Eating disorders: what they are, signs and where to seek help

What is an eating disorder?

An eating disorder persistently changes a person’s relationship with food and can affect health and daily life [1][2]. It can take different forms. Concerns may centre on eating, compensating, avoiding foods or controlling the body.

Understanding what is happening requires an interview and physical and psychological assessment [1]. One isolated behaviour is not enough to make a diagnosis. Even so, distress or changes in habits are reasons to seek help early.

Dieting to resolve the problem usually adds more restriction. In binge-eating disorder, weight loss is not a treatment goal, and clinical guidance advises against dieting while the disorder lasts because it often triggers binge eating [1]. If someone is already eating very little, they also need a medical assessment.

An eating disorder can affect study, work, relationships and the ability to eat with others. Sometimes the person feels ashamed or tries to hide what is happening [2]. Listening to that distress is part of assessment.

There is a difference between a passing difficulty and a problem that becomes part of daily life. Duration is one part of the conversation, but it is not used on its own to decide whether treatment is warranted [1]. Describe what is happening now, even if it started recently.

What types of eating disorders are there?

The names below are intended to guide the conversation, not to choose a diagnosis [1][2]. Each situation needs its own assessment.

• Anorexia nervosa. Often involves significant food restriction and fear of gaining weight; assessment also considers physical health [1][2].
• Bulimia nervosa. Binge-eating episodes involving a sense of loss of control are followed by behaviours intended to compensate [1][2].
• Binge-eating disorder. There are episodes of losing control while eating and distress, without the compensation characteristic of bulimia [1][2].
• Avoidant/restrictive food intake disorder. The person eats little or has very limited variety because of low interest, aversion to textures or smells, or fear of choking or vomiting [2].
• Orthorexia. It is not an official diagnosis. It describes a rigid concern about eating in a way considered healthy, which may cause distress and isolation; Psychology assesses the underlying problem.
• Vigorexia (muscle dysmorphia). This is an intense concern about not being muscular enough. Classifications list it as muscle dysmorphia, a form of body dysmorphic disorder that shares features with eating disorders. Our muscle dysmorphia guide explains it.
• Pica. It involves persistently ingesting substances that are not food and requires individual clinical assessment [3].

There are also presentations that do not fit these names and still need care [1]. The label may change after assessment. You do not need to find the exact term before asking for help.

What is the difference between anorexia and bulimia?

The general distinction is in the pattern of behaviour. Restriction is usually predominant in anorexia. In bulimia, binge-eating episodes are followed by attempts to compensate [1][2]. One person may show behaviours from different patterns. See “Does sugar addiction exist? What science says”.

Aspect	What to know	Assessment
Behaviours	Anorexia nervosa and bulimia nervosa can involve some of the same behaviours.	One behaviour alone does not determine the difference between them.
Physical appearance	Physical appearance does not determine the difference [2].	Weight alone does not determine referral.
Diagnosis	Diagnosis requires clinical assessment.	Professionals assess the whole picture and physical risk [2].

The table is not a way to classify anyone. Vomiting may occur in anorexia and restriction between episodes may occur in bulimia [1]. Professionals assess the whole picture and physical risk; weight alone does not determine referral [1].

How can you recognise that you need help?

Look at changes in your life rather than a number. Perhaps you are starting to avoid shared meals, feel distressed when a food rule changes or spend a lot of time compensating for what you eat [1]. None of these observations alone confirms an eating disorder.

Food may determine when you go out, whom you see or how much you enjoy a day. A concern about your body may also take up hours you used to spend on other things. If this is happening to you, a medical or psychological consultation may help you understand it.

Some people maintain their routine while feeling overwhelmed. That is why it is helpful to talk about distress even if things look fine from the outside. Assessment can begin before a complication appears [1].

Eating because you are nervous or bored from time to time is not the same as losing control around food and feeling distressed about it. If you are unsure, our guide to anxiety around food can help distinguish them. If loss of control happens repeatedly, ask for an assessment.

What can you do if you are worried about someone close to you?

Changes in behaviour may appear before any change in the body. The person may stop eating with others, become very distressed when routines change or withdraw from activities they used to enjoy [1]. Observe without monitoring or jumping to conclusions.

Find a calm moment and talk about what you have noticed. You can say you are concerned about their wellbeing and are available to accompany them to make an appointment. A conversation focused on weight, the plate or appearance may close the door.

Listening without arguing about whether they eat too much or too little usually helps keep the conversation open. Ask how they are feeling and what support they would accept. If they do not want to talk now, you can offer your support again later.

For a minor, share your concern with their caregivers and request a health assessment [1]. If there is a physical emergency or risk of self-harm, follow the immediate-help instructions. Do not wait to resolve the family conversation.

