The Short Answer (For Parents Who Are Googling At Night)

Possibly — and no, you’re not imagining things.

At Cedars Functional Medicine LLC, we often meet families who have been dealing with ongoing bloating, gas, abdominal pain, constipation, diarrhea, or IBS-like symptoms for months (or years). Many have already been told, “Everything looks normal.”

When symptoms keep showing up anyway, we start asking a different question: what’s driving the gut to struggle in the first place? That’s where SIBO (small intestinal bacterial overgrowth) and gut dysbiosis sometimes enter the conversation.

First, Let’s Normalize This

If your child:

• Bloats after most meals
• Has gas that seems wildly out of proportion to what they ate
• Alternates between constipation and diarrhea
• Complains of frequent stomach pain with no clear trigger
• Eats normally but feels miserable afterward

You are not alone — and this is not just “a sensitive stomach.”

Chronic gut symptoms are one of the most common reasons families seek integrative pediatric care, especially when standard testing hasn’t provided answers.

What Are SIBO And Dysbiosis (In Plain English)?

SIBO: Right Bacteria, Wrong Place

SIBO occurs when bacteria that normally belong in the large intestine migrate into the small intestine, where they are not meant to live in large numbers.

When food reaches those bacteria too early, fermentation occurs — leading to:

• Bloating
• Gas
• Abdominal pain
• Diarrhea, constipation, or both
• Nausea
• Feeling full very quickly

Research led by Dr. Mark Pimentel, MD, a gastroenterologist at Cedars-Sinai, has shown that impaired small-intestinal motility is a major driver of SIBO. When the gut’s natural “clean-up wave” (the migrating motor complex) isn’t working well, bacteria are more likely to accumulate where they shouldn’t.

Dysbiosis: When The Gut Ecosystem Is Out Of Balance

Dysbiosis refers to an imbalance in the gut microbiome — too many unhelpful microbes, not enough beneficial ones, or the wrong mix overall.

Studies in both children and adults associate dysbiosis with:

• Functional abdominal pain
• IBS
• Constipation and diarrhea
• Increased gut sensitivity
• Low-grade inflammation

In short: the gut ecosystem matters.

Why Do These Issues Show Up In Kids And Teens?

SIBO and dysbiosis rarely have a single cause. They usually develop from a combination of factors, including:

• Repeated antibiotic exposure
• Chronic constipation or slow gut motility
• Reflux treated with long-term acid suppression
• Prior gastrointestinal infections
• Stress and anxiety
• Poor sleep
• Inadequate fiber type (not just amount)
• Constant grazing instead of structured meals

Dr. Pimentel’s research helps explain why many children with IBS-type symptoms also struggle with bacterial overgrowth — motility and nervous-system regulation play a central role.

The Gut–Brain Connection (Science, Not “It’s All In Their Head”)

The small intestine is tightly regulated by the nervous system.

Peer-reviewed research shows that stress and nervous-system dysregulation can:

• Slow gut motility
• Increase the risk of bacterial overgrowth
• Heighten pain perception
• Worsen bloating and discomfort

This does not mean symptoms are psychological. It means the gut and brain are in constant communication — and sometimes that communication gets a little too intense.

(If you’ve ever had a nervous stomach before a big event, you’ve experienced this firsthand.)

Why “Just Take A Probiotic” Often Doesn’t Help — And Sometimes Makes Things Worse

Probiotics can be helpful at the right time.

But when bacteria are already overgrowing in the wrong place, adding more bacteria can sometimes increase bloating and gas, not improve it.

As Dr. Allison Siebecker, ND, MS, LAc — a leading SIBO clinician and educator — explains, effective SIBO care requires:

• Addressing gut motility
• Identifying underlying triggers
• Proper sequencing of diet, antimicrobials, and probiotics

In other words: timing matters.

Our Integrative Evaluation: Thoughtful, Not Excessive

Depending on your child’s symptoms, we may evaluate:

• Symptom patterns and timing
• Growth and weight trends
• Diet quality and structure
• Stool habits and motility clues
• Medication and antibiotic history
• Stress load and sleep quality

In select cases, targeted testing may help guide care instead of relying on trial and error. This approach aligns with American Academy of Pediatrics guidance when GI symptoms are persistent or affecting quality of life.

Diet Changes: Strategic, Temporary, And Explained

When dietary changes are recommended, they are:

• Specific
• Time-limited
• Closely monitored
• Designed to support healing — not restriction

This may include:

• Temporarily adjusting fermentable carbohydrates
• Supporting proper meal spacing
• Improving protein and fiber quality
• Reducing constant snacking (often a big one)

These strategies are consistent with clinical frameworks taught by the Institute for Functional Medicine (IFM) and with Dr. Siebecker’s emphasis on addressing root causes before liberalizing diet.

Supplements: Tools With A Job To Do

In integrative care, supplements are used with intention, not enthusiasm alone.

Depending on the child, this may include:

• Motility support
• Targeted antimicrobials (when appropriate)
• Digestive supports
• Carefully selected probiotics at the right stage
• Micronutrients that support gut and nervous-system health

The goal is not long-term dependence — it’s restoring balance.

Lifestyle And Mindset (Still Important)

We also address:

• Sleep quality
• Stress and pressure
• School and social demands
• Bathroom routines
• Movement

Gut symptoms often improve when the nervous system feels safer and more regulated — a theme that runs through both motility research and clinical SIBO experience.

How This Differs From A Conventional-Only Approach

Conventional care often asks: “Is this something we need to worry about medically?”

Integrative care also asks: “What’s driving these symptoms, and how do we support healing?”

We absolutely use conventional treatments when indicated. We simply don’t stop at symptom suppression.

Our Bottom Line

Ongoing bloating, gas, and gut discomfort are not random — and they’re not “just how your child is.”

SIBO or dysbiosis may be part of the picture, but more importantly, there is usually a path forward.

Our goal is to:

• Identify root contributors
• Reduce symptoms
• Restore gut balance
• Help kids feel comfortable eating, learning, and being kids again
