Adrenal fatigue is a term applied to a collection of nonspecific symptoms, such as body aches, fatigue, nervousness, sleep disturbances and digestive problems.
Your adrenal glands produce a variety of hormones that are essential to life. The medical term adrenal insufficiency (Addison's disease) refers to inadequate production of one or more of these hormones as a result of an underlying disease.
Signs and symptoms of adrenal insufficiency may include:
- Body aches
- Unexplained weight loss
- Low blood pressure
- Loss of body hair
- Skin discoloration (hyperpigmentation)
Adrenal insufficiency can be diagnosed by blood tests and special stimulation tests that show inadequate levels of adrenal hormones.
Proponents of the adrenal fatigue diagnosis claim this is a mild form of adrenal insufficiency caused by chronic stress. The theory behind adrenal fatigue is that your adrenal glands are unable to keep pace with the demands of perpetual fight-or-flight arousal. As a result, they can't produce quite enough of the hormones you need to feel good.
