Anorexia nervosa has the highest mortality rate of all psychiatric disorders, with more than 10% of people who suffer from it will die. Anorexia nervosa is an eating disorder that is characterized by severe dietary restriction, excessive exercise and body dysmorphia, which make those suffering from it believe that they are overweight. Anorexia nervosa is often misunderstood by the general public. Research has refuted many of the previous ideas about anorexia nervosa. According to scientific research, anorexia nervosa has a genetic factor, is not just an adolescent disorder, and recovery is not just about gaining weight. Movies, TV shows, and magazines portray the thin woman as the ideal image of beauty. And the demographic considered the most impressive is tweens and teens. It seems that this is how popular thought has linked these two things, in order to blame popular culture for anorexia nervosa. However, what is little known is that anorexia nervosa long predates today's view of female beauty. The symptoms of anorexia nervosa were first described by Sir Richard Morton in 1689 (Kaplan). Then, in 1874, a doctor named William Gull named this disorder anorexia nervosa (Till). Although doctors and researchers agree that society can influence those who suffer from this disorder, it is not the reason for the disorder. In search of more effective treatment and prevention of anorexia nervosa, researchers have studied genetic risk factors for anorexia nervosa. Researchers used twin studies to learn more about a possible genetic link.
