Cushing syndrome is a rare endocrine disorder characterized by changes in fat deposit patterns and symptoms such as a persistent headache, high blood pressure, and blood sugar, muscle weakness, irregular periods in women and sexual dysfunction in men. The cause for this is prolonged exposure of the body tissues to abnormally high levels of glucocorticoids. This may be in the form of the hormone cortisol which is produced by the adrenal glands.
The level of glucocorticoids may also be raised artificially by taking certain medications. Cortisol is a vital hormone that helps maintain homeostasis. It regulates metabolism and inflammatory response and maintains the levels of blood sugars and water in the body. Hence, an excess of cortisol causes a disturbance in crucial physiological processes, producing a variety of symptoms throughout the body.
