When to get urgent in-person care
Eating disorders can affect the heart and blood chemistry without much outward warning, which is why certain signs are never "wait and see". Call 112 if someone collapses, has a seizure, has chest pain, or has a very slow, racing or irregular heartbeat. Arrange urgent in-person medical care today for:
- fainting, blackouts, or dizziness on standing that keeps returning;
- palpitations, or a heartbeat that feels too slow, too fast or irregular;
- being unable to keep any food or fluids down;
- vomiting blood, or severe muscle weakness such as struggling to climb stairs;
- new confusion, drowsiness or disorientation;
- feeling very cold, with cold blue hands and feet, in someone who has been eating very little.
These signs matter at any body size and any age. In children and teenagers, thresholds for urgent review are lower still: when in doubt, be seen today.[1]
If you are having thoughts of harming yourself, call 112 in an emergency. You can also find your national crisis helpline at findahelpline.com. You do not have to wait for an appointment.
- Treated online: Assessment and referral online; treatment happens in specialist eating disorder services. The online consultation is a confidential first conversation, a medical-risk check and a referral to the right care.
- What it is: a mental health condition in which food, eating, weight or shape dominate thinking and behaviour; the main types are anorexia nervosa, bulimia nervosa, binge eating disorder and avoidant/restrictive food intake disorder (ARFID).
- Who it affects: people of every body size, gender and age; most start between 12 and 25, about 1 in 4 affected people are male, and nobody can diagnose an eating disorder by looking.
- Treatment: specialist talking therapies (eating-disorder-focused CBT for adults; family-based treatment for teenagers), with medical monitoring where needed; no medicine treats an eating disorder itself.
- Outlook: recovery is expected with treatment, over months rather than weeks, and the earlier treatment starts the better; most people recover fully or substantially.
- Emergency: call 112 if someone collapses, has a seizure, has chest pain, or has a very slow, racing or irregular heartbeat; fainting, inability to keep fluids down or new confusion need urgent in-person care, at any body size.
If any warning sign in the red box above is happening now, urgent in-person care today comes before any online appointment. Otherwise, a video consultation is a safe and private place to start, whether you are ready to say a lot or only a little, and whether the worry is about you or about someone you love.
Can an online doctor help with an eating disorder?
Yes, as the first step. A video consultation gives you a confidential conversation with a doctor who can recognise an eating disorder, check for signs that the body needs urgent attention, and refer you to specialist eating disorder services, which is where treatment happens.[1] Starting early genuinely improves the outlook.
How an online consultation helps with an eating disorder
- A conversation, not an examination: There is nothing to prepare and nothing to prove. You will not be weighed, photographed or asked to do anything on camera; you talk, the doctor listens, and you decide the pace.
- Recognition without judgement: Doctors treat eating disorders as serious illnesses, never as choices, vanity or attention-seeking. Saying the words out loud to someone medical, often for the first time, is the step most people describe as hardest, and it can happen from your own room.
- The medical-risk check: Careful questions about fainting, dizziness, heart symptoms, weakness and other physical signs, so that anything needing urgent in-person care is caught and acted on.
- The referral that matters: Treatment is specialist-led, so the consultation’s most valuable output is a proper referral to eating disorder services where you live, with the groundwork done and a doctor following up with you while it progresses.
How do I know if I have an eating disorder?
The most useful test is preoccupation and distress, not appearance: food, eating or your body dominating your thinking, rigid rules that cause panic when broken, secrecy or shame around eating, or your sense of worth rising and falling with your body. Eating disorders affect people of every body size, gender and age; nobody can diagnose one by looking.[2]
Signs that deserve a conversation include: eating feeling governed by rules that keep tightening; anxiety about eating with other people, and social plans quietly arranged around avoiding it; episodes of eating that feel out of control, followed by guilt or shame; exercise that feels compulsory rather than chosen, with distress when it is missed; checking or avoiding your reflection; and thinking about food or your body for more hours of the day than you would ever admit out loud. The body sends signals too: dizziness, feeling cold all the time, poor concentration, low energy, digestive problems, and periods becoming irregular or stopping. None of these on its own is a diagnosis; together, in patterns, they are a reason to talk to someone medical, and doing so commits you to nothing.
