Cushing's syndrome is a disorder caused due to the body's long-term exposure to an excess level of the hormone cortisol.
The common cause of Cushing's syndrome is due to long-term, high-dose use of cortisol-like glucocorticoids.
Cushing's Syndrome is also caused due to pituitary tumor which causes excess production of ACTH (adrenocorticotropic hormone) which results in excess production of cortisol by the adrenal gland.
Also, the adrenal tumor produces an excess amount of cortisol
Some of the signs of Cushing's syndrome are weight gain and fatty tissue deposits, thin arms, and legs, round face, increased fat around the base of the neck, etc.
Complications of Cushing's Syndrome include heart attack and stroke, and blood clots in the legs and lungs.
