How do I tell if a high cortisol level isn’t just from stress?
There are several approaches that your doctor can take. The simplest involves repeating tests at a time when you feel less stressed. Your doctor can also give you varying doses of a medicine that replaces cortisol (usually dexamethasone) to see if this decreases your cortisol level. Multiple tests are often needed to tell if stress or disease is causing a high cortisol level.
