Eating disorders in children are more common than many parents realize. They are not just about fussy eating or skipping a few meals now and then. Instead, they are serious mental health conditions that can affect a child’s body, mind, and emotions all at once. These disorders often begin quietly, with small changes in eating habits, and can quickly grow into dangerous health problems if not addressed early.

  • Some children may suddenly refuse foods they once enjoyed.
  • Others might become extremely anxious during mealtimes.
  • Many children might hide how much they’re eating, or secretly avoid food altogether.
  • Physical signs like tiredness, weight changes, or slow growth might also appear without clear explanation.

Narratively, picture a child who used to enjoy sitting at the family table but now insists on eating alone, avoids school lunch, and becomes upset when asked why. This could be more than just a phase. Understanding these early changes can help parents spot problems sooner and take the right steps before serious harm is done.


To understand eating disorders in children, it’s important to know that these are not just behavioral problems. They are serious mental health conditions where children struggle with fear, anxiety, and confusion about food and their bodies. The impact of these disorders can lead to both physical health problems and emotional distress.

Parents should watch for:

  • Ongoing food avoidance or extreme pickiness.
  • Anxiety or fear during mealtimes.
  • Sudden obsession with “healthy” eating or weight.
  • Unexplained weight loss or lack of growth.
  • Secretive eating or skipping meals without clear reasons.

Narratively, imagine a child who keeps saying certain foods make them “feel weird” or “unsafe,” even though they loved those foods before. They may start refusing meals without explaining why, leaving parents confused and concerned. This situation could indicate the start of an eating disorders in children.


When parents ask what is the new eating disorder for kids, the answer is ARFID (Avoidant/Restrictive Food Intake Disorder). Unlike other eating disorders focused on body image or weight, ARFID is caused by sensory sensitivities or fear-based food avoidance.

Key signs of ARFID:

  • Extreme pickiness, much more severe than typical childhood selective eating.
  • Avoidance based on food texture, color, or smell.
  • Fear of choking, vomiting, or feeling sick after eating.
  • Weight loss or poor growth due to restricted food intake.
  • Mealtime anxiety and constant refusal to try new foods.

Narratively, think about a child who will only eat plain white bread or a specific brand of cereal, refusing everything else even when hungry. They may panic if presented with different foods, leading to significant weight loss. Recognizing ARFID early can prevent dangerous health complications.


Understanding what are 6 eating disorders helps parents realize there are more disorders than just anorexia or bulimia.

Here are the 6 main eating disorders:

  1. Anorexia Nervosa – Refusing to eat due to fear of gaining weight.
  2. Bulimia Nervosa – Eating large amounts of food, then purging through vomiting or laxatives.
  3. Binge Eating Disorder – Eating large amounts of food without purging, leading to weight gain and shame.
  4. ARFID (Avoidant/Restrictive Food Intake Disorder) – Extreme food avoidance unrelated to body image.
  5. Pica – Eating non-food items like dirt, paper, or soap.
  6. Rumination Disorder – Regurgitating, re-chewing, and re-swallowing food repeatedly.

Narratively, while anorexia and bulimia are widely known, disorders like ARFID or Pica are less obvious yet just as dangerous. A child refusing all but a few foods, or eating inedible items like chalk, needs immediate medical attention.


When asking which eating disorder is probably the most common, the answer is Binge Eating Disorder. This disorder often goes unnoticed because it does not involve visible weight loss like anorexia.

  • ARFID – Starts at younger ages but can persist into adolescence.
  • Pica – Typically seen in younger children.
  • Rumination Disorder – Appears in early childhood but may persist without treatment.

Narratively, teens may develop anorexia or bulimia due to peer pressure or body image issues, while younger children might face ARFID due to fear of certain foods. Recognizing which disorders can affect each age group is key to early intervention.
