Addison Disease

What Is Addison’s Disease?

Addison’s disease is a rare, lifelong condition in which the adrenal glands — two small glands that sit above the kidneys — stop producing enough cortisol and, in most cases, enough aldosterone. It is the classic form of primary adrenal insufficiency, meaning the problem lies in the adrenal glands themselves rather than in the pituitary gland that controls them. Treatment replaces the missing hormones with daily medication and prepares you for the situations in which your body would normally produce far more cortisol than usual.

Being told you may have Addison’s disease can be unsettling, particularly when symptoms have been developing slowly and the cause has not been clear. Many people spend months feeling unusually tired, dizzy, weak or unable to recover from everyday stress before adrenal insufficiency is recognised. Others first learn about the condition during an emergency called an adrenal crisis, when cortisol levels fall too low for the body to maintain blood pressure, blood sugar and a normal stress response.

Two things are worth holding onto from the start. First, Addison’s disease is lifelong: the damaged adrenal tissue does not recover, and replacement therapy continues for life. Second, it is highly treatable when it is diagnosed accurately and managed carefully. Treatment is not a single procedure. It is a structured medical programme that replaces the hormones your adrenal glands can no longer produce, prevents crisis, and supports a normal daily routine — work, travel, exercise, pregnancy planning and everything in between.

A note on the name. You will see the condition written as Addison disease in American medical literature, as Addison’s disease in British usage, and often as addisons disease without the apostrophe in everyday searches. All three refer to the same diagnosis, named after the physician Thomas Addison, who first described it in the nineteenth century.

What causes Addison’s disease?

In many countries, the most common cause of Addison’s disease is autoimmune adrenalitis — the immune system mistakenly attacks the outer layer of the adrenal glands, gradually destroying the tissue that makes cortisol and aldosterone. Because the destruction is usually slow, symptoms often creep up over months or years before they are recognised.

Other causes matter too, and identifying them shapes the rest of your care:

• Infection, including tuberculosis, which remains an important cause of adrenal damage worldwide. When infection is suspected, evaluation may involve the infectious diseases department alongside endocrinology.
• Adrenal bleeding or thrombosis, which can damage both glands, sometimes during severe illness or with certain blood-clotting problems.
• Infiltrative diseases that replace normal adrenal tissue.
• Cancer spread to both adrenal glands, in selected patients with a relevant history.
• Surgical removal of both adrenal glands, after which hormone replacement is always required.
• Genetic conditions affecting adrenal development or hormone production, more often recognised in childhood.
• Certain medications that interfere with cortisol synthesis or accelerate its breakdown.

The cause is not always obvious at diagnosis. Part of a thorough evaluation is working out why the adrenal glands failed, because the answer affects what else should be screened for and how your long-term follow-up is planned.

What does low cortisol do to the body?

Low cortisol affects nearly every system, which is why the symptoms of Addison’s disease can seem so scattered. Cortisol helps regulate blood pressure, keeps blood sugar stable between meals, moderates the immune system, supports metabolism and — critically — rises sharply when the body is under physical stress from infection, injury or surgery. When cortisol is chronically low, the body loses its buffer against ordinary stresses. A minor stomach bug that a healthy person shrugs off can push someone with untreated Addison’s disease towards collapse.

Aldosterone, the second hormone usually affected, tells the kidneys to hold onto sodium and excrete potassium. When aldosterone is deficient, the body loses salt and water, blood pressure drops, potassium can rise, and dizziness on standing and salt craving become prominent. This is why treatment for Addison’s disease usually involves two hormones, not one.

Addison’s Disease Symptoms

What are the symptoms of Addison’s disease?

The most common Addison’s disease symptoms are persistent fatigue, muscle weakness, weight loss, poor appetite, nausea, abdominal discomfort, salt craving, dizziness when standing, low blood pressure and darkening of the skin. Mood changes, irritability and a reduced tolerance for stress or illness are also frequent. Because each of these can have other explanations, the condition is often mistaken at first for stress, depression, chronic fatigue, a gastrointestinal disorder or simple low blood pressure.

