Enhanced cognitive behavioral therapy (CBT-E) is a structured, individualized psychotherapy designed to treat the psychological and behavioral processes that maintain many eating disorders. The approach is called transdiagnostic because it can be adapted across several diagnoses, especially when restriction, binge eating, compensatory behaviors, rigid dietary rules, and excessive concern about eating, shape, or weight are involved. It is one of the recognized specialist approaches for adults with eating disorders, with evidence and indications that vary by diagnosis, age, medical condition, and treatment setting. The American Psychiatric Association guideline and NICE guidance provide diagnosis-specific recommendations.
This guide explains how CBT-E works, its four stages, focused and broad versions, its evidence for bulimia nervosa, binge eating disorder, anorexia nervosa and related diagnoses, the role of medical care, and what to expect when choosing a clinician. For a comparison of the full range of treatments, see Eating Disorder Treatment: Evidence-Based Therapies and Care.
What Is Enhanced Cognitive Behavioral Therapy (CBT-E)?
CBT-E stands for enhanced cognitive behavioral therapy. Developed by Christopher Fairburn and colleagues, it is a specialized form of CBT that uses an individualized formulation of the eating disorder rather than treating each diagnostic label as a completely separate problem. The therapist and patient identify current maintaining processes, develop a treatment plan, test changes in daily life, and review the results. The word enhanced refers to the expanded and formalized approach; it does not mean that CBT-E is always more effective than every other psychotherapy.
CBT-E is a therapeutic protocol, rather than a clinical diagnosis, subtype, or screening questionnaire. It is frequently described alongside eating-disorder-focused cognitive behavioral therapy (CBT-ED), the broader family of specialized CBT interventions referenced by clinical guidelines. CBT-E belongs to that family but has its own manualized transdiagnostic model. A therapist offering general CBT may not necessarily be trained in CBT-E or in managing medically complex eating disorders. The original transdiagnostic study and APA guideline outline its clinical foundations.
The treatment aims to improve eating behavior, reduce harmful maintaining patterns and eating-disorder psychopathology, and support recovery of physical, psychological, and social functioning. Where undernutrition or medical instability is present, appropriate nutritional rehabilitation and medical monitoring form essential parts of care. Effective treatment attends to both the patient's experiences and the physical consequences of the disorder.
How CBT-E Explains and Treats Eating Disorder Patterns
The organizing clinical idea is that many eating disorders persist through interacting patterns of behavior, thought, emotion, and reinforcement. Severe dietary rules may contribute to irregular eating and preoccupation; departures from those rules can provoke distress, further restraint, binge episodes, or compensatory responses. Short-term relief from distress may reinforce behaviors that worsen health and daily functioning. This is a possible maintenance cycle, not an assumption about every person.
For some patients, self-worth becomes unusually dependent on perceived control over food, weight, or shape. Other patients experience binge episodes primarily in a context of emotional distress, disrupted eating patterns, or other maintaining processes. A genuine assessment identifies what is active in the individual case. The treatment does not presume that all eating disorders arise from one cause or that people with the same diagnostic label have identical histories.
Collaborative case formulation
The therapist develops a practical working account of the person's difficulties, based on clinical interviews, current behaviors, symptom history, emotions, interpersonal situations, nutritional status, and health risk. This formulation is revised as treatment proceeds. It guides the selection of interventions and helps both parties understand why a particular change is being attempted.
CBT-E often examines restrictive rules, avoidance, food-related anxiety, body checking or avoidance where relevant, compensation after eating, and all-or-nothing interpretations. The therapist may also consider perfectionism, chronically low self-esteem, or interpersonal difficulties if these clearly maintain the disorder. Such factors are assessed instead of being attributed to all patients. The developers' explanation of focused and broad CBT-E distinguishes these options.
Behavioral and cognitive change
Therapeutic methods may include supportive self-monitoring, regular and adequately nourishing eating, cognitive restructuring, behavioral experiments, gradual reduction of avoidance, examination of rigid rules, and work on handling difficult emotions. A patient learns to recognize patterns in real contexts and to evaluate whether changes reduce symptoms and restore participation in everyday life.
Self-monitoring is a way of understanding patterns with a clinician, rather than a competition, a calorie target, or an invitation to compulsive tracking. Behavioral experiments are tailored to the person's health and readiness. For individuals who are malnourished, nutritional support and medical safety are prerequisites for certain interventions. No psychological exercise should replace urgent medical care.
