Eating disorders

An eating disorder is characterised by obsessive thoughts about food and body weight. People with eating disorders may limit the amount of food they eat (anorexia nervosa), eat lots of food in a very small time and then purge (bulimia) or regularly eat too much (compulsive overeating).

Obsessive thoughts about food and body weight can change eating patterns (dieting, making excuses not to eat, avoidance of social situations involving food, going to the bathroom straight after meals), mood (feeling depressed, irritable or anxious), daily activities (not wanting to go out socially, exercising excessively, spending a lot of time talking about appearance or weight or looking in the mirror) and appearance (wearing baggy clothes, losing or gaining weight, greasy or dry hair and skin).

What are the signs?

The signs of an eating disorder include:

  • dramatic weight loss (anorexia)
  • dramatic weight gain/loss (bulimia or compulsive overeating)
  • obsession or preoccupation with food
  • refusing to eat
  • complaining of being overweight
  • overexercising
  • uncharacteristic eating patterns (e.g. eating at different times of the day or eating abnormal amounts given to them)

What are the causes?

There is no single cause for eating disorders. It is thought that a number of factors are involved to varying degrees in different people, including: genetic inheritance, personal and psychological factors related to adolescence or family issues and social factors such as media representation of body image.

It is estimated that approximately 2 in every 100 people will develop some kind of eating disorder at some time in their lives - that is, approximately 200,000 Australians. While anyone can have an eating disorder, more females than males tend to be affected, particular teenage women.

How are eating disorders treated?

Eating disorders can be treated successfully. As eating disorders effect the person physically and psychologically, it is usually most helpful to treat them with a team of professionals including psychiatrists, dieticians, psychologists, nurses and others.