Some features are more distinctive and worth understanding:

• Skin darkening (hyperpigmentation). In primary adrenal insufficiency, the pituitary gland releases large amounts of ACTH in an attempt to stimulate the failing adrenal glands. High ACTH levels darken the skin, most visibly in creases of the palms, over knuckles and elbows, on scars, and inside the mouth. This sign points towards Addison’s disease specifically, because it does not occur when the problem lies in the pituitary.
• Salt craving. A strong, persistent desire for salty food reflects the salt loss caused by aldosterone deficiency.
• Dizziness on standing. Low blood volume and low blood pressure make the transition from sitting to standing feel unsteady, sometimes with brief visual dimming or faintness.
• Disproportionate illness. Minor infections hit harder and last longer than expected, because the normal cortisol surge that helps the body cope is missing.

Women may also notice reduced body hair or menstrual changes, because the adrenal glands contribute androgens that decline along with cortisol. In children, poor growth and delayed development can be part of the picture, which is one reason paediatric evaluation follows its own pathway.

What happens during an adrenal crisis?

An adrenal crisis is the sudden, severe expression of low cortisol: profound weakness, confusion, fainting, vomiting, diarrhoea, dehydration, very low blood pressure, low blood sugar and, if untreated, shock. It typically occurs when the body faces a stress — infection, injury, surgery, or persistent vomiting that prevents tablets from being absorbed — without a matching rise in cortisol. An adrenal crisis is a medical emergency. In hospital it is treated with intravenous hydrocortisone or an equivalent steroid, intravenous saline, glucose when needed, correction of electrolyte disturbances and treatment of whatever triggered the episode. Much of long-term Addison’s disease care is designed around making sure a crisis never gets that far.

Addison’s Disease and Other Forms of Adrenal Insufficiency

Adrenal insufficiency is the umbrella term for any condition in which the body does not have enough cortisol, and Addison’s disease is its primary form — the adrenal glands themselves have failed. Secondary adrenal insufficiency arises from pituitary disease, when the gland that produces ACTH cannot signal the adrenals properly. Tertiary adrenal insufficiency usually follows long-term steroid treatment for another condition, which suppresses the body’s own hormone axis. You can read more about the broader condition on our adrenal insufficiency page.

The distinction is not academic. In primary adrenal insufficiency, aldosterone is usually deficient as well, so mineralocorticoid replacement is typically needed; in most secondary forms it is not, because aldosterone production is controlled by a separate system that does not depend on the pituitary. The diagnostic pathway also differs: in Addison’s disease, ACTH is high because the pituitary is straining to stimulate unresponsive glands, whereas in secondary forms ACTH is low or inappropriately normal. Getting this classification right early prevents years of treatment aimed at the wrong problem.

Who Needs Evaluation and Treatment

You may need evaluation for Addison’s disease if you have symptoms of low cortisol, abnormal blood chemistry — particularly low sodium with high potassium — or an episode suggesting adrenal crisis. Because the condition develops gradually and its early symptoms resemble more common problems, diagnosis is sometimes delayed. A pattern worth noticing is the combination: fatigue plus weight loss plus dizziness plus salt craving plus darkening skin is far more suggestive than any single complaint alone.

Evaluation is also relevant for people who already carry the diagnosis. Reassessment can be worthwhile if you continue to feel unwell despite treatment, have frequent dizziness or salt craving, have needed repeated emergency visits, use unusually high or low steroid doses without a clear rationale, are planning pregnancy, are preparing for surgery, or travel extensively and want a more robust crisis-prevention strategy. Addison’s disease is managed well when the plan is periodically re-examined, not simply renewed.

A word about a question that appears constantly in searches: Addison’s disease also occurs in dogs, and much of what people read online about the condition comes from veterinary sources. The underlying biology is similar, but the testing, medications and dosing described for animals do not translate to human care. This page describes the condition and its treatment in people.

How to Test for Addison’s Disease

Testing for Addison’s disease rests on hormone measurement, interpreted alongside your history and examination — no single number makes the diagnosis on its own. The usual starting panel includes morning cortisol, ACTH, sodium, potassium, glucose and kidney function, often with plasma renin, aldosterone and adrenal autoantibodies. In primary adrenal insufficiency, cortisol is low while ACTH is high; sodium may be low, potassium high, and renin elevated when aldosterone activity is insufficient.