The Four Stages of CBT-E
A standard specialist outpatient course for many adults who do not require extensive weight restoration is often described as approximately 20 sessions over 20 weeks. Longer treatment, commonly approximately 40 sessions over 40 weeks, may be appropriate when significant nutritional rehabilitation is required. These are typical protocols, not automatic decisions based on BMI. Duration and intensity depend on clinical need, safety, response, and setting. See APA clinical guidance, NICE NG69, and the CBT-E model description.
Stage 1: Engagement and early change
The first stage develops a shared understanding of the eating disorder and establishes a collaborative working relationship. The patient and clinician identify what has been happening, what is maintaining symptoms, and what changes are most urgently needed. They begin using supportive monitoring to learn about the timing and context of eating behaviors and distress. The clinician may work toward a more regular pattern of eating and address immediate obstacles to progress.
Appointments may initially be more frequent. Individualized psychoeducation explains relevant psychological and physical mechanisms and gives context for interventions. Medical concerns that emerge must be evaluated by the appropriate team. If a person is physically unstable, urgent stabilization takes priority over following the usual outpatient sequence.
Stage 2: Review and refinement
A brief review stage considers progress, remaining symptoms, barriers to change, and the accuracy of the original formulation. The patient and therapist agree on the main targets for the next phase. They may decide whether focused CBT-E is sufficient or whether particular maintaining problems require the broad form.
A clinical review can also reveal a need to clarify diagnosis, address depression or anxiety, involve other professionals, or increase the level of care. Treatment is responsive to what the evidence in the individual case shows, rather than a fixed series of worksheets that must be completed regardless of outcome.
Stage 3: Addressing maintaining processes
The main working stage targets the difficulties identified in the formulation. For some patients, this includes reducing dietary rigidity, examining fears associated with eating, and decreasing the influence of shape or weight on self-evaluation. For others it focuses more on recurrent loss-of-control eating, emotional cues, interpersonal situations, or persistent avoidance.
Cognitive work explores the consequences of beliefs and their alternatives. Behavioral work creates supported opportunities to test a different response in real life. The aim is more flexible, sustainable functioning and lower symptom burden. The specific tasks differ across diagnoses; a protocol used for bulimia must not be transferred uncritically to ARFID or a medically unstable person with anorexia.
Stage 4: Consolidation and relapse prevention
The concluding stage examines improvements, remaining vulnerabilities, and how to maintain change after formal treatment. The patient develops an individualized plan for responding early to a return of restrictive rules, binge eating, compensatory behavior, or distress. Meetings may become less frequent and a later review may be planned.
A setback is information that informs clinical reassessment. It can mean that an earlier maintaining process has returned, a new stressor requires attention, or nutritional and medical needs have changed. A relapse plan identifies how to regain support and when urgent medical reassessment is necessary.
Focused CBT-E Versus Broad CBT-E
Focused CBT-E concentrates on the core eating-disorder psychopathology and its maintaining processes. Broad CBT-E includes additional work on pronounced clinical perfectionism, low self-esteem, or interpersonal difficulties when these problems are actively maintaining the eating disorder. Mood intolerance has also been discussed within foundational formulations of the broad approach.
The broader form is selected for a reason: extra modules should address demonstrable barriers rather than be added automatically because the patient has several diagnoses or personality traits. A 2009 randomized trial comparing the two forms reported substantial, generally comparable benefits in the study population, and the model developers recommend focused CBT-E as the usual starting version. Co-occurring psychiatric conditions may need additional interventions coordinated with eating-disorder care.
Which Eating Disorders Can CBT-E Treat?
CBT-E's transdiagnostic design makes it useful in multiple presentations, but indications and comparative evidence differ. Established recommendations distinguish anorexia nervosa, bulimia nervosa, binge eating disorder, adolescent presentations, and feeding disorders with different maintaining mechanisms. APA and NICE should guide choices for specific diagnoses.
Bulimia nervosa
Eating-disorder-focused CBT is a central evidence-supported psychotherapy for adults with bulimia nervosa. Its goals include decreasing binge episodes and compensatory behaviors, developing a more consistent eating pattern, and addressing rigid beliefs and distress that maintain the condition. CBT-E is one structured way of delivering specialized CBT.
