What Is Anorexia Nervosa

Anorexia nervosa is an eating disorder characterized by an irrational fear of food as well as extreme, life-threatening weight loss. Patients who suffer from anorexia nervosa have a distorted body image and an excessive, obsessive fear of obesity, even when they are significantly underweight. Patients with anorexia nervosa do not necessarily lose their appetite but rather obsessively control and restrict their food intake.

Anorexia nervosa is classified as a mental illness. It starts most often during a persons teenage years or young adulthood. According to the National Association of Anorexia Nervosa and Associated Disorders, between 85 and 90% of those who suffer from this dangerous psychological disorder are female.

Spotting An Eating Disorder In A Loved One

Different eating disorders have some different features – for instance, to be diagnosed with anorexia you must be underweight. However, it’s absolutely possible to have an eating disorder without being grossly underweight. In fact, people with orthorexia are often also obsessed with being in perfect physical shape, so may be extremely fit and look very healthy.

Warning signs include:

  • Making excuses not to eat in company.
  • Wearing baggy clothes to hide their shape.
  • Secret stashes of unhealthy food or laxatives.
  • Locking themselves in the bathroom after meals or at other times.
  • Becoming distressed if you try to talk to them about eating.
  • Being very concerned that others in the family eat lots.
  • Being very fussy about their food.
  • Cutting out whole food groups – gluten, lactose, any form of processed foods, animal products, etc.
  • Insisting on doing the food shopping, and spending long periods looking at he food nutritional labels.
  • Being short-tempered or irritable.

Temporal Instability And Diagnostic Transitions

Longitudinal follow-up studies of anorexia and bulimia nervosa have found that a significant proportion of subjects change diagnostic status to another eating disorder ,,,,,. Diagnostic crossovers are more common in the initial years of illness and follow a predictable sequence. Typically, restrictive anorexia nervosa mutates into binge eating/purging anorexia nervosa, before crossing over to bulimia nervosa ,,,,. Crossover in the opposite direction is less common. While one-third of individuals with an initial diagnosis of anorexia nervosa develop bulimia nervosa during a five-to-ten year follow-up, only 10-15% of those with an initial diagnosis of bulimia nervosa develop anorexia ,,. Larger proportions of subjects with an initial diagnosis of bulimia nervosa develop binge eating disorder or eating disorder not otherwise specified ,. There are also numerous transitions between specific eating disorder categories and EDNOS, with the latter often representing an intermediate state on the way to recovery ,,.

The diagnostic transitions may also extend to a relationship between feeding disorders in childhood and eating disorders in adolescence and adulthood. Restrictive eating and hyperactivity are often present in children and adolescents who deny any motivation of these behaviours by fear of gaining weight, but who later demonstrate weight phobia and receive a diagnosis of an eating disorder ,,.

The Status Quo: Classification Of Bulimic

Eating disorder : Classification and tratment


The current diagnostic criteria for BN are shown in Table  . As can be seen, BN is characterized by recurrent episodes of binge eating and extreme weight-control behaviors . Binge eating entails, first, the consumption of an objectively large amount food in a discrete period of time and, second, a sense of loss of control over eating during the episode. Extreme weight-control behaviors include self-induced vomiting, misuse of laxatives or diuretics, extreme dietary restriction and excessive exercise. Recurrent is defined as at least twice weekly during the past 3 months. That is, episodes of both binge eating and extreme weight control behaviors need to occur at this frequency for the DSM diagnosis of BN to be considered.

Common Types Of Eating Disorders

Although the term eating is in the name, eating disorders are about more than food. Theyre complex mental health conditions that often require the intervention of medical and psychological experts to alter their course.

These disorders are described in the American Psychiatric Associations Diagnostic and Statistical Manual of Mental Disorders, fifth edition .

In the United States alone, an estimated 20 million women and 10 million men have or have had an eating disorder at some point in their life .

This article describes 6 of the most common types of eating disorders and their symptoms.

Eating disorders are a range of psychological conditions that cause unhealthy eating habits to develop. They might start with an obsession with food, body weight, or body shape.

In severe cases, eating disorders can cause serious health consequences and may even result in death if left untreated.

Those with eating disorders can have a variety of symptoms. However, most include the severe restriction of food, food binges, or purging behaviors like vomiting or over-exercising.

Although eating disorders can affect people of any gender at any life stage, theyre most often reported in adolescents and young women. In fact, up to 13% of youth may experience at least one eating disorder by the age of 20 .

Summary Eating disorders are mental health conditions marked by an obsession with food or body shape. They can affect anyone but are most prevalent among young women.

Types Of Eating Disorders

A serious, potentially life-threatening eating disorder characterized by self-starvation and excessive weight loss.