Timing and context matter more than many people expect. Cortisol follows a daily rhythm — highest in the early morning, falling through the day — and is influenced by stress, sleep, medications and changes in the proteins that carry it in the blood. Oral, injected, inhaled and even some topical steroids can suppress the hormone axis and distort results. Good testing means reliable assays, careful sample timing and experienced interpretation, because the goal is not to find a low number but to understand what it means for you.

How is the ACTH stimulation test performed?

The ACTH stimulation test checks whether your adrenal glands can respond to a direct signal: a synthetic form of ACTH is administered, and cortisol is measured at timed intervals afterwards. Healthy adrenal glands respond with a clear rise in cortisol; in Addison’s disease, the response is poor because the tissue that should respond has been damaged. The test itself is usually completed within a few hours as an outpatient procedure, although full interpretation requires correlation with your other laboratory values and clinical findings. It is often the confirming step when baseline results are suggestive but not conclusive.

Finding the cause

Once adrenal insufficiency is confirmed, the next question is why. Blood tests for adrenal antibodies support a diagnosis of autoimmune Addison’s disease. Depending on your history, screening may extend to thyroid function, blood glucose, coeliac serology, vitamin B12 and other autoimmune markers, because autoimmune adrenal disease often keeps company with other autoimmune conditions. Imaging with CT or MRI is reserved for patients in whom the cause is unclear, infection or bleeding is suspected, there is a cancer history, or the glands need structural assessment — it can show adrenal size, calcification, haemorrhage or masses. Imaging never replaces hormonal testing; it complements it in selected cases.

How Addison’s Disease Treatment Works

Treatment for Addison’s disease is a step-by-step medical pathway rather than an operation. It replaces what is missing, prepares you for what might go wrong, and adjusts over time as your life and health change. A complete plan usually includes:

• Daily cortisol replacement with a prescribed glucocorticoid schedule that aims to resemble the body’s natural cortisol rhythm as closely as possible.
• Aldosterone replacement when needed, to support blood pressure, salt balance, hydration and potassium control.
• Education on sick-day rules, so you know the circumstances in which steroid doses are increased — fever, vomiting, infection, injury, dental procedures, surgery — under a plan agreed in advance with your treating doctor.
• Emergency preparation, including written instructions, medical identification and access to injectable emergency steroid medication where appropriate.
• Monitoring and dose adjustment through endocrinology follow-up, clinical review and targeted laboratory tests.
• Evaluation of the underlying cause and screening for associated conditions.

Unlike treatments that end after a procedure, this care is ongoing. The plans that work best are the ones patients can actually live with: a frequent traveller, a shift worker, a competitive athlete and a person with several autoimmune conditions will each need a different strategy. Medical soundness and daily practicality both matter.

Step 1: Clinical assessment and medical history

The first stage is a detailed review of your symptoms, prior test results, medications, past infections, autoimmune history, family history, weight changes, blood pressure patterns and any previous episodes of collapse, dehydration or unexplained hospitalisation. Current steroid exposure is reviewed with particular care, because steroids in any form can affect the hormone axis and complicate the interpretation of tests. The physician also judges whether the situation is stable or urgent: if there are signs of adrenal crisis, treatment is not delayed for complete testing — emergency therapy is started immediately, with diagnostic samples drawn beforehand only if that can be done safely.

Step 2: Confirming the diagnosis

For stable patients, the biochemical work described above — baseline hormones, electrolytes, renin and aldosterone, followed where needed by the ACTH stimulation test — confirms whether cortisol production is genuinely deficient and whether the problem is primary. This step also formally distinguishes Addison’s disease from secondary and tertiary adrenal insufficiency, a distinction that determines whether aldosterone replacement will be part of your regimen and what further investigations are warranted.

