'''Eating disorders''' are serious [[mental health]] and medical conditions characterized by persistent disturbances in eating behavior, food intake, body weight regulation, or body image that cause significant physical, psychological, and social harm. Eating disorders are not lifestyle choices, vanity, weakness, or lack of willpower. They are complex illnesses influenced by genetic, biological, psychological, social, cultural, metabolic, and environmental factors.

Eating disorders can affect people of all ages, body sizes, genders, races, ethnicities, and socioeconomic backgrounds. A person does not have to be underweight to have a serious eating disorder. Many patients with [[bulimia nervosa]], [[binge eating disorder]], [[atypical anorexia nervosa]], [[night eating syndrome]], or [[other specified feeding or eating disorder]] may be normal weight, overweight, or obese while still having serious medical and psychological risk.

The [[National Institute of Mental Health]] describes eating disorders as serious and sometimes fatal illnesses involving severe disturbances in eating behaviors, and notes that obsessions with food, body weight, and shape may be signs of an eating disorder.{{cite web|url=https://www.nimh.nih.gov/health/topics/eating-disorders|title=Eating Disorders|publisher=National Institute of Mental Health|accessdate=June 25, 2026}} The [[American Psychiatric Association]] describes eating disorders as serious medical conditions involving severe and persistent disturbances in eating behaviors and associated distressing thoughts and emotions that impair psychosocial functioning.{{cite web|url=https://www.psychiatry.org/patients-families/eating-disorders/what-are-eating-disorders|title=What are Eating Disorders?|publisher=American Psychiatric Association|accessdate=June 25, 2026}}

'''[[W8MD Weight Loss, Sleep and MedSpa]] Centers''' can help patients by screening for eating disorders, identifying medical complications, recognizing unsafe dieting patterns, evaluating obesity-related binge eating, helping with [[binge eating disorder]], [[night eating syndrome]], [[emotional eating]], [[insulin resistance]], [[sleep apnea]], [[weight cycling]], and [[obesity]], and coordinating referrals to mental health, psychiatry, dietitian, or specialty eating-disorder programs when needed. Severe eating disorders such as medically unstable [[anorexia nervosa]], severe [[bulimia nervosa]], electrolyte abnormalities, suicidality, or rapid weight loss require urgent specialty care.

==Overview==
Eating disorders involve more than food. They often include distressing thoughts, emotions, and behaviors related to:

{{div col|colwidth=15em}}
* Food
* Eating
* Hunger
* Fullness
* Body weight
* Body shape
* Calories
* Exercise
* Control
* Shame
* Anxiety
* Depression
* Trauma
* Perfectionism
* Impulsivity
* Metabolic health
{{div col end}}

Eating disorders may lead to starvation, malnutrition, obesity, diabetes risk, electrolyte abnormalities, cardiac complications, digestive problems, infertility, bone loss, dental damage, depression, anxiety, and suicide risk.

==Major types of eating disorders==
The major feeding and eating disorders include:

{{div col|colwidth=15em}}
* [[Anorexia nervosa]]
* [[Bulimia nervosa]]
* [[Binge eating disorder]]
* [[Avoidant/restrictive food intake disorder]]
* [[Pica]]
* [[Rumination disorder]]
* [[Other specified feeding or eating disorder]]
* [[Unspecified feeding or eating disorder]]
{{div col end}}

Related or commonly discussed conditions include:

{{div col|colwidth=15em}}
* [[Orthorexia nervosa]]
* [[Night eating syndrome]]
* [[Purging disorder]]
* [[Atypical anorexia nervosa]]
* [[Subthreshold bulimia nervosa]]
* [[Subthreshold binge eating disorder]]
* [[Diabulimia]]
* [[Muscle dysmorphia]]
* [[Compulsive exercise]]
* [[Emotional eating]]
* [[Food addiction]]
* [[Disordered eating]]
{{div col end}}

StatPearls lists major eating disorder categories including anorexia nervosa, bulimia nervosa, binge eating disorder, avoidant/restrictive food intake disorder, pica, rumination, other specified feeding or eating disorders, night eating syndrome, atypical anorexia nervosa, purging disorder, orthorexia, and unspecified feeding or eating disorders.{{cite web|url=https://www.ncbi.nlm.nih.gov/books/NBK567717/|title=Eating Disorders|publisher=StatPearls, NCBI Bookshelf|accessdate=June 25, 2026}}

