An eating disorder is a complex mental health issue characterised by disturbed eating behaviours, distorted beliefs, and extreme concerns about food, eating and body size, shape or weight.
Eating disorders can be associated with major medical complications which can affect the whole body. They are not a phase, a lifestyle choice or about vanity. No one would choose to have an eating disorder.
An eating disorder is characterised by distorted beliefs and behaviours around food, eating, and body image.
They are not a phase, a lifestyle choice or about vanity. No one would choose to have an eating disorder.
Anyone can develop an eating disorder, including all ages, genders, cultures and backgrounds. Eating disorders can affect people of all body types.
People living with eating disorders often experience other mental health issues, such as depression, anxiety disorders, substance use disorders, post-traumatic stress disorder, or personality disorders1.
Symptoms of eating disorders usually first appear in adolescence or early adulthood. Symptoms include2,3:
There can be serious complications associated with an eating disorder. They include problems with digestion, hormones, teeth, bone health, menstruation, heart and blood pressure. People can also die from the physical complications of an eating disorder.
Some of the most common types of eating disorder are summarised below4.
Many people have other eating issues and body image challenges which are not covered by these diagnoses. However, their mental health and quality of life can still be seriously impacted.
The causes of eating disorders are complex. Researchers believe a combination of genetic and biological factors, personality traits, and experiences affect the likelihood that someone will develop an eating disorder 5-7.
There are many societal and cultural factors that also contribute. People can be impacted by pressure from the media to look thin, toned or muscular, or to eat a certain way.
It’s estimated that around 4% of Australians experience an eating disorder each year8. Binge eating disorder is the most common type.
There are strategies that can help people manage the symptoms of eating disorders:
Treatment can help manage, reduce, or even eliminate the symptoms of eating disorders.
It’s a good idea to first talk to a GP. A GP can provide information and refer on to other health professionals or support services. They can also explore if there are any health conditions contributing to weight changes or appetite.
Treatment may need to involve different health professionals, like GPs, psychologists, specialist dietitians and other allied health professionals. This is because the best treatments will take a person’s physical, emotional and environmental needs into consideration, as well as their mental health needs.
Treatment options depend on age, the type of eating disorder and its severity. Different services might be available if any other mental or physical health issues are present. Treatment can include psychological therapies, outpatient programs, community programs, and support groups. A person may need inpatient stays at a hospital if there are physical health complications, or to focus on weight gain before getting support in the community.
Psychological therapies are often recommended for people with eating disorders. These are often intensive at the start, and may reduce in intensity over time. For adults, these include 9,10:
The family and friends of someone experiencing eating disorders need care and support too — it’s okay for family and friends to set boundaries, and to prioritise their own physical and mental health.
There are many other people out there who share similar experience, and many services designed to help carers of people with mental health issues. Check out our Guide for Families and Friends for more info.
Effective treatment and support is available, and a person who is experiencing an eating disorder can live a fulfilling life.
