Autoimmune Polyglandular Syndrome
What is Autoimmune Polyglandular Syndrome?
Autoimmune polyglandular syndrome is a rare condition where your immune system attacks multiple hormone-producing glands at once. Your body mistakenly identifies healthy gland tissue as foreign and launches an attack against it. This leads to dysfunction in two or more endocrine glands, which are organs that make hormones to regulate your body.
There are different types of this syndrome. Type 1 usually appears in childhood and affects the parathyroid glands, adrenal glands, and sometimes the thyroid. Type 2 is more common and typically shows up in adults. It often involves the adrenal glands, thyroid gland, and sometimes the pancreas. Type 3 affects the thyroid and other glands but spares the adrenal glands.
When these glands stop working properly, your body loses the ability to make critical hormones. These hormones control everything from your metabolism and blood sugar to your calcium levels and stress response. Understanding which glands are affected helps guide your treatment and testing plan.
Symptoms
- Extreme fatigue that does not improve with rest
- Unexplained weight loss or difficulty maintaining weight
- Darkening of the skin, especially in skin folds and scars
- Dizziness or fainting when standing up quickly
- Salt cravings or increased thirst
- Low blood sugar episodes with shakiness or confusion
- Muscle weakness or cramping
- Changes in menstrual periods or fertility issues
- Hair loss or brittle nails
- Digestive problems including nausea or diarrhea
Some people have mild symptoms for months or years before diagnosis. Others may develop sudden adrenal crisis, which is a medical emergency. Early symptoms can be vague and easy to dismiss as stress or aging.

Causes and risk factors
Autoimmune polyglandular syndrome happens when your immune system makes antibodies that attack your own glands. Genetics play a major role in who develops this condition. Type 1 is caused by mutations in a gene called AIRE, which helps your immune system learn what is self and what is foreign. Type 2 and Type 3 run in families but involve multiple genes related to immune function.
Having one autoimmune condition increases your risk of developing others. People with type 1 diabetes, celiac disease, or vitiligo have higher rates of polyglandular syndrome. Women are affected more often than men, especially for Type 2. Environmental triggers like infections or stress may activate the condition in people who are genetically vulnerable. However, many cases appear without any clear trigger.
How it's diagnosed
Diagnosis starts with a detailed medical history and physical exam. Your doctor will look for signs of multiple gland problems, like skin changes, weight loss, or low blood pressure. Blood tests measure hormone levels from different glands to see which ones are not working properly. Testing for specific antibodies helps confirm the autoimmune nature of the condition.
Thyroglobulin antibodies can indicate an autoimmune attack on your thyroid gland. Rite Aid offers thyroglobulin antibody testing as an add-on to our flagship blood panel. Additional specialized tests may be needed to check adrenal function, parathyroid hormone levels, and other gland markers. Early detection through blood testing allows you to start treatment before severe damage occurs.
Treatment options
- Hormone replacement therapy to replace what your glands can no longer make
- Hydrocortisone or other corticosteroids for adrenal insufficiency
- Levothyroxine for thyroid hormone replacement when needed
- Insulin therapy if the pancreas is affected and diabetes develops
- Calcium and vitamin D supplements for parathyroid problems
- Regular monitoring of hormone levels with blood tests
- Eating a nutrient-dense diet with adequate protein and healthy fats
- Managing stress through rest, sleep, and relaxation practices
- Wearing a medical alert bracelet in case of adrenal crisis
- Working with an endocrinologist who specializes in hormone disorders

Frequently asked questions
Type 1 usually starts in childhood and is caused by a specific gene mutation. It often affects the parathyroid glands, adrenal glands, and skin. Type 2 appears in adults and involves the adrenal glands, thyroid, and sometimes the pancreas. Type 2 is more common and tends to run in families without a single gene cause.
There is no cure for this condition because the immune system damage is permanent. However, symptoms can be managed very effectively with hormone replacement therapy. Most people live full lives when their hormone levels are properly balanced with medication. Regular monitoring and adjustment of treatment keep the condition under control.
Most people need blood tests every 3 to 6 months after diagnosis to monitor hormone levels. Your doctor may test more frequently when adjusting medications or if new symptoms appear. Regular testing helps catch problems early before they become serious. Thyroid antibodies and hormone levels should be tracked over time.
Yes, genetics play a significant role in this condition. Type 1 follows a clear inheritance pattern from a single gene mutation. Type 2 and Type 3 involve multiple genes and are more complex. If you have this syndrome, your family members have a higher risk and may benefit from screening.
Adrenal crisis happens when your body needs more cortisol than your damaged adrenal glands can provide. Stress from illness, surgery, or injury can trigger it. You prevent crisis by taking your corticosteroid medication exactly as prescribed and increasing your dose during times of physical stress. Always wear a medical alert bracelet and carry emergency injectable cortisol.
Diet and lifestyle support your treatment but cannot replace hormone medication. Eating balanced meals with protein, healthy fats, and vegetables helps stabilize blood sugar and energy. Managing stress, getting adequate sleep, and staying hydrated all support your endocrine system. However, you will still need hormone replacement therapy to replace what your glands cannot make.
Untreated gland failure can lead to serious complications or death. Adrenal insufficiency causes dangerously low blood pressure and electrolyte imbalances. Thyroid problems lead to severe fatigue, heart issues, and mental health changes. Low calcium from parathyroid damage causes muscle spasms and seizures. Treatment is essential to prevent these life-threatening problems.
People with this syndrome have a higher risk of developing additional autoimmune diseases. Common ones include celiac disease, pernicious anemia, and vitiligo. Your doctor should monitor you for new symptoms and screen for other conditions periodically. Early detection of new autoimmune problems allows for prompt treatment and better outcomes.
Thyroglobulin antibodies indicate that your immune system is attacking thyroid tissue. Finding these antibodies confirms the autoimmune nature of thyroid damage. This test helps distinguish autoimmune thyroid disease from other causes of thyroid problems. It also helps predict whether your thyroid function will worsen over time.
Stress does not cause the syndrome but can worsen symptoms, especially if you have adrenal insufficiency. Your damaged adrenal glands cannot increase cortisol production during stress like healthy glands can. This makes physical stress from illness or injury particularly dangerous. You may need to temporarily increase your corticosteroid dose during stressful periods under medical guidance.
