What causes anorexia nervosa?
The cause of anorexia nervosa is not known. Anorexia usually begins as innocent dieting behavior, but gradually progresses to extreme and unhealthy weight loss. Social attitudes toward body appearance, family influences, genetics, and neurochemical and developmental factors are considered possible contributors to the cause of anorexia. Adolescents who develop anorexia are more likely to come from families with a history of weight problems, physical illness, and other mental health problems, such as depression or substance abuse.Further, often teens with the disorder come from families that are challenged by appropriate problem solving, being too rigid, overly-critical, intrusive, and overprotective. Teens may also be dependent, immature in their emotional development, and are likely to isolate themselves from others. Other mental health problems such as anxiety disorders or affective disorders are commonly found in teens with anorexia.
