Anorexia Nervosa Disorder commonly referred to in-short as “Anorexia” is an eating disorder characterized by a loss fifteen percent or more of original body weight. The psychiatric diagnosis of Anorexia Nervosa applies to persons refusing to maintain a body weight considered appropriate for a person's age and height. Intense and obsessive fear of gaining weight, and more specifically becoming obese, leads to extreme weight control measures including: self-induced starvation, vomiting, purging, and abuse of diuretic drugs, diet pills, and even such dangerous appetite-suppressing amphetamines as cocaine. Anorexia Nervosa Disorder stems from contributing genetic factors, depression, low self-esteem, and distorted body image.
