What is an eating disorder?

Eating disorders are serious psychiatric disorders, and include:

  • anorexia (anorexia nervosa)
  • bulimia (bulimia nervosa)
  • binge-eating disorder (BED)
  • avoidant restrictive food intake disorder (ARFID)
  • other eating and feeding disorders (OSFED).

Eating disorders are diagnosed by a mental health professional such as a clinical psychologist or medical professional (for example a GP, psychiatrist or paediatrician).

Eating disorders are defined by disordered attitudes, thoughts and behaviours towards food, eating, weight or body shape, that impair an individual’s functioning and quality of life4.

If left untreated, eating disorders or disordered eating can have a seriously negative impact on all areas of your life. They can impact you physically and emotionally, and also affect your ability to study or work and to engage socially.

The impact of an eating disorder is often felt by the entire family and circle of support. They may lead to caregiver stress, loss of family income, disruption of family relationships and a high suicide risk.

Many people with eating disorders can look healthy but are actually very unwell. Anyone can experience an eating disorder or disordered eating - all genders, ages, races, ethnicities, body shapes and sizes, sexual orientation and socioeconomic statuses.

While genetics can play a role in the development of these illnesses, there may be other underlying factors, including:

  • depression
  • anxiety disorders
  • personality disorders
  • substance abuse problems.

Environmental factors, like social pressures and social media, can add to the development of an eating disorder.

Eating disorders or disordered eating can also arise to cope with stress and difficulties in your life. They may help as a distraction, a sense of accomplishment, to feel in control, or numb emotions. They can also form a part of a person’s sense of self.

For the LGBTQIA+ community, research has shown that adults and adolescents experience a greater incidence of eating disorders and disordered eating than their cisgender and/ or heterosexual peers.4

Eating Disorders are also overrepresented in neurodivergent people, including autism, attention deficit hyperactivity disorder (ADHD), intellectual disability, giftedness, and Tourette’s Syndrome.5

What should I do?

The signs and symptoms of an eating disorder or disordered eating can be missed. Even by close family and friends. A person with an eating disorder or disordered eating may experience shame, anxiety, embarrassment, isolation, secrecy, guilt or denial about their behaviours.

If you or someone you know has the signs and symptoms of an eating disorder or disordered eating, seek professional help. Sometimes thinking about accessing professional help or talking about this can be difficult.

  • Please consider learning more about eating disorders.
  • If you are approaching a loved one with any concerns, have the conversation in a safe and comfortable environment.
  • Be compassionate, non-judgemental, and respectful.

Where to get help

If you’re worried about your own eating habits, or those of someone you care about, there are many places you can get help and support. It is possible to make a full recovery from an eating disorder. Acting earlier on any concerns will help you or your loved one in recovery.

Your GP can help with an Eating Disorder Care Plan. This plan gives the support you need for recovery. On this plan you can access up to 40 psychological treatment services and up to 20 dietetic visits each year, subsidised by Medicare. Please note there may be a gap payment.

To find out if you’re eligible for an Eating Disorder Care Plan, please speak with your GP or medical professional.

Working with a clinical psychologist or mental health professional is also a critical step in healing. Find a mental health professional on HealthDirect.
