Does your child have an unhealthy relationship with food? Eating disorders can affect children and young people and here we explain what they are and how to get help.

What is an eating disorder in children?

Eating disorders in children are serious conditions that affect both physical health and psychological well-being. If a child has had a problem with food for longer than around 3 months, it may be a sign of an eating disorder.

These disorders, such as anorexia, bulimia and binge eating disorder, can occur for a variety of reasons, including psychological factors, environmental influences and genetic predispositions. Eating disorders are often characterized by an unhealthy relationship with food and a distorted body image, which can lead to dangerous eating behaviours and an obsession with body weight and shape.

According to the Australian website Eating Disorders the latest data estimates that the number of people in Australia with an eating disorder aged over 5 years old is around 1.1 million, or approximately 4.45% of the population (Deloitte Access Economics, 2024, p.27)

What set our therapist apart was her genuine empathy and personal insight. Not only did she possess a deep understanding of neurodiversity, but she also shared personal experiences that resonated with us, creating an instant connection and fostering a sense of trust!

Early detection and treatment is crucial to prevent long-term consequences and support the child’s return to healthy eating habits and self-image. It is important that caregivers, parents and teachers are aware of the signs of eating disorders and approach the situation with understanding and readiness to seek professional help.

What are the signs of an eating disorder in children?

Signs of an eating disorder in children can include:

  • Changes in eating behaviour, such as avoiding meals or specific foods, eating in secret. Going to the toilet immediately after eating.
  • Extreme focus on weight and body, including frequently talking about being “too fat” or doing excessive exercise. Wearing only baggy clothes.
  • Weight changes, either weight loss or in some cases weight gain (in the case of binge eating).
  • Emotional changes, such as increased irritability, anxiety around meals or social withdrawal.
  • Physical symptoms, including fatigue, weakness, abdominal discomfort, or in girls, lack of menstruation.
  • Negative self-image and low self-esteem related to bodyimage. Following people on social media with a focus on body image.
  • Development of rituals around food and meals, such as cutting food into very small pieces.

Early detection and treatment is crucial to reduce the risk of long-term physical and psychological consequences. If you suspect that a child may have an eating disorder, it is important to seek professional help.

Common eating disorders in children

Common eating disorders in children include:

1. anorexia nervosa

Children with anorexia nervosa have an intense fear of weight gain and a distorted body image, leading to extremely restricted food intake and often excessive physical activity. This can result in dangerous weight loss and nutritional deficiencies.

2. bulimia nervosa

Bulimia nervosa is characterized by episodes of binge eating followed by behaviours to prevent weight gain, such as self-induced vomiting, laxative abuse or excessive exercise. Children with bulimia may experience shame and guilt around their eating behaviours.

3. binge eating disorder (binge eating syndrome)

This condition involves recurrent episodes of binge eating without subsequent attempts to ‘lose’ weight, as seen in bulimia. Children who binge eat consume large amounts of food in a short period of time and often feel a sense of loss of control during these episodes.

4. Avoidant/restrictive food intake disorder (ARFID)

Formerly known as selective eating disorder, ARFID involves a significant restriction in the types or amount of food ingested, not because of a concern about body weight or shape, but rather because of a lack of interest in food, or an aversion to certain textures or flavors. This can lead to nutritional deficiencies and weight loss.

These eating disorders can have serious physical and psychological consequences for children, and it is important to seek professional help at the first sign of any of these conditions. Treatment strategies vary depending on the specific eating disorder and the child’s individual needs, but may include nutritional counselling, psychotherapy and family therapy. Early intervention is essential to promote recovery and support the child’s health and well-being.

Treatment for eating disorders in children

Treatment for eating disorders in children is often an integrated and multidisciplinary process that aims to address both the physical and psychological factors. The main goal is to restore the child’s healthy eating behaviours, normalize weight, treat any psychological issues, and support the child and family through the recovery process. Here are some core components of the treatment:

1. Medical supervision

It is important to closely monitor the child’s physical health to manage any medical complications arising from the eating disorder.

2. Nutritional therapy

A registered dietician can provide nutritional therapy to help the child understand the importance of balanced nutrition and gradually restore a healthy eating pattern.

3. Psychotherapy

  • Individual therapy, such as cognitive behavioural therapy (CBT), can help the child identify and change the thought patterns and behaviours that contribute to the eating disorder.
  • Family-based therapy (FBT) is often effective for younger children and adolescents, with the family playing a central role in treatment, helping to monitor meals and support the child’s recovery.

4. Group therapy or support groups

These can offer children and young people additional support and understanding from others experiencing similar challenges.

5. Drug treatment

In some cases, medication, such as antidepressants, can be part of the treatment plan to manage concurrent depression or anxiety.

6. Education and self-help

Educating the child and family about eating disorders and how they are managed can be an important part of recovery. Self-help resources and coping strategies can also be included.

7. Long-term support and follow-up

Regular follow-up visits with the health care team are important to monitor recovery and prevent relapse.

The treatment plan should be individually tailored to the child’s age, specific needs and the family’s situation. Family involvement and support is crucial throughout the treatment process. Collaboration between healthcare providers, schools and other support systems can further strengthen treatment outcomes and the child’s well-being.
