What is anorexia?

A serious mental health condition that affects food, feelings and the whole body.

Anorexia nervosa is an eating disorder and a serious mental health condition. A person strictly limits how much they eat, driven by a strong fear of gaining weight. Many people also see their body as bigger than it really is.

Anorexia is not a diet, a phase or about vanity. It is an illness of both the mind and the body. Without treatment it tends to get worse, which is why early help matters so much.

Doctors sometimes describe two patterns. In one, a person mainly restricts food. In the other, restricting comes together with episodes of bingeing or trying to get rid of food. Both are equally serious.

This guide is for understanding, not for diagnosing yourself or anyone else. Only a qualified professional can assess an eating disorder. Please talk to your clinical provider if anything here feels familiar.
New to eating disorders? The “Eating disorders” guide covers all the types, myths and warning signs. This guide goes deeper on anorexia only.

By the numbers

Anorexia is less common than other eating disorders, but very serious, and recovery is common.

These numbers come from large surveys and long-term research. Many people with anorexia are never counted, because they never get diagnosed.

United States

0.6%of U.S. adults will have anorexia at some point in their life (NIMH, survey 2001–2003).
0.9% / 0.3%of women / men in the same survey had anorexia in their lifetime. It affects men too (NIMH).
33.8%Only about 1 in 3 adults with anorexia ever got treatment for it (NIMH, 2001–2003).
Under 6%of all people with eating disorders are medically “underweight” (research shared by ANAD). You cannot tell by looking.

Recovery

~2 in 3women with anorexia had recovered when researchers checked in about 22 years later (62.8%, Eddy et al., 2017).
About halfof those who had not recovered after 9 years went on to recover by about 22 years. It is never too late (Eddy et al., 2017).

What anorexia can feel like inside

The thoughts and feelings that keep anorexia going. Tap any card.

From the outside, anorexia can look like it is all about food. On the inside, it is often about fear, control and self-worth. Understanding this helps people respond with kindness instead of frustration.

😨 FearA strong, constant fear of gaining weight.
Read more

The fear at the heart of anorexia can feel overwhelming, and it does not go away just because someone is told they are “fine”. It can make eating feel frightening, even when the person wants to eat.

The fear is a symptom of the illness. It is real to the person, even when it does not match what others see.
🪞 A distorted view of the bodySeeing yourself as bigger than you are.
Read more

Many people with anorexia believe they are larger than they really are, even when they are very unwell. This is part of the illness, not stubbornness. Arguing about how someone looks rarely helps.

People may also deny how serious their low weight or health problems are. This can make it hard for them to accept help at first.

🎛️ ControlFood rules can feel like the one thing that is in your hands.
Read more

Some people say restricting food first gave them a sense of control when life felt chaotic or painful. Over time, the rules start to control them instead.

Recovery often includes finding new ways to feel steady and safe, like talking things through, creative outlets and trusted routines.
🏆 PerfectionismVery high standards, and harsh self-criticism.
Read more

Perfectionism, anxiety, obsessive traits and low self-esteem are common in people who develop anorexia. Nothing ever feels “good enough”, including the body.

Therapy can help loosen these patterns, so worth is no longer measured by shape, size or achievement.

🔀 Mixed feelings about recoveryWanting to get better, and being scared to.
Read more

Many people with anorexia feel torn. Part of them wants to be well, and part of them is terrified of letting go of the illness. This is very common and is not a sign that someone doesn’t care.

Some therapies, like MANTRA, are built around this. They focus on what matters most to the person and on changing when they feel ready.

🗣️ The eating disorder “voice”Thoughts that feel like your own, but aren’t really you.
Read more

Many people describe anorexia as a critical voice that tells them they don’t deserve to eat, rest or be cared for. It can sound convincing because it speaks in your own words.

Families are often encouraged to separate the illness from the person: “I’m on your side, against the eating disorder.”

Try the “Me, not the eating disorder” worksheet in this guide to notice the difference.

Anorexia can affect anyone

Every gender, every age, every background and every body size. Tap any card.

Anorexia is most common in young women and often starts in the mid-teens. But men and women of any age can develop it. It can affect people of all body sizes and body types.

⚖️ Atypical anorexiaThe same illness, in someone who is not underweight.
Read more

Some people have all the thoughts and behaviours of anorexia, but their weight is in or above the “normal” range. This is called atypical anorexia. Because they don’t look how people expect, it is often missed.

A 2016 study of teens found that those with atypical anorexia had heart and blood pressure problems about as often as teens who were underweight. Their distress about eating and body image was even stronger.

Praise for weight loss can feed the illness. Any big weight loss in a young person is worth a check-up, whatever their size.
🎒 Teens & young peopleThe most common time for anorexia to start.
Read more

Anorexia typically starts in the mid-teens. In children and teens, it may show up as not growing or gaining weight as expected, rather than losing weight.

