Identify two eating disorders and describe the symptoms that characterize these disorders
What will be an ideal response?
a . In anorexia nervosa, a disorder found almost exclusively in women, fear of weight gain leads to self-starvation or eating and purging, with such consequences as low blood pressure and heart disease. Sufferers possess a distorted body image. b. The criteria for bulimia nervosa include eating large quantities of high-caloric foods at least twice weekly for three months, feeling a loss of control over eating, and following eating with compensatory behaviors: self-induced vomiting, purging, or fasting. Much more prevalent than anorexia, bulimia is unrelated to an individual's weight. Binges tend to be related to negative emotions. c. Binge-eating disorder is similar to bulimia nervosa; however, the binge eating is not following by vomiting, excessive exercise, or fasting (i.e., compensatory behaviors).
