Eating disorders are diagnosed by medical doctors or psychologists in Canada and the definitions are outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The DSM-5 lists several feeding and eating disorders:
- Anorexia Nervosa
- Bulimia Nervosa
- Binge-eating Disorder
- Feeding Disorders generally diagnosed in childhood such as Avoidant/Restrictive Food Intake Disorder (ARFID), Rumination Disorder and Pica.
The causes of eating disorders are not completely understood but can be attributed to an array of biological, social, genetic, and psychological factors. Eating Disorders can involve restriction (limiting food intake), bingeing, purging, or a combination of these behaviours. Anorexia Nervosa and Bulimia Nervosa are life threatening disorders affecting both women and men. Individuals suffering from an eating disorder can attempt to hide the disorder from others, leading to isolation. Those with eating disorders may also suffer from depression, anxiety and other health problems. Treatment through therapy can be vital as part of a treatment plan for eating disorders.
