Eating disorders are serious mental illnesses that involve disordered eating behaviour. This might mean limiting the amount of food eaten, eating very large quantities of food at once, getting rid of food eaten through unhealthy means (e.g. purging, laxative misuse, fasting, or excessive exercise), or a combination of these behaviours. It’s important to remember that eating disorders are not all about food itself, but about feelings. The way the person interacts with food may make them feel more able to cope, or may make them feel in control.
Eating disorders include anorexia, bulimia, binge eating disorder and other specified feeding or eating disorder. They can affect anyone of any age, gender or background. It is possible to move between eating disorders.
Characterised by extreme low weight created through deliberate restriction of calorie intake often coupled with excessive exercise. Someone with anorexia will have a different perception to others of their physical appearance.

Anorexia has the highest mortality rate of any mental illness. It is extremely important to seek expert advice and support if you suspect someone has anorexia, for example from the organisation Beat.
Anorexia can be treated through a number of therapies although recovery takes time.
People with bulimia are caught in a cycle of eating large quantities of food (called bingeing), and then trying to compensate for that overeating by vomiting, taking laxatives or diuretics, fasting, or exercising excessively (called purging).
During a binge, people with bulimia don’t feel in control of how much or how quickly they’re eating. Some people also say that they feel as though they’re disconnected from what they’re doing. The food eaten during a binge may include things the person would usually avoid. Episodes of bingeing are often very distressing.
