What Is IBS & Gut Issues?

The most frustrating thing about an IBS diagnosis isn't the symptoms — it's the explanation that comes with it. 'Your colonoscopy was normal, so it's IBS.' As if not finding structural damage on a scope means there's nothing wrong. As if the bloating, the unpredictable urgency, the post-meal cramping, the days where leaving the house feels impossible — all of that is just functional. IBS is functional in the sense that it involves functional gut dysfunction, not structural damage. That distinction matters because functional dysfunction has specific, identifiable, and treatable causes. SIBO — small intestinal bacterial overgrowth — is found in up to 78% of IBS patients in research studies, and is directly responsible for the gas, bloating, and altered motility most patients describe. Food sensitivities drive the majority of the rest. Gut motility dysregulation, post-infectious microbiome changes, and the gut-brain axis disruption that follows chronic stress round out the picture. None of these show up on a colonoscopy. All of them show up on functional testing.

Common Symptoms

Recurring abdominal pain or cramping, often relieved by bowel movements
Bloating and visible abdominal distension
Diarrhea, constipation, or alternating patterns of both
Urgency — needing to rush to the bathroom
Mucus in the stool
Incomplete evacuation — feeling like the bowel hasn't fully emptied
Symptoms that worsen with stress, certain foods, or hormonal changes
Associated fatigue, brain fog, and mood symptoms — the gut-brain connection

Root Causes: A Functional Medicine Perspective

IBS is now understood as a gut-brain axis disorder with multiple overlapping root causes. Small intestinal bacterial overgrowth (SIBO) — where bacteria from the colon migrate into the small intestine — is found in up to 78% of IBS patients and drives the bloating, pain, and altered motility characteristic of IBS. Intestinal permeability (leaky gut) allows bacterial endotoxins to enter the bloodstream, triggering systemic and gut-localized inflammation.

Food sensitivities — particularly to fermentable carbohydrates (FODMAPs), gluten, and dairy — trigger IBS symptoms without causing the measurable damage seen in celiac disease. Enteric nervous system dysfunction — where the nerve network governing the gut is dysregulated — alters gut motility and pain sensitivity. Prior GI infections (post-infectious IBS), antibiotic use, and chronic stress all disrupt the gut microbiome in ways that perpetuate IBS.

Dr. Hendry's functional medicine approach tests for SIBO, intestinal permeability, food sensitivities, microbiome dysbiosis, and inflammatory markers to build a complete picture of each patient's gut dysfunction — rather than treating IBS as a single entity requiring a single solution.

How We Treat IBS & Gut Issues at IHP

Acupuncture for IBS is supported by multiple systematic reviews showing significant improvement in abdominal pain, bowel habits, and quality of life compared to sham acupuncture and standard care. Acupuncture regulates the enteric nervous system, reduces gut hypersensitivity, modulates the gut-brain axis, and reduces the stress-response amplification that worsens IBS.

Dr. Hendry's functional medicine protocol for IBS is individualized based on testing results: SIBO treatment (herbal antimicrobials or prescription antibiotics followed by microbiome restoration), low-FODMAP or specific elimination diet guidance, intestinal permeability healing (glutamine, zinc carnosine, collagen, and probiotics), and targeted supplementation for motility support. Chinese herbal medicine formulas — traditionally used for digestive conditions for thousands of years — address specific TCM patterns (Liver-Spleen disharmony, Damp-Heat, etc.) that correspond to distinct IBS presentations.

Dr. Hendry's Approach

I run a SIBO breath test on essentially every IBS patient who comes in. The literature puts SIBO prevalence at up to 78% in IBS — that's too high to skip the test and go straight to a generic fiber and stress management recommendation. What I find shapes the protocol: methane-dominant SIBO (typically constipation-predominant IBS) is treated differently than hydrogen-dominant SIBO (typically diarrhea-predominant), and both require gut restoration work after the bacterial overgrowth is cleared. I also test food sensitivities and, where clinical suspicion is high, intestinal permeability markers. The protocol that comes from actual data produces much better outcomes than the standard IBS advice most patients have already tried and abandoned.

Frequently Asked Questions About IBS & Gut Issues

Small intestinal bacterial overgrowth (SIBO) occurs when colonic bacteria colonize the small intestine, where they ferment food and produce hydrogen and methane gas — causing bloating, pain, and altered bowel habits. It's diagnosed with a hydrogen/methane breath test and is highly treatable.
Stress doesn't cause IBS structurally, but the gut-brain axis means psychological stress directly affects gut motility, permeability, and pain sensitivity. Addressing both the gut biology and the stress-response regulation is essential for lasting IBS improvement.
The low-FODMAP diet is a short-term diagnostic and symptomatic tool, not a permanent diet. When used as an elimination protocol to identify specific triggers, followed by systematic reintroduction, it provides valuable information. Long-term FODMAP restriction is not recommended as it impoverishes the gut microbiome.
Many patients notice improvement in pain and bloating from their first few acupuncture sessions. Sustained improvement in bowel habit regularity typically requires the full gut restoration protocol — usually 8–12 weeks of consistent treatment.
IBD (inflammatory bowel disease — Crohn's disease and ulcerative colitis) involves measurable structural inflammation and damage in the gastrointestinal tract, visible on colonoscopy and detected in blood markers. IBS does not involve visible structural damage but represents functional and neurological gut dysfunction. Both respond to integrative treatment.
