Eating disorders

Over 1 million Australians have an eating disorder. Here’s how to spot the signs and where to turn to for help.

This article is of a general nature only. You should always seek medical advice if you are worried about someone or are experiencing signs or symptoms of an eating disorder.

Eating disorders

If you have obsessive thoughts and behaviors about food and weight, you’re not alone. It’s estimated that over 1 million Australians are affected by eating disorders.

Eating disorders are a mental health condition that can affect anyone, regardless of age, gender, shape or size. If you think you’re experiencing symptoms of an eating disorder, speak to your GP. They’ll be able to offer you support and advise on the best next steps for your treatment. 

Symptoms and warning signs of an eating disorder

People with eating disorders can experience a wide range of symptoms and there is no ‘one size fits all’ when it comes to this mental health condition.

However, some warning signs could include weight fluctuations (gaining or losing), preoccupation with body appearance or weight, increased mood changes and irritability, sensitivity to cold, social withdrawal or obsessive rituals around food and food preparation. You might also notice an increased interest in preparing food for others, frequent excuses not to eat or a tendency to eat in secret, away from social situations.

If you have an eating disorder you might notice that you struggle to think rationally or concentrate. You might also experience anxiety or depression symptoms.

If you notice any of these warning signs in yourself or in a loved one, speak to your GP immediately. They will be able to advise on next steps and offer support.

Types of eating disorders

Some of the main types of eating disorders include: 

Anorexia nervosa

Restricted eating that results in weight loss, and fear of gaining weight. 

Bulimia nervosa

Involves periods of binge eating unhealthy foods, followed by attempts to compensate by over-exercising, vomiting, or strict dieting.

Binge eating disorder

Recurring periods of binge eating followed by feelings of guilt, disgust and depression.

Other specified feeding and eating disorders (OSFED)

Eating behaviours that cause distress that aren’t categorised in the above three.

Even if you don’t fit into any of these categories it’s important to seek help if you are struggling with obsessive or negative thoughts about food or your body, or if you’re feeling anxious or overwhelmed. 

What causes an eating disorder? 

There is no one single cause of an eating disorder. Social, psychological and biological factors all play a part and the root cause is unique to each person.

The most important thing to remember is that your eating disorder is not your fault, it is a mental health condition that can affect anybody. 

Social factors

These can include the media and representations of the ‘ideal body’, pressure to succeed, our cultural tendency to judge people on appearance or activities that encourage a certain body shape or weight e.g. ballet, modelling or gymnastics.

Major life changes

Changes such as relationship breakdowns, pregnancy, the death of a loved one, moving to a new city or becoming a new parent can contribute to the onset of an eating disorder.

Life stressors

Fears of the responsibilities of adulthood, communication issues with friends or family or long held beliefs about the relationship between love and achievement along with many others can all accumulate to trigger an eating disorder.

Biological factors

Physical changes during adolescence or growing up as part of a family unit that are overly focused on body image, food or appearance can contribute to the onset of an eating disorder.

Psychological factors

Issues such as low self-esteem, negative body image, anxiety, depression, obsessive thinking and difficulty expressing emotion can manifest as an eating disorder.

There is also some evidence to suggest that eating disorders could have a genetic basis, although the biological causes are not well understood.

Treatment of eating disorders

If you suspect that you might have an eating disorder, it’s important to reach out and seek help, however hard that might be. Whilst recovery can be slow, with the right help and support it is possible to manage your eating disorder and even recover completely.

It’s normal to feel stressed, nervous, embarrassed, anxious or even ashamed when it comes to seeking treatment for an eating disorder. You may be in denial about your issue or feel that you have the disorder under control on your own, even when you don’t.

Remember, getting treatment as early as possible can reduce the severity and impact of an eating disorder so seek help as soon as you notice any warning signs.

Your doctor can help you set up a personalised treatment plan. Everyone is different, and what works for one person may not work for someone else, even if they have the same type of eating disorder. There are several types of effective treatment that are supported by evidence, and most people will need to try a combination of things. It’s usually recommended to get support from a team of health professionals such as a dietitian, social worker, dentist, psychologist, psychiatrist or others, depending on your individual needs. At some points, you may need extra support or more intensive treatment, and at other times you may need less. This is a normal part of recovery.

Where to get help

The best place to start is by speaking to your GP or health practitioner. They will be able to assess your individual situation and recommend the best next steps for your recovery.
