Defining characteristics of Anorexia Nervosa:

Individuals with anorexia nervosa are unwilling or unable to maintain a body weight that is normal or expectable for their age and height (most clinicians use 85% of normal weight as a guide). Individuals with anorexia nervosa typically display a pronounced fear of weight gain and a dread of becoming fat although they are dramatically underweight. Concerns and perceptions about their weight have a extremely powerful influence and impact on their self-evaluation. The seriousness of the weight loss and its physical effects is minimized or denied  (women with the diagnosis of anorexia nervosa have missed at least three consecutive menstrual cycles).

Diagnostic criteria of anorexia nervosa include two subtypes of the disorder that describe two distinct behavioral patterns. Individuals with the Restricting Type maintain their low body weight purely by restricting food intake and increased activity (i.e. compulsive exercise). Those with the Binge-Eating/Purging Type usually restrict their food intake but also regularly engage in binge eating and/or purging behaviors (i.e. self-induced vomiting or the misuse of laxatives, diuretics or enemas). Binge-Eating/Purging Type of Anorexia Nervosa is also frequently associated with other impulse control problems and mood disorders. 

People who suffer from anorexia often have low self-esteem and a tremendous need to control their surroundings and emotions. The eating disorder is often a reaction to external and internal conflicts (i.e. anxiety, stress, and unhappiness can be leading factors).


Profile: Anorexia Nervosa

The person suffering Anorexia is generally extremely sensitive about being fat, or has an intense fear of becoming fat, and of losing control over the amount of food he/she eats.  This hyper-sensitivity is accompanied by the desire to control his/her emotions and reactions to these emotions. Low self-esteem and the constant need for acceptance leads to obsessive dieting and starvation as a way to control not only weight, but also feelings and actions regarding their emotions. Many anorexics feel they are not deserving of life's gifts and pleasures.  They often deprive themselves of situations that offer pleasure. Starvation or restriction, obsessive exercise, calorie counting, a constant obsession with food and health issues, self-induced vomiting, the use of excessive amounts of laxative, diuretics, and/or diet pills, and a persistent concern with body image can all be some of the physical indications that someone suffers from Anorexia Nervosa. People suffering with Anorexia may also go through periods of Bulimia (binging and purging) as well.

There are numerous ways a person with Anorexia can exhibit their disorder. The anorexic attempts to maintain strict control over food/caloric intake. Periods of starvation, obsessive counting of calories, compulsive exercising, and/or purging after meals are among the most common symptoms. In some cases, an anorexic will seem to eat normal meals with only periods of restriction. They use diet pills to control their appetite, or laxatives to attempt to rid their body of food, both of which are dangerous and useless in producing weight loss results. Anorexics will deny hunger, make excuses to avoid eating, will often hide food they claim to have eaten, or attempt to purge the food away with self-induced vomiting, or by taking laxatives.


Diagnostic Criteria: Anorexia Nervosa

The following definition of Anorexia Nervosa is used to assist mental health professionals in making a clinical diagnosis. The clinical criteria is not always representative of what one living with anorexia feels. Please note, you can still suffer from Anorexia even if one of the below signs is not present. One can not simply read the criteria and think "I don't have one of the symptoms, so I am not Anorexic" or "I don't have a problem with food."

1. Refusal to maintain body weight at or above a minimally normal weight for age and height (e.g., weight loss leading to maintenance of body weight less than 85% of that expected; or failure to make expected weight gain during period of growth, leading to body weight less than 85% of that expected).

2. Intense fear of gaining weight or becoming fat, even though underweight.

3. Disturbance 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 seriousness of the current low body weight.

4. In postmenarcheal females (the absence of at least three consecutive menstrual cycles.

Restricting Type: during the current episode of Anorexia Nervosa, the person has not regularly engaged in binge-eating or purging behavior (i.e., self-induced vomiting or the misuse of laxatives, diuretics, or enemas).
