When under stress, we produce and release short bursts of cortisol into the bloodstream. The adrenals are two small glands that sit on top of the kidneys and produce several hormones, among them, cortisol. An attractive theory, called adrenal fatigue, links stress exposure to adrenal exhaustion as a possible cause of this lack of energy. It can be frustrating for clinicians and patients when a clear-cut diagnosis remains elusive. Doctors engage in detective work, obtaining a medical history, doing a physical exam, and doing blood tests. Despite being so common, it is often challenging to come up with a diagnosis, as many medical problems can cause fatigue. Low energy and tiredness are among the most common reasons patients seek help from a doctor.