==Anorexia nervosa==
'''[[Anorexia nervosa]]''' is an eating disorder characterized by restriction of energy intake, significantly low body weight relative to age, sex, developmental trajectory, and physical health, intense fear of gaining weight, and disturbance in the way body weight or shape is experienced.{{cite web|url=https://www.ncbi.nlm.nih.gov/books/NBK459148/|title=Anorexia Nervosa|publisher=StatPearls, NCBI Bookshelf|accessdate=June 25, 2026}}

Common features include:

{{div col|colwidth=15em}}
* Severe food restriction
* Intense fear of weight gain
* Distorted body image
* Excessive weighing
* Avoidance of meals
* Ritualized eating
* Excessive exercise
* Amenorrhea or menstrual changes
* Cold intolerance
* Fatigue
* Hair thinning
* Low heart rate
* Low blood pressure
* Bone loss
{{div col end}}

Anorexia nervosa may be restricting type or binge-eating/purging type. It can be life-threatening and requires prompt medical and psychiatric care.

==Atypical anorexia nervosa==
'''[[Atypical anorexia nervosa]]''' has many features of anorexia nervosa, but the person’s weight may remain in or above the normal range despite significant weight loss and serious medical risk. This condition is often missed because clinicians or families may falsely assume that a person cannot be medically unstable unless underweight.

Warning signs include:

{{div col|colwidth=15em}}
* Rapid weight loss
* Severe dietary restriction
* Fear of weight gain
* Body image disturbance
* Dizziness
* Fainting
* Low heart rate
* Menstrual irregularity
* Excessive exercise
* Preoccupation with calories
{{div col end}}

==Bulimia nervosa==
'''[[Bulimia nervosa]]''' is characterized by recurrent episodes of binge eating followed by inappropriate compensatory behaviors to prevent weight gain, such as self-induced vomiting, laxative misuse, diuretic misuse, fasting, or excessive exercise. Bulimia can occur at any body weight.

Common signs include:

{{div col|colwidth=15em}}
* Binge eating episodes
* Feeling out of control while eating
* Self-induced vomiting
* Laxative or diuretic misuse
* Excessive exercise
* Shame after eating
* Swollen salivary glands
* Dental enamel erosion
* Sore throat
* Heartburn
* Electrolyte imbalance
* Irregular heartbeat
{{div col end}}

The 2023 American Psychiatric Association practice guideline recommends eating-disorder-focused cognitive behavioral therapy for adults with bulimia nervosa and also recommends a serotonin reuptake inhibitor such as fluoxetine 60 mg daily either initially or if there is minimal or no response to psychotherapy alone by six weeks.{{cite journal|last1=Crone|first1=C.|title=The American Psychiatric Association Practice Guideline for the Treatment of Patients With Eating Disorders|journal=American Journal of Psychiatry|year=2023|volume=180|issue=2|pages=167-171|doi=10.1176/appi.ajp.23180001|pmid=36722117}}

==Binge eating disorder==
'''[[Binge eating disorder]]''' is characterized by recurrent episodes of eating a large amount of food with a sense of loss of control, without regular compensatory purging behaviors. It is the most common eating disorder in many clinical settings and is strongly associated with [[obesity]], [[weight cycling]], [[insulin resistance]], [[prediabetes]], [[type 2 diabetes]], [[fatty liver disease]], [[sleep apnea]], depression, anxiety, and shame.

Features include:

{{div col|colwidth=15em}}
* Eating unusually large amounts of food
* Feeling unable to stop eating
* Eating rapidly
* Eating until uncomfortably full
* Eating when not physically hungry
* Eating alone due to embarrassment
* Feeling guilt, shame, or disgust afterward
* No regular purging behavior
{{div col end}}

DSM-5-TR criteria include binge eating at least once weekly for three months without regular compensatory behaviors.{{cite web|url=https://www.statpearls.com/point-of-care/35385|title=Binge Eating Disorder|publisher=StatPearls|accessdate=June 25, 2026}}

==Avoidant/restrictive food intake disorder==
'''[[Avoidant/restrictive food intake disorder]]''' or '''ARFID''' is an eating disorder involving avoidant or restrictive eating that leads to weight loss, nutritional deficiency, dependence on supplements or tube feeding, or psychosocial impairment. Unlike anorexia nervosa, ARFID is not driven by fear of fatness or body image distortion.

