Overview, Causes, & Risk Factors
Cushing's syndrome is a hormonal disorder that occurs when the body tissues are exposed to high levels of the hormone cortisol. The adrenal glands produce cortisol. Cushing's disease is the most common type of Cushing's syndrome. It is caused by a noncancerous tumor of the pituitary gland.
What is going on in the body?
Cushing's syndrome occurs when body tissues are exposed to high levels of cortisol for a long time. Cortisol is an important hormone that regulates many body functions, including stress management. A part of the brain known as the hypothalamus sends CRH, a hormone, to the pituitary gland. The pituitary gland then produces another hormone called ACTH. The ACTH then stimulates the adrenal glands to produce cortisol. The hypothalamus and pituitary monitor blood levels of cortisol. They adjust their hormone release as needed. This maintains a normal balance of cortisol.
Sometimes the cortisol balance in the body is thrown off. The person may have excess cortisol under the following conditions:
What are the causes and risks of the disease?
Cushing's syndrome occurs when body tissues are exposed to high levels of cortisol over a long period of time. These high levels may be caused by:
Symptoms & Signs
What are the signs and symptoms of the disease?
Signs and symptoms of Cushing's syndrome vary but may include:
Diagnosis & Tests
How is the disease diagnosed?
Diagnosis of Cushing's syndrome begins with a medical history and physical exam. The healthcare provider may order additional tests, including:
Prevention & Expectations
What can be done to prevent the disease?
Many times, Cushing's syndrome cannot be prevented. Judicious use of glucocorticoid medicines is important. Many times, however, high levels are needed to control diseases.
What are the long-term effects of the disease?
If Cushing's syndrome is untreated, body tissues continue to be exposed to high cortisol levels. The person may develop the following conditions:
What are the risks to others?
Cushing's syndrome is not contagious and does not put others at risk.
Treatment & Monitoring
What are the treatments for the disease?
Treatment of Cushing's syndrome varies, depending on the source of the excess cortisol. Treatment options include:
What are the side effects of the treatments?
Surgery may cause bleeding, infection, or allergic reaction to anesthesia.
What happens after treatment for the disease?
Some individuals may produce less steroid hormones. They may need steroid hormones after treatment to maintain normal levels.
How is the disease monitored?
Someone with Cushing's syndrome will have regular visits with the healthcare provider. The provider may order periodic blood and urine tests to monitor the problem. Any new or worsening symptoms should be reported to the provider.
