Definition

Addison disease is problem with the adrenal glands. They make hormones that help the body with blood pressure, metabolism, and the immune system.

With Addison disease, the glands do not make enough of a hormone called cortisol. Aldosterone may also be low.

The disease may be:

• Primary—the glands can’t make hormones
• Secondary—other hormones that tell glands what to do are missing or low

A severe problem from this disease is the Addisonian or adrenal crisis. It can result in death.

Causes    TOP

Primary Addison disease is caused by problems with the outer layer of the gland. This can happen slowly over time.

Addison disease is most often caused when the immune system attacks the gland. It is not known why this happens.

Damage may also be caused by infections such as:

• Tuberculosis
• Cytomegalovirus (CMV) infection
• Fungal infections

Less common causes are:

• Some cancers
• Amyloidosis —build up of certain proteins in tissue
• Bleeding within the glands—may happen because of blood thinning drugs or shock
• Having the glands removed with surgery
• Genetic problems or birth defects that make it hard for the glands to work the right way
• Certain medicines

Secondary Addison disease can be caused by damage to the pituitary gland. This gland sends hormones that control the adrenal gland.

This disease may also happen after long term corticosteroids are stopped.

Treatment    TOP

Addison disease can’t be cured. Medicines can help replace the missing hormones and ease health problems from it. They can also help stop you from having adrenal crisis. You will need care right away if you have this.

Routine blood tests are needed when you are taking the drugs.

Wear an alert bracelet that states that you have this disease. This will let others know of your health problem if you can’t tell them yourself.
