What is Addison's Disease?

Addison's disease is a rare and chronic condition that affects the adrenal glands³. These glands sit on top of the kidneys and make important hormones like cortisol and aldosterone. When the glands are damaged, they can't make enough of these hormones³.For more on how to manage adrenal health, visit our guide to maintaining overall health.

Primary vs. Secondary Adrenal Insufficiency

There are two types of adrenal insufficiency: primary and secondary. Primary adrenal insufficiency, or Addison's disease, happens when the adrenal glands are damaged³. Secondary adrenal insufficiency occurs when the pituitary gland doesn't make enough hormone to help the adrenal glands work right⁴.

Both conditions lead to a lack of cortisol and aldosterone. But they have different causes.Understanding the distinction is essential for accurate diagnosis and effective treatment.⁴.Discover more about primary and secondary conditions here.

Addison's disease is rare, affecting about 1 in 10,000 people in the UK³. In the US, it's estimated to affect between 40 and 60 people per million⁴. It can happen at any age, but most often between 30-50³. Women are more likely to get it, by a ratio of two to three times more than men³.

Symptoms of Addison's Disease

Addison's disease is a rare and serious condition that can show many symptoms⁵. These symptoms often start slowly and can be missed at first⁵. Common signs include:

• Extreme fatigue and weakness
• Unintentional weight loss
• Darkening of the skin, known as hyperpigmentation
• Low blood pressure, or hypotension
• Salt cravings
• Nausea, vomiting, and digestive issues
• Muscle and joint pain
• Depression and mood changes

In severe cases, an acute adrenal crisis can happen. This leads to serious symptoms like severe weakness, confusion, and dehydration⁵. This crisis is life-threatening and needs quick medical help to avoid serious harm⁶.

Symptom	Description
Chronic Fatigue	Persistent and debilitating tiredness that is not relieved by rest.
Weight Loss	Unintentional and unexplained weight loss, often due to decreased appetite.
Hyperpigmentation	Darkening of the skin, particularly in areas exposed to the sun or areas of friction.
Low Blood Pressure	Abnormally low blood pressure, which can lead to dizziness and fainting.
Salt Craving	An intense desire for salty foods, often due to the body's inability to retain sodium.
Nausea and Vomiting	Digestive issues that can lead to dehydration and electrolyte imbalances.
Muscle Pain	Aches and pains in the muscles, often accompanied by fatigue.
Depression	Mood changes and feelings of sadness or hopelessness.

The symptoms of Addison's disease can be subtle and different for everyone⁵⁷. Early diagnosis and proper treatment are key to avoiding serious problems⁶.Learn more about health-related emergencies in our article here.

Causes and Risk Factors

Addison's disease often starts with an autoimmune attack on the adrenal glands⁸. This is the main reason for the disease in the UK⁹. When 90% of the adrenal cortex is lost, symptoms appear⁹.

Genetics can increase the risk of getting autoimmune diseases like Addison's⁹. Infections, like tuberculosis (TB), can also cause it, though it's rare in the UK⁹. Other causes include AIDS-related infections, cancer, and damage from treatments⁹.

People with type 1 diabetes or thyroid issues are more likely to get Addison's disease⁸. Long-term use of certain drugs and pituitary gland damage can lead to a similar but different condition⁸⁹.

Autoimmune Diseases and Genetic Factors

The main cause of Addison's disease is an autoimmune attack on the adrenal glands⁸. Genetics can make some people more likely to get autoimmune diseases, including Addison's⁹.

Those with type 1 diabetes or thyroid problems are more at risk of getting Addison's disease⁸. This shows how genetics and the immune system work together in this condition.

Diagnosis and Testing

Diagnosing Addison's disease requires several steps. Blood tests, an ACTH stimulation test, and imaging scans are used¹⁰. Blood tests show low sodium, high potassium, and anemia, common signs of the disease¹¹. The ACTH test checks how the body responds to a hormone injection, helping confirm the diagnosis¹².

Imaging tests, like a CT scan of the adrenal glands, look for underlying problems¹¹. A tuberculosis test might also be done, as this infection can cause Addison's disease¹¹.

More tests might be needed, like the insulin tolerance test or CRH stimulation test, to understand the cause¹². Antibody tests can find antibodies in autoimmune Addison's disease¹².

In an adrenal crisis, quick action is key. Treatment with steroid injections and fluids starts based on symptoms¹⁰. People with Addison's disease and certain licenses must tell the DVLA¹⁰.

Treatment and Management

The primary approach to treating Addison's disease involves hormone replacement therapy.This usually includes oral hydrocortisone for cortisol and fludrocortisone for aldosterone¹³. People with Addison's must take these medicines every day. They need to increase the dose when stressed, sick, or hurt to avoid a serious adrenal crisis¹³.

They also need to carry emergency meds, wear a medical alert bracelet, and watch their symptoms closely with their healthcare team.

