Ans. (D)
Hyperglycemia is not seen in eating disorders and would suggest an alternate diagnosis for weight loss such as diabetes. Hypoglycemia and low estrogens and gonadotropins are frequently seen in anorexia nervosa (AN). BUN and creatinine may be elevated. Hypochloremia, hypokalemia, and alkalosis are frequently seen in BN.
