What Causes High Cortisol Symptoms?
Rarely, having too much cortisol is caused by Cushing disease—a hormone-secreting tumor of the adrenal gland. More often, however, high cortisol is caused by prescription corticosteroid medications (including corticosteroid injections into the joints).[4]
Even more commonly, too much cortisol is caused by chronic stress. Chronic stress dysregulates the body’s stress response system—the hypothalamic–pituitary-adrenal (HPA) axis.
The HPA axis is a critical physiological system that mediates responses to all types of physical and psychological stress. When that stress is chronic, the delicate feedback system that is the HPA axis becomes damaged.[5] This can result in chronically high cortisol levels and lead to high cortisol symptoms.
Certain conditions are well known to cause the types of chronic physical and psychological stress that damage the HPA axis and lead to high cortisol levels. These conditions, which are often associated with high cortisol symptoms, include [6]:
-
Depression
-
Panic disorder
-
Generalized anxiety disorder
-
Posttraumatic stress disorder
-
Anorexia nervosa
-
Bulimia nervosa
-
Alcoholism
-
Diabetes mellitus
-
Severe obesity
-
Metabolic syndrome
-
Polycystic ovary syndrome (PCOS)
-
Obstructive sleep apnea syndrome
-
Shift work
-
End-stage kidney disease
-
Major life stressors
-
Chronic pain
What to Do About High Levels of Cortisol
The fortunate news for those with too much cortisol is that many effective treatment options are available, including natural cortisol-lowering therapies. The correct treatment depends on the underlying cause and may involve anything from surgical removal of the adrenal glands (in the case of true Cushing disease caused by an adrenal tumor) to diet and lifestyle therapies aimed at resetting the dysfunctional HPA axis.
If you’re suffering from high levels of cortisol, eat at regular intervals (every few hours) and follow a diet that is higher in lean protein and fiber and lower in carbohydrates that have a high glycemic index (especially sugar). These dietary changes are important for lowering cortisol levels, as is the regular practice of relaxation or mind-body techniques such as meditation or progressive muscle relaxation.[7] Start by actively practicing one of these relaxation techniques just a few minutes a day and gradually increase the time to 20 to 30 minutes.