The main eating disorders, briefly
Anorexia nervosa involves restricting food alongside an intense fear of weight gain, and carries serious physical risk at any size.[3][5] Bulimia nervosa involves cycles of out-of-control eating followed by attempts to compensate, and strains the heart and blood chemistry even when nothing looks wrong from outside. Binge eating disorder, the most common, involves recurrent episodes of loss-of-control eating with intense shame afterwards, and responds well to treatment. ARFID involves very restricted eating driven by sensory distress or fear rather than body image. Mixed pictures that do not fit one label neatly (OSFED) are just as real, just as serious, and just as deserving of care.[2]
If you are worried about someone else
Choose a calm, private moment, not a mealtime. Say what you have noticed about them, not their body: "you seem anxious and far away lately, and I care about you" lands better than any comment about eating, and comments about weight or appearance usually make things worse, whatever direction they point. Expect denial or anger without treating it as failure; it often takes several conversations, and your consistency matters more than your phrasing. Do not police plates or negotiate bites, which turns love into surveillance. And you can speak to a doctor yourself first: a consultation about how to help someone you love, and how referral works where you live, is a completely legitimate use of an appointment.
When is an eating disorder a medical emergency?
When the body starts failing: fainting or collapse, chest pain, a very slow, racing or irregular heartbeat, seizures, vomiting blood, inability to keep fluids down, severe weakness or new confusion. Repeated vomiting or prolonged restriction can disturb blood salts that the heart depends on, often with little outward warning, which is why these signs mean urgent care today, at any body size.[1]

See available times →What the doctor checks in an online eating disorder consultation
Gently, and at your pace. There is no interrogation and no lecture. The doctor will typically cover:
- Your story, in your words: how things are with food and how long it has felt this way, told however you can tell it; half-sentences are fine, and the doctor knows how to help with the rest.
- How daily life is affected: energy, concentration, work or school, friendships, and the space this is taking up in your head.
- Physical-risk questions: fainting, dizziness on standing, palpitations, weakness, feeling cold, digestive symptoms and changes to periods, because these decide how urgent things are.
- Mood and safety: depression and anxiety travel closely with eating disorders and are asked about plainly and kindly, including thoughts of self-harm.
- What you want to happen next: some people want a referral straight away; others need one conversation first. Both are respected, with honesty about risk either way.
- Who and what is around you: family, friends, and the specialist services available where you live, so the plan fits your actual life.
The doctor will not comment on your body, set food rules, or hand you a diet. You can bring a parent, partner or friend into the call if that makes it easier.
How are eating disorders treated?
With specialist talking therapies, delivered by eating disorder services, alongside medical monitoring where needed. For adults that usually means eating-disorder-focused cognitive behavioural therapy; for children and teenagers, family-based treatment has the strongest evidence; guided self-help programmes are often the first step for binge eating disorder.[1][4] Recovery is genuinely expected with treatment: it takes months rather than weeks, wobbles are part of the path, and full recovery is common, which is worth saying because hopelessness is one of the illness’s symptoms.
Medication honesty matters here more than almost anywhere. No medicine treats an eating disorder itself; the treatments that work are psychological.[1] A doctor may treat depression or anxiety that travels alongside, after proper assessment, and a prescription is never issued without a consultation. Nothing is ever prescribed to change weight or appetite, weight-loss medicines have no place anywhere near an eating disorder, and this page will never link dieting content. If part of you is hoping a doctor will help you eat less, that part deserves the conversation most of all, and it will be met with care, not a prescription.
When an eating disorder is assessed online, and when you need in-person care
Assessed online: first confidential conversations, for you or for someone you love; recognition and honest assessment; the medical-risk check; referral to specialist eating disorder services with the groundwork done; guidance for parents and partners on what to say and what not to say; and care for the anxiety and low mood that so often travel alongside, while specialist care is arranged.
In-person care: anyone with physical warning signs goes to same-day in-person care, and collapse, chest pain or an irregular heartbeat goes to 112, including mid-consultation; everyone with a likely eating disorder is referred onward, because ongoing treatment belongs with specialist services, and pretending otherwise would be the opposite of care; children and teenagers go promptly to specialist child and adolescent services, with lower thresholds for urgency; and pregnancy alongside an eating disorder means specialist and maternity care working together, arranged without delay. Support for the stress this places on families is real too; the stress page is written for exactly that kind of load.