  • Food restriction leading to significantly low body weight in the context of age, sex, development, and physical health

  • Intense fear of weight gain or becoming fat

  • Persistent behavior interfering with weight gain despite low weight, such as fasting or excessive exercise

  • Disturbed experience of ones body weight or shape, influenced by self-evaluation or persistent lack of recognizing the seriousness of current low body weight

  • Restricting behavior or binge eating and purging behaviors

Medical Complications and Associated Features

  • Signs of depression, such as depressed mood, social withdrawal, irritability, insomnia, and diminished interest in sex

  • Obsessive-compulsive features, both related and unrelated to food

  • Elevated suicide risk
  • Delayed puberty, lack of development

  • Hormonal imbalance

  • Gastrointestinal complications such as stomach aches, bloating, constipation, and acid reflux

  • Vital sign disturbances, such as dangerously low blood pressure

  • Loss of and/or weakened heart muscle

  • Heart palpitations and chest pain

  • Bradycardia or tachycardia

  • Heart failure

  • Edema

Diagnostic And Statistical Manual

Previously considered a topic for further research exploration, binge eating disorder was included in the in 2013. Until 2013, binge eating disorder was categorized as an , an umbrella category for eating disorders that don’t fall under the categories for anorexia nervosa or bulimia nervosa. Because it was not a recognized psychiatric disorder in the until 2013, it has been difficult to obtain insurance reimbursement for treatments. The disorder now has its own category under DSM-5, which outlines the signs and symptoms that must be present to classify a person’s behavior as binge eating disorder. Studies have confirmed the high predictive value of these criteria for diagnosing BED.

According to the World Health Organization’s ICD-11 classification of BED, the severity of the disorder can be classified as mild , moderate , severe and extreme .

One study claims that the method for diagnosing BED is for a clinician to conduct a structured interview using the DSM-5 criteria or taking the Eating Disorder Examination. The Structured Clinical Interview takes no more than 75 minutes to complete and has a systematic approach which follows the DSM-5 criteria. The Eating Disorder Examination is a semi-structured interview which identifies the frequency of binges and associated eating disorder features.

Getting Help For An Eating Disorder

If you think you may have an eating disorder, see a GP as soon as you can.

A GP will ask about your eating habits and how you’re feeling, plus check your overall health and weight.

They may refer you to an eating disorder specialist or team of specialists.

It can be very hard to admit you have a problem and ask for help. It may make things easier if you bring a friend or loved one with you to your appointment.

You can also talk in confidence to an adviser from eating disorders charity Beat by calling their adult helpline on 0808 801 0677 or youth helpline on 0808 801 0711.

Binge Eating Disorder: When Comfort Eating Crosses The Line

Eating for comfort or emotional reasons is not necessarily a bad thing. That is as long as the food does not become the main source of comfort or method for dealing with lifes stress and challenges. Using food to consistently soothe emotional upheaval can quickly become Binge Eating Disorder, and this can result in some serious health consequences.

Elimination Of Not Otherwise Specified

In DSM-5, the diagnostic category Not Otherwise Specified has been replaced by two designations: Other Specified and Unspecified. This change applies to all psychiatric diagnoses, including eating disorders. If one is unable to specify one of the established listed diagnoses, such as Anorexia Nervosa, for example, one may diagnose by preceding the general category with or above. In this case, a clinician might choose Other Specified Feeding and Eating Disorder or Unspecified FED .

How Are Eating Disorders Diagnosed

Doctors use guidelines for diagnosing different mental health conditions, such as eating disorders. When deciding on a diagnosis doctors will look at these guidelines. They will look at what symptoms you have had. And how long you have had these for. The main guidelines are:

  • International Classification of Diseases , produced by the World Health Organisation , and
  • Diagnostic and Statistical Manual , produced by the American Psychiatric Association.

A health professional will assess you to work out if they think you have an eating disorder. As part of the assessment they will:

  • ask about your feelings, thoughts and behaviours,
  • see if there has been any rapid weight loss,
  • check if your body mass index is too high or too low,
  • ask you about any diets that you are on,
  • listen to the concerns that your family or carers have about your eating behaviour, and
  • think about different reasons for your symptoms.

Outcome: Difficult To Predict

(PDF) ARFID: A new eating disorder classification

Long-term studies will help define the outcome for patients with OSFED and UFED. Several long-term studies of outcome of patients with EDNOS, such as that of Ben-Tovim et al. , could not reach a conclusion about outcome; treatment did not affect outcome. Another large study by Scheuing et al of patients with eating disorders , 74% of whom had type 1 diabetes, underscored the importance of making the diagnosis. Patients with BN and EDNOS had a two-fold higher risk of diabetic retinopathy; this was not seen in AN patients. In an analysis of outcomes of eating disorders treatment, Keel and Brown in 2010 found similar 5-year outcomes for patients with BN and EDNOS. They also reported that 75% of EDNOS patients recovered; however, the other 25% had chronic courses of disease.

