GLP-1 Medications for Children and Teens
December 26, 2025
GLP-1 medications are coming up more often in pediatric care, and for many parents, that raises real questions. Are they safe? When are they used? How do they affect growth, nutrition, and a child’s relationship with food?
I recently spoke with pediatrician Dr. Chrissie Ott on my podcast to explore GLP-1 medications for children and teens through a compassionate, science-informed lens. This isn’t about promoting or rejecting medication. It’s about understanding when and how it may fit into care, while always protecting a child’s emotional and physical well-being.
What GLP-1 Medications Actually Do
GLP-1 medications mimic a hormone produced in the gut that helps regulate appetite. It slows stomach emptying, increasing fullness, and influences brain pathways involved in hunger and food-seeking.
For some children, these pathways are simply more active than for others. Appetite regulation isn’t just willpower, it’s deeply influenced by biology, which is often obvious the moment you compare siblings raised in the very same home.
Why Lifestyle Changes Aren’t Always Enough
Many families are still told that body size comes down to “eat less, move more.” That message is common, and still harmful.
Children’s bodies are shaped by genetics, hormonal signaling, metabolism, emotional health, and environment. Nutrition, movement, and emotional support matter for every child, but for some, lifestyle strategies alone aren’t enough to counteract powerful biological drivers of hunger and weight gain.
That’s not a failure. It’s information.
When GLP-1 Medications May Be Considered
These medications are not a first-line approach and aren’t appropriate for most children.
They may be considered when a child has had a persistently high BMI over time, lifestyle interventions haven’t been sufficient, there are physical or emotional health concerns, and the child understands and agrees to treatment.
Children deserve to be involved in decisions about their own bodies.
They’re generally not appropriate for children with a family history of certain thyroid cancers, a history of pancreatitis, those seeking small or cosmetic changes, or children at high risk for restrictive eating disorders.
These medications are not meant for body “optimization.”
Protecting Nutrition, Growth, and Development
A common concern is whether appetite suppression could interfere with growth.
This is where careful monitoring matters: prioritizing protein and fiber, choosing nutrient-dense foods, protecting lean muscle mass, and watching closely for under-fueling.
The goal is regulated appetite, never deprivation.
What Parents Should Take Away
You do not have to choose between helping your child’s health and protecting their emotional well-being. You can do both.
GLP-1 medications aren’t right for every child, but for some families, they can be one supportive tool among many, used thoughtfully, ethically, and with full attention to your child’s whole experience.

Medication or Not, the Foundation Is the Same
Whether or not medication is ever part of your child’s picture, the daily habits underneath it, sleep, food, feeding, eating, movement, screens, self-love, and family culture, are what determine how your child feels day to day.
That foundation is exactly what I help families build in my private nutrition practice.
Together, we look at your child’s growth pattern, eating habits, and home environment, and build a plan around the eight areas that actually move the needle: sleep, food, feeding, eating, movement, screens, self-love, and family culture.
No diets. No rules that backfire. Just the right habits, in the right order, for your child.
What It Looks Like to Work Together
Step 1: A deep dive intake. We review your child’s growth pattern, eating habits, lifestyle, medical history, and family environment together.
Step 2: A personalized plan. We create a clear, realistic plan built around your child and your family, not a generic list of rules.
Step 3: Ongoing coaching and support. 12 regular sessions over 3 months, direct support between visits, and adjustments as your child grows and changes. You are not left to figure this out alone.
“All of your helpful thinking and education has made my son wise and thoughtful about nutrition.”
Frequently Asked Questions
Are GLP-1 medications safe for children?
They may be appropriate for a small subset of children under close medical supervision. This is a decision to make with your child’s medical team, not on your own, and not as a first step.
Will GLP-1 medication affect my child’s growth?
It can, if appetite suppression isn’t carefully monitored. Working with a pediatric dietitian alongside your prescribing doctor helps protect nutrition, growth, and lean muscle mass.
Do I still need to focus on habits if my child is on medication?
Yes. Medication addresses biology, not the daily environment your child lives in. Sleep, structured meals, joyful movement, and a supportive family culture matter just as much, with or without medication.
