Eating Disorders and Obesity in Children: A Guide for Parents from Pediatric Doctors

Nearly one in five children in the United States has obesity, and health visits for eating disorders in children under 17 more than doubled between 2018 and 2022. These two conditions — often seen as opposites — are actually deeply connected, and both are rising at a pace that demands attention from every parent in our community.

If you are raising children in Midwood or Flatbush, Brooklyn, you may already sense that something is shifting. The pressures children face around food, body image, and weight are more intense than ever. As pediatric doctors in Brooklyn, NY, the team at AllHealth Diagnostic and Treatment Center sees these challenges every week. This guide is written to help you recognize warning signs early, understand what the latest research says, and know exactly when and where to get help.

Trusted care from Pediatric Doctors, Brooklyn, NY.

Key Takeaways

• Childhood obesity and eating disorders are both rising, and they frequently occur together in the same child.
• BMI alone is not enough to diagnose an eating disorder — behavioral changes and family concerns matter just as much.
• Early intervention dramatically improves outcomes for both conditions.
• Weight-loss medications carry serious risks for children, especially those with disordered eating patterns.
• Comprehensive, family-centered care from experienced pediatric providers is the most effective approach.

Comprehending Childhood Obesity: What the Numbers Tell Us

According to national survey data, approximately 19.3% of U.S. children and adolescents aged 2 to 19 have obesity, and 6.1% have severe obesity. A 2025 study found that severe obesity in U.S. children has more than tripled since 2008, with the highest rates seen in adolescents and Black children.

These are not abstract statistics. They represent real children in our Brooklyn neighborhoods — kids who may be struggling with their energy, their confidence, and their long-term health.

What Causes Childhood Obesity?

Obesity in children is rarely caused by one single factor. A 2026 analysis of national child health survey data identified three overlapping categories of risk:

Behavioral factors:

• Excessive screen time
• Low physical activity
• Poor sleep habits
• Frequent consumption of ultra-processed foods

Household factors:

• Food insecurity
• Parental stress and mental health
• Limited access to nutritious foods

Community factors:

• Neighborhood safety (affects outdoor play)
• Proximity to fast food versus fresh produce
• School nutrition environments

Comprehending these layers is critical because it means that blaming the child — or the parent — is both unfair and unhelpful. Effective care must address the full picture.

Health Consequences of Childhood Obesity

Obesity in childhood is associated with a wide range of medical complications, including:

System Affected	Potential Conditions
Cardiovascular	High blood pressure, high cholesterol
Metabolic	Type 2 diabetes, insulin resistance
Orthopedic	Joint pain, flat feet, gait problems
Respiratory	Sleep apnea, asthma
Psychological	Depression, anxiety, low self-esteem
Gastrointestinal	Fatty liver disease, acid reflux

Children with obesity are also significantly more likely to develop eating disorders. A Canadian study found that adolescents with obesity had eating disorder rates of 9.3% in males and 20.2% in females — compared to 2.1% and 8.4% respectively in healthy-weight peers.

Recognizing Eating Disorders in Children: More Than Just Weight

In January 2026, NHS England issued important new guidance advising healthcare professionals not to rely solely on BMI when diagnosing eating disorders in children. This was a landmark shift. A child can have a normal or even high BMI and still be suffering from a serious eating disorder. Behavioral changes and family concerns must carry equal weight in any clinical assessment.

Common Eating Disorders in Children and Adolescents

Anorexia Nervosa Characterized by severe restriction of food intake, intense fear of weight gain, and a distorted body image. Children with anorexia may appear to eat normally in front of others but secretly restrict.

Bulimia Nervosa Involves cycles of binge eating followed by purging behaviors such as vomiting, excessive exercise, or laxative use. This disorder is often hidden and can be present in children of any weight.

Binge Eating Disorder (BED) The most common eating disorder in the U.S. Children with BED eat large amounts of food in a short time, often in secret, and feel significant shame or guilt afterward. BED is strongly associated with obesity.

Avoidant/Restrictive Food Intake Disorder (ARFID) ARFID is not driven by body image concerns but by extreme sensory sensitivity, fear of choking, or a very limited range of accepted foods. It is particularly common in children with autism spectrum disorder or developmental differences.

Warning Signs Every Parent Should Know

Physical signs:

• Unexplained weight loss or gain
• Fatigue, dizziness, or fainting
• Hair thinning or loss
• Dental erosion (a sign of purging)
• Frequent stomach complaints

Behavioral signs:

• Avoiding family meals or making excuses not to eat
• Eating very quickly and then disappearing to the bathroom
• Wearing baggy clothes to hide body changes
• Excessive focus on food, calories, or dieting
• Mood changes after meals

Emotional signs:

• Intense fear of gaining weight
• Negative self-talk about their body
• Withdrawal from friends and activities they used to enjoy

If you notice several of these signs together, do not wait. Early intervention is one of the strongest predictors of recovery.

The Growing Risk of Weight-Loss Medications in Children

As of May 2026, healthcare providers are raising serious alarms about the use of GLP-1 weight-loss drugs in individuals with eating disorders. Children who have disordered eating patterns may be at particular risk if these medications are prescribed without a thorough psychological evaluation. Any weight management plan for a child must include a mental health screening before any medication is considered.