Description Of Study Design

This was an experimental, vignette-based case-controlled study implemented via the internet with participation from a large, global, multilingual, and multidisciplinary sample of mental health professionals. The current study is part of a larger research program that employs a standard research design across the range of mental and behavioral disorders to assess the impact and clinical utility of proposed changes in the ICD guidelines. Additional information about the rationale and experimental design for these studies has been published elsewhere .

Breaking 5 Myths Of Binge Eating

Binge Eating Disorder is the most common of all the eating disorders but incongruently, with the least treatment options for the sufferers. Until recently, BED was not even recognized as an actual disorder and could not be found in the Diagnostic and Statistical Manual published by The American Psychiatric Association.

Medical Nutrition Therapy For Bed

Professional treatment for binge eating disorder will involve the collaboration of multiple professionals, including a therapist/counselor, medical doctor, psychiatrist, and registered dietitian. Each of these professionals works in their area of specialty to help address a concern that a person with binge eating disorder is facing.

Classification Of Eating Disorders

Eating disorders are classified into different types, according to the Diagnostic and Statistical Manual of Mental Disorders , Fifth Edition. Classifications are made based on the presenting symptoms and how often these occur, and include:

  • Binge eating disorder
  • Other specified feeding or eating disorders
  • Bulimia nervosa 
  • Avoidant/restrictive food intake disorder
  • Unspecified feeding or eating disorder
  • Pica
  • Rumination disorder

Other Specified Feeding And Eating Disorders

Other Specified Feeding and Eating Disorders was previously known as Eating Disorder Not Otherwise Specified in past editions of the Diagnostic and Statistical Manual. Despite being considered a catch-all classification that was sometimes denied insurance coverage for treatment as it was seen as less serious, OSFED/EDNOS is a serious, life-threatening, and treatable eating disorder. The category was developed to encompass those individuals who did not meet strict diagnostic criteria for anorexia nervosa or bulimia nervosa but still had a significant eating disorder. In community clinics, the majority of individuals were historically diagnosed with EDNOS.Common Signs & Symptoms:Because OSFED encompasses a wide variety of eating disordered behaviors, any or all of the following symptoms may be present in people with OSFED.

  • Frequent episodes of consuming very large amount of food followed by behaviors to prevent weight gain, such as self-induced vomiting
  • Evidence of binge eating, including disappearance of large amounts of food in short periods of time or lots of empty wrappers and containers indicating consumption of large amounts of food
  • Self-esteem overly related to body image
  • Dieting behavior
  • Expresses a need to burn off calories taken in
  • Evidence of purging behaviors, including frequent trips to the bathroom after meals, signs and/or smells of vomiting, presence of wrappers or packages of laxatives or diuretics

What Are Symptoms Of Different Eating Disorders

Anorexia nervosa

Anorexia nervosa is characterized by an intense fear of gaining weight or of becoming fat.

  • Even though the person has a significantly low weight, they have a constant fear of putting on weight.
  • Symptoms persist for at least 3 months at a time.
  • The two subtypes of anorexia nervosa are
  • Restricting anorexia nervosa: Weight loss is accomplished primarily through dieting, fasting, and excessive exercise.
  • Binge-eating or purging anorexia nervosa: Weight loss is accomplished through reduced eating and episodes of self-induced vomiting or taking laxatives, diuretics , or enemas.

Bulimia nervosa

Bulimia nervosa is characterized by:

  • A cycle of binge eating and inappropriate compensatory behaviors .
  • Symptoms appear at least once a week and last for at least 3 months.
  • Based on the number of episodes a week, the disorder is classified as mild, moderate, or severe.

Binge eating disorder

  • Binge eating disorder is when there are recurrent episodes of binge eating but without compensatory behaviors . It is characterized by:
  • Eating much more rapidly than normal.
  • Eating until feeling uncomfortably full.
  • Eating large amounts of food when not hungry.
  • Eating alone because of embarrassment around eating habits.
  • Feeling disgusted with oneself, depressed or guilty.


Pica is the persistent eating of nonnutritive, nonfood substances for at least one month.

Rumination disorder

Rumination disorder is characterized by repeated regurgitation of food for at least one month.

  • Consistent.

Ufed: Cases That Dont Fit Into Any Categories

The DSM-5 category Unspecified Feeding or Eating Disorder is reserved for patients who dont fit any of the above 5 categories, or for whom there is not enough information to make a specific OSFED diagnosis. Several studies have analyzed the DSM-5 change from EDNOS to the new categories. In one, a cooperative study at the University of Helsinki, Finland, and the University of North Carolina, Chapel Hill, the records off 2825 Finnish twins with significant eating disorder symptoms were screened. These women did not fit into the categories of AN, BN, or BED . Twenty-one percent of women with an ED fell into the OSFED/UFED category. One-third fulfilled OSFED criteria while two-thirds fit the UFED category. Women in both categories had clinically severe ED symptoms. The 5-year probability of recovery was 60%.

