Read Genes May Be Responsible for Anorexia,Too Anorexia nervosa is an eating disorder in which a person has an exaggerated concern with being overweight. This fixation on weight typically leads to inadequate food consumption and excessive exercising. Severe cases of anorexia have led to drastic weight loss and even starvation. Typically, anorexia nervosa has been considered a psychosocial disorder with a cognitive component associated with self-image. Recently Dorothy Grice, MD, a researcher at the University of Pennsylvania’s Department of Psychiatry and Center for Neurobiology and Behavior has found evidence linking anorexia and certain genes.
