Different types of eating disorders

Whilst my eating disorder was developing, I was mainly in denial about what was happening to me however after a few months of making myself purge after eating particular foods I knew that my behaviours were not healthy or normal. I had cut all unhealthy foods out of my diet however I did not lose very much weight at first, which I think was due to the fact that my body tried to stay at the weight I was at so my metabolism just got slower and slower the less I ate. 
At the time I didn't know much about eating disorders so as soon as I started to think I was suffering from one, I instantly thought it was bulimia as I was making myself sick. Now I can see that it was actually more likely purge type anorexia that I was suffering from, which then changed to restrictive type anorexia when I got fed up with going through the pain associated with making myself sick and not losing very much weight at all. 

It really is surprising just how little weight I lost at first even though I practically halved my calorie intake and started exerising more as well. I would not say that I had food binges in this time, instead I just made mysef sick after eating any foods that I had previously decided I was no longer allowed to eat or if I ate a particularly unhealthy meal. 
When I went to hospital, one psychologist even said that I had EDNOS as I was restricting my intake so severely but was not classified as severely underweight. I do not think that I ever did have EDNOS, I just think that my weight had not yet dropped significantly low because I had not been severely restricting my intake for a long time before my doctor took action and had me admitted.
I know that it really does not matter what type of eating disorder I had at first. Perahaps it was bulimia, or purge type anorexia, heck maybe it was EDNOS? All eating disorders are terrible for the sufferer and life threatening, no matter what they may be called. At the time, I honestly hated making myelf purge more than I hated restricting once my restictive type anorexia developed. 
Making myself vomit is the most awful and painful thing I have ever done. I remember that I just used to cry and cry whilst I was making myself sick because it hurt so much, both mentally and physically. I would not let myself stop until I was convinvced that I no longer had anything left in my stomach. Never think that your eating disorder is not serious because IT IS, no matter what type of eating disorder you have.
No mattter what type of eating disorder you are suffering from, it is important that you try and get better.  No one deserves to live a life with an eating disorder. You desere to live a healthy and happy life that is not regimented or controlled by your weight and food. If you cant get better yourself, please try and get some help from a professional or someone you trust. The following descriptions from this website describe the key differences between different eating disorders.   

Anorexia Nervosa
'Anorexia nervosa' literally means 'loss of appetite for nervous reasons' but this is misleading, as in most cases the appetite of the sufferer is undiminished but is systematically unsatisfied. Individuals with anorexia nervosa are unwilling or unable to maintain a body weight that is normal or expected for their age and height (most clinicians' use 85% of normal weight as a guide). The disorder is characterised by a fear of gaining weight, self-starvation, and a distorted view of body image. Concerns and perceptions about their weight have an extremely powerful influence and impact on their self-evaluation and anorectics typically restrict the amount eaten and drunk, often to a dangerous level. Exercise may be used to burn off what are perceived to be excess calories. The seriousness of the weight loss and its physical effects are minimised or denied

Diagnostic criteria of anorexia nervosa include two subtypes of the disorder that describe two distinct behavioural patterns. Individuals with the Restricting Type maintain their low body weight purely by restricting food intake and increased activity. Those with the Binge-Eating/Purging Type usually restrict their food intake but also regularly engage in binge eating and/or purging behaviours.

Initially the sufferer focuses on food in an attempt to cope with life; it becomes a way of demonstrating control over body weight and shape. Ultimately, however, the disorder itself takes control and the chemical changes in the body affect the brain and distort thinking, making it almost impossible to make rational decisions about food. People who suffer from anorexia often have low self-esteem and a tremendous need to control their surroundings and emotions. As the illness progresses, the sufferer will experience the exhaustion of starvation. Occasionally people die from the effects of anorexia, especially if it is untreated.


Bulimia Nervosa

It was only in 1979 that bulimia nervosa was recognised by doctors as an eating disorder in its own right. The term bulimia nervosa means literally 'the nervous hunger of an ox'. The hunger, however, is really an emotional need that cannot be satisfied by food alone. After binge-eating a large quantity of food to fill the emotional or hunger gap, there is an urge to immediately get rid of the food. Bulimia Nervosa is characterised by these episodes of binge eating (uncontrolled consumption of a large amount of food in a relatively short period of time) followed by an inappropriate "compensation" behaviour such as forced vomiting, laxative or diuretic abuse, a subsequent fast or period of food restriction, or excessive exercising.

Diagnostic criteria for Bulimia Nervosa also identify two sub-types of the disorder: purging and non-purging. Forced vomiting, or abuse of laxatives or diuretics, is considered "purging" whereas fasting or engaging in excessive exercise after a binge to compensate for the calories consumed is considered "non-purging". Sometimes the distinction between bulimia and the binge/purge type of anorexia is difficult to draw. However, if a patient meets all other criteria of anorexia nervosa, that is generally the diagnosis which is made.

Bulimia is more difficult for others to notice as the sufferer tends not to lose weight so dramatically, or their weight will fluctuate. People with bulimia may have demanding jobs that require them to be out-going and self-assured even when they feel inadequate inside. As with anorexia, people who develop bulimia become reliant on the control of food and eating as a way of coping with emotional difficulties in their life. During the binge episode, the individual experiences a loss of control. However, the sense of a loss of control is also followed by a short-lived calmness. The calmness is often followed by self-loathing. The cycle of overeating and purging usually becomes an obsession and is repeated often.