Someone close to the person may also need guidance on how to support them. They can ask the assessing team, while respecting the person’s privacy. This means support does not depend on improvising a response during a meal or an argument.

Can you have an eating disorder at a normal weight?

Yes. An eating disorder can occur at any weight, at any age and in any sex [2]. Clinical guidance advises against using a single body measure, such as body mass index, to decide whether to offer treatment [1]. Rapid weight loss, compensatory behaviours and physical condition deserve assessment in their own right [1][4].

Hearing “but you look fine” can make it harder to talk about what is happening. That is why medical assessment asks about behaviours and symptoms, and includes vital signs, examination and tests as appropriate [1]. Vomiting, laxatives or periods of eating very little matter even if the scales hardly change; you can describe them approximately if you do not remember every episode.

Why do eating disorders develop?

There is no single cause. Genetic, biological, psychological and social factors play a part, along with the way a person copes with emotions [2]. Eating disorders can affect anyone at any age [2].

A strict diet, a comment about the body or a stressful period may coincide with the onset without being the whole explanation. Appearance-related pressure is one of these factors; our guide to body image discusses it in depth.

The cause cannot be identified by looking at the body or one behaviour. During assessment, describing when the distress began and what changed around that time helps explain the context without looking for someone to blame. The relationship between food and mood is discussed in our guide to food and mental health.

What we see in consultations

In consultations, we see many people arrive asking for a meal plan. First, we need to listen to what is happening and check whether a specialist assessment is needed. That conversation prevents distress from becoming another food rule.

Three ideas we often hear delay seeking help: “It cannot be an eating disorder if they eat normally in front of everyone”, “that happens to teenage girls” and “if I try harder, I can control it”. Eating disorders affect people of all ages and sexes, and sometimes people eat in secret because of shame [2]. Restriction and binge eating are not explained by a lack of willpower either.

If you are already following a weight-loss plan and notice that food is taking up more and more mental space, tell the professional supporting you. The guide to fad diets can help identify misleading plans. Take their instructions to the appointment, if you still have them, and explain what has changed since you started.

Where can you seek help for an eating disorder?

Your GP is usually the first point of contact. They assess physical health and guide referral to an eating-disorder service or specialist psychology, depending on your age and area [1]. When booking, it is enough to say: “I’m worried about my relationship with food.”

If you are already seeing a mental health professional, also tell them what is happening with food. Asking for an assessment does not commit you to accepting a label or a fixed plan. It helps you learn about options and make decisions with support.

While waiting for your appointment, write down what you want to say: behaviours, emotions, physical symptoms and what has become difficult in your day. A recent situation described in your own words, such as a meal you avoided and how you felt, provides more context than a number or a label found online. If the wait becomes long or you get worse, call your GP again; for emergencies, follow the “When to seek medical care” section.

If you are supporting someone, offer to find the clinic, call or go with them, and let them take part in the decision. Non-profit associations can also guide family members, such as Associació contra l’Anorèxia i la Bulímia in Catalonia.

Who coordinates care, and what does nutrition do?

Care is coordinated by an eating-disorder service or specialist psychology, with medical assessment and nutritional support when appropriate [1][5]. Psychiatry is involved in some cases. The team adjusts the intensity of care to the person’s physical and psychological situation.

Psychology works on the relationship with food, emotions and behaviours that maintain the problem. Medicine reviews possible physical consequences and decides whether urgent care is needed. Nutrition supports eating as part of the agreed plan.

A standalone nutritional intervention does not replace this joint work [1]. If an eating plan is needed, it is tailored to the person and the circumstances. We do not provide menus, quantities or monitoring rules to follow on your own.

There are specific psychological treatments for binge-eating disorder [1][5]. The specialist Psychology team will assess which is suitable for you; nutrition can support the process when needed.

Support may include family members or people close to the person when appropriate [1]. This involvement is often especially important for minors. No one should have to carry the task of identifying, treating and monitoring the problem alone.

Can you recover from an eating disorder?

Yes: people with an eating disorder can recover with treatment [2]. The earlier treatment starts, the easier the path often is. The process may need adjustments, and a relapse does not erase progress.

For adolescents, involving family in treatment improves outcomes [2]. For adults, the treatments with the strongest support are psychological therapies specific to eating disorders [1][5]. You can ask the team who coordinates decisions and whom to contact if something changes.

During the assessment, ask how to contact the team between appointments and which signs mean you need more urgent care. If you want to involve someone close to you, talk with the team about how they can support you. Having these answers to hand makes it easier to ask for support if your situation changes.
