Which of the following is NOT considered an eating disorder?

Post-traumatic stress disorder (PTSD) is not classified as an eating disorder. Instead, it is recognized as a mental health condition that can occur after someone has experienced or witnessed a traumatic event. The symptoms of PTSD may include flashbacks, nightmares, severe anxiety, and uncontrollable thoughts about the event, but it does not specifically relate to issues around food intake or body image, which are the central features of eating disorders.

In contrast, anorexia nervosa, bulimia nervosa, and binge eating disorder are all categorized as eating disorders. Anorexia nervosa involves extreme restriction of food intake leading to significant weight loss, while bulimia nervosa is characterized by episodes of binge eating followed by purging behaviors to prevent weight gain. Binge eating disorder is marked by recurrent episodes of consuming large quantities of food without the compensatory behaviors seen in bulimia. Each of these disorders directly impacts eating habits, self-perception related to body weight, and overall health, distinguishing them from PTSD.
