DEFINITION
One of the eating disorder is anorexia nervosa, commonly referred to simply as anorexia, characterized by: * self-imposed starvation * refusal to maintain a healthy body weight, * an obsessive fear of gaining weight, even when they are underweight * a distorted self image.

If one twin has anorexia then the other has a 1 in 2 chance of getting it. This tells us that it has a tendency to run in some families and that the condition may have a genetic part. However,
