There is also decreased secretion of gastrointestinal enzymes, which results in anorexia, nausea and vomiting, flatulence, and diarrhea. These symptoms, as well as anxiety, depression, and loss of mental acuity, have been correlated with the absence of the peaks of cortisol output that normally occur every 24 hours.

bruising in areas of injury, ecchymoses where there has been no trauma, and petechiae.
