A study on young Saudi adults was conducted to see how excessive stress and levels of physical activity influenced the development of adrenal fatigue.
The study which was published in the Journal of Physical Therapy Science examined adrenal fatigue score, levels of physical activity, and socioeconomic background of 160 Saudi subjects aged 15 to 22 years of age. The study found that stress and poor social background caused unfavorable changes in the adrenal hormone status resulting in adrenal fatigue syndrome.
However, this same study found that increasing levels of physical activity improved the subject’s well-being and mitigated uncomfortable symptoms. Another study on the relationship between the size of adrenal glands and chronic fatigue syndrome found that patients from a fatigue clinic that manifested chronic fatigue syndrome had adrenal glands 50% smaller than what would be considered normal suggesting that they had developed adrenal atrophy. This was one of the rare studies that found a correlation between unexplainable fatigue symptoms and adrenal gland functioning.
Other causes of adrenal fatigue are