ARFID may involve:

{{div col|colwidth=15em}}
* Low appetite
* Sensory sensitivity to food texture, smell, or taste
* Fear of choking
* Fear of vomiting
* Fear of allergic reaction
* Very limited food variety
* Failure to gain expected weight in children
* Nutritional deficiency
* Social impairment
{{div col end}}

StatPearls describes ARFID as significant limitations in food intake leading to malnutrition, weight loss, or nutritional deficiency without the body image disturbance typically seen in anorexia nervosa or bulimia nervosa.{{cite web|url=https://www.statpearls.com/point-of-care/164812|title=Avoidant Restrictive Food Intake Disorder|publisher=StatPearls|accessdate=June 25, 2026}}

==Pica==
'''[[Pica]]''' is persistent eating of non-food, non-nutritive substances such as clay, soil, chalk, paper, ice, paint chips, laundry starch, hair, or soap. It may occur in children, pregnancy, iron deficiency, developmental disability, autism spectrum disorder, or psychiatric conditions.

Complications may include:

{{div col|colwidth=15em}}
* Iron deficiency
* Lead poisoning
* Intestinal obstruction
* Dental injury
* Infection
* Malnutrition
* Toxic exposure
{{div col end}}

==Rumination disorder==
'''[[Rumination disorder]]''' involves repeated regurgitation of food after eating. Regurgitated food may be rechewed, reswallowed, or spit out. It is not explained by vomiting from a gastrointestinal illness.

Possible consequences include:

{{div col|colwidth=15em}}
* Weight loss
* Malnutrition
* Bad breath
* Dental erosion
* Social embarrassment
* Esophagitis
* Feeding difficulty in children
{{div col end}}

==Other specified feeding or eating disorder==
'''[[Other specified feeding or eating disorder]]''' or '''OSFED''' includes clinically significant eating disorder symptoms that do not meet full criteria for another diagnosis. OSFED can be serious and medically dangerous.

Examples include:

{{div col|colwidth=15em}}
* [[Atypical anorexia nervosa]]
* [[Purging disorder]]
* [[Night eating syndrome]]
* Subthreshold [[bulimia nervosa]]
* Subthreshold [[binge eating disorder]]
* Other clinically significant disordered eating
{{div col end}}

==Unspecified feeding or eating disorder==
'''[[Unspecified feeding or eating disorder]]''' or '''UFED''' is used when symptoms cause distress or impairment but do not clearly fit another category or when there is insufficient information to make a more specific diagnosis.

==Orthorexia nervosa==
'''[[Orthorexia nervosa]]''' is an unhealthy obsession with eating only foods considered “clean,” “pure,” “healthy,” or “safe.” It is not a formal DSM-5-TR diagnosis, but it can cause significant impairment and may overlap with anorexia nervosa, obsessive-compulsive traits, anxiety, or excessive dieting.

Possible signs include:

{{div col|colwidth=15em}}
* Rigid food rules
* Fear of “unclean” foods
* Anxiety when preferred foods are unavailable
* Social isolation
* Nutritional deficiency
* Moral judgment around food
* Excessive time spent researching food
* Restriction that becomes unhealthy
{{div col end}}

==Night eating syndrome==
'''[[Night eating syndrome]]''' involves recurrent evening or nighttime eating, often with insomnia, morning lack of appetite, and distress. It may overlap with obesity, depression, anxiety, sleep disorders, and circadian rhythm disruption.

Common features include:

{{div col|colwidth=15em}}
* Eating a large proportion of calories after dinner
* Waking from sleep to eat
* Difficulty sleeping unless eating
* Morning lack of appetite
* Guilt or distress
* Weight gain
* Insomnia
{{div col end}}

==Purging disorder==
'''[[Purging disorder]]''' involves recurrent purging behavior to influence weight or shape without objectively large binge eating episodes. Purging may include vomiting, laxatives, diuretics, enemas, fasting, or excessive exercise.

Risks include:

{{div col|colwidth=15em}}
* Electrolyte imbalance
* Irregular heartbeat
* Dental erosion
* Esophageal injury
* Dehydration
* Kidney injury
* Laxative dependence
{{div col end}}

==Diabulimia==
'''[[Diabulimia]]''' is an informal term for insulin restriction or omission in people with [[type 1 diabetes]] to lose weight. It is not a formal DSM diagnosis, but it is medically dangerous.

Potential complications include:

{{div col|colwidth=15em}}
* Severe hyperglycemia
* Diabetic ketoacidosis
* Dehydration
* Neuropathy
* Retinopathy
* Kidney disease
* Hospitalization
* Death
{{div col end}}

Patients with suspected insulin omission require urgent diabetes and mental health care.

