Eating disorders in boys

What are the different types of eating disorders in boys?

Eating disorders affect how a child thinks and behaves toward food. For example, a boy may see himself as overweight, even though he is actually normal weight or underweight. Or a boy might see himself as too skinny or not muscular enough and obsess over having a more muscular body.

The most common types of eating disorders in boys include:

• Anorexia nervosa - Children with anorexia have a strong desire to avoid gaining weight. This can lead them to lose unhealthy amounts of weight. They are often extremely underweight (very thin) for their age but can be in or above their healthy weight range as well.
• Bulimia nervosa - Children with bulimia tend to eat large amounts of food at once (called binge eating). Then they do something to avoid gaining weight, such as making themselves vomit, taking laxatives or exercising excessively. They can be average weight, underweight or even overweight for their age.
• Avoidant and restrictive food intake disorder (ARFID) - Children with ARFID struggle to eat for reasons that are unrelated to weight gain or body image. They may eat only a few specific foods and refuse all others. This may be based on texture, taste, a fear of choking or vomiting, or other fears or struggles. Boys with ARFID may lack the nutrients they need to grow and be active.

How are eating disorders in boys diagnosed?

Only medical professionals can properly diagnose an eating disorder. They do this by gathering information about your child’s health and behavior through interviews, tests and exams.

To determine if your son has an eating disorder, we may look at their blood count and organ function, to see if they need medical care to restore the right balance of nutrients. We will ask you and your child about his eating and exercise habits, as well as certain social behaviors. Boys with eating disorders may withdraw from friends or do poorly in school, because they’re hiding or struggling with their disorder.

What causes eating disorders in boys?

Many factors play a role in children developing eating disorders. These factors include genetics, stress, experiences, and social and cultural pressures to have a particular weight or appearance.

For example, many boys will feel pressure to be lean and muscular. This can lead to unhealthy eating habits and an obsession with changing their bodies.

Children of all different backgrounds, ethnicities, religions and cultures can develop eating disorders. They do not choose to have an eating disorder, nor do they develop one because of parenting choices.
