Eating disorders develop due to a combination of societal, familial, and individual factors that influence self-image and identity. People with eating disorders use disordered eating behaviors as an unhealthy coping mechanism to deal with emotions and feel a sense of control. Eating disorders are serious mental illnesses characterized by extreme concern with body weight and shape that can significantly interfere with daily life activities and well-being. Common eating disorders include anorexia nervosa, bulimia nervosa, binge eating disorder, and compulsive overeating. Warning signs include low self-esteem, social withdrawal, preoccupation with food and weight, and denial of the problem's severity.
