Eating disorders

What are eating disorders?

Eating disorders include anorexia nervosa, which involves a lack of maintaining normal weight, usually less than 85% of the expected weight, and an intense fear of gaining weight. Bulimia nervosa involves the presence of binge eating followed by compensatory behaviours to prevent weight gain, while binge eating disorder does not involve compensatory behaviour.
