Cushing's Syndrome is a hormonal disorder caused by prolonged exposure to high levels of cortisol, a hormone produced by the adrenal glands. This condition can result from various factors, including tumors on the adrenal glands or pituitary gland, or the use of corticosteroid medications. Symptoms often include weight gain, particularly around the abdomen and face, high blood pressure, and mood changes. Diagnosis typically involves blood tests, urine tests, and imaging studies to identify the source of excess cortisol. Treatment options may include surgery, radiation, or medication to control cortisol production, depending on the underlying cause of the syndrome.
