Explanation / Answer

Cushing's syndrome is a hormonal disorder caused by prolonged exposure of the body's tissue to high levels of the hormone cortisol. Sometimes called hypercortisolism, Cushing's syndrome is relatively rare and most commonly affects adults aged 20 to 50. People who are obese and have type 2 diabetes, along with poorly controlled blood glucose also called blood sugar and high blood pressure.

Normally the production of cortisol follows a precise chain of events. First the hypothalamus a part of the brain sends corticotropin-releasing hormone to the pituitary gland. CRH causes the pituitary to secrete ACTH which stimulates the adrenal glands. When these glands receive the ACTH, they respond by releasing cortisol into the bloodstream.

Treatment depends on the specific reason for excess cortisol and may include surgery, radiation, chemotherapy or the use of cortisol-inhibiting drugs.
