Eating disorders explained

What eating disorders are

An eating disorder is a mental health condition where a person copes with difficult feelings or situations through their eating, food or body image. It is not about vanity or willpower, and it is not a choice. The thoughts and behaviours can feel like they take over, and the person often feels trapped and ashamed. Eating disorders frequently occur alongside anxiety, depression or low self-esteem, and can develop from a mix of genetic, psychological and social factors, sometimes triggered by stress, bullying, dieting or trauma. They affect people of every gender, age, size and background — including those who look outwardly well. Understanding them as serious health conditions, rather than moral failings, is essential to getting people the help they need.

The main types

There are several kinds. Anorexia nervosa involves restricting food and sometimes over-exercising, driven by an intense fear of weight gain and a distorted view of one's body, leading to a very low weight. Bulimia nervosa involves cycles of eating large amounts and then trying to undo it by vomiting, using laxatives, fasting or over-exercising. Binge eating disorder involves regularly eating large amounts in a distressing, out-of-control way without the purging seen in bulimia. There is also a wider group, sometimes called OSFED, where symptoms are serious but do not fit neatly into one category, and ARFID, where eating is limited by things such as sensitivity to textures rather than body image. All of these are serious and deserve help.

Why they are dangerous

Eating disorders carry serious physical and mental risks and can be fatal — anorexia has one of the highest death rates of any mental health condition. Starvation, purging or bingeing can damage the heart, cause dangerous changes in body salts that can trigger irregular heartbeats, weaken bones, harm fertility, and affect the gut, teeth and kidneys. Very low weight or rapid weight loss can become a medical emergency. The mental toll is heavy too, with high rates of depression, anxiety and thoughts of self-harm. Warning signs include preoccupation with food, weight or calories, secrecy around eating, going to the toilet straight after meals, excessive exercise, mood changes, feeling cold, and withdrawing from friends. Because sufferers often hide symptoms, concern from others matters greatly.

Getting help early

Recovery is possible, and the earlier someone gets help the better the outcome. A GP is the usual first step and can refer to a specialist eating disorder service; in the UK there are dedicated services for children, young people and adults. Treatment usually combines talking therapies tailored to the disorder, help to restore healthy eating patterns, support for physical health, and treatment of any linked anxiety or depression. Family involvement is especially important for young people. The charity Beat runs a helpline and online support for people affected and their families. It helps to approach someone with compassion, focusing on your worry for them rather than on food or weight, and to encourage them gently to seek help rather than waiting.

Supporting someone and staying safe

If you are worried about someone, choose a calm, private moment, tell them what you have noticed and that you care, and listen without judging. Avoid comments about appearance or weight, and do not try to police their eating, as this often increases secrecy and distress. Encourage them to see a GP or contact Beat, and offer to help them make the appointment. Look after yourself too, as supporting someone can be hard. Some situations need urgent help: fainting, chest pain, a very low or fast heartbeat, confusion, or thoughts of ending life. In these cases seek urgent medical care. For crisis support, contact Samaritans on 116 123 or NHS 111 mental health option, and call 999 if life is in immediate danger.
