Cushing syndrome occurs due to abnormally high levels of the hormone cortisol. This can happen for a variety of reasons. The most common cause is overuse of corticosteroid medications.
Your doctor may recommend several different diagnostic tests and treatments. In most cases, medication can help you manage your cortisol levels.
Cushing syndrome is also known as Cushing’s syndrome or hypercortisolism.
The most common symptoms of this condition are:
Men may also have:
Children with this condition are generally obese and have a slower rate of growth.
Your adrenal glands produce cortisol. It helps with a number of your body’s functions, including:
Your body may produce high levels of cortisol for a variety of reasons, including:
The most common cause of Cushing syndrome is the use of corticosteroid medications, such as prednisone, in high doses for a long period. Doctors can prescribe these medications to prevent rejection of a transplanted organ. They also use them to treat inflammatory diseases, such as lupus and arthritis. High doses of injectable steroids for treatment of back pain can also cause this syndrome.
Other causes include:
Familial Cushing syndrome is another possible cause. Cushing syndrome isn’t typically inherited, but it’s possible to have an inherited tendency to develop tumors of the endocrine glands.
Cushing syndrome can have many different causes. The diagnosis is made based on abnormal cortisol levels in the body. Your doctor will perform a physical examination and review your medical history and symptoms. They may also order laboratory tests, including:
After you receive the diagnosis of this condition, your doctor must still determine the cause of the excess cortisol production. Tests to help determine the cause may include a corticotropin-releasing hormone stimulation test and a high-dose dexamethasone suppression test. They may also order imaging studies, such as CT and MRI scans.
Treatment will depend on the cause. Your doctor may prescribe a medication to help. Some medications decrease cortisol production in the adrenal glands or decrease ACTH production in the pituitary gland. Other medications block the effect of cortisol on your tissues.
If you use corticosteroids, a change in medication or dosage may be necessary. Don’t attempt to change the dosage yourself. You should do this under close medical supervision.
If you don’t get treatment for it, Cushing syndrome can lead to:
Cushing syndrome due to pituitary tumors can interfere with the production of other hormones.
The sooner you begin treatment, the better the expected outcome. It’s important to note that your individual outlook depends on the specific cause and treatment you receive.
It may take a long time for your symptoms to improve. Be sure to ask your doctor for healthy dietary guidelines, keep follow-up appointments, and increase your activity level slowly.
Support groups can help people cope with Cushing syndrome. Your local hospital or doctor can provide you with information about groups that meet in your area.
