Eating Disorders

What is an Eating Disorder?

When a person has an unhealthy attitude to food that takes over their life and makes them ill physically & / or mentally then it is likely that they will have an eating disorder.

There are lots of different eating disorders which include eating too much, not eating enough and obsessing over body shape and weight. There is no single cause. Eating disorders can affect people of all ages, genders, ethnic groups and backgrounds and are complex mental illnesses that can develop at any time – They are not a lifestyle choice or a “phase”.

Eating Disorders can cause significant harm and distress, but they can be treated. With the correct treatment recovery is possible.

Common types of eating disorders

Anorexia Nervosa

Anorexia Nervosa occurs when a person tries to keep their weight as low as possible. The way they do this will be through over exercising, not eating enough food or both.


In Bulimia a person may lose control of how much they eat. They may binge on food by eating a lot within a short time and then will deliberately make themselves sick or use laxatives to stop themselves gaining weight. Again they may exercise too much or restrict what they eat.

Binge Eating Disorder (BED)

If a person regularly loses control of their eating and eats large portions of food until they are uncomfortably full then this could be a Binge Eating Disorder (BED). Overeating in this way will often lead to upset and guilt.

other specified feeding or eating disorder (OSFED)

When the symptoms don’t match exactly with a diagnosis of anorexia, bulimia or binge eating disorder then a person may be diagnosed with other specified feeding or eating disorder (OSFED)

When to see your GP

If you think you have an eating disorder or are worried about your relationship with food, your body or your exercise habits then book an appointment to speak to your GP. It is very important to access treatment as early as possible, as earlier treatment means a greater chance of fully recovering from your eating disorder.

Your GP will be responsible for your initial diagnosis and should help to coordinate your care, at least in the early stages of treatment. If they determine you may have an eating disorder, they should refer you to an eating disorders specialist.

Word from our GP

 These problems are very common in patients of all ages and help is needed as early as possible. If a patient or their relative / friend is suspecting an eating disorder please seek help from your GP. BEATS on line is also a good resource to look at. Social media can have a massive negative influence on people with eating disorders.