Step 3: Starting glucocorticoid replacement

Daily glucocorticoid replacement stands in for the cortisol your adrenal glands no longer make. The specific medication and schedule are individualised; many patients take divided doses through the day, larger in the morning and smaller later, to echo the natural rhythm. The aim is to relieve the symptoms of deficiency without tipping into chronic overtreatment, which carries its own costs over years — weight gain, sleep disturbance, bone loss, raised blood pressure, raised blood sugar and skin changes. One point is drilled into every patient from the first appointment: in Addison’s disease, replacement steroids are never stopped abruptly, because missed doses can become dangerous, especially during illness. Any change to the regimen belongs with your treating endocrinologist.

Step 4: Mineralocorticoid replacement when aldosterone is low

If aldosterone is deficient, a mineralocorticoid is prescribed to maintain blood pressure and electrolyte balance. Its dose is guided by how you feel — dizziness, salt craving, swelling — together with blood pressure readings, sodium and potassium levels and renin measurements. Some patients also receive advice on salt and fluid intake, particularly relevant in hot climates, during heavy exercise or during gastrointestinal illness, when salt and water losses climb.

Step 5: Emergency treatment of adrenal crisis

When a crisis occurs, hospital care typically includes intravenous hydrocortisone or an equivalent, intravenous saline, glucose where needed, correction of electrolyte disturbances and treatment of the trigger. Blood pressure, heart rate, glucose, kidney function and electrolytes are monitored closely. Patients usually improve with appropriate emergency treatment, but before discharge the trigger must be addressed and the long-term plan reviewed. A crisis is also a teaching moment: what warning signs appeared, whether stress dosing started early enough, and whether injectable medication and emergency information were actually to hand when they were needed.

Step 6: Education for daily life, travel and procedures

Education is not an add-on; it is treatment. You learn the sick-day rules your endocrinologist sets for you, what happens if vomiting prevents tablets from being absorbed, and the circumstances in which an emergency injection is used. Carrying medical identification and written instructions is standard advice, and becomes more important the further you are from your usual medical team. For planned procedures, the endocrinologist coordinates with surgeons, anaesthetists or dentists to establish perioperative steroid coverage, because operations and significant dental work are precisely the situations in which a healthy body would produce a large cortisol surge.

Step 7: Follow-up and long-term monitoring

Follow-up visits review your symptoms, blood pressure sitting and standing, weight, energy, sleep, salt craving, medication timing, adherence and any emergency events since the last visit. Laboratory monitoring may cover electrolytes, kidney function, renin, glucose, lipids, bone health and associated endocrine conditions. Visit frequency depends on how stable you are, how recently doses changed, pregnancy planning, comorbidities and whether the diagnosis is new. Most care is outpatient. Diagnosis may take one visit or several depending on prior testing; symptomatic improvement often begins within days of appropriate replacement, but fine-tuning typically takes weeks to months because dose timing, lifestyle and associated conditions all need to be refined carefully.

Conditions and Indications Addressed by Addison’s Disease Care

The central indication is chronic underproduction of cortisol by the adrenal glands, with or without aldosterone deficiency. Around that core, care extends to identifying the underlying cause — autoimmune adrenalitis, infection, adrenal bleeding or thrombosis, prior bilateral adrenal surgery, or rarer inherited and infiltrative conditions — and to screening for the company Addison’s disease often keeps.

In some patients, Addison’s disease occurs within an autoimmune polyglandular syndrome, alongside conditions such as autoimmune thyroid disease (including Graves disease), type 1 diabetes, coeliac disease, pernicious anaemia or ovarian insufficiency. Recognising these associations improves long-term management: when new symptoms appear years after diagnosis, a team that knows the pattern is less likely to overlook a second treatable condition hiding behind the first.

Crisis prevention is itself an indication for structured care. This includes patients who have already had a crisis, those prone to vomiting illnesses that interrupt oral medication, patients facing surgery or major dental procedures, and people exposed to serious infections, trauma or heavy physical stress. In all of these situations the body would normally raise cortisol production sharply; because the adrenal glands cannot do so in Addison’s disease, stress-dose planning stands in for that missing reflex.

