An eating disorder is a mental health condition where you use the control of food to cope with feelings and other situations.
Unhealthy eating behaviors 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.
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.
