Eating disorders are serious conditions which involve negative thoughts and feelings about body weight and food, leading to dangerous eating behaviours. These behaviours can significantly impact the ability to get adequate nutrition. Eating disorders can harm the heart, digestive system, bones, and teeth, and be associated to other diseases.
Eating disorders often develop in the teen and young adult years, although they can develop at all ages. While more common among girls, eating disorders can affect boys too. With treatment, you can return to healthier eating habits and sometimes reverse serious complications caused by the eating disorder.
The most common eating disorders are anorexia nervosa, bulimia nervosa and binge-eating disorder.
In recent years, clinicians have realized that a significant number of individuals with eating disorders did not fit into the Diagnostic and Statistical Manu¬al of Mental Disorders IV (DSM-4). The fifth edition of the (DSM-5) includes several changes to better represent the symptoms and behaviours of patients dealing with eating disorders. Among the most substantial changes are recognition of binge eating disorder, revisions to the diagnostic criteria for anorexia nervosa and bulimia nervosa, and inclusion of pica, rumination and avoidant/restrictive food intake disorder.