Why Acting Early Matters

Untreated Addison’s disease can progress from vague symptoms to life-threatening adrenal crisis. Because cortisol underpins blood pressure, blood sugar and circulation under stress, the body becomes vulnerable during infections, dehydration, surgery, trauma or severe vomiting. Delayed diagnosis tends to mean repeated emergency visits, worsening weakness and weight loss, electrolyte abnormalities and complications that better timing would have avoided.

Early diagnosis also spares patients the frustration of mislabelling. People with Addison’s disease are sometimes treated for fatigue, anxiety, gastrointestinal complaints or low blood pressure for long stretches before the hormone deficiency is recognised. Once the diagnosis is clear, treatment becomes targeted and the endless cycle of partial explanations stops.

Timing matters after diagnosis, too. Both undertreatment and overtreatment carry costs: too little replacement leaves you exhausted, dizzy, nauseated and exposed to crisis; too much glucocorticoid over years affects bone density, metabolism, weight, sleep and cardiovascular risk. Careful endocrine follow-up is what keeps the regimen on the narrow path between the two.

Can Addison’s disease be cured?

No — Addison’s disease cannot currently be cured, because the destroyed adrenal tissue does not regrow. Personal accounts online claiming a cure through diet, supplements or lifestyle change do not reflect how the condition works; in confirmed primary adrenal insufficiency, stopping replacement therapy is dangerous, whatever else has changed. What treatment genuinely offers is different and substantial: reliable control of symptoms, protection against crisis, and a daily life that looks, for most practical purposes, like everyone else’s. That is worth stating plainly, because chasing a cure can distract from the planning that actually keeps people well.

Benefits of Addison’s Disease Treatment

When Addison’s disease is diagnosed accurately and managed consistently, treatment can substantially improve daily function and reduce the risk of serious complications.

Benefit	What It Means for You
Replacement of missing cortisol	Helps restore energy, appetite, blood pressure stability, stress tolerance and general physical resilience.
Improved salt and fluid balance	Mineralocorticoid treatment, when needed, can reduce dizziness, salt craving, dehydration risk and potassium abnormalities.
Lower risk of adrenal crisis	Education, stress-dose planning and emergency medication reduce the likelihood that illness or injury becomes dangerous.
More accurate diagnosis	Testing distinguishes primary adrenal insufficiency from pituitary-related or medication-related adrenal problems, guiding the right treatment.
Better preparation for travel and procedures	A written plan supports safer international travel, surgery, dental work, pregnancy planning and management during infections.
Long-term health monitoring	Regular follow-up helps avoid under-replacement and over-replacement while screening for associated endocrine or autoimmune conditions.

Recovery and Adjustment Timeline

Treatment often brings early improvement, but the timeline varies with how severe the deficiency was, whether a crisis occurred, and how quickly the medication plan is optimised.

Time Period	What You Can Expect
Day 1	In an adrenal crisis, emergency steroid and fluid treatment begins quickly in hospital. Stable patients may start or adjust oral hormone replacement after diagnostic review.
First week	Energy, nausea, dizziness and appetite may begin to improve. You learn medication timing, stress-dose rules and the warning signs that require urgent care.
First month	Doses are refined against symptoms, blood pressure, electrolytes and your daily routine. Any underlying cause or associated condition is investigated further.
First 3 to 6 months	Confidence grows in managing work, travel, exercise and illness. Follow-up focuses on stability, avoiding overtreatment and emergency preparedness.
Longer term	Lifelong endocrinology follow-up continues. Patients usually live active lives when replacement therapy is consistent and crisis-prevention plans are understood.

Living With Addison’s Disease

How does Addison’s disease affect daily life?

Day to day, well-treated Addison’s disease affects life less than most newly diagnosed patients fear. The visible routine is modest: tablets taken at set times, a small emergency kit, medical identification carried in a wallet or worn on the wrist. What changes more is the mental habit of planning ahead. You learn to think about medication when packing for a trip, to keep a supply that outlasts the journey, to note where hospitals are when travelling somewhere remote, and to treat fevers and stomach bugs as events with a protocol rather than nuisances to push through. Exercise, demanding jobs and long-haul travel are all compatible with the condition; they simply go better with preparation. Many patients also find it worthwhile to teach a partner, family member or close colleague what an adrenal crisis looks like and where the emergency injection is kept, so that help does not depend on the patient being well enough to organise it.

