Eating Disorders

What are eating disorders?

Eating disorders are a range of conditions involving an obsession with food, weight and appearance. This obsession negatively affects people's health, relationships and day-to-day living.  To be diagnosed with an eating disorder, a person must have both disordered eating and psychological disturbance.

About 90 per cent of people diagnosed with eating disorders are girls and women; however, boys and men are increasingly being diagnosed. Eating disorders typically begin during adolescence.

Are there different types of eating disorders?

The DSM IV recognizes two types of eating disorders:

  •  anorexia nervosa: People with anorexia have an intense and irrational fear of gaining weight and having body fat. They are obsessed with being thin. They may believe they are fat, even when they are well below the normal weight for their height and age.
  •  ​bulimia: People with bulimia go through cycles of bingeing and purging. Bingeing involves eating large amounts of food quickly. This makes people feel physically ill and anxious about gaining weight. Then they will purge, which can involve vomiting, depriving themselves of food, over exercising or using laxatives and diuretics.

The DSM 5 (published in May, 2013) recognizes a third type:

  • binge eating disorder (BED): People with binge eating disorder overeat compulsively, consuming huge amounts of food, often all at once. Like the other disorders, people with BED often feel out of control and powerless to stop the behaviour.

What are the causes of eating disorders?​

Eating disorders appear to result from multiple factors including: cultural, social, family and emotional pressures, personality disorders, and genetics and biological factors. Some research has shown a connection between child sexual abuse and subsequent development of eating disorders.

What is the treatment for eating disorders?​

The first step in recovery is realizing that we have behaviours related to food and weight that are hurting us. Once that realization has been made, there are a variety of ways in which help can be found or offered to those suffering from an eating disorder.

Treatment pproaches include:

  • psychoeducation
  • nutritional counselling
  • psychotherapy including cognitive behavioural therapy (CBT) and interpersonal therapy (IPT)
  • pharmacotherapy (SSRIs have been found to have some effect in treating bulimia but not anorexia).