For under-18s, family therapy is usually the first treatment offered. Parents become part of the team.

🧔 Boys & menOften missed, and less likely to get treatment.
Read more

Men make up as many as 1 in 4 people with eating disorders. Men often don’t see their symptoms as a problem, and health professionals can sometimes downplay them.

Anorexia is not a “girls’ illness”. Men deserve the same understanding and care.
🌻 Adults & older adultsAnorexia can begin, or return, later in life.
Read more

Men and women of any age can develop anorexia. Stress and painful experiences, like trauma, can play a part at any stage of life.

It is never too late to get help. Treatment works at every age.
🌈 People of color & LGBTQ+ peopleSimilar rates, but less likely to be diagnosed.
Read more

People of color are affected by eating disorders at similar rates to white people, but are about half as likely to be diagnosed. LGBTQ+ young people are about three times as likely to have an eating disorder as their straight peers.

You can ask a provider about their experience with your culture or identity before you start.
🩰 Dancers, athletes & modelsPressure to be slim for work or sport raises the risk.
Read more

An intense focus on being slim, including pressure from work or sport, is a known risk factor. Dancers, models and athletes are examples.

The “Athletes’ mental health” guide has more on sport, pressure and support.

Changes others may notice

Gentle signs that someone may be struggling. Not a checklist. Tap any card.

Anorexia is often hidden, and people may say they are fine. Looking at the whole picture, over time, tells you more than any one sign.

🍽️ Around foodEating less, and food taking over their thoughts.

You might notice

  • Avoiding foods they see as “fattening”
  • Eating very little, or missing meals
  • Making excuses not to eat with others

  • Dry skin or hair loss
  • Feeling cold, tired, dizzy or lightheaded
  • Periods stopping, or not starting in younger girls
  • In children and teens, not growing as expected
Fainting, chest pain, a very fast or very slow heartbeat, or confusion need medical help right away. Call 911 in an emergency.
🏃 Movement & exerciseExercise that feels like a rule, not a joy.
Read more

Some people with anorexia exercise far more than is healthy. Exercise may feel like something they must do, even when they are tired, unwell or injured.

Having some of these signs does not mean someone has anorexia. Only a qualified professional can assess this — please talk to your clinical provider or therapist.

How anorexia affects the body and brain

An honest look at why care matters, and why there is hope.

When the body does not get enough food for a long time, it starts to starve. Nearly every organ can be affected. Many of these problems improve once eating improves.

Anorexia can affect

  • Bones: thinning bones (osteoporosis) and a higher risk of fractures
  • Brain: trouble concentrating and remembering
  • Growth: delayed growth and puberty in young people
  • Heart: a slow or irregular heartbeat and low blood pressure
  • Hormones: periods stopping, fertility problems and low sex drive
  • Immune system: getting ill more easily, and anemia
  • Kidneys, liver and gut: damage and constipation
  • Muscles: weakness and muscle loss

Starting to eat more after a long time of restriction must be done with medical support. A care team will plan this carefully and keep a close eye on the body while it heals.

Anorexia has one of the highest death rates of any mental illness. Some deaths come from physical problems and some from suicide. This is hard to read, but it is the reason early help and steady care matter so much.

If you are having thoughts of suicide, call or text 988 (U.S.), any time. If a life is in danger, call 911.

Why does anorexia happen?

No single cause, and nobody’s fault. Tap any card.

No one knows exactly what causes anorexia. Experts think it comes from a mix of biology, personality, life experiences and the world around us. Nobody chooses it.

🧬 Biology & family historyGenes and brain chemistry play a part.
Read more

Anorexia can run in families. A family history of eating disorders, depression, or alcohol or drug problems raises the risk. Differences in brain chemicals like serotonin and dopamine may also play a role.

🧠 Personality & mental healthAnxiety, perfectionism and low self-esteem.
Read more

Things that can add risk

  • Anxiety
  • Low self-esteem
  • Obsessive traits
  • Perfectionism
🌩️ Life experiencesHurtful comments, bullying, trauma and abuse.
Read more

Things that can add risk

  • Being bullied
  • Being criticised about eating, body shape or weight
  • Emotional, physical or sexual abuse
  • Trauma
If something painful happened to you, it was not your fault. Trauma-informed care can help with both.
📱 Culture & social pressureMessages that thinner is better.
Read more

Pressure from friends, culture, social media and some jobs or hobbies can push an intense focus on being slim. This is a known risk factor.

The “Healing your relationship with food” guide has ideas for cleaning up your feed and spotting diet culture.
Families do not cause anorexia. They are often one of the strongest parts of recovery.

What treatment looks like

Talking therapy, nutrition support and health checks, together. Tap any card.

Treatment is planned around each person. It usually brings together talking therapy, support from a dietitian, and regular checks on physical health. Nutrition advice alone is not enough. It works best alongside therapy.

