This page defines anorexia nervosa and provides information on warning signs, the physical effects of the illness, and treatment and recovery options.

What is anorexia nervosa?

Anorexia nervosa is a psychological illness that has devastating physical consequences. It is characterised by low body weight and body image distortion with an obsessive fear of gaining weight, which manifests itself through depriving the body of food. It often coincides with increased levels of exercise.

There are two main sub-types of anorexia:

Restricting type — this is the most commonly known type of anorexia nervosa, whereby a person severely restricts their food intake. Restriction may take many forms (e.g. maintaining very low calorie count, restricting types of food eaten, eating only one meal a day) and may follow obsessive and rigid rules (e.g. only eating food of one colour).

Binge-eating or purging type — less recognised, this type of anorexia nervosa forms when a person restricts their intake as above, but also has regularly engaged in binge-eating or purging behaviour (e.g. self-induced vomiting, over-exercise, misuse of laxatives, diuretics or enemas).

Who gets anorexia nervosa?

There is no single cause of anorexia but there are risk factors that increase the likelihood of anorexia developing. These can be cultural, biological or psychological.

Anorexia nervosa usually develops during adolescence and generally has an earlier age of onset than bulimia nervosa and binge eating disorder (the latter are often developed during late adolescence or early adulthood). However, like all eating disorders, anorexia can develop at any age or stage of life for both males and females. It is a myth that only adolescent girls experience anorexia.

RECOVERY STORIES

My anger at anorexia

I get very angry and upset about my eating disorder: what it did to me, what it took from me. It put so much strain on my body and brain and I lost so much time and freedom, having to spend so long in hospital.

Recovery and treatment

It is possible to recover from anorexia, even if you have been living with the illness for many years. The first step towards recovery is to ask for help. With the right team supporting you and a high level of commitment, you can recover from anorexia.

Anorexia is an incredibly serious mental illness and had the highest mortality rate of any psychiatric illness. Extreme food restriction can lead to starvation, malnutrition and a dangerously low body weight — all of which are synonymous with a host of health problems. However, complete recovery from anorexia is possible and early treatment leads to the greatest success.

Eating Disorders Victoria has put together a step-by-step guide take if you are concerned that you may be experiencing anorexia. It also covers how to talk to family or friends about what you’re going through. Remember that you have the best chance of success if you include people you trust on your journey.
