Eating disorders are serious mental illnesses characterized by irregular eating habits and an excessive concern about body weight and shape, leading to the highest mortality rate among psychiatric disorders. Factors contributing to eating disorders include psychological issues, cultural pressures, and biological influences, with common types being anorexia nervosa, bulimia nervosa, and binge eating disorder. Effective treatment involves a multidisciplinary approach, addressing both the symptoms and underlying causes, while supporting long-term recovery and healthy relationships with food.