Eating Disorder Not Otherwise Specified (EDNOS)

Eating disorder not otherwise specified (EDNOS) is a diagnostic category of mental disorders that involve disordered eating patterns. It is described in the diagnostic manuals as a "category [of] disorders of eating that do not meet the criteria for any specific Eating Disorder". A diagnosis of EDNOS is frequently used for people who meet some, but not all, of the diagnostic criteria for anorexia nervosa or bulimia nervosa. For example, a person who shows almost all of the symptoms of anorexia nervosa, but who still has a normal menstrual cycle and/or body mass index, can be diagnosed with EDNOS. A sufferer may experience episodes of binging and purging, but may not do so frequently enough to warrant a diagnosis of bulimia nervosa. A person may also engage in binging episodes without the use of inappropriate compensatory behaviours; this is referred to as binge eating disorder. People diagnosed with EDNOS may frequently switch between different eating disorders, or may with time fit all diagnostic criteria for anorexia or bulimia.

EDNOS is a serious eating disorder, like anorexia and bulimia, with various subtypes (such as Binge Eating Disorder, Compulsive Overeating and Orthorexia Nervosa, as described below) and can have long-term consequences on the individual's physical health.


Binge Eating Disorder (BED)

Binge eating disorder is characterised by consuming large quantities of food in a very short period of time until the individual is uncomfortably full. It is similar to the eating disorder bulimia nervosa except the individuals do not use any form of purging following a binge. Additionally, people with bulimia are typically of normal weight or may be slightly overweight whereas people with binge eating disorder are typically overweight or obese. Individuals usually feel out of control during a binge episode, followed by feelings of guilt and shame. Many individuals who suffer with binge eating disorder use food as a way to cope with or block out feelings and emotions they do not want to feel. Individuals can also use food as a way to numb themselves, to cope with daily life stressors, to provide comfort or fill a void they feel within. Like all eating disorders, binge eating is a serious problem but can be overcome through proper treatment.

Binge eating disorder is similar to, but it is distinct from, compulsive eating. People with binge eating disorder do not have a compulsion to overeat and do not spend a great deal of time fantasising about food. On the contrary, some people with binge eating disorder have very negative feelings about food. As with other eating disorders, binge eating is an expressive disorder - that is, the disorder is an expression of a deeper, psychological problem.

Continual debate exists over whether binge eating disorder should have its own diagnosis. Some believe that it is a milder form, or subset of bulimia nervosa, but others argue that it is its own distinct disorder. Currently it is characterised under Eating Disorder Not Otherwise Specified (EDNOS), and the diagnostic manual simply states that ‘more research is needed’.


Compulsive Overeating

Compulsive overeating is characterised by an addiction to food. An individual suffering from compulsive overeating disorder engages in frequent episodes of uncontrolled eating, or binging, during which they may feel frenzied or out of control. They will eat much more quickly than is normal, and continue to eat even past the point of being uncomfortably full. Binging in this way is generally followed by a period of intense guilt feelings and depression. Unlike individuals with bulimia, compulsive overeaters do not attempt to compensate for their binging with purging behaviours such as fasting, laxative use or vomiting. Compulsive overeaters will typically eat when they are not hungry, spend excessive amounts of time and thought devoted to food, and secretly plan or fantasize about eating alone.

In addition to binge eating, compulsive overeaters can also engage in grazing behaviour, during which they return to pick at food over and over throughout the day. This will result in a large overall number of calories consumed even if the quantities eaten at any one time may be small. When a compulsive eater overeats primarily through binging, he or she can be said to have binge eating disorder. Where there is continuous overeating but no binging, then the sufferer has compulsive overeating disorder. Compulsive overeating almost always leads to weight gain and obesity, but not everyone who is obese is also a compulsive overeater.

Compulsive overeating is a maladaptive behaviour that may be used as a way to cope with stress, emotional conflicts and daily problems. Food is used to block out feelings and emotions. Excessive weight may act as a shield they can hide behind to avoid social interaction. Sufferers usually feel out of control and are aware their eating patterns are abnormal. Like bulimics, compulsive overeaters do recognise they have a problem. Compulsive overeating is a serious condition and needs professional support to ensure long-term recovery.


Orthorexia Nervosa

People who eat a normal amount of food, but become exceedingly obsessed with healthy eating, or strictly categorize normal foods or entire food groups as "safe" and "off-limits", may be referred to as having orthorexia. Orthorexia Nervosa is an obsession with a "pure" diet, where it interferes with a person's life. It becomes a way of life filled with chronic concern for the quality of food being consumed. When the person suffering with Orthorexia Nervosa slips up from wavering from their "perfect" diet, they may resort to extreme acts of further self-discipline including even stricter regimens and fasting.

"This transference of all of life's values into the act of eating makes orthorexia a true disorder. In this essential characteristic, orthorexia bears many similarities to the two well-known eating disorders anorexia and bulimia. Where the bulimic and anorexic focus on the quantity of food, the orthorexic fixates on its quality. All three give food an excessive place in the scheme of life." (Steven Bratman, M.D., October 1997). Although the word is entering the English lexicon, the psychiatric community has not officially recognized the condition.
