Understanding the Root Causes of Pediatric Health Issues
Updated: Sep 13
Your child gets sick every three weeks. Or the stomach aches come back every Sunday night. Or the eczema clears with the cream and then returns the moment you stop using it. You've done the visits. You've done the rounds of antibiotics. You've done the cream, the inhaler, the Miralax. And every time you think you've finally got it, it comes back.
You've done everything right. You've shown up, you've pushed for answers, you've tried the strategies. And something is still being missed. You've been told he'll grow out of it. You've been told this is just what kids do. But you are the one living it, and you're still up at night looking.
Symptoms that keep coming back are not a sign that you failed. They are information. Usually it means whatever was causing them was never actually addressed. It was quieted.
What do parents ask me most about this?
Short answers first. The full reasoning is below.
Why do the same symptoms keep coming back?
Because they are information, not a sign that you failed. Usually it means whatever was causing them is still there, and only the symptom was treated.
Does treating the symptom mean we did it wrong?
No. If your child cannot breathe, they need the inhaler. Symptom relief matters. The question is whether anyone also went looking for what set it off.
Where do you start looking?
Not with a fancy test. With the Foundational Five: sleep, airway, nutrition, hydration and movement.
What are the quiet signs parents miss?
The ones that do not look like illness. A child may not be able to tell you their stomach hurts, so the hurt shows up as a hard afternoon, a sleepless week, or a short fuse.
Could it be something in our house?
Sometimes the answer is not inside the child. Water damage or mold, heavy fragrance, cleaning products and dust are all worth looking at, though I put them after sleep and food.
Symptoms are the signal, not the cause
A symptom is your child's body telling you something is off.
Treating only the symptom is like taking the battery out of a smoke alarm. The noise stops. The problem doesn't. Functional medicine is simply the habit of asking why the alarm went off, and then going to look.
To be clear, that doesn't mean the symptom relief was wrong. If your child can't breathe, they need the inhaler. If they're impacted, they need help clearing. I work in conjunction with your pediatrician, therapists, and specialists, not as a replacement for them. My question is different: what is making this keep happening?
It isn't only your child
Parents often tell me they feel like they must be doing something wrong, because it seems like their kid is sick more than everybody else's. It's worth knowing that the broader picture has been shifting. When researchers looked at national data on American children, chronic conditions and reported symptoms have been rising over the last two decades.1
I'm not saying that to frighten you. I'm saying it because parents are often carrying this alone and privately blaming themselves. There is no judgment here in looking for more answers.
Where I actually go looking
I don't start with a fancy test. I start with the Foundational Five: sleep, airway, nutrition, hydration and movement. If those aren't in place, none of the rest matters. That order is not negotiable in my practice, and it's why I don't lead with testing.
Sleep and how they breathe at night
Sleep is where the immune system does a lot of its work. Researchers describe sleep and immunity as a two-way conversation: poor sleep changes immune signaling, and immune activation changes sleep.2 So the kid who catches everything and the kid who sleeps badly are very often the same. My sleep page goes deeper on this.
Then there's the airway, which gets missed constantly. Snoring, mouth breathing, night sweats, teeth grinding, a head tipped way back on the pillow. Sleep-disordered breathing overlaps so closely with attention and behavior problems that clinicians have written about children whose focus and behavior traced back to how they were breathing at night.3 If your child snores with gasping or pauses in breathing, get that evaluated now.
The gut
If the gut can't handle whatever else is going on, you're going to get nowhere. That's why I work in phases and start there. Your child's gut, immune system, and brain are closely linked. When the gut is out of balance, the ripples show up everywhere else.
Constipation is far more common in children than most families realize. When researchers pooled the studies, functional defecation disorders showed up in a substantial share of children worldwide.4 And a constipated child is carrying a low-grade physical misery all day that they usually can't describe. It comes out as a hard afternoon instead.
What a child eats also shapes the community of microbes living in the gut, and that community influences the signals traveling to the brain.5 That's not a slogan. That's plumbing and chemistry.
Food and blood sugar
Food is medicine, and it does most of the heavy lifting in my plans. When researchers pooled studies of children and teens, better overall diet quality tracked with better mental health, and poorer diet quality with worse.6 Practically, that means protein and fat at breakfast rather than juice and cereal, and a serious look at artificial dyes, hidden sugars, seed oils, and heavily processed food.
Blood sugar swings are their own driver. A mostly-carb breakfast sends a child up and then straight back down, and the crash lands in the middle of the school day. Some families see a difference within a week just from changing what's on the plate at 7 am.
Water and movement
Under-drinking shows up as constipation, headaches, afternoon crashes, and shorter tempers. Water in the morning, water in the backpack, water before screens. And daily movement, ideally outside, helps sleep, mood, the gut, and the nervous system all at once. Both of these are free, and I ask about them before I ask about anything you'd have to buy.
The home itself
Sometimes the answer isn't inside the child. Water damage or mold in the house, heavy fragrance, cleaning products, dust and pests, and the plastics and pesticide residue that come in with food all add to the load a body is carrying. I go through this with families because it's often cheaper to change than anything else on the list.
The quiet signs parents overlook
The loud symptoms get attention. These are the ones that usually don't, and they are often where the real story is:
Eczema, rough patches, or skin that flares and settles for no clear reason
Poop that's hard, infrequent, or huge, or a child who hides to go
Picky eating that keeps getting narrower instead of wider
Waking at nearly the same time every night
Dark circles, a constantly stuffy nose, or a mouth that's always open
Toilet training that is still hard well past when you expected
Mood that flips fast, especially before meals or late afternoon
A skill that stalled or went backward
A child may not be able to tell you that their stomach hurts. So the hurt shows up as a hard afternoon, a sleepless week, a food refusal, a skill that stalls. I've written more about why symptoms keep coming back if you want the longer version.
My order of operations
This is the part that makes the difference, and it's the part most people get backward.
First, the Foundational Five. Sleep, airway, nutrition, hydration, movement. Give them real time.
Second, ordinary labs. Iron and ferritin, a complete blood count, a basic metabolic panel with a fasting glucose. Cheap, often covered, and genuinely informative.
Third, functional testing when the picture calls for it. Stool and gut microbiome testing, organic acids, food sensitivity testing.
Fourth, and only fourth, anything targeted, chosen for your child based on what testing actually showed.
I don't order a fixed panel, because there isn't one. There is your child. And when a family's budget means choosing one test over another, I'll tell you honestly which one I'd pick first. Sometimes genomics is not the right next step if the foundations aren't in place yet.
What I won't do
A lot of functional medicine practices get a bad rap because they layer in twenty or thirty supplements at once for a kid. I don't do that, and healthy skepticism is welcome here. Food does the heavy lifting. Anything else is chosen for your child specifically, for as long as they need it and no longer.
I also don't hand out diagnoses or take them away, and I don't do blanket eliminations. There is no one-size-fits-all on cutting dairy or gluten, and I tell families no.
What a first conversation looks like
The first visit is a free Happy Kid consult, and the only question on the table is whether we're a good match for each other. You tell me what's happening. I'll tell you honestly whether I can help, and if I think somebody else is a better fit for your child, I'll say that instead. You can read more about how I work before you decide.
Come with your list. What worries you most, what you've already tried, what you'd want to be different in six months. You are the true expert on your child, and that list is real data.
I'll never accept or tell a parent that this is just how it is. More often than not, that's not true.
