causes of adrenal fatigue
There are 4 main categories of causes for adrenal fatigue: Neurological, Biochemical, Physical, and Mental/Emotional, each with their own types of chronic and acute stressors. Under Brain/Neurological, there is an overactive-right brain, meaning that the right brain has more connections to the stress response system (the flight-or-fight) system.
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 unproven theory behind adrenal fatigue is that your adrenal glands are unable to keep pace with the demands of perpetual fight-or-flight arousal.
