Lack of corticosteroids in the blood may cause the pituitary gland to produce more corticotropin hormones to stimulate the adrenal glands. Since corticotrophin affects melanin production, excess levels of corticotropins may cause dark pigmentation of the skin and lining of the mouth.
Addison's disease is the result of an underactive adrenal gland. An underactive adrenal gland produces insufficient amounts of cortisol and aldosterone. Cortisol is a steroid hormone that helps to control the body's use of fats, proteins, and carbohydrates, suppresses inflammatory reactions in the body, and affects immune system functions. Aldosterone is a steroid hormone that controls sodium and potassium in the blood. Addison's disease is considered rare. Onset of this disease may occur at any age.
Destruction of the adrenal gland due to an autoimmune response is the most common cause of the disease. Some Addison's disease cases are caused by the actual destruction of the adrenal glands through cancer, infection, or other diseases. Other causes may include:
Lack of adrenal hormones may cause:
Mild Addison's disease symptoms may only be apparent when the patient is under physical stress. The following are the most common symptoms of Addison's disease. However, each individual may experience symptoms differently. Symptoms may include:
If not treated, Addison's disease may lead to severe abdominal pain, extreme weakness, low blood pressure, kidney failure, and shock—especially when the patient is experiencing physical stress.
The symptoms of Addison's disease may resemble other conditions or medical problems. Always consult your doctor for a diagnosis.
In addition to a complete medical history and medical examination, diagnostic procedures for Addison's disease may include:
The goal of treatment is to restore the adrenal glands to normal function, producing normal levels of corticosteroid hormones. Specific treatment for Addison's disease will be determined by your doctor based on:
Since Addison's disease can be life threatening, treatment often begins with administration of corticosteroids. Corticosteroids, such as prednisone, may be taken orally or intravenously, depending on the patient's condition. Usually the patient has to continue taking the corticosteroid the rest of his or her life. Treatment may also include taking fludrocortisone, a drug that helps restore the body's normal levels of sodium and potassium.
