Anorexia nervosa is a life-threatening eating disorder and a serious mental illness. It causes severe weight loss. Show
Having an eating disorder is not about vanity. People with anorexia nervosa commonly have an unhealthy focus on food, weight or body shape. They have an intense fear of gaining weight, even though they are significantly underweight. When a person with anorexia nervosa restricts their eating, it is not a lifestyle choice. It is a sign of a complex condition that affects both their physical and mental health. Anorexia nervosa affects males and females of all ages, including children. It commonly begins in adolescence. Women who develop anorexia nervosa often severely restrict their diet and exercise compulsively. Men who have this condition may use steroids or exercise compulsively, and restrict their food intake, so they can develop a muscular, toned body. Models and athletes who participate in sports that place emphasis on body weight and shape (such as gymnasts, jockeys and dancers) might also be at increased risk of anorexia nervosa. In 2012, over 25,000 Australians had anorexia nervosa (over 18,000 females and over 7,000 males). Recognising the signs early and getting help can reduce the impact of anorexia nervosa and help with a full recovery. What causes anorexia nervosa?The causes of anorexia nervosa are different from person to person. People may have a genetic predisposition for the condition. Triggers for the development or re-emergence of the condition may include:
Traits such as perfectionism and obsessive-compulsive tendencies, and conditions such as anxiety and depression may put people at further risk of developing anorexia nervosa. Symptoms of anorexia nervosaAn awareness of the signs and symptoms of anorexia nervosa can help early detection. Treatment is more effective if it begins early, but you can start recovery at any stage of the disorder. Physical symptoms of anorexia nervosaPhysical signs and symptoms may include:

Diagnosis of anorexia nervosaIf you think you (or someone you know) might have anorexia nervosa, it is important that you see your doctor as soon as possible. The health risks associated with anorexia nervosa are severe and can be life threatening. The sooner you seek help, the sooner you can start to recover, and the more effective treatment can be. Other healthcare professionals (such as dieticians, psychologists or psychiatrists) can recognise this mental illness, but may not be able to give you a full physical check-up. This is why seeing your doctor is important. To diagnose anorexia nervosa, a doctor:
Eating disorders can be an aspect of a range of conditions. Your doctor will need to make sure that you are not losing weight because of another reason, such as an undiagnosed physical illness or another mental health condition. Types of anorexia nervosaThere are two types of anorexia nervosa. One type emphasises the restriction of food intake. The other type includes excessive food intake (binge eating) followed by purging, or purging after the consumption of normal portions, or small amounts of food. Purging may include self-induced vomiting, or the misuse of laxatives, diuretics or enemas. Restriction of food intakePeople with the ‘restricting’ subtype of anorexia nervosa tend to severely reduce their energy intake or restrict the type of food they will eat. The signs can be different in each person, but they might include:
Binge eating and purgingPeople with the ‘binge eating and purging’ subtype of anorexia nervosa have similar symptoms to the restricting type, but they also have behaviours that include:
This type of anorexia nervosa shares some similarities to bulimia nervosa. People with anorexia nervosa, however, tend to strongly emphasise weight control by restricting energy intake, rather than primarily through purging behaviours. In addition, people with this type of anorexia nervosa have a lower body weight; whereas people with bulimia nervosa tend to have fluctuating body weight closer to the healthy weight range for their age and height. Long-term risks of ongoing anorexia nervosaUntreated and ongoing anorexia nervosa can cause problems including:
Treatment of anorexia nervosaResearch is continuing into which treatment for anorexia nervosa might be most effective. There is no single treatment method that suits everyone. Evidence suggests that treatment will help most people to recover from the condition. Evidence also suggests that it is best to get treatment started as early as possible, and that using a team of professionals with expertise in different fields is the best approach. Once anorexia nervosa is diagnosed, your doctor will organise a team to help you on your way to recovery. This might include establishing a healthcare team of different professionals such as:
Treatment needs to address both physical and psychological health. Common approaches include:
The aims of treatment include:
Most people with anorexia nervosa are treated outside a hospital setting. However, if the condition is severe, temporary treatment in a hospital might be needed. Outpatient treatment and day programs can also be very helpful in supporting people as they make changes to behavioural, thinking and eating patterns. People with anorexia nervosa who have also experienced physical, emotional or sexual abuse are encouraged to seek help for the trauma they have experienced, as well as their eating disorder.
