Signs Your Child May Have an Eating Disorder: A Guide for Westchester Parents

As a parent, it's not always easy to tell the difference between typical childhood or teenage behavior and something more concerning. Changes in eating habits, mood, or body image can be part of growing up — but sometimes, they signal something deeper.

If you've found yourself wondering, "Is this normal, or should I be worried?" — you're not alone. As a Westchester-based eating disorder therapist, this is one of the most common questions I hear from local parents.

This post will walk you through some of the early and less obvious signs of eating disorders in children and teens, so you can better understand what to look for and when to seek support, including where to find help right here in Westchester.

It Doesn't Always Look Like What You Expect

Many parents assume eating disorders are obvious: dramatic weight loss, refusal to eat, or extreme behaviors.

But in reality, eating disorders often develop gradually and quietly, especially in children and adolescents.

You might begin to notice subtle shifts: a change in how your child eats, a growing focus on "health" or "clean eating," or small but persistent changes in mood. These signs can be easy to overlook or explain away, especially when they don't seem extreme, and especially in a community like Westchester, where wellness culture, sports performance, and academic pressure can sometimes mask early warning signs.

A Sign Most People Miss: The Growth Curve

Here's something even attentive parents, and sometimes pediatricians, overlook: a teen doesn't have to be thin to be seriously ill.

Children and adolescents are supposed to be growing. A teen who has always tracked along the 75th percentile and drifts down to the 40th hasn't just "leaned out" — they've lost significant ground against their own trajectory, even if their weight still looks "normal" or "healthy" on paper. The same is true for a teen who simply stops gaining during years when their body should be building: no dramatic loss, but a flat line where a rising one belongs.

This is why weight alone, and appearance especially, can't rule an eating disorder out. A teen can be medically compromised at any body size, and teens in larger bodies with eating disorders are often missed the longest, sometimes even praised for the very behaviors that are harming them. If your child's eating has changed and something feels off, their own growth history tells the real story, It's one of the first things we ask about, and your pediatrician's growth charts are one of the most valuable pieces of information you have.

Changes in Eating Patterns

One of the earliest signs is often a shift in how your child relates to food.

They may begin skipping meals, eating significantly less, or avoiding certain foods or entire food groups. Sometimes this shows up as rigid "rules," like not eating after a certain time, avoiding carbs, or insisting on only eating foods they consider "healthy."

You might also notice your child wanting to eat alone more often or becoming more private around food.

Because these behaviors are often framed as discipline or health-conscious choices, they can be difficult to recognize as potential warning signs.

In some cases, eating struggles may also involve significant food avoidance, sensory sensitivities, or anxiety around certain foods. For some children, these patterns may be related to Avoidant Restrictive Food Intake Disorder (ARFID), which can look different from more stereotypical eating disorder presentations.

Increased Focus on Body or Appearance

Another common shift is a growing preoccupation with body image.

Your child might start commenting more frequently on their body, comparing themselves to others, or expressing dissatisfaction with how they look. Sometimes these comments are subtle, phrases like "I feel gross" or "I need to be better about what I eat." Over time, though, they can signal a deeper struggle.

Even if it doesn't seem severe, an increasing focus on weight, shape, or appearance is worth paying attention to.

Changes in Mood or Behavior

Eating disorders don't just affect food — they often show up emotionally as well.

You may notice your child becoming more irritable, withdrawn, or anxious, particularly around meals or social situations involving food. Things they once enjoyed might no longer hold the same appeal, and there may be an increase in perfectionism or self-criticism.

Avoidance or Control Around Meals

You might observe resistance to family meals, a strong preference for preparing their own food, or discomfort eating in front of others. Meals may take longer, or your child may pick at their food rather than eat fully.

These patterns are often less about preference and more about anxiety, control or internal distress.

Changes in Energy, Focus, or Physical Well-Being

When a child isn't getting enough nourishment, it begins to affect their body and mind.

This might look like low energy, difficulty concentrating, dizziness, or changes in sleep. Feeling cold all the time, sweatshirts in warm weather, complaints about freezing hands, is a sign parents often notice in hindsight. For teens who menstruate, missed or stopped periods are a significant red flag, not a quirk of adolescence. And driven, compulsive exercise — distress when a workout is missed, movement that feels like a requirement rather than a choice — belongs on this list too.

These symptoms aren't always immediately connected to eating, but they can be important pieces of the larger picture and the physical ones are worth raising with your pediatrician directly.

Trust Your Gut (Even If Your Teen Says They're Fine)

One of the most important indicators isn't a specific behavior: it's your intuition.

Many parents describe having a sense that something isn't quite right, even if they can't fully explain it. It's common to second-guess that feeling or wonder if it's "serious enough" to act on.

And here's the piece that keeps too many parents waiting: your teen insisting they're fine is not reassurance. Teens with eating disorders almost always minimize and many genuinely can't see how serious things have become, because the illness itself distorts their perception. When your gut and your teen's self-report disagree, your gut deserves the benefit of the doubt.

You don't need certainty to seek support. If something feels off, it's worth paying attention.

What to Do If You're Concerned

If you're noticing some of these patterns, you don't have to figure it out on your own.

It can help to gently check in with your child, while also observing patterns over time rather than focusing on a single moment. Reaching out for professional guidance can also provide clarity and support for both you and your child.

One important exception to patience: if your child is losing weight, restricting more and more, or showing the physical signs above, don't wait for more data or a better conversation. Reach out now. Early treatment changes outcomes, and your teen doesn't need to agree that anything is wrong for help to begin.
