Moon Face: Causes, Symptoms, and Connection to Cushing's Syndrome

A moon face is a rounded face caused by fluid retention and fatty tissue deposits. It is a common sign of Cushing's syndrome, a condition in which the body produces too much of the hormone cortisol. Cushing's syndrome can be caused by a tumor of the pituitary gland or adrenal glands, or it can be caused by certain medications, such as steroids.