==Muscle dysmorphia and compulsive exercise==
'''[[Muscle dysmorphia]]''' is a body image disorder in which a person becomes preoccupied with being insufficiently muscular. It may involve excessive exercise, rigid dieting, supplement misuse, anabolic steroid use, and distress about body appearance.

'''[[Compulsive exercise]]''' can occur in anorexia nervosa, bulimia nervosa, orthorexia, and other eating disorders. Exercise becomes harmful when it is driven by fear, guilt, punishment, injury, or inability to rest.

==Disordered eating versus eating disorder==
'''[[Disordered eating]]''' refers to unhealthy eating behaviors that may not meet full diagnostic criteria for an eating disorder but still cause harm. Examples include chronic dieting, meal skipping, fasting-binge cycles, guilt after eating, emotional overeating, compulsive calorie tracking, or rigid food rules.

Disordered eating can progress to an eating disorder, especially when combined with body dissatisfaction, weight stigma, trauma, depression, anxiety, or repeated dieting.

==Risk factors==
Risk factors for eating disorders include:

{{div col|colwidth=15em}}
* Family history of eating disorders
* Family history of depression or anxiety
* Dieting

{{div col end}}

==Diagnosis==
Eating disorders are diagnosed through clinical evaluation. A medical clinician, mental health professional, psychiatrist, psychologist, or eating-disorder specialist may evaluate symptoms, behaviors, medical stability, and DSM-5-TR diagnostic criteria.

Assessment may include:

{{div col|colwidth=15em}}
* Eating history
* Weight history

{{div col end}}

==Nutritional rehabilitation==
Nutrition treatment focuses on restoring safe eating patterns, correcting deficiencies, reducing food fear, stabilizing weight, and normalizing hunger and fullness signals.

Goals may include:

{{div col|colwidth=15em}}
* Regular meals
* Adequate protein
* Adequate calories
* Electrolyte correction
* Avoiding binge-restrict cycles
* Reducing food rules
* Reintroducing feared foods

* SSRIs for depression or anxiety
* Topiramate in selected binge-eating cases, with caution
* Treatment of ADHD when appropriate
* Treatment of sleep disorders when appropriate
* Diabetes medication adjustment when needed
{{div col end}}

Medication should not replace psychotherapy and nutrition treatment.

==Eating disorders and obesity==
Eating disorders can occur at any body weight. Patients with obesity may have [[binge eating disorder]], night eating, emotional eating, trauma-related eating, weight cycling, or disordered dieting. Treating obesity without screening for eating disorders can worsen restriction-binge cycles, shame, and regain.

Important principles include:

{{div col|colwidth=15em}}
* Avoid shame-based care
* Avoid crash diets
* Screen for binge eating before restrictive diets
* Screen for purging before medication use
* Focus on metabolic health
* Address sleep apnea
* Address insulin resistance
* Preserve lean mass
* Use structured follow-up
* Refer severe cases to specialists
{{div col end}}

==Binge eating disorder and medical weight loss==
Binge eating disorder is one of the eating disorders most relevant to medical weight loss clinics. Patients may seek weight loss care because of obesity, but the underlying driver may be binge eating, night eating, emotional eating, sleep deprivation, depression, trauma, or severe insulin resistance.

A comprehensive program may help by combining:

{{div col|colwidth=15em}}
* Medical assessment
* Binge eating screening
* Nutrition counseling
* Protein planning
* Structured meals
* Sleep apnea screening
* Medication review
* Behavioral support
* GLP-1 evaluation when appropriate
* Mental health referral
* Long-term maintenance planning
{{div col end}}

==Eating disorders and sleep==
Sleep problems can worsen eating patterns. [[Sleep apnea]], [[insomnia]], delayed sleep timing, shift work, and short sleep can increase hunger, cravings, fatigue, and nighttime eating.

Sleep-related contributors include:

{{div col|colwidth=15em}}
* [[Obstructive sleep apnea]]
* [[Insomnia]]
* [[Night eating syndrome]]
* [[Shift work sleep disorder]]
* [[Delayed sleep phase syndrome]]
* Sleep deprivation
* Daytime fatigue
{{div col end}}

==How W8MD can help diagnose eating disorders==
[[W8MD Weight Loss, Sleep and MedSpa]] physicians can help identify eating disorders and related eating problems during medical weight-loss and sleep evaluations.

