Doctors Explain Cortisol Causes, Risks, Myths, and Helpful Next Steps

Cortisol is a hormone that can become too high or too low.

Doctors say long-term use of steroid medicines is the most common cause of very high cortisol.

Less often, a tumor in the adrenal glands or pituitary gland can cause high cortisol.

A high cortisol test by itself does not mean a person has cancer.

Low cortisol can also be dangerous.

Addison’s disease is one condition linked with low cortisol.

People who take steroid medicines for a long time may be more likely to have abnormal levels.

People with adrenal or pituitary problems may also be at higher risk.

Anyone concerned about cortisol should speak with a medical professional.
