What psychological condition is characterized by extreme concerns about weight and body shape?

Anorexia nervosa is characterized by an intense fear of gaining weight and a distorted body image, leading to extreme dietary restrictions, excessive weight loss, and an unhealthy perception of one's body shape and size. Individuals with this condition often see themselves as overweight even when they are underweight, which drives compulsive behaviors related to eating and body management.

This disorder is not just about extreme dieting; it also involves a deep psychological struggle with self-esteem and body image. Anorexia nervosa frequently coexists with other mental health conditions, such as anxiety and depression, and requires a comprehensive approach for effective treatment. In contrast, other conditions listed—such as bulimia nervosa, binge-eating disorder, and body dysmorphic disorder—have distinct features that do not align exclusively with the intense concerns about weight and body shape captured by anorexia nervosa.