👨‍👩‍👧 Family therapy (young people)Usually the first treatment for under-18s.
Read more

The young person and their family meet with a therapist to look at how anorexia has affected them and how the family can help. It also teaches ways to manage hard feelings and prevent relapse.

In the UK it is often around 18 to 20 sessions over a year, sometimes with group sessions alongside other families. Research suggests family-based treatment improves outcomes, especially for teens.

🧑 Adolescent-focused therapyOne-to-one therapy for teens.
Read more

This therapy works on fears about weight gain, self-image and identity, and building confidence in stressful situations. It runs over many months, with some family sessions too.

🧠 CBT for eating disordersA talking therapy for adults and young people.
Read more

CBT helps people understand the thoughts and feelings that keep anorexia going and learn new ways to cope. For adults it is often weekly for up to 40 weeks, with extra sessions at the start.

For young people, CBT is similar but includes some family sessions.

🧭 MANTRAA therapy built around what matters to you.
Read more

MANTRA is a therapy for adults. It focuses on what is important to the person and on changing behaviour when they feel ready. Family or carers can be involved.

🤝 SSCMSpecialist supportive clinical management.
Read more

In SSCM, a therapist explains how eating habits are linked to symptoms and helps the person build healthier eating over a series of weekly sessions.

🥕 Nutrition supportWorking with a dietitian to eat enough to heal.
Read more

A registered dietitian helps build a meal plan and regular eating, with check-ups along the way. For young people, the team also helps parents support eating at home.

🏥 Day care & hospitalExtra support when someone is very unwell.
Read more

Most people stay at home and go to appointments. Day programs or a hospital stay may be needed if there is a serious risk to health or safety. Care then steps back down as the person gets stronger.

Treatment may also help with other things like anxiety or depression. For questions about any part of your care, consult with your clinical provider.

Recovery is possible

It can take time, and it is rarely a straight line, but people do recover.

You can recover from anorexia, but it may take time, and recovery is different for everyone. Getting help as early as possible gives the best chance.

A long-term study followed women with anorexia for about 22 years. About two in three had recovered by then, and about half of those still unwell after 9 years recovered later. Recovery can keep happening, even after many years.

What recovery can include

  • Eating regularly and feeling less afraid of food
  • Feeling your worth is about much more than your body
  • Having energy for friends, hobbies, school or work again
  • Knowing your early warning signs and having a plan
  • Trusting people enough to ask for help

Setbacks can happen, especially during stress. They are part of recovery, not a failure. Ongoing support and regular check-ups after treatment help people stay well.

The “Healing your relationship with food” guide has practical steps for urges, food rules and relapse prevention.

How to support someone with anorexia

What helps, what to avoid, and looking after yourself too.

If you are worried about someone, you don’t need all the answers. Letting them know you care, giving your time, and listening is what matters most.

🗨️ Starting the conversationCalm, private and kind.
Read more

Try this

  1. Pick a calm, private moment, away from mealtimes.
  2. Say what you’ve noticed about their mood or wellbeing, not their size.
  3. Tell them what you value about them.
  4. Listen more than you talk.
  5. Encourage them to see a doctor or school nurse, and offer to go with them.

They may deny it or get upset. That is common. Try not to take it personally, and keep the door open.

🚫 Things to avoidSome well-meant words can hurt.
Read more
  • Arguing about food or watching every bite
  • Comments on weight, shape or looks, even “You look healthy”
  • Criticising or giving lots of advice
  • Simple fixes like “Just eat”
  • Talking about your own diet or “good” and “bad” foods
🧒 If you’re a parentYou are a key part of your child’s recovery.
Read more

For young people, family therapy is usually the first treatment. The care team will talk with parents and carers so they can support eating at home.

What helps

  • Acting early and speaking to your child’s doctor
  • Keeping up fun and connection that has nothing to do with food
  • Separating the illness from your child
  • Staying united with other caregivers
🌿 Looking after yourselfSupporting someone is hard. You matter too.
Read more

Recovery usually takes months or longer, with good days and bad days. It is normal to feel scared, tired or frustrated.

Ideas

  • Get your own counseling if you need it
  • Join a group for families, such as ANAD’s free support groups
  • Keep up your own sleep, meals and hobbies
  • Talk to someone you trust
If the person is under 18, tell a parent, school nurse or counselor. If you think they are in danger, get help right away.

When and where to get help

You don’t have to be “sick enough” to deserve support.

If you think you might have anorexia, see your doctor, even if you’re not sure. Bringing a friend or family member can help. Young people can also start with a school nurse or counselor.

ANAD Eating Disorders Helpline (U.S.): call 1-888-375-7767, Monday to Friday, 9am–9pm Central Time. It is free and offers support and referrals to treatment.
If you’re in crisis or having thoughts of suicide, call or text 988 (U.S.), any time. If a life is in danger, call 911.
