During which eating disorder do periods of anorexia typically occur?

In the context of eating disorders, the correct response identifies that periods of anorexia typically occur in Bulimia Nervosa. Individuals with Bulimia Nervosa often engage in cycles of binge eating followed by compensatory behaviors such as self-induced vomiting, excessive exercise, or fasting. During the fasting or compensatory phases, these individuals can exhibit symptoms similar to anorexia, including significant weight loss, an intense fear of gaining weight, and a distorted body image.

While Anorexia Nervosa is primarily characterized by a significantly reduced food intake and an intense fear of weight gain, it does not typically involve the binge-eating episodes seen in Bulimia Nervosa. Binge Eating Disorder is characterized by episodes of binge eating without subsequent purging behaviors, and Pica involves consuming non-nutritive, non-food substances. Hence, Bulimia Nervosa is the only disorder in which periods of anorexia-style behavior fit within the binge-purge cycle.
