Cushing is a medical condition caused by excessive levels of the hormone cortisol in the body. This can result from various factors, including tumors on the pituitary gland or adrenal glands, or from taking certain medications. Symptoms often include weight gain, high blood pressure, and changes in mood. Diagnosis typically involves blood tests, urine tests, and imaging studies to identify the source of the excess cortisol. Treatment options may include surgery, radiation, or medication to manage hormone levels. Early detection and management are crucial to prevent complications associated with Cushing's syndrome.
