The disease is characterized by weight loss, muscle weakness, fatigue, low blood pressure, and sometimes darkening of the skin in both exposed and nonexposed parts of the body. Addison's disease occurs when the adrenal glands do not produce enough of the hormone cortisol and in some cases, the hormone aldosterone. For this reason, the disease is sometimes called chronic adrenal insufficiency, or hypocortisolism.
In most cases, Addison's disease occurs when the body's immune system mistakenly attacks the adrenal glands causing slowly progressive damage to the adrenal cortex. Signs & Symptoms The symptoms of Addisonâs disease can vary from one individual to another. Symptoms usually develop slowly over time and are usually vague and common to many conditions (nonspecific). This often leads to delays in the proper diagnosis of Addisonâs disease.
