Anorexia is a medical term for a loss of appetite. While the term outside of the scientific literature is often used interchangeably with anorexia nervosa, many possible causes exist for a loss of appetite, some of which may be harmless, while others indicate a serious clinical condition or pose a significant risk.
An eating disorder is a mental disorder defined by abnormal eating behaviors that negatively affect a person's physical or mental health. Types of eating disorders include binge eating disorder, where the patient eats a large amount in a short period of time; anorexia nervosa, where the person has an intense fear of gaining weight and restricts food or overexercises to manage this fear; bulimia nervosa, where individuals eat a large quantity (binging) then try to rid themselves of the food (purging); pica, where the patient eats non-food items; rumination syndrome, where the patient regurgitates undigested or minimally digested food; avoidant/restrictive food intake disorder (ARFID), where people have a reduced or selective food intake due to some psychological reasons; and a group of other specified feeding or eating disorders. Anxiety disorders, depression and substance abuse are common among people with eating disorders. These disorders do not include obesity. People often experience comorbidity between an eating disorder and OCD. It is estimated 20–60% of patients with an ED have a history of OCD.
Bulimia nervosa, also known as simply bulimia, is an eating disorder characterized by binge eating followed by purging or fasting, and excessive concern with body shape and weight. This activity aims to expel the body of calories eaten from the binging phase of the process. Binge eating refers to eating a large amount of food in a short amount of time. Purging refers to the attempts to get rid of the food consumed. This may be done by vomiting or taking laxatives.
Orthorexia nervosa (ON) is a proposed eating disorder characterized by an excessive preoccupation with eating healthy food. The term was introduced in 1997 by American physician Steven Bratman, M.D. He suggested that some people's dietary restrictions intended to promote health may paradoxically lead to unhealthy consequences, such as social isolation; anxiety; loss of ability to eat in a natural, intuitive manner; reduced interest in the full range of other healthy human activities; and, in rare cases, severe malnutrition or even death.
Obsessive–compulsive personality disorder (OCPD) is a cluster C personality disorder marked by a spectrum of obsessions with rules, lists, schedules, and order, among other things. Symptoms are usually present by the time a person reaches adulthood, and are visible in a variety of situations. The cause of OCPD is thought to involve a combination of genetic and environmental factors, namely problems with attachment.
Binge eating disorder (BED) is an eating disorder characterized by frequent and recurrent binge eating episodes with associated negative psychological and social problems, but without the compensatory behaviors common to bulimia nervosa, OSFED, or the binge-purge subtype of anorexia nervosa.
The Eating Attitudes Test, created by David Garner, is a widely used 26-item, standardized self-reported questionnaire of symptoms and concerns characteristic of eating disorders. The EAT is useful in assessing "eating disorder risk" in high school, college and other special risk samples such as athletes. EAT has been extremely effective in screening for anorexia nervosa in many populations.
Diabulimia, also known as ED-DMT1 in the US or T1ED in the UK, is an eating disorder in which people with type 1 diabetes deliberately give themselves less insulin than they need or stop taking it altogether for the purpose of weight loss. Diabulimia is not recognized as a formal psychiatric diagnosis in the DSM-5. Because of this, some in the medical or psychiatric communities use the phrases "disturbed eating behavior" or "disordered eating behavior" and disordered eating (DE) are quite common in medical and psychiatric literature addressing patients who have type 1 diabetes and manipulate insulin doses to control weight along with exhibiting bulimic behavior.
Purging disorder is an eating disorder characterized by the DSM-5 as self-induced vomiting, or misuse of laxatives, diuretics, or enemas to forcefully evacuate matter from the body. Purging disorder differs from bulimia nervosa (BN) because individuals do not consume a large amount of food before they purge. In current diagnostic systems, purging disorder is a form of other specified feeding or eating disorder. Research indicates that purging disorder, while not rare, is not as commonly found as anorexia nervosa or bulimia nervosa. This syndrome is associated with clinically significant levels of distress, and that it appears to be distinct from bulimia nervosa on measures of hunger and ability to control food intake. Some of the signs of purging disorder are frequent trips to the bathroom directly after a meal, frequent use of laxatives, and obsession over one's appearance and weight. Other signs include swollen cheeks, popped blood vessels in the eyes, and clear teeth which are all signs of excessive vomiting.