Some patients describe less predictable energy than before diagnosis, particularly in the first months while doses and timing are being refined. Persistent fatigue despite treatment is a reason for review rather than resignation — it can reflect dose timing, an associated condition such as thyroid disease or coeliac disease, sleep problems, or something unrelated to the adrenal glands at all. The point of follow-up is to keep asking that question rather than assuming the diagnosis explains everything.

What is the life expectancy of someone with Addison’s disease?

With consistent hormone replacement, sound education and access to emergency care, people with Addison’s disease can generally expect to live long, active lives. The serious danger in this condition is concentrated in one scenario: an adrenal crisis that is not treated in time, most often triggered by infection, injury or interrupted medication. That risk is exactly what the structured elements of care — sick-day rules, injectable steroid, medical identification, perioperative planning — exist to shrink. Long-term outlook also depends on avoiding chronic over-replacement and on managing any associated autoimmune or endocrine conditions, which is why the honest answer to this question is less about the diagnosis itself and more about the quality and consistency of the care around it.

Factors That Influence Outcomes

The general outlook for Addison’s disease is favourable when the condition is recognised, treated consistently and monitored by experienced clinicians. Most patients can work, travel, exercise and maintain a full life, but the quality and safety of long-term management depend on several factors.

Accuracy of diagnosis comes first. Addison’s disease should be confirmed with appropriate hormonal testing and interpreted in clinical context. Treating without clarity risks unnecessary medication; missing the diagnosis exposes you to crisis. Distinguishing primary from secondary and tertiary adrenal insufficiency also shapes treatment decisions, especially whether mineralocorticoid replacement is needed.

Appropriate dosing is equally important. The best dose is not the highest dose that makes you feel more energetic; it is the dose that replaces what is missing without creating long-term steroid excess. Physicians weigh symptoms, blood pressure, weight, sleep quality, glucose, bone health, lifestyle and laboratory findings — and dose timing can matter as much as the total daily amount.

Patient education strongly influences safety. Patients who understand their sick-day rules, carry identification, keep written emergency instructions and know when urgent care is needed are far better prepared for infections, vomiting, trauma or travel disruption. Family members or close contacts who can recognise crisis signs add a second layer of protection when the patient is too unwell to act alone.

Management of associated conditions affects how well you feel. Autoimmune thyroid disease, type 1 diabetes, coeliac disease, anaemia, vitamin deficiencies and other endocrine disorders can all sustain fatigue or weight change even when adrenal replacement is correct. A broader endocrine assessment often explains why a patient does not feel well despite technically adequate treatment.

Life circumstances matter too. Hot climates, intense exercise, irregular sleep, demanding travel schedules, pregnancy, planned surgery and recurrent infections each call for more detailed planning. Anyone travelling internationally with Addison’s disease is well served by an ample medication supply, written medical documents and instructions in a format that can be shared with unfamiliar physicians if emergency care is ever needed abroad.

Regular follow-up holds the rest together. This condition is not managed well by prescription renewal alone. Symptoms, blood pressure, electrolytes, renin, comorbidities, bone and metabolic risk and any emergency events deserve periodic review. A good result is one in which you feel stable, understand your condition, and hold a clear plan for both ordinary days and stressful ones.

How Acibadem Organises Addison’s Disease Care

At Acibadem, Addison’s disease care is led by endocrinology and coordinated across the departments a given case requires — internal medicine, emergency medicine, radiology, infectious diseases, surgery and obstetrics among them. The condition rewards this kind of coordination because accurate sample handling, timely emergency response, medication safety and communication between teams all bear directly on how well a patient does. Complex cases — adrenal insufficiency associated with pituitary disease, autoimmune syndromes, infection, malignancy or planned surgery — can be discussed through multidisciplinary consultation rather than handled by a single specialty in isolation.

