sweating. Mechanism: compensate for sodium loss; based on BP, renin, and symptoms. Side effects: edema/hypertension if too high. Endocrine
Switching glucocorticoid type/formulation if symptoms persist. Class: individualized steroid plan. Purpose: improve daily energy and sleep. Mechanism: match circadian profile better for you. Side effects: same steroid precautions. Oxford Academic
Contraception and pregnancy planning with your team. Class: coordinated medication plan. Purpose: adjust doses and plan stress cover for labor/cesarean. Mechanism: pregnancy changes cortisol needs. Oxford Academic
Avoid long-term dexamethasone for routine replacement (generally). Class: long-acting glucocorticoid. Purpose: reduce risk of chronic over-replacement. Mechanism: very potent/long half-life—harder to mimic normal rhythm. Side effects: higher risk of metabolic effects if mis-dosed. Oxford Academic

Dietary molecular supplements

There is no supplement that replaces steroids. Some supports may help general health or correct deficiencies common in autoimmune conditions.

Sodium (salt) / electrolyte drinks during heat/exertion. Purpose: maintain volume; Mechanism: replaces sodium/water you would retain with aldosterone. Dose: individualized; sometimes salt tablets under supervision. Endocrine
Vitamin D (if low). Purpose: bone health with chronic steroid use; Mechanism: supports calcium absorption. Dose: per blood level and national guidance. Oxford Academic
Calcium (if dietary intake is low). Purpose: bones/teeth; Mechanism: maintains bone mineralization; use only if needed to avoid kidney stones. Dose: diet first, then supplements if advised. Oxford Academic
Vitamin B12 (if deficient or pernicious anemia is present). Purpose: correct anemia/nerve issues. Mechanism: replaces autoimmune-related deficiency sometimes seen with other autoimmune diseases. Dose: as prescribed after testing. NCBI
Iron (only if iron-deficiency anemia coexists). Purpose: restore hemoglobin. Mechanism: supplies iron for red blood cells. Dose: lab-guided; avoid if not deficient. NCBI
Folic acid (if low or in pregnancy planning). Purpose: red cell and fetal neural tube health. Mechanism: cofactor in DNA synthesis. Dose: per national guidance. Oxford Academic
Iodine/selenium: not for Addison’s itself; only if thyroid disease and deficiency exist. Purpose/mechanism: thyroid hormone synthesis; dose strictly per clinician. NCBI
Oral glucose/complex carbs during illness. Purpose: prevent hypoglycemia with anorexia. Mechanism: supports blood sugar alongside stress-dose steroids. Dose: small frequent intake. NCBI
Probiotics (optional, symptom-guided). Purpose: support gut during frequent antibiotic courses for intercurrent infections. Mechanism: microbiome balance; evidence general, not Addison-specific. Dose: as advised. NCBI
Multivitamin (if diet is limited). Purpose: general adequacy. Mechanism: fills minor gaps; not a treatment for Addison’s. Dose: standard daily. Oxford Academic

Immunity-booster / regenerative / stem-cell” drugs

There are no approved immune-boosting, regenerative, or stem-cell drugs that cure autoimmune Addison’s today. Research is exploring adrenal organoids and stem-cell–derived steroid-producing cells, and scientists continue to study the immune attack (especially 21-hydroxylase antibodies and T-cell responses), but these remain experimental and not available as clinical therapy yet. PMC+2Nature+2

Adrenal organoids (experimental). 3-D lab “mini-adrenals” created from stem cells aim to model steroid production and one day explore transplantation; not in clinical use. Dose: none—research only. Mechanism: replace or repair cortex function in theory. PMC+1
iPSC-derived adrenal cells (experimental). Scientists can nudge pluripotent cells toward adrenal-like cells in dishes; clinical translation will require safety/engraftment breakthroughs. PMC+1
Adrenal stem-cell niche targeting (preclinical). Reviews discuss signals that maintain adrenal progenitors; future drugs may aim to stimulate safe regeneration—no approved agents. PubMed
Immune-modulating strategies to halt early autoimmunity (theoretical). Because 21-hydroxylase antibodies mark disease, targeted immunotherapy has been speculated, but no validated regimen prevents progression or reverses Addison’s. PMC
General “immune boosters” (not recommended). Over-the-counter “boosters” don’t treat Addison’s and can interact with medicines—avoid claims of cures. Oxford Academic
Clinical trials watch. Ask your endocrinologist about trials in adrenal regeneration; as of now, standard of care remains glucocorticoid/mineralocorticoid replacement. Oxford Academic

Surgeries

There is no curative surgery for autoimmune Addison’s. Care is medical: daily steroid pills, stress-dosing, and emergency injections. Procedures you might encounter are supportive during emergencies rather than treatments for the disease itself. Oxford Academic+1

IV cannulation in crisis. Procedure to give fluids and hydrocortisone quickly; done because low blood volume and cortisol can cause shock. NCBI
Intraosseous access (if IV is difficult). Fast access for life-saving steroids/fluids in severe shock. NCBI
Central venous line (selected ICU cases). For ongoing infusions and monitoring during severe crises. NCBI
Peri-operative stress-dose protocol (anesthesia plan rather than surgery) to prevent crisis during other necessary surgeries. endocrinology.org
No adrenal transplant/adrenalectomy for Addison’s. Transplant is not standard; adrenalectomy treats other conditions (e.g., Cushing’s), not autoimmune Addison’s. Oxford Academic

Prevention

When to see a doctor now

Seek urgent care today if you have vomiting with inability to keep steroids down, severe weakness, fainting or very low blood pressure, confusion, very darkening skin suddenly with worsening dizziness, high fever (>39 °C), or symptoms of adrenal crisis (severe vomiting/diarrhea, abdominal pain, shock). Give your emergency hydrocortisone if trained, then go to emergency services immediately. NCBI+1

What to eat and what to avoid

Eat regular meals with complex carbs, protein, and fluids; don’t fast when ill. NCBI
Use salt liberally if your doctor advises (especially with fludrocortisone needs, heat, or exercise). Endocrine
Hydrate more during illness, heat, or strenuous activity. endocrinology.org
Favor potassium-rich foods in moderation only if your potassium is normal; if you run high K⁺, ask your clinician first. Endocrine
Adequate calcium and vitamin D through diet (and supplements only if advised) to support bones on long-term steroids. Oxford Academic
Limit alcohol during sick-day dosing; it worsens dehydration and nausea. endocrinology.org
Avoid “adrenal boosters” or steroid-like supplements marketed online; they don’t treat Addison’s and may interact with meds. Oxford Academic
During vomiting/diarrhea: switch early to ORS, then IM hydrocortisone if you can’t keep pills down and seek care. endocrinology.org
Hot climate days: add salty broths/soups and electrolyte drinks. Endocrine
Celiac symptoms or thyroid issues: ask about specific diets only if those diagnoses are confirmed. NCBI