Maudsley family therapy also known as family-based treatment or Maudsley approach, is a family therapy for the treatment of anorexia nervosa devised by Christopher Dare and colleagues at the Maudsley Hospital in London. A comparison of family to individual therapy was conducted with eighty anorexia patients. The study showed family therapy to be the more effective approach in patients under 18 and within 3 years of the onset of their illness. Subsequent research confirmed the efficacy of family-based treatment for teens with anorexia nervosa. Family-based treatment has been adapted for bulimia nervosa and showed promising results in a randomized controlled trial comparing it to supportive individual therapy.
Anorexia nervosa (AN), often referred to simply as anorexia, is an eating disorder characterized by low weight, food restriction, body image disturbance, fear of gaining weight, and an overpowering desire to be thin.
Cognitive remediation is designed to improve neurocognitive abilities such as attention, working memory, cognitive flexibility and planning, and executive functioning which leads to improved psychosocial functioning.
The differential diagnoses of anorexia nervosa (AN) includes various types of medical and psychological conditions, which may be misdiagnosed as AN. In some cases, these conditions may be comorbid with AN because the misdiagnosis of AN is not uncommon. For example, a case of achalasia was misdiagnosed as AN and the patient spent two months confined to a psychiatric hospital. A reason for the differential diagnoses that surround AN arise mainly because, like other disorders, it is primarily, albeit defensively and adaptive for, the individual concerned. Anorexia Nervosa is a psychological disorder characterized by extremely reduced intake of food. People with anorexia nervosa have a low self-image and consider themselves overweight.
Cognitive behavioral therapy (CBT) is derived from both the cognitive and behavioral schools of psychology and focuses on the alteration of thoughts and actions with the goal of treating various disorders. The cognitive behavioral treatment of eating disorders emphasizes on the minimization of negative thoughts about body image and the act of eating, and attempts to alter negative and harmful behaviors that are involved in and perpetuate eating disorders. It also encourages the ability to tolerate negative thoughts and feelings as well as the ability to think about food and body perception in a multi-dimensional way. The emphasis is not only placed on altering cognition, but also on tangible practices like making goals and being rewarded for meeting those goals. CBT is a "time-limited and focused approach" which means that it is important for the patients of this type of therapy to have particular issues that they want to address when they begin treatment. CBT has also proven to be one of the most effective treatments for eating disorders.
Drunkorexia is a colloquialism for anorexia or bulimia combined with an alcohol use disorder. The term is generally used to denote the utilization of extreme weight control methods to compensate for planned binge drinking. Research on the combination of an eating disorder and binge drinking has primarily focused on college-aged women, though the phenomenon has also been noted among young men. Studies suggest that individuals engage in this combination of self-imposed malnutrition and binge drinking to avoid weight gain from alcohol, to save money for purchasing alcohol, and to facilitate alcohol intoxication.
Chew and spit is a compensatory behavior associated with several eating disorders that involves chewing food and spitting it out before swallowing, often as an attempt to avoid ingesting unwanted or unnecessary calories. CS can be used as a way to taste food viewed as “forbidden” or unhealthy. Individuals who partake in CS typically have an increased desire for thinness, increased loss of control (LOC) and body dissatisfaction. CS can replace vomiting and/or binging behaviors, or serve as an additional behavior to many eating disorders.
Kate Tchanturia is a British psychologist who is a professor of psychology in eating disorders at the Institute of Psychiatry, Psychology and Neuroscience, King’s College London. She is also Consultant Psychologist at the South London and Maudsley NHS Foundation Trust for the National Eating Disorder Service. Her main research interests include cultural differences in illness presentations, cognitive profiles in eating disorders, and experimental work in emotion processing and translational research from experimental findings to real clinical practice. Tchanturia has a particular interest in women’s mental health and has pioneered the PEACE pathway for autism and eating disorder comorbidity.
Paul E. Garfinkel is a Canadian psychiatrist, researcher and an academic leader. He is a professor at the University of Toronto and a staff psychiatrist at Centre for Addiction and Mental Health (CAMH).
Body image disturbance (BID) is a common symptom in patients with eating disorders and is characterized by an altered perception of one's own body.
Atypical anorexia nervosa is an eating disorder in which individuals meet all the qualifications for anorexia nervosa, including a body image disturbance and a history of restrictive eating and weight loss, except that they are not currently underweight. Atypical anorexia qualifies as a mental health disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), under the category Other Specified Feeding and Eating Disorders (OSFED). The characteristics of people with atypical anorexia generally do not differ significantly from anorexia nervosa patients except for their current weight.
