A number of factors may play a role in the development of anorexia nervosa. Genetics, hormones, and brain structure may predispose a person to developing an eating disorder. Other risk factors include perfectionism, impulsivity, mood disorders, and a negative self-image. A history of being bullied, sexually abused, or experiencing eating problems or obesity as a child could also increase the risk of anorexia.[1] [2] Social media use and sociocultural beauty ideals have also been identified as potential contributing factors.[3][4]
