Anorexia nervosa
This is an excerpt from the paper...
Anorexia nervosa is an eating disorder in which people intentionally starve themselves because of an irrational fear of gaining weight (Levey, Williams-Wilson and Corfman, 2030; National, 1993). Individuals with this disorder also have a distorted perception of their body shape and size and see it as much larger than it really is. Anorexia nervosa has a long history, being described more than 300 years ago by Richard Morton in 1689 as a condition of "Nervous Consumption" which he attributed to "sadness, and anxious Cares". In 1873, physicians described it as "hysteria linked to hypochondriasis" and "a perversion of the ego" and the conditions became officially known by its current name of anorexia nervosa. Early in the 20th century, it was considered a purely psychological disorder, then it was proposed that a pituitary disorder led to weight loss in some of these patients, and others considered it a physiological disturbance with a psychological etiology. Various theories of the cause of anorexia nervosa were elaborated, such as Bruch's view that mothers failed to confirm their child's independence needs, causing inner confusion and leading to an overestimate of their body size and an inability to recognize signals from the body regarding appetite, hunger, satiety, affective states and sexual feelings (Levey, Williams-Wilson and Corfman, 2005). Bruch also held that self-starvation represented a struggle for autonomy, control, competence and self-respe

exia nervosa has also increased during that time, and perhaps out of proportion to the increase in the disorder itself, say Keel and Klump (2003). The disease has been around for many years, but has become more talked about only in recent years.
The mortality from anorexia nervosa is fairly high, being between six percent and 20 percent (Levey, Williams-Wilson and Corfman, 2030). Death is usually secondary to starvation or suicide. Anorexia nervosa also causes many other serious medical complications. In the cardiovascular system, it can cause arrhythmia, bradycardia and hypotension (Anorexia, 2005). Roughly one third of anorexia nervosa patients have mild anemia, and leukopenia occurs in up to 50 percent of these patients. Normal movement of the gastrointestinal tract slows down when eating is severely restricted and the dehydration associated with anorexia nervosa results in highly concentrated urine. Polyuria may develop when the kidneys' ability to concentrate urine decreases. Amenorrhea is a classic symptom of anorexia nervosa, when a menstrual period is missed for three or more consecutive months and no other reason can be found. There may be reduced levels of growth hormones and retarded growth in some cases.
