Eating Disorders in Children

As a concerned parent, you may have noticed certain things that have now led you to investigate eating disorders in children.

Could it be just a case of “fussy eating”, or something more sinister?

Eating disorders often fill young people with self-criticism and shame, which leads to a lot of secrecy about their symptoms. It can be very hard for parents or loved ones to notice eating disorders in children, but some of the signs to watch for include:

Physical: Unexplained, significant and/or sustained weight loss, or failure to gain weight as expected; brittle hair and nails; puffy cheeks, red eyes; constipation.

Behavioural: Frequent commenting on weight of self and others; skipping meals or making excuses for not eating; secretive exercising; long showers, increased use of the bathroom, using the bathroom right after meals; “clean eating”, and any diet that involves cutting out food groups, including vegetarianism, paleo, etc; increased interest in food preparation; cutting food into small pieces, eating slowly, hiding or throwing away food; searching “pro-eating disorder” websites, Pinterest and Instagram.

Psychological: Emotional changes such as moodiness, sadness, anger, crying, or seeming snappy; sudden or increased interest in exercise and health; withdrawal from friends and family; personality traits such as being driven, high achieving, independent, and detail oriented can make young people more vulnerable to developing an eating disorder.

It is important to remember that eating disorders can occur in both boys and girls, and can often cause other problems such as depression and anxiety.

There are three main eating disorders which affect children:

1. Anorexia Nervosa

Young people with anorexia nervosa purposefully eat less food than they need to maintain their weight. They have an intense fear of gaining weight, or “becoming fat”, and often see themselves as heavier than they are. Young people judge themselves excessively, and harshly, based on their weight. Anorexia has many short and long term health consequences, and is the most likely to be fatal of all mental disorders.

2. Bulimia Nervosa

Young people with bulimia engage in binge eating, where they eat very large amounts of food while feeling out of control. In a bid to prevent weight gain, they engage in “compensatory behaviours” to make up for the extra calories. Behaviours can include self-induced vomiting, excessive exercise, fasting and misuse of laxatives, among others. Again, self-worth is based largely on weight and shape. Bulimia is also disastrous for health, and can be potentially life-threatening.

3. Avoidant/Restrictive Food Intake Disorder (ARFID)

More severe than fussy eating, children with ARFID avoid food/s to the extent that they experience significant nutritional difficulties, failure to grow or gain weight, and sometimes rely on nasogastric tube feeding. This disorder is not associated with body image, and usually occurs in infancy and early childhood.eating disorders in children

What Should I Do?

If you do have any concerns, it is important to act. Eating disorders are notoriously difficult to treat, with adults who are treated often staying ill for 5-10 years. Many people will never seek help for their eating disorder, and may struggle with fear of food and low self-worth throughout their life.

Eating disorders in children and adolescents may cause long term physical complications due to the growth that occurs during these years. Illness can affect bone density and size, fertility and hormonal changes throughout life, as well as significantly impacting major organs.

The most important reason to act early is that research shows that we are most effective at treating eating disorders early, and much less effective once the eating disorder has been around for 3 years or more. Eating disorders are appearing in younger and younger children, and children who present for treatment have often been suffering with their disorder for 6-12 months before those around them notice the signs.

Treatment of Eating Disorders in Children

Due to the physical risks involved with eating disorders in children, it is important to link in with your GP. Your child will need regular medical monitoring while they regain weight, and recover from their eating disorder. They may also need a medical admission to hospital to support this.

The only evidence-based treatment for children with anorexia is family based treatment (FBT). Cognitive behaviour therapy and FBT are both promising approaches for children with bulimia. Families, particularly parents, are absolutely vital in the recovery from an eating disorder. In FBT, your therapist will give you the skills and the support to help your child eat and regain their life and vitality. Recovery from an eating disorder is often a difficult and tiring journey for the whole family, but with professional help recovery is possible!

A great resource for parents is the book “Help Your Teenager Beat an Eating Disorder” by James Lock and Daniel Le Grange. This can be found easiest online, or can be borrowed from me in our first session.
