Step-by-step explanation:
Cushing syndrome is a disorder characterized by the overproduction of the hormone cortisol, often caused by a pituitary tumor that secretes excessive cortisol or adrenocorticotropic hormone (ACTH). This disorder can lead to various symptoms such as obesity, high blood pressure, diabetes, excessive hair growth, and depression. One distinctive sign is the appearance of stretch marks and a rounded face, known as a 'moon face'. Treatment options for Cushing syndrome depend on the cause and may include surgery or medication to reduce cortisol levels.
