Adrenal insufficiency occurs when the adrenal glands of your body do not produce enough anti-stress steroid hormones such as cortisol, cortisone, aldosterone, noradrenaline and adrenaline. During the initial stage of less steroid secretion, your body experiences excess exhaustion. When high fatigue is experienced with other symptoms such as nausea, brain fog, drop in concentration level, difficulty in waking up, salt food cravings and inability to deal with stress; then the underlying condition may be adrenal fatigue syndrome. Conventional medicine does not recognize AFS. But when left untreated, AFS further advances to adrenal exhaustion and adrenal insufficiency or Addison’s disease, recognized by conventional medicine. Some of the symptoms of adrenal insufficiency include severe diarrhea or vomiting, high fever, profound weakness, shaking chills, nausea, unconsciousness, confusion or even coma. Though adrenal insufficiency is a rare condition, it requires immediate medical attention. The condition requires administration of artificial steroids that behave as natural steroids. However, artificial steroids can increase adrenal insufficiency when taken in high doses or for a longer duration - thus posing serious health risks.
