While there is no single known cause of anorexia, several things may contribute to the development of the disorder. For example, social influences, genetic and biological factors, psychological issues, and family environments all contribute to the development of Anorexia.
Social influences are a big contribution to anorexia. The American society places high value on thinness among women. Thinness is frequently mistaken or identified as beauty. As a result, young girls often think that they must be slender to be attractive. Kids are deluged with images of fat free bodies in the pages of heath, fashion, and teen magazines. Such media that feature photographs of thin super models and actresses are under attack for encouraging young women to starve themselves.
One factor possibly leading to anorexia nervosa is the way a person looks at the world, or the psychological factors. An anorexic might have a fear of growing up, a drive to be perfect, or family problems. Some psychological characteristics are low self-esteem, poor body image, need for control, and the need to feel special or unique.
Additional contributions to anorexia are family environments. Some families of people with the disorder are more likely to be overprotective, rigid, and suffocating in their closeness. Also parents who place too much value on appearance, diet themselves, and criticize their children's bodies