NICE recommends considering individual CBT-ED when bulimia-focused guided self-help is unacceptable, contraindicated, or ineffective following an initial trial. APA also recommends eating-disorder-focused CBT for adults with bulimia nervosa and discusses additional medication treatment. Medications require professional prescribing and do not replace medical evaluation of complications associated with purging. NICE recommendations; APA guideline.
Binge eating disorder
For BED, specialized CBT can help reduce recurrent binge eating, loss of control, and associated distress. CBT-E may be relevant when the individualized formulation fits the presentation, while interpersonal psychotherapy and other CBT-ED formats are also supported. NICE generally begins with BED-focused guided self-help and recommends group or individual CBT-ED depending on response, availability, and patient choice.
BED psychotherapy is not a weight-loss program. NICE specifically notes that weight loss is not the goal of psychological treatment and cautions against dieting during treatment because it can provoke further binge eating. A patient's body size does not establish whether BED is present, how severe it is, or whether treatment has worked. NICE NG69.
Anorexia nervosa in adults
For adults with anorexia nervosa, specialized CBT-ED, MANTRA, and specialist supportive clinical management are options discussed in clinical guidance. CBT-E has been adapted for restrictive and underweight presentations, generally with a longer course. Adequate nourishment, medically appropriate weight restoration, and close assessment of physical health are necessary components of treatment when the person is malnourished.
CBT-E has evidence for clinical benefit in some adult anorexia patients, but it has not demonstrated universal superiority to active alternatives. A 2025 meta-analysis of individual CBT found a limited number of anorexia-specific trials and no clear advantage over active treatments. Treatment should be selected through shared clinical decision-making that takes account of medical severity, history, access, and response. NICE adult anorexia recommendations.
Atypical anorexia and OSFED
Atypical anorexia is a presentation classified within other specified feeding or eating disorder (OSFED): significant anorexia-like symptoms may be present without the low-weight criterion. Severe medical and psychological complications can arise even at weights often considered typical or higher, especially after rapid or substantial weight loss. Medical assessment must consider behavior, changes in nutritional status, cardiovascular health, and other findings. The SAHM clinical position paper documents medical risk beyond low BMI.
CBT-E may be adapted for clinically appropriate OSFED presentations, including cases with rigid restriction, binge episodes, or purging. Specific formulations and medical monitoring remain essential. UFED is an unspecified diagnostic category used in particular assessment circumstances; it is not a separate CBT-E treatment program. Differences between purging disorder, night eating syndrome, bulimia nervosa, and other diagnoses matter for assessment and selection of care.
Adolescents and family-based treatment
CBT-E has adolescent adaptations, but findings from adult outpatient studies do not establish identical outcomes for minors. In adolescent anorexia, family-based treatment (FBT) or eating-disorder-focused family therapy is a major recommended option when caregivers can participate. The family helps support eating and medical recovery while professionals coordinate assessment and care.
A 2025 systematic review and meta-analysis of adolescent family therapy found stronger end-of-treatment weight gain relative to individual psychotherapy, although many other comparisons were inconclusive. A review of routine clinical care found favorable outcomes with family therapy and CBT, with considerable risk of bias. Age, development, available support, and patient circumstances determine whether an individual CBT-based approach should be considered.
ARFID and other feeding disorders
Avoidant/restrictive food intake disorder (ARFID) can involve sensory sensitivity, low interest in eating, or fear of consequences such as choking or vomiting. The characteristic preoccupation with shape and weight found in many other eating disorders is not required. Standard CBT-E's most familiar maintaining-process model therefore may not match the primary problem. CBT for ARFID (CBT-AR) is a separate adapted approach with its own evidence base.
An early CBT-AR feasibility and proof-of-concept study reported promising improvement in children and adolescents but emphasized the need for randomized trials. Pica and rumination disorder also need distinct diagnostic and treatment pathways, often incorporating behavioral and medical interventions. Eating-related avoidance requires assessment for swallowing conditions, gastrointestinal illness, ARFID, and specific phobias. See Choking Phobia: Fear of Choking, Eating Avoidance, and Differential Diagnosis.
Orthorexia and emerging language
Orthorexia is a popular research and clinical discussion term for problematic preoccupation with supposedly healthy or pure eating. It is not a standalone diagnosis in DSM-5-TR or ICD-11. Clinicians assess actual behavior, impairment, nutritional problems, and whether an established eating disorder explains the presentation. Claims that standard CBT-E is proven for a distinct orthorexia diagnosis go beyond existing evidence.
What Does Scientific Evidence Say About CBT-E?
Evidence must be interpreted with its population, comparison, length of follow-up, and definition of improvement. Trial results should not be converted into a personalized recovery forecast. Direct CBT-E randomized trials and broader reviews of eating-disorder-focused CBT address overlapping but different questions.
The original randomized transdiagnostic trial
A two-site randomized trial published in 2009 enrolled 154 outpatients with eating disorders who were not markedly underweight. It compared focused and broad CBT-E, with a waiting-list period in the comparison design, and observed substantial improvement over the course of treatment, broadly maintained at follow-up. At 60-week follow-up, 51.3% of the sample had eating disorder features within the study's defined range near the community distribution. That finding illustrates clinical potential within the study sample, not guaranteed remission or efficacy for severely malnourished patients. Fairburn et al., 2009.
CBT-E versus interpersonal psychotherapy
A 2015 randomized trial studied 130 participants with different eating disorder diagnoses and compared CBT-E with interpersonal psychotherapy. Both treatments involved 20 sessions across 20 weeks. At treatment end, 65.5% of CBT-E participants met the trial's remission definition, compared with 33.3% of those receiving interpersonal psychotherapy. At follow-up, the respective figures were 69.4% and 49.0%. These percentages are specific to this trial's patients, assessment criteria, and follow-up period. Fairburn et al., 2015.
The findings support CBT-E as an effective option and suggest a faster response in that comparison, while IPT remains a legitimate evidence-based approach in appropriate circumstances. The study did not establish that CBT-E is superior for all eating disorder diagnoses, at every degree of medical severity, or in all age groups.
CBT-E versus treatment as usual
A randomized study of 143 adults found an early advantage for CBT-E over treatment as usual in reducing eating disorder psychopathology, along with a higher recovery rate at 20 weeks under the study's chosen definition. At 80 weeks, the between-group differences in recovery were no longer statistically significant. CBT-E was shorter and less intensive in this study. The distinction between early improvement and sustained superiority is essential for realistic treatment planning. 2020 randomized trial.
The 2025 meta-analysis: evidence and limitations
A meta-analysis published in 2025 combined 42 randomized trials of individual CBT interventions for eating disorders. CBT showed benefits over waiting-list controls for multiple outcomes in bulimia nervosa, BED, and mixed diagnostic populations. Compared with a heterogeneous collection of active treatments, CBT was not consistently more effective. The researchers identified substantial variability, a high risk of bias in many studies, and relatively few anorexia-specific trials. Bruns, Meier, and Jansen, 2025.
This is a review of CBT across formats, not a meta-analysis exclusively of CBT-E. It supports the broader treatment family while requiring caution about claiming an exact CBT-E effect. Future trials should better compare named therapies, report durable recovery consistently, and include diverse patient populations and medically complex cases.
How outcomes are measured
Clinical research may report reductions in eating disorder thoughts, binge episodes or compensatory behaviors, improvements in functioning, weight restoration when clinically indicated, or remission based on a particular instrument or diagnostic definition. A treatment can improve one domain without resolving every health risk. Completion rates, missing follow-up data, and the choice of remission threshold all influence reported success.
A self-report questionnaire can track symptoms or screen for further assessment, but it does not diagnose an eating disorder by itself. Proper evaluation combines interviews, history, clinical judgment, and medical examination when indicated. Patients should be able to understand what their treatment team is measuring and why.
CBT-E Compared With Other Eating Disorder Treatments
General CBT is a broad psychotherapy family; CBT-E is a specialized eating-disorder treatment with structured stages and an individualized transdiagnostic formulation. General anxiety or depression CBT may share cognitive and behavioral methods without addressing the distinctive medical and nutritional needs of eating disorder patients.
FBT places caregivers in a central therapeutic role, often with an adolescent whose nutrition and safety require close support. CBT-E generally organizes treatment around an individual patient's collaborative formulation, although family participation can be incorporated. IPT focuses on interpersonal patterns and has clinical evidence, particularly in BED. MANTRA and specialist supportive clinical management are recognized options for adult anorexia. Guided self-help and group CBT-ED can be appropriate for selected bulimia or BED presentations. NICE NG69 provides clinical distinctions among these treatments.
Medications may have a role for some eating disorders or co-occurring conditions, but they are not interchangeable with CBT-E. Their indications differ by diagnosis and require a prescriber. An automated chatbot or a general digital mental health application also should not be treated as the equivalent of trained clinician-delivered CBT-E solely because it contains CBT-style exercises.
Medical Risks and the Need for Coordinated Care
Eating disorders can cause cardiovascular complications, disturbances in electrolytes and hydration, gastrointestinal symptoms, nutritional deficiencies, endocrine changes, and other serious harm. Risk is influenced by restriction, purging, rapid changes in weight, and current physical findings. A person can be medically unstable at a wide range of body sizes. Clinical assessment considers vital signs, symptom history, physical examination, weight and growth trajectory when relevant, and laboratory or cardiac investigations where indicated.
The Society for Adolescent Health and Medicine emphasizes that atypical anorexia and ARFID can produce serious complications and that hospitalization decisions are based on comprehensive assessment, not body mass alone. NICE likewise requires attention to physical health throughout eating disorder treatment.
Outpatient CBT-E may be appropriate for many clinically stable people, but severe restriction, acute deterioration, dangerous compensatory behaviors, serious medical abnormalities, or inadequate outpatient support can require intensive or inpatient care. Nutritional rehabilitation for significantly malnourished patients should be coordinated by qualified professionals with appropriate monitoring. Psychological recovery work continues alongside physical recovery, with the intensity of care adapted to risk.
Fainting, chest pain, marked weakness, confusion, palpitations, or suspected serious dehydration require prompt medical assessment, and some presentations require emergency services. This article cannot establish whether an individual is medically stable.
What Happens Before Starting CBT-E?
A specialist assessment explores the nature and course of eating problems, nutritional status, restriction and avoidance, loss-of-control episodes, compensatory behaviors, body-image concerns when relevant, psychological distress, physical symptoms, previous treatment, and current functional impairment. It also examines whether depression, anxiety, obsessive-compulsive symptoms, trauma-related difficulties, substance use, or neurodevelopmental characteristics influence care.
Differential diagnosis may include anorexia nervosa, atypical anorexia, bulimia nervosa, BED, ARFID, OSFED, UFED, pica, rumination disorder, gastrointestinal or swallowing problems, specific phobias, and other relevant medical or psychiatric conditions. A symptom such as food avoidance or episodic overeating has different meanings in different contexts. The purpose of an assessment is to choose an appropriate, safe pathway rather than merely attach a label.
A patient and clinician should discuss treatment goals, medical oversight, what monitoring involves, privacy, how progress will be reviewed, and when an additional or higher level of care would be considered. Treatment plans should accommodate development, accessibility, cultural circumstances, and reasonable patient preferences.
Choosing a CBT-E Therapist
A competent provider should understand eating disorder diagnosis and physical risk as well as the CBT-E protocol. Useful questions concern the clinician's formal experience with CBT-E, which diagnoses and ages they treat, how they coordinate with physicians and dietitians, whether progress is reviewed systematically, and how treatment changes when someone is not improving.
Treatment is a collaborative process. The therapist should explain the rationale for exercises, how risks are assessed, and how consent is maintained. Adolescents and patients with significant medical complexity may need a coordinated multidisciplinary team and, where appropriate, active caregiver involvement.
If CBT-E is not accessible, suitable evidence-based alternatives may still be available. Waiting for a specifically branded protocol should not delay medical assessment or necessary eating disorder care. The most appropriate option depends on diagnosis, age, clinical severity, and local specialist resources.
Recovery, Follow-Up, and Relapse Prevention
Meaningful progress can include safer and more adequate nutrition, fewer harmful eating disorder behaviors, reduced distress and preoccupation, improved physical health, stronger participation in relationships and daily life, and a more flexible relationship with food and the body. For restrictive illnesses, medical recovery and adequate nutrition are essential outcomes. Clinicians should agree with patients on relevant indicators without turning measurements into a source of shame or obsessive checking.
Recovery may be gradual, and a plateau may signal a need to adjust the formulation, involve another discipline, treat a comorbid problem, or increase the level of care. The aim of relapse prevention is to make support accessible when new difficulties emerge. No fixed session count can guarantee recovery.
Appearance-focused online environments can interact with a person's concerns in complex ways, but they represent a separate research question from the efficacy of CBT-E. For that topic, see Social Media and Body Image.
Frequently Asked Questions
Is CBT-E the same as ordinary CBT?
CBT-E is a manualized, eating-disorder-focused version of CBT. It shares cognitive and behavioral principles with other CBT approaches while using specialized formulations and procedures. Treating an eating disorder safely may also require nutrition and medical specialists.
Is CBT-E evidence-based?
Yes, direct randomized trials support CBT-E for particular adult outpatient populations, and broader studies support specialized CBT for certain eating disorder diagnoses. The strength of evidence differs across conditions. The 2025 CBT meta-analysis found benefits over waiting lists without consistent superiority over active therapies.
How many sessions are needed?
Common protocols involve around 20 sessions over 20 weeks for many adults not requiring substantial weight restoration and longer treatment, often around 40 sessions, when more extensive restoration is required. Actual duration follows clinical assessment and response rather than body size alone. APA guidance.
Is CBT-E suitable for anorexia nervosa?
It can be a specialist psychological treatment for adults with anorexia, alongside appropriate nutrition and medical care. Other recognized therapies are available, and comparative evidence does not establish universal superiority. For adolescents, family-based treatment is often the preferred first-line option. NICE; APA.
Is CBT-E suitable for bulimia nervosa?
Eating-disorder-focused CBT is a major recommended treatment for adults with bulimia, and CBT-E is a specialized form. Clinical care must also assess complications associated with compensatory behaviors. APA.
Does CBT-E help binge eating disorder?
CBT-based interventions can help reduce binge eating and related distress. The psychological treatment's goal is not weight loss. Guided self-help, group or individual CBT-ED, and IPT are among the options discussed in guidelines. NICE.
Does CBT-E require weight gain?
For individuals whose health is compromised by undernutrition, adequate nutritional rehabilitation and medically appropriate restoration may be necessary. In other diagnoses, goals differ, and psychotherapy for BED is not designed as a weight-loss intervention. The medical plan is individualized, not dictated by an article. NICE.
Can CBT-E treat ARFID?
ARFID often has different maintaining mechanisms. CBT-AR is a related but distinct treatment designed for that disorder. Its early studies are promising but should not be conflated with evidence for standard CBT-E. Thomas et al., 2020.
Can children and adolescents receive CBT-E?
There are adolescent adaptations, but selecting treatment requires age-specific evidence and attention to caregiver involvement, growth, medical health, and development. Family-based treatment is often prioritized for adolescent anorexia. Austin et al., 2025.
Is online or self-guided CBT-E equivalent to therapist-delivered treatment?
Evidence from trained clinician-delivered CBT-E cannot be assumed to prove effectiveness of an app, chatbot, or unguided course. Guided self-help has a role in selected eating disorder presentations, but it is a separately studied intervention and requires appropriate screening and escalation pathways.
Does one trial show that CBT-E always works better than IPT?
No. A 2015 randomized trial favored CBT-E in its sample, but the results depend on eligibility, diagnostic composition, the trial's remission definition, and follow-up. They are not universal guarantees.
How quickly should symptoms improve?
Some patients make early gains, while others need longer treatment. Progress is evaluated in behavior, distress, functioning, nutritional and medical health, and durability of improvement. A 2020 trial found an early advantage that was no longer statistically significant at longer follow-up.
What if treatment is not helping?
Review the assessment and formulation, check nutritional and medical needs, evaluate comorbidity, and discuss a different treatment or higher level of care. Deterioration or medical instability should prompt timely reassessment rather than continued routine outpatient sessions without adjustment.
Can a serious eating disorder occur at a higher body weight?
Yes. Serious malnutrition and medical instability can occur without a low BMI. Rate and magnitude of weight change, behaviors, growth history when relevant, clinical findings, and function all matter. SAHM.
Is orthorexia an official diagnosis treated by CBT-E?
Orthorexia is not a standalone DSM-5-TR or ICD-11 diagnosis. A clinician should evaluate the actual symptoms and determine whether an established diagnosis applies. Evidence is insufficient to assert that CBT-E is proven for a separate orthorexia diagnosis.
When should someone seek emergency help?
Chest pain, fainting, confusion, severe weakness, palpitations, marked dehydration, or other signs of acute instability warrant prompt medical assessment, with emergency services when indicated. Eating disorder treatment must address physical risk as well as psychological distress.