Our pediatric doctors in Brooklyn, NY at AllHealth DTC follow evidence-based protocols that prioritize safety and whole-child wellness above any single treatment approach.

How Pediatric Doctors, Brooklyn, NY Can Help Your Child

Effective care for both obesity and eating disorders requires a team. No single specialist can address all the dimensions of these conditions. At AllHealth Diagnostic and Treatment Center, we offer a coordinated approach that brings together multiple disciplines under one roof.

Pediatric Primary Care

Your child’s pediatrician is the starting point. Regular well-child visits allow us to track growth trends over time, identify early warning signs, and coordinate referrals.

During a well-child visit, your pediatric doctor will:

• Review your child’s growth chart and BMI trajectory
• Screen for behavioral and emotional concerns
• Ask about eating habits, sleep, and physical activity
• Discuss family history of metabolic or mental health conditions

If you are concerned about your child’s eating patterns or weight, do not hesitate to bring it up directly. There is no concern too small to mention.

Endocrinology for Metabolic Concerns

Some children with obesity have underlying hormonal conditions — such as hypothyroidism, polycystic ovary syndrome (in adolescent girls), or insulin resistance — that contribute to weight gain. Our endocrinology team in Brooklyn can evaluate these factors and develop a medically appropriate treatment plan.

Psychological and Developmental Evaluations

Eating disorders are mental health conditions. A proper psychological evaluation is essential for accurate diagnosis and treatment planning. Our psychological testing services in Brooklyn can help identify co-occurring conditions such as anxiety, depression, ADHD, or autism spectrum disorder that may be driving disordered eating behaviors.

Pediatric Physical Therapy

For children with obesity-related orthopedic issues — such as joint pain, poor posture, or difficulty with physical activity — pediatric physical therapy in Brooklyn can make movement more comfortable and enjoyable. Building a positive relationship with physical activity is a critical part of long-term weight management.

Speech Therapy and ABA Therapy

Children with ARFID or extreme food selectivity often benefit from pediatric speech therapy, which addresses the oral motor and sensory components of eating. For children with autism or developmental differences, ABA therapy has been shown to help expand food acceptance and reduce mealtime anxiety.

Gastroenterology

Children with obesity frequently experience gastrointestinal symptoms such as acid reflux, constipation, or fatty liver disease. Our gastroenterology team in Brooklyn can evaluate and treat these conditions as part of a comprehensive care plan.

Practical Steps Parents Can Take at Home

While professional care is essential, parents play a central role in their child’s recovery and health. Here are evidence-informed strategies you can start today:

Build a positive food environment:

• Offer a variety of foods without labeling any as “bad” or “forbidden”
• Eat meals together as a family when possible
• Avoid using food as a reward or punishment

Support healthy movement:

• Focus on activities your child enjoys, not calorie burning
• Limit recreational screen time to encourage active play
• Walk or bike together as a family

Protect your child’s body image:

• Avoid commenting on your child’s weight or appearance
• Challenge negative body talk when you hear it
• Celebrate what bodies can do, not how they look

Watch your own language:

• Children absorb parental attitudes about food and weight
• Model balanced eating without dieting language
• Seek support for your own food-related stress if needed

Know when to ask for help:

• Trust your instincts as a parent
• If something feels wrong, schedule an appointment
• Early intervention is always better than waiting

FAQs:

Can a child have both obesity and an eating disorder at the same time?

Yes, and this is more common than many parents realize. Binge eating disorder, in particular, is strongly associated with obesity. A child may be gaining weight while simultaneously engaging in disordered eating behaviors like secret bingeing, emotional eating, or extreme restriction followed by overeating. This is why any weight management plan must include a mental health screening. Our pediatric doctors in Brooklyn, NY always evaluate the full picture before recommending treatment.

At what age can eating disorders appear in children?

Eating disorders can appear as early as age 5 or 6, though they become more common during adolescence. ARFID (Avoidant/Restrictive Food Intake Disorder) is frequently identified in younger children, while anorexia and bulimia tend to emerge in the preteen and teenage years. Early signs in young children include extreme food refusal, gagging at certain textures, or significant anxiety around mealtimes. If you notice these patterns, speak with your child’s pediatrician promptly.

Should I put my child on a diet if they have obesity?

Restrictive dieting is generally not recommended for children and can actually increase the risk of developing an eating disorder. Instead, the focus should be on building healthy habits for the whole family — balanced nutrition, enjoyable physical activity, adequate sleep, and emotional wellbeing. A pediatric doctor or registered dietitian can help design an age-appropriate plan that supports healthy growth without creating a harmful relationship with food.

How do I talk to my child about their weight without causing harm?

Focus on health, energy, and how the body feels — not on appearance or numbers. Avoid words like “fat,” “diet,” or “calories” with young children. Instead, talk about eating foods that give us energy, moving our bodies because it feels good, and taking care of ourselves. If your child brings up their own concerns about their weight or body, listen without judgment and consider scheduling a visit with a pediatric professional who can guide the conversation in a safe and supportive way.
