The adrenal glands control many body functions and play a critical role in the resistance to stress. If an individual has experienced a great deal of stress or has taken corticosteroids for a long period of time, the adrenal glands will shrink and not perform properly, causing the person to experience anxiety, depression, or chronic fatigue.
An abnormal adrenal response-either deficient or excessive hormone release-significantly alters an individual’s response to stress. Often the adrenals become “exhausted” as a result of constant demands placed upon them. An individual with adrenal exhaustion will usually suffer from chronic fatigue, may complain of feeling stressed out or anxious, and will typically have a reduced resistance to allergies and infection. Atrophy of the adrenal cortex is a common side effect of continual stress or cortisone administration.
