When a person is experiencing low cortisol symptoms they need to have blood tests done to determine their exact cortisol levels. A blood test will be done on potassium, sodium and ACTH levels as well as cortisol levels at the same time. To measure the ACTH levels the person must be given a shot of synthetic ACTH first. Then the doctor will test the cortisol levels. An MRI or CT scan may also be done so the doctor can see the condition of the adrenal glands and the pituitary gland. If the test shows the person does indeed have low cortisol levels the treatment for their low cortisol symptoms can include prescription medications. These medications are corticosteroids classified as hydrocortisones and are used to replace the cortisol that the body is not making.
