Eating Disorders: Anorexia Nervosa, Bulimia Nervosa and Binge Eating Disorder


Eating disorders are characterized by a disorder related to food. This psychopathology that presents in various forms can appear at any age but mainly affects teenagers, especially girls. It can be connected to another psychiatric disorder such as depression, and psychosis (delusions of poisoning) or reflects a functioning borderline and / or addictive. The psychological and social characteristics include intense fear of eating in the presence of others, diets low in carbohydrates and fat, concern for the food, laxative abuse and lies. In this essay, I explore the psychological and biological causes of these disorders to arrive at a treatment model that can best manage them.

Causal Factors

There is no single cause of eating disorders. In all probability, anorexia nervosa and bulimia nervosa result from the complex interaction of biological, socio-cultural, family, and individual variables. The eating disorders are classified as a disorder of Axis I in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) published by the American Psychiatric Association (APA). There are many causes a psychological factor of eating disorders, some of these cases meet the criteria for the diagnosis of Axis I or personality disorder coded in Axis II and is comorbid with diagnosed eating disorder. The Axis II disorders are subtypes of "groups", A, B and C. The cause between personality disorders and eating disorders must be fully established Strict dieting and deprivation triggers binge eating, followed by purging to undo the caloric intake and emotional fear of weight gain, followed by shame and disgust, followed by strict dieting.

There is an increased risk of anorexia nervosa among first-degree relatives of persons with the disorder and perhaps with depression. Individuals with certain psychological styles (low self-esteem, perfectionism, obsessiveness) and from families with certain characteristics (rigidity, over involvement, and poor communication, high achievement demands) may be particularly susceptible to western society's pervasive emphasis on thinness as the ideal.

Associated Symptoms

Associated eating disorder symptoms can be classified by categories, including situational (e.g. avoiding an unpleasant activity), physiological (e.g. reduction of hunger), psychological (e.g. experiencing a sense of accomplishment by losing weight), and interpersonal (e.g. expressed concern from others). Some of the most common symptoms include:

Indulgence in lots of high calorie foods.

Withdrawal of food intake

Dental problems - Tooth decay, stained teeth and bad breath.



Sense of secretiveness.

The Neural Basis

In order to understand the neural basis for body-image disturbance, we need to find out about how a mental image of the body is constructed in normal development. Such a complex representation of the body will encompass visual, tactile, vestibular, soma sensory and visceral perceptual information, matched against stored template memories (King and Hopkins, 2008).

It is sometimes difficult to ascertain whether these symptoms reflect secondary effects of the starvation or the coexistence of psychiatric disorders. Frequent medical findings include leukopenia (decrease in white blood cells) and anemia, dehydration, hypercholesterolemia, abnormal liver and thyroid functions, electrolyte imbalances, low estrogen levels (females), osteoporosis, and cardiovascular ...
