Cushing’s disease is a rare condition that is caused when the body is exposed to high hormone cortisol for a long period. Also known as hypercortisolism, this disease is usually caused when the body produces too much cortisol hormone. Cortisol is a hormone that is essential for the smooth functioning of the body and is made by the adrenal glands.

Cushing’s disease is a condition in which there is an excess production of the hormone cortisol in the body. The adrenal and pituitary glands do not function normally. Usually, people do experience high levels of cortisol hormone at least once in their lifetime, however, in the case of Cushing’s disease, the levels remain high for an extended period.
