Addison's Disease

Overview

Addison disease is when the adrenal glands don't make enough of two steroid hormones. The hormones are cortisol and aldosterone. Cortisol controls the body's metabolism, blocks inflammatory reactions, and affects the immune system. Aldosterone manages sodium and potassium levels. The adrenal glands sit on top of the kidneys. There is one gland on top of each kidney. Addison disease is fairly rare and may first appear at any age.

Causes

The most common cause of Addison disease is damage to the adrenal glands caused by an autoimmune disease. Other cases of Addison disease are caused by the damage to the glands by any of these:

• Cancer
• Infection
• An autoimmune problem
• A rare genetic disease

In rare cases, Addison disease is passed down in a family.

Other causes of low corticosteroids can include:

• Use of corticosteroid medicine. This includes prednisone. The medicines lower the amount of natural corticosteroids made by the adrenal glands.
• Use of some medicines to treat fungal infection. These medicines may stop corticosteroids being made in the adrenal glands.

Risk Factors

A child is at risk for Addison disease if he or she has any of these:

• An autoimmune disease
• Cancer
• Infection such as tuberculosis
• Family history of the disease
• History of using corticosteroid medicine
• History of using anti-fungal medicine

Symptoms

Mild symptoms may only occur when a child is under physical stress. Symptoms may include:

• Muscle weakness
• Fatigue
• Dizziness
• Fast pulse
• Dark skin, first seen on hands and face
• Black freckles
• Bluish-black color around the nipples, mouth, rectum, scrotum, or vagina
• Weight loss
• Dehydration
• Loss of appetite
• Intense salt craving
• Muscle aches
• Nausea
• Vomiting
• Diarrhea
• Intolerance to cold

The symptoms of Addison disease can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.

Diagnosis

The healthcare provider will ask about your child’s symptoms and health history. He or she may also ask about your family’s health history. He or she will give your child a physical exam. Your child may have blood tests. These are done to check corticosteroid and potassium levels.

Treatment

The goal of treatment is to replace the hormones and to relieve the symptoms. Addison disease can be life-threatening. Because of this, treatment often starts right away with corticosteroid medicine. This medicine may be taken by mouth. Or it may be given by IV. It depends on how sick your child is. In most cases, corticosteroid medicine must be taken for life. Treatment may also include a medicine that helps manage the body's levels of sodium and potassium.

Complications

If left untreated, Addison disease may lead to:

• Severe abdominal pain
• Extreme weakness
• Low blood pressure
• Kidney failure
• Shock from dehydration

Severe complications are most likely to occur when the child is under physical stress.

Lack of adrenal hormones may also cause:

• High blood levels of potassium, which affect the water and sodium levels in the body
• Extreme sensitivity to the hormone insulin, which may lead to low blood sugar levels

Living with

Addison disease is a life-long condition. It needs lifetime treatment. Stressful events such as surgery, infection, or injury can cause severe symptoms of Addison. This is because corticosteroids help the body fight infection and keep healthy during physical stress. Talk with your child’s healthcare provider if your child needs surgery. Get medical care for your child right away if he or she:

• Has vomiting or diarrhea
• Has any other infection or illness

Your child should wear a medical alert bracelet or necklace. Managing your child’s chronic illness can be stressful for all members of the family.  Let your healthcare provider know if you, your child with Addison disease, or other family members need help dealing with the physical, emotional, and financial issues that the illness can cause.

When to Call a Healthcare Provider

If your child has Addison disease, talk with your child’s healthcare provider if your child needs surgery. Get medical care for your child right away if he or she:
