Key facts
Eating disorders at a glance.
The essentials, in plain English — the main types, how common they are, and how they’re treated in the UK today.
-
What they are
Serious mental-health conditions — anorexia nervosa, bulimia nervosa, binge-eating disorder, ARFID and OSFED — that affect body, mind and family.
-
How common
Around 1.25 million people in the UK live with an eating disorder.
-
Mortality
Anorexia nervosa has the highest mortality of any mental illness — early treatment saves lives.
-
Refeeding risk
Refeeding syndrome is a real, potentially fatal risk — electrolyte shifts must be managed by specialists.
-
Referral
Early referral to a specialist eating-disorder service (SEDIS) is what changes trajectories.
-
Family therapy
Maudsley family-based treatment (FBT) is first-line for adolescents with anorexia.
Why this guide matters
Serious — and treatable — with the right team.
Eating disorders are life-changing conditions, but recovery is possible. The three points below shape everything else on this page.
-
Early referral changes outcomes
The longer an eating disorder is untreated, the harder it becomes to treat. Specialist input early matters.
-
It’s a family condition
Especially for adolescents, family are part of the treatment — not a bystander to it.
-
Medical risk is real
Bradycardia, electrolyte disturbance and refeeding syndrome can be fatal. Physical monitoring runs alongside therapy.
How the diagnosis is made
From first conversation to a clear plan.
The steps a UK GP and specialist team will normally follow, in order — so you know what to expect and why.
Phase 1 · Recognising
History, examination and basic tests
Phase 2 · Confirming
Weight trajectory and screening tools
Phase 3 · Managing
Specialist referral and family involvement
- 01
Recognising
Sensitive history and physical examination
A non-judgemental conversation covering eating patterns, behaviours, weight history and mood — with a careful physical check.
- 02
Recognising
Bloods
Electrolytes, LFTs, TFTs and phosphate — phosphate matters especially for refeeding risk.
- 03
Recognising
ECG
Looking for bradycardia and QT prolongation — both are red flags in low-weight patients.
- 04
Confirming
BMI and weight trajectory
A single BMI matters less than the direction and speed of change over recent weeks and months.
- 05
Confirming
SCOFF questionnaire
A short five-question screen that flags likely eating-disorder patterns.
- 06
Managing
Specialist referral
Joint psychiatry and dietetic referral to a specialist eating-disorder service (SEDIS) — the sooner, the better.
- 07
Managing
Family involvement
Family are part of treatment, especially for children and adolescents — they’re not a bystander.
Typical timeline: 2–4 weeks from first appointment to a settled specialist plan.
Types & signs
The main patterns to recognise.
Eating disorders show up in different shapes. Here are the main patterns — and the red flag that means don’t wait.
-
Anorexia nervosa
Restriction of intake with intense fear of weight gain and distorted body image — often with over-exercise.
-
Bulimia nervosa
Recurrent binge-eating episodes followed by compensatory behaviours — vomiting, laxatives or fasting.
-
Binge-eating disorder
Recurrent binges without compensatory behaviours — associated with distress, shame and weight gain.
-
ARFID
Avoidant-restrictive food intake disorder — sensory aversions or fear of aversive consequences, not body-image driven.
-
Orthorexia patterns
Rigid preoccupation with “clean” or “healthy” eating that narrows the diet and disrupts daily life.
-
Excessive exercise
Compulsive activity that continues through injury, illness or exhaustion — driven, not enjoyed.
-
Purging behaviours
Self-induced vomiting, laxative or diuretic misuse — with dental erosion, parotid swelling and electrolyte risk.
-
Red flag
Bradycardia (<40), electrolyte disturbance or syncope — call 999 or arrange urgent SEDIS admission.
Treatment
How eating disorders are treated in the UK.
Specialist psychological therapy first, medical monitoring alongside, medication where it helps — what each option does, and when it fits.
-
CBT-ED
Cognitive behavioural therapy for eating disorders — the mainstay talking therapy for adults with bulimia, binge-eating and many with anorexia.
-
Maudsley FBT (adolescents)
Family-based treatment — parents take a lead role in refeeding at home, with the clinical team supporting them.
-
MANTRA (adult anorexia)
Maudsley Anorexia Nervosa Treatment for Adults — a structured, motivation-focused therapy.
-
Nutritional rehabilitation
Careful, structured restoration of eating and weight — always with dietetic and medical support.
-
Refeeding protocol (specialist)
Slow calorie escalation, phosphate/potassium/magnesium replacement and cardiac monitoring — never done alone at home.
-
Inpatient or day-programme SEDIS
Intensive specialist admission when weight, bloods or risk demand more than outpatient care can safely give.
-
Fluoxetine (bulimia nervosa)
Higher-dose fluoxetine is licensed and evidence-based for bulimia — used alongside CBT-ED, not instead of it.
-
Lisdexamfetamine (specialist)
Licensed by specialists for moderate-to-severe binge-eating disorder in adults — with careful cardiovascular monitoring.

Red flags
When to reach out — urgently.
These are the situations where eating disorders become a medical emergency. If any of these apply, contact your specialist team, 111, or 999.
-
Bradycardia
A resting heart rate under 40 in low-weight patients is a medical emergency — arrange same-day assessment.
-
Hypokalaemia
Low potassium — commonly from vomiting or laxative misuse — risks fatal cardiac arrhythmia.
-
Hypophosphataemia
A hallmark of refeeding syndrome. Requires urgent replacement in a specialist setting.
-
Syncope
Fainting or near-fainting in someone with restricted intake is never routine — urgent review needed.
-
Post-refeeding cardiac failure
Breathlessness, oedema or new tachycardia after starting to eat again — treat as an emergency.
-
Rapid weight loss
Losing more than 1kg per week in an already low-weight patient warrants urgent specialist input.
-
Comorbid diabetes (diabulimia)
Insulin omission for weight loss in type 1 diabetes is life-threatening and needs joint diabetes–ED care.
-
Pregnancy with active ED
Active restriction, purging or binge-eating in pregnancy needs specialist perinatal input for mother and baby.
-
Purging with dental erosion
Visible enamel loss or parotid swelling is a marker of hidden, frequent vomiting — bring it into the conversation.
Living with it
Recovery is possible, and it isn’t solo.
Four things that make the biggest difference day to day — structure, support, medication and reviews.
A quiet reminder
Regular eating is treatment.
You don’t have to feel hungry, or feel motivated, for regular meals to start doing their work.
- 01 Structure
Regular eating comes first
Three meals and two snacks a day — even without appetite — is the foundation every therapy builds on.
- 02 Support
Family and carers are part of it
FBT, carer skills groups and Beat’s helpline exist because recovery is rarely a solo project.
- 03 Medication
A support, not a shortcut
Medication has a real but limited role — fluoxetine for bulimia, lisdexamfetamine (specialist) for binge-eating. Neither replaces therapy.
- 04 Reviews
Track weight and bloods
Regular monitoring — weight, ECG, electrolytes — catches deterioration early and keeps refeeding safe.
Frequently asked
Everything we get asked about eating disorders.
Quick answers on types, refeeding, family therapy and when admission is needed.
-
What is the difference between anorexia, bulimia and binge-eating disorder?
Anorexia involves restriction of intake with intense fear of weight gain. Bulimia involves binges followed by compensatory behaviours (vomiting, laxatives, fasting). Binge-eating disorder involves binges without those compensatory behaviours.
-
What is refeeding syndrome and why does it matter?
Refeeding syndrome is a shift of electrolytes — especially phosphate, potassium and magnesium — that can occur when a malnourished person starts eating again. It can cause cardiac failure and death, which is why refeeding is done under specialist supervision.
-
What is a SEDIS?
A Specialist Eating Disorder Inpatient or Intensive Service — the multidisciplinary NHS or independent service that provides inpatient, day-programme and intensive outpatient care for moderate-to-severe eating disorders.
-
Is family-based therapy really first-line for adolescents?
Yes. NICE recommends Maudsley family-based treatment (FBT) as the first-line therapy for children and young people with anorexia nervosa — parents take a lead role in restoring eating, with the clinical team coaching them.
-
Can medication treat eating disorders?
Medication has a limited but real role. Fluoxetine is licensed for bulimia nervosa alongside CBT-ED. Lisdexamfetamine is licensed by specialists for moderate-to-severe binge-eating disorder. Medication alone is not a treatment for anorexia.
-
When is urgent admission needed?
Bradycardia under 40, significant electrolyte disturbance, syncope, post-refeeding cardiac symptoms or rapid weight loss all warrant urgent SEDIS or medical admission. Call 999 or contact the eating-disorder service on call.
