Adrenal fatigue, also called adrenal insufficiency, is a condition in which there is an insufficient production of hormones from the adrenal glands, located just above the kidneys. This can cause a variety of symptoms, such as weakness and fatigue, body aches, muscle or joint pain and feeling light-headed.

Adrenal fatigue, also called adrenal insufficiency or Addison's disease, is a condition that occurs when your adrenal glands do not produce enough of certain hormones that your body needs to function well.
Your adrenal glands are located on top of each kidney. Adrenal glands produce several hormones including cortisol, aldosterone and androgens that are important for the function of your heart, immune system, bones and nervous system.
Adrenal insufficiency occurs when your immune system attacks and destroys your adrenal glands. Adrenal insufficiency may be caused by adrenal glands not functioning properly in people who are under mental, emotional or physical stress.
Adrenal insufficiency is rare but can be life-threatening, particularly if symptoms are acute (Addisonian crisis). Adrenal insufficiency can affect men and women of any age, and it commonly affects individuals who are 30 to 50 years old.
