Your doctor will talk to you first about your medical history and your signs and symptoms. If your doctor thinks that you may have Addison's disease, you may undergo some of the following tests:
- Blood test. Measuring your blood levels of sodium, potassium, cortisol and ACTH gives your doctor an initial indication of whether adrenal insufficiency may be causing your signs and symptoms. A blood test can also measure antibodies associated with autoimmune Addison's disease.
- ACTH stimulation test. This test involves measuring the level of cortisol in your blood before and after an injection of synthetic ACTH. ACTH signals your adrenal glands to produce cortisol. If your adrenal glands are damaged, the ACTH stimulation test shows that your output of cortisol in response to synthetic ACTH is limited or nonexistent.
- Insulin-induced hypoglycemia test. Occasionally, doctors suggest this test if pituitary disease is a possible cause of adrenal insufficiency (secondary adrenal insufficiency). The test involves checking your blood sugar (blood glucose) and cortisol levels at various intervals after an injection of insulin. In healthy people, glucose levels fall and cortisol levels increase.
- Imaging tests. Your doctor may have you undergo a computerized tomography (CT) scan of your abdomen to check the size of your adrenal glands and look for other abnormalities that may give insight to the cause of the adrenal insufficiency. Your doctor may also suggest an MRI scan of your pituitary gland if testing indicates you might have secondary adrenal insufficiency.
All treatment for Addison's disease involves hormone replacement therapy to correct the levels of steroid hormones your body isn't producing. Some options for treatment include:
- Oral corticosteroids. Hydrocortisone (Cortef), prednisone or cortisone acetate may be used to replace cortisol. Your doctor may prescribe fludrocortisone to replace aldosterone.
- Corticosteroid injections. If you're ill with vomiting and can't retain oral medications, injections may be needed.
An ample amount of sodium is recommended, especially during heavy exercise, when the weather is hot or if you have gastrointestinal upsets, such as diarrhea. Your doctor will also suggest a temporary increase in your dosage if you're facing a stressful situation, such as an operation, an infection or a minor illness.
An addisonian crisis is a life-threatening situation that results in low blood pressure, low blood levels of sugar and high blood levels of potassium. This situation requires immediate medical care. Treatment typically includes intravenous injections of:
- Saline solution
- Sugar (dextrose)

Coping and support
These steps may help you cope better with a medical emergency if you have Addison's disease:
- Carry a medical alert card and bracelet at all times. In the event you're incapacitated, emergency medical personnel know what kind of care you need.
- Keep extra medication handy. Because missing even one day of therapy may be dangerous, it's a good idea to keep a small supply of medication at work, at a vacation home and in your travel bag, in the event you forget to take your pills. Also, have your doctor prescribe a needle, syringe and injectable form of corticosteroids to have with you in case of an emergency.
- Stay in contact with your doctor. Keep an ongoing relationship with your doctor to make sure that the doses of replacement hormones are adequate, but not excessive. If you're having persistent problems with your medications, you may need adjustments in the doses or timing of the medications.
Preparing for your appointment
You're likely to start by seeing your family doctor or a general practitioner. However, in some cases when you call to set up an appointment, you may be referred to an endocrinologist.
Because appointments can be brief, and because there's often a lot of ground to cover, it's a good idea to be well-prepared for your appointment. Here's some information to help you get ready for your appointment, and what to expect from your doctor.
What you can do
- Be aware of any pre-appointment restrictions. At the time you make the appointment, be sure to ask if there's anything you need to do in advance, such as restrict your diet.
- Write down any symptoms you're experiencing, including any that may seem unrelated to the reason for which you scheduled the appointment.
- Write down key personal information, including any major stresses or recent life changes.
- Make a list of all medications, vitamins or supplements that you're taking.
- Take a family member or friend along, if possible. Sometimes it can be difficult to recall all the information provided to you during an appointment. Someone who accompanies you may remember something that you missed or forgot.
- Write down questions to ask your doctor.
Your time with your doctor is limited, so preparing a list of questions ahead of time will help you make the most of your time together. List your questions from most important to least important in case time runs out. For Addison's disease, some basic questions to ask your doctor include:
- What is likely causing my symptoms or condition?
- Other than the most likely cause, what are possible causes for my symptoms or condition?
- What kinds of tests do I need?
- Is my condition likely temporary or chronic?
- What is the best course of action?
- What are the alternatives to the primary approach that you're suggesting?
- I have these other health conditions. How can I best manage them together?
- Are there any restrictions that I need to follow?
- Should I see a specialist?
- Is there a generic alternative to the medicine you're prescribing me?
- Are there any brochures or other printed material that I can take home with me? What websites do you recommend?
In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask questions during your appointment.
What to expect from your doctor
Your doctor is likely to ask you a number of questions. Being ready to answer them may reserve time to go over any points you want to spend more time on. Your doctor may ask:
- When did you first begin experiencing symptoms?
- Have your symptoms been continuous or occasional?
- How severe are your symptoms?
- What, if anything, seems to improve your symptoms?
- What, if anything, appears to worsen your symptoms?
