Anorexia Nervosa Overview
Anorexia Nervosa which is often just referred to as anorexia is a type of eating disorder. It is a psychological disorder which can produce many medical problems. Anorexia Nervosa can be considered a kind of “out-of-control” dieting. The U.S. National Institute of Mental Health (NIMH) says an estimated 0.5% to 3.7% of women will suffer from this disorder at some point in their lives.

Body Image Issues
Disturbances in the way in which one’s body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or denial of the current low body weight. i.e. believing you are fat when you are not, making your weight the only thing you judge yourself on, denying medical seriousness of your low weight.
