Certainly. Anorexia nervosa is an eating disorder characterized by a distorted body image, low body weight, and an obsesive fear of gaining weight. One characteristic of most disease-related obsessions is that the obsessed one often does not recognize the obsession, but believes he or she is applying a valid view of reality. While others may suspect anorexia nervosa in a freind or acquaintance, it is possible that other causes are at work. Such suspicions should be referred to experts for complete diagnosis. Non-experts acting on such suspicions can be as damaging as the suspected disease in some cases.