Frequently asked questions about eating disorders
What is an eating disorder?
An eating disorder is a mental health condition in which thoughts about food, eating, weight or body shape take over and drive behaviour: restricting, bingeing, purging, compulsive exercise or rigid rules that cause panic when broken. The main types are anorexia nervosa, bulimia nervosa, binge eating disorder and ARFID, and all of them occur at every body size.
How do I know if I have an eating disorder?
The most useful test for an eating disorder is preoccupation and distress, not appearance: food, eating or your body dominating your thinking, rules that cause panic when broken, secrecy or shame around eating, or your sense of worth rising and falling with your body. Feeling not ill enough is itself one of the commonest symptoms. If any of this is familiar, it is reason enough to talk to a doctor.
What causes eating disorders?
Eating disorders have no single cause. Genes contribute, so they run in families; so do anxiety, perfectionism and low self-esteem, dieting itself, bullying or comments about weight, stressful or traumatic events, and a culture that prizes thinness. Dieting is the commonest trigger, because restriction changes how the brain responds to food, which is why an eating disorder is never a choice.
Do I need a diagnosis before booking, or to be "ill enough"?
No. The feeling of not being ill enough is one of the most common symptoms of an eating disorder. If food, eating or your body is taking up more of your life than feels right, that is reason enough. Eating disorders occur at every body size, and an early conversation improves the outlook.
How are eating disorders treated?
Eating disorders are treated with specialist talking therapies delivered by eating disorder services, alongside medical monitoring where needed. For adults that usually means eating-disorder-focused cognitive behavioural therapy; for teenagers, family-based treatment has the strongest evidence; guided self-help programmes are often the first step for binge eating disorder.
Can an online doctor prescribe medication for an eating disorder?
No medicine treats an eating disorder itself, so no honest doctor prescribes one for it, online or anywhere. The treatments that work are specialist talking therapies. A doctor may treat depression or anxiety alongside an eating disorder, after a full assessment, and nothing is prescribed without a consultation.
Can you fully recover from an eating disorder, and how long does it take?
Yes. Full recovery from an eating disorder is common with treatment, and partial recovery with a much better life is more common still. It takes months rather than weeks, typically 6 to 12 months of therapy and often longer for anorexia nervosa, and wobbles along the way are part of the path, not a sign that treatment has failed.
When is an eating disorder a medical emergency?
An eating disorder becomes a medical emergency when the body starts failing: fainting or collapse, chest pain, a very slow, racing or irregular heartbeat, seizures, vomiting blood, inability to keep fluids down, severe weakness or new confusion. Repeated vomiting or prolonged restriction can disturb the blood salts the heart depends on with little outward warning, so these signs mean urgent in-person care, at any body size.
What helps while specialist eating disorder care is arranged?
While specialist eating disorder care is arranged, aim for regular eating (three meals and snacks at roughly set times, without compensating afterwards), tell one trusted person, step away from weighing, calorie apps and body-checking, and keep the follow-up appointments with the doctor so physical risk is watched. Self-help guides based on CBT can help with binge eating; they are a bridge to treatment, not a substitute for it.
Can I talk to a doctor about someone else's eating?
Yes, and it is one of the best uses of a consultation. The doctor can help you judge how worried to be about a possible eating disorder, spot signs that need urgent care, plan what to say and what to avoid saying (comments on weight and appearance rarely help; concern for how they are feeling does), and explain how specialist services work.
Will the doctor tell my family or anyone else?
Consultations about an eating disorder are private and confidential. Doctors involve others only when someone is at serious risk, they discuss it with you first wherever possible, and they explain honestly how specialist services are involved. Fear of being reported keeps many people away for years, and it is usually unfounded.
What happens after the referral?
Specialist eating disorder services assess you and agree a treatment plan, usually built around talking therapy, with medical monitoring where needed. While the referral progresses, your doctor can follow up with you, watch the physical-risk signs, treat anxiety or low mood alongside, and escalate if anything changes.
