An eating disorder is a mental health condition where you use the control of food to cope with feelings and other situations.
Unhealthy eating behaviours may include eating too much or too little or worrying about your weight or body shape.
Anyone can get an eating disorder, but teenagers between 13 and 17 are mostly affected.
With treatment, most people can recover from an eating disorder.
Types of eating disorders
The most common eating disorders are:
- anorexia nervosa – trying to control your weight by not eating enough food, exercising too much, or doing both
- bulimia – losing control over how much you eat and then taking drastic action to not put on weight
- binge eating disorder (BED) – eating large portions of food until you feel uncomfortably full
Other specified feeding or eating disorder (OSFED)
A person may have an OSFED if their symptoms do not exactly fit the expected symptoms for any specific eating disorders.
OSFED is the most common eating disorder.
Find out more about OSFED on the Beat website
Avoidant/restrictive food intake disorder (ARFID)
ARFID is when someone avoids certain foods, limits how much they eat or does both.
Beliefs about weight or body shape are not reasons why people develop ARFID.
Possible reasons for ARFID include:
- negative feelings over the smell, taste or texture of certain foods
- a response to a past experience with food that was upsetting, for example, choking or being sick after eating something
- not feeling hungry or just a lack of interest in eating

Getting help for an eating disorder
If you think you may have an eating disorder, see a GP as soon as you can.
A GP will ask about your eating habits and how you're feeling, plus check your overall health and weight.
They may refer you to an eating disorder specialist or team of specialists.
It can be very hard to admit you have a problem and ask for help. It may make things easier if you bring a friend or loved one with you to your appointment.
You can also talk in confidence to an adviser from eating disorders charity Beat by calling their adult helpline on 0808 801 0677 or youth helpline on 0808 801 0711.
Getting help for someone else
It can be difficult to know what to do if you're worried that someone has an eating disorder.
They may not realise they have an eating disorder. They may also deny it, or be secretive and defensive about their eating or weight.
Let them know you're worried about them and encourage them to see a GP. You could offer to go along with them.

Treatment for eating disorders
You can recover from an eating disorder, but it may take time and recovery will be different for everyone.
If you're referred to an eating disorder specialist or team of specialists, they'll be responsible for your care.
They should talk to you about the support you might need, such as for other conditions you have, and include this in your treatment plan.
Your treatment will depend on the type of eating disorder you have, but usually includes a talking therapy.
You may also need regular health checks if your eating disorder is having an impact on your physical health.
Your treatment may also involve working through a guided self-help programme if you have bulimia or binge eating disorder.
Most people will be offered individual therapy, but those with binge eating disorder may be offered group therapy.

Treatment for other specified feeding or eating disorder (OSFED) will depend on the type of eating disorder your symptoms are most like.
For example, if your symptoms are most like anorexia, your treatment will be similar to the treatment for anorexia.