Diagnostic resources include laboratory testing for hormone levels, electrolytes, autoimmune markers and related endocrine conditions, dynamic endocrine testing such as adrenal stimulation assessment where clinically appropriate, and CT or MRI when adrenal structure needs evaluation. These tools earn their keep only when integrated with careful clinical judgement, because Addison’s disease care depends on interpretation, not testing volume.

Treatment plans are shaped around the individual: diagnosis, current medications, age, weight, symptoms, occupation, travel patterns and other medical conditions. For a newly diagnosed patient, the priority is usually education and stabilisation. For an experienced patient reviewing their regimen, the focus may be dose timing, persistent fatigue, repeated dizziness or screening for associated autoimmune disease. For a patient preparing for surgery, it is perioperative steroid coverage agreed between the endocrine, surgical and anaesthesia teams. In every case, patients leave with written documentation of the plan — a practical detail that matters more in this condition than in most, because the plan has to keep working wherever the patient happens to be.

A Care Plan Built for Stability

Addison’s disease requires lifelong attention, but it does not have to define a life. With accurate diagnosis, appropriate hormone replacement, honest education and regular endocrinology follow-up, most patients regain stability and return to their normal activities. The decisive step is having a clear plan and understanding it: what is taken each day and why, what changes during illness, how travel and procedures are prepared for, and when urgent care is the right call. A patient who leaves the clinic with that understanding — not just a prescription — is the real measure of good Addison’s disease care.

Frequently Asked Questions

What is Addison's disease and what causes it?

Addison's disease is primary adrenal insufficiency, a rare, lifelong condition in which the adrenal glands stop producing enough cortisol and, in most cases, aldosterone. In many countries the most common cause is autoimmune adrenalitis, where the immune system gradually damages adrenal tissue. Other causes can include infection such as tuberculosis, adrenal bleeding, surgical removal of both glands, genetic conditions and certain medications. Your doctor will usually try to identify the cause, as it shapes follow-up.

What are the most common symptoms of Addison's disease?

Common symptoms may include persistent fatigue, muscle weakness, weight loss, poor appetite, nausea, abdominal discomfort, salt craving, dizziness when standing, low blood pressure and darkening of the skin. Mood changes and a reduced tolerance for stress or illness are also frequent. Because these features can have other explanations, the condition is often mistaken at first for stress, depression, chronic fatigue or a gastrointestinal disorder, and diagnosis can be delayed.

How is Addison's disease diagnosed and tested?

Diagnosis rests on hormone measurement interpreted alongside your history and examination; no single number confirms it on its own. The usual starting panel includes morning cortisol, ACTH, sodium, potassium, glucose and kidney function, often with renin, aldosterone and adrenal autoantibodies. An ACTH stimulation test is often the confirming step when baseline results are suggestive but not conclusive. Imaging with CT or MRI is reserved for selected cases where the cause is unclear.

How is Addison's disease treated in the long term?

Treatment is lifelong hormone replacement rather than an operation. It usually involves daily glucocorticoid tablets, often in divided doses to echo the body's natural cortisol rhythm, with a mineralocorticoid added when aldosterone is also deficient. Care also includes education on sick-day rules, emergency preparation with injectable steroid where appropriate, and regular endocrinology follow-up to adjust doses. Replacement steroids should never be stopped abruptly; any change belongs with your treating endocrinologist.

When should I seek urgent medical advice with Addison's disease?

Seek emergency care immediately if you develop signs of adrenal crisis: profound weakness, confusion, fainting, vomiting, diarrhoea, dehydration or very low blood pressure. A crisis can be triggered by infection, injury, surgery or persistent vomiting that prevents tablets from being absorbed. If you feel unwell, or your symptoms are severe or getting worse, get medical care where you are now rather than waiting. Persistent fatigue despite treatment is also a reason to ask your doctor for review.

Can Addison's disease be cured or does treatment last for life?

Addison's disease cannot currently be cured, because the damaged adrenal tissue does not regrow, so replacement therapy continues for life. Claims of a cure through diet, supplements or lifestyle change do not reflect how the condition works, and stopping replacement in confirmed primary adrenal insufficiency is dangerous. With consistent treatment, education and regular follow-up, however, many people return to normal work, travel and exercise and can generally expect to live long, active lives.