W8MD may help with:

{{div col|colwidth=15em}}
* Screening for [[binge eating disorder]]
* Screening for [[night eating syndrome]]
* Screening for emotional eating
* Screening for unsafe restriction
* Screening for purging behaviors
* Weight history review
* Diet history review
* Medication review
* Medical complication assessment
* Laboratory testing when appropriate
* Sleep apnea screening
* Mental health referral when needed
* Eating-disorder specialist referral when needed
{{div col end}}

==How W8MD can help treat common eating-related problems==
W8MD can help treat many common eating-related and weight-related problems, especially when they overlap with obesity, insulin resistance, sleep apnea, and metabolic syndrome.

W8MD may help patients with:

{{div col|colwidth=15em}}
* [[Binge eating disorder]]

{{div col end}}

W8MD treatment may include:

{{div col|colwidth=15em}}
* Physician-supervised [[medical weight loss]]
* Nonjudgmental eating assessment
* Structured meal planning
* [[Nutrition counseling]]
* [[Meal replacements]] when appropriate
* [[Low-carbohydrate diet]] planning when appropriate
* Protein planning
* [[GLP-1 weight loss]] evaluation when appropriate
* [[Semaglutide]] or [[tirzepatide]] evaluation when appropriate
* Sleep apnea testing
* [[CPAP]] support
* Mental health referral
* Coordination with therapists and dietitians
* Long-term maintenance
{{div col end}}

==When W8MD should refer to specialty eating-disorder care==
Some eating disorders require urgent or specialized treatment beyond a standard weight-loss clinic.

Referral or urgent care is needed for:

{{div col|colwidth=15em}}
* Severe [[anorexia nervosa]]
* Medically unstable weight loss
* Low heart rate
* Fainting
* Electrolyte abnormalities
* Frequent vomiting
* Laxative or diuretic abuse
* Diabulimia
* Suicidal thoughts
* Severe depression
* Pregnancy with eating disorder
* Adolescents with rapid weight loss
* Failure to eat enough to maintain health
* Need for inpatient or residential care
{{div col end}}

==W8MD and safe weight management in patients with eating disorder history==
Patients with a past eating disorder may still need medical treatment for obesity, diabetes, sleep apnea, or insulin resistance. W8MD can help by avoiding unsafe restriction and using careful monitoring.

Principles include:

{{div col|colwidth=15em}}
* Avoid crash diets
* Avoid shame-based weigh-ins
* Avoid extreme calorie restriction unless medically supervised and appropriate
* Screen for relapse symptoms
* Focus on protein, sleep, and metabolic health
* Include mental health support
* Monitor purging or binge urges
* Use GLP-1 medications cautiously when appropriate
* Coordinate with therapist or dietitian
{{div col end}}

==Frequently asked questions==
===What are eating disorders?===
Eating disorders are serious mental and medical conditions involving abnormal eating behaviors, distressing thoughts about food or body shape, and physical or psychological harm.

===What are the main types of eating disorders?===
Major eating disorders include anorexia nervosa, bulimia nervosa, binge eating disorder, avoidant/restrictive food intake disorder, pica, rumination disorder, other specified feeding or eating disorder, and unspecified feeding or eating disorder.

===Can eating disorders occur in people with obesity?===
Yes. Eating disorders can occur at any weight. Binge eating disorder, night eating syndrome, bulimia nervosa, purging disorder, and atypical anorexia can occur in people with overweight or obesity.

===What is the most common eating disorder?===
Binge eating disorder is commonly reported as one of the most common eating disorders, especially in weight management and obesity medicine settings.

===Can W8MD diagnose eating disorders?===
W8MD physicians can screen for and diagnose many common eating-related problems and identify when specialty mental health or eating-disorder care is needed.

===Can W8MD treat eating disorders?===
W8MD can help treat many common eating-related conditions such as binge eating disorder, night eating syndrome, emotional eating, weight cycling, and obesity-related disordered eating, especially when combined with medical weight loss, sleep care, and referrals. Severe anorexia, severe bulimia, medical instability, or suicidality require urgent specialty care.

===Is binge eating disorder treated differently from obesity?===
Yes. Binge eating disorder requires attention to loss of control eating, emotional triggers, shame, depression, anxiety, sleep, and behavioral treatment. Weight loss alone is not enough.

===Can GLP-1 medications help binge eating?===
GLP-1 medications may reduce appetite and cravings in some patients, but they are not a substitute for eating-disorder evaluation and therapy. They should be used carefully and medically supervised.