Hydrocortisone is often used to replace cortisol¹⁴. Fludrocortisone is needed for those with aldosterone deficiency¹⁴. In an adrenal crisis, doctors give IV corticosteroids and saline right away¹⁴.

Before, during, and after surgery, patients may get IV corticosteroids and saline¹⁴.

When sick, especially with high fever, more corticosteroids are needed¹⁴. Severe injuries or serious illnesses might require even more¹⁴. Pregnant women with adrenal insufficiency might get corticosteroid shots early in pregnancy if they can't take pills¹⁴.

After giving birth, their doses will slowly go back to normal, usually about 10 days later¹⁴.

It's very important for those with Addison's to stick to their treatment plan. They should always carry emergency meds and work closely with their healthcare team. This helps prevent serious adrenal crises¹³.

Conclusion

Addison's disease is a rare, chronic condition that needs lifelong care¹⁵. But, with the right treatment, people with Addison's can live full lives. Knowing the causes, like autoimmune disorders and tuberculosis¹⁵, helps patients manage their condition better.

They can also recognize symptoms like chronic fatigue, weight loss, and hyperpigmentation¹⁵. This way, they can work with their doctors to avoid serious adrenal crises.

Following medication, managing stress, and regular doctor visits are key for a good quality of life¹⁵. Although Addison's disease is rare, affecting only 1 in 100,000 people¹⁵, it's important to be aware and manage it well. By staying informed and working with their doctors, those with Addison's can lead happy and fulfilling lives.

FAQ 

What Happens if Diagnosed with Addison's Disease?

If diagnosed with Addison's disease, also known as primary adrenal insufficiency, the body is unable to produce enough of the essential hormones cortisol and often aldosterone, which are critical for various bodily functions, including metabolism, immune response, and blood pressure regulation. This hormone deficiency can lead to several health issues, ranging from fatigue and weakness to low blood pressure and salt cravings. Patients will typically start on hormone replacement therapy, a lifelong treatment that aims to replace the missing hormones and help restore normal body functions. Without treatment, Addison’s disease can lead to severe complications like Addisonian crisis, which is a medical emergency that requires immediate intervention.

What Are Three Symptoms of Addison's Disease?

Three common symptoms of Addison’s disease are: Chronic fatigue and muscle weakness: Patients often feel unusually tired, even after rest, due to low cortisol levels. Low blood pressure: This can cause dizziness, especially when standing, because of the lack of aldosterone, which helps regulate sodium and potassium levels. Hyperpigmentation (darkening of the skin): Commonly found on the face, hands, or scars, this symptom arises due to elevated levels of ACTH (adrenocorticotropic hormone) attempting to stimulate the adrenal glands. Other symptoms may include weight loss, salt cravings, and gastrointestinal discomfort.

Is Addison's Disease Life-Threatening?

Yes, Addison’s disease can be life-threatening if left untreated. A condition known as Addisonian crisis, or acute adrenal crisis, can occur if the body’s cortisol levels drop suddenly. This crisis can lead to severe dehydration, dangerously low blood pressure, and shock. Addisonian crisis requires immediate medical attention and is often triggered by stress, illness, or injury. However, with regular hormone replacement therapy and careful monitoring, individuals with Addison’s disease can manage the condition and significantly reduce the risk of life-threatening episodes.

What Is the Life Expectancy of Addison's Disease?

With early diagnosis and effective treatment, the life expectancy of someone with Addison’s disease is typically normal. Modern advancements in hormone replacement therapy have improved outcomes for people with this condition. However, untreated Addison’s disease, or poor management, can increase the risk of life-threatening Addisonian crisis and other complications. Individuals with Addison’s are encouraged to maintain regular follow-up care and promptly address any unusual symptoms or stressors to help ensure a healthy and normal lifespan.

How to Confirm Addison's Disease?

Addison's disease is confirmed through a combination of laboratory tests and imaging. Key tests include: ACTH stimulation test: This test measures how well the adrenal glands respond to ACTH (a hormone that stimulates cortisol production). Low cortisol levels after ACTH injection can indicate Addison’s disease. Blood tests: These can check for low sodium, high potassium, and low cortisol levels. Elevated ACTH levels in the blood may also suggest adrenal insufficiency. Imaging tests: CT scans or MRI can help identify any damage to the adrenal glands. Together, these tests provide a clear picture of adrenal gland function and can confirm a diagnosis of Addison's disease.

What Organ is Damaged in Addison's Disease?

Addison’s disease primarily affects the adrenal glands, which are small glands located above each kidney. The adrenal cortex, the outer layer of the adrenal glands, becomes damaged and unable to produce sufficient cortisol and aldosterone. This damage is usually due to an autoimmune response, where the immune system mistakenly attacks the adrenal tissue. Other causes include infections, cancer, and certain genetic disorders. The resulting hormone deficiencies require lifelong management with hormone replacement therapy.
