Eating disorders are common illnesses that are very serious and can be fatal. These disorders refer to changes in the eating and exercise behaviours of individuals as well as thoughts or emotions surrounding eating. Some possible signs of an eating disorder are preoccupations with body weight, body shape, and food. 

Common eating disorders include: 

• Anorexia nervosa
• Bulimia nervosa
• Binge-eating disorder
• Orthorexia nervosa

Eating disorders are most commonly diagnosed during adolescence and young adulthood, but also have the potential to develop both earlier in childhood and later in life. There are many factors that may contribute to the onset of an eating disorder, including social or cultural factors, genetics, biology, etc.

Due to the increased risk of suicide or medical complications, it is essential for individuals with eating disorders to receive intensive treatment as soon as possible. It is common for individuals with eating disorders to also experience other difficulties, such as depression, anxiety, or substance use. 

Treatment for eating disorders varies for each individual, but may include a combination of the following: 

• Individual, group, and/or family psychotherapy
• Medical care and monitoring
• Nutritional counselling
• Medications

Psychologists can help challenge unhealthy beliefs about food consumption and foster increased positive body and self-image. Psychologists can also help to manage any anxiety or depression symptoms that contribute to, or result from the eating disorder.
