The symptoms of anorexia nervosa can be severe and, in some cases, deadly. Without treatment, between 5-20% of individuals with anorexia nervosa will die. With eating disorder treatment, this number decreases to 2-3%. Typically, anorexia nervosa appears in early to mid-adolescence, and it also disproportionately affects women.