Other Specified Feeding Or Eating Disorder

Eating disorder : Classification and tratment

The majority of those with eating disorders do not fall within the guidelines for anorexia, bulimia and binge eating disorder and are classified as OSFED. To be diagnosed as having OSFED a person must present with a feeding or eating behaviors that cause clinically significant distress and impairment in areas of functioning, but do not meet the full criteria for any of the other feeding and eating disorders.

A diagnosis might then be allocated that specifies a specific reason why the presentation does not meet the specifics of another disorder . The following are further examples for OSFED:

Medical Complications and Associated Features

  • Weight loss or faltering growth

  • Generalized emotional difficulties, sometimes referred to as food avoidance emotional disorder

  • Mirroring of medical complications and associated features of anorexia nervosa

What Treatment Should I Be Offered

You can check what treatment and care is recommended for eating disorders on the National Institute for Health and Care Excellence website. NICE produce guidelines for how health professionals should treat certain conditions. You can download these from their website at But the NHS does not have to follow these recommendations. They should have a good reason for not following them.

Medication should not be offered as the only treatment for any eating disorder.

Physical treatments like acupuncture, weight training and yoga should not be offered as treatment for eating disorders.

There are different types of psychological treatments for eating disorders, and you may be offered a combination of these. All of the treatments will include guided self-help and psycho-education.

Guided self-help programmeThis is a self-help programme. You will look at the thoughts, feelings and actions that you have in relation to your eating. You should also have some short support sessions to help you follow the programme.

Psycho-educationPsycho-education means that you will learn about your symptoms and how to manage them.

How To Treat Eating Disorders

Due to the insidious ways in which eating disorders pervade all aspects of ones body, mind, and life, receiving the appropriate treatment is important. There are various levels of care designed to treat specific stages of eating disorder severitythese range from inpatient at a medical facility down to outpatient. Any eating disorder treatment center can assess a struggling individual to determine the appropriate level of care.

Outside of receiving treatment in general, it is also important to ensure the facility uses evidence-based practices, as these can lead to better long-term outcomes.

There are many evidence-based treatments that can support eating disorder recovery; the most well-known and most commonly used is Cognitive Behavioral Therapy , Dialectical Behavior Therapy , and Family-Based Treatment .

Do not be afraid to ask any questions that arise if you or a loved one are searching for the treatment that will best support recovery.

Depression And Binge Eating Disorder

Depression is commonly associated with eating disorders, and it is often co-occurring with Binge Eating Disorder . Trying to address Binge Eating Disorder can become more difficult if clinical depression is a key component or trigger for binge eating. This begs the question of Did binge eating begin because of depression or did depression begin because of binge eating?

Children Binge Eating: Different Stories But Similar Storylines

Binge eating is not only a concern for adults. Many children and adolescents have secret memories of having engaged in binge eating. These patterns are occurring ever more frequently in todays image-focused, diet-obsessed world. Read two stories about young adolescents who engaged in binge eating disorder behavior.

Binge Eating Disorder And Family Patterns Of Self

The factors that influence the development of binge eating disorder are complex and involve genetics , the environment of both your past and present, the social conditions you are exposed to, and much more. One aspect that that can also be influential in the development of BED is the nature of a family setting and the way in which children are taught to soothe themselves and cope with their emotions.

Summary And Future Directions

Eating disorders such as BED and AN exact a tremendous toll on society and those who have them. Nevertheless, additional research is needed to elucidate further the genetic and neurocircuit mechanisms that underlie these devastating disorders. As summarized here, both clinical studies from populations diagnosed with eating disorders and basic science studies on the neural circuitry that controls feeding and related behaviors are rapidly advancing our knowledge of the biological underpinnings of eating disorders. Further integration of these disparate fields of inquiry may provide a more holistic view of the neurobiological underpinnings of eating disorders. Next, we discuss experimental strategies to bridge the clinical and basic science further.

Bed Holistic Health And Weight Loss

Overweight binge eaters represent a collision of two traditional treatment worlds: eating disorders and weight control. 30-40% of those seeking weight loss treatment meet the criteria for BED. In a residential weight control treatment setting, this link between overweight/obesity and binge eating is striking. Our mean BMI is 43.3 and data suggest that 43.7 % of our participants have BED. A host of co-morbidities results from this combination of eating pathology and obesity.

Night Eating Syndrome: So Much More Than Just A Bedtime Snack


Night Eating Syndrome was first recognized in 1955 by American psychiatrist, Dr. Albert Stunkard. NES is an eating disorder in which the affected individual wakes several times in the middle of the night and is unable to fall back asleep without eating, even though he or she is not actually hungry. The food eaten is often unhealthy and calorie-dense.
