You’ve had the colonoscopy. You’ve seen the gastroenterologist. You’ve tried the elimination diet, the probiotics, the over-the-counter remedies. And yet here you are — still bloated, still uncomfortable, still without a real answer for what’s happening in your gut.
You’re not failing to find the right solution. The solution isn’t being offered. Across Sugar Land, The Woodlands, Katy, and the Heights, Houston patients come to us carrying years of “normal” results — and a gut that still isn’t right. At Modern Functional Medicine Center, we focus on what conventional gastroenterology often can’t: the functional imbalances driving your symptoms — and what to do about them.
Why Houston Patients Search for Functional Gut Care
Houston is home to the largest medical complex in the world. World-class gastroenterologists. Cutting-edge diagnostic technology. And yet patients across Sugar Land, The Woodlands, Katy, and the Heights keep walking out with the same answer: everything looks normal.
Here’s why. Standard GI evaluations are designed to rule out structural disease — polyps, ulcers, inflammatory bowel disease, cancer. They do that exceptionally well. But the chronic functional symptoms that bring most patients in — bloating, gas, irregular bowel movements, food reactions, low-grade abdominal discomfort — often have causes that scopes and basic stool tests simply aren’t built to find.
When testing comes back “normal,” most patients receive an IBS diagnosis. In conventional practice, that label is often the end of the investigation — not the beginning of one. We treat it as the beginning.
Houston’s climate adds a layer most providers never consider. The city’s high humidity creates conditions favorable for mold growth in homes and workplaces — and mold exposure directly disrupts gut microbial balance. Houston’s food culture is one of the most diverse in the country, which means many patients are quietly reacting to ingredients they can’t easily identify or avoid. These are Houston-specific drivers of gut dysfunction. They require Houston-specific thinking.
What Makes Gut Care “Functional,” “Integrative,” or “Holistic”?
You’ll see these terms used somewhat interchangeably, but they describe related but distinct approaches.
Functional medicine investigates the biological root causes of digestive dysfunction. Rather than naming a syndrome and managing its symptoms, functional medicine asks why the gut is malfunctioning in the first place—and addresses those drivers directly. The Institute for Functional Medicine describes this as a systems-based, root-cause approach.
Integrative medicine combines conventional medical care with evidence-based complementary approaches like nutrition, targeted supplementation, and lifestyle interventions.
Holistic medicine treats the whole person—recognizing that gut health is intimately tied to your stress levels, sleep, immune function, and mental health.
At Modern Functional Medicine Center, our team brings all three together. Dr. Bronwen Martin, DC, IFMCP — one of fewer than 2,000 practitioners worldwide to hold the Institute for Functional Medicine’s highest certification — and Dr. Andy Martin, MD, bring a combination of credentials that is rare in functional GI care. We work alongside your Houston gastroenterologist, not instead of them — addressing the functional drivers that scopes and standard tests simply aren’t designed to find.
Digestive Conditions We Help Houston Patients Address
Through telehealth, we work with patients across the Greater Houston metropolitan area on a wide range of digestive concerns:
SIBO and IMO (Small Intestinal Bacterial Overgrowth and Intestinal Methanogen Overgrowth) cause bloating, gas, food sensitivities, and often alternating constipation and diarrhea. Standard stool tests don’t detect these conditions—specialized breath testing is required.
IBS in all its forms (constipation-predominant, diarrhea-predominant, mixed). Beyond the diagnostic label, we identify the specific drivers in each individual case.
Leaky gut (intestinal permeability) underlies many seemingly unrelated symptoms, from food sensitivities to autoimmune conditions to skin issues.
Chronic bloating and gas that persists despite dietary changes.
Food sensitivities and reactions that seem to multiply over time.
Acid reflux and GERD, including the cases that don’t respond to standard PPI therapy.
Dysbiosis and post-antibiotic gut damage, particularly common after multiple courses of antibiotics or recovery from food poisoning.
How Telehealth Gut Care Works for Houston Patients
Houston is geographically vast — and for patients dealing with chronic gut symptoms, an hour each way on I-10, I-45, or the 610 Loop isn’t just inconvenient. It’s a lot to ask of a body that’s already struggling.
Our telehealth model was built for exactly that reality. You’ll meet with our team through secure, HIPAA-compliant video consultations from your home or office. SIBO breath test kits and comprehensive stool test kits ship directly to your door for at-home collection. Standard lab orders go to Houston-area Quest and LabCorp locations near you. Between visits, you can message our team directly as symptoms come up — no waiting weeks for your next appointment to ask a question.
For gut patients especially, this isn’t just about convenience. Some days you don’t know how you’ll feel until you wake up. Telehealth means your care doesn’t depend on a good day to get to it.

The Specialized Testing We Use
Our diagnostic toolkit goes well beyond standard GI testing. Comprehensive stool analysis (such as the GI-MAP) examines microbiome composition, identifies pathogenic bacteria, parasites, and yeast overgrowth, and measures digestive enzyme function and inflammatory markers. SIBO breath testing uses lactulose-based three-hour tests to measure the hydrogen and methane gases produced by bacterial overgrowth in the small intestine. Food sensitivity panels help identify reactions when clinically indicated. Organic acids testing reveals fungal and bacterial overgrowth markers that other tests miss. Research from the National Institutes of Health confirms that this kind of comprehensive testing identifies functional GI issues that standard panels routinely miss.
This testing depth is what allows us to develop precise, individualized protocols rather than generic gut-health recommendations.
The 4-R Protocol: How We Help Houston Patients Heal
Once we understand what’s driving your specific gut dysfunction, we apply the 4-R Protocol—a systematic framework refined over decades of functional medicine practice.
Remove: We identify and eliminate the factors damaging your gut, whether that’s pathogenic bacteria, fungal overgrowth, parasites, problematic foods, or chronic stress patterns. Replace: We restore the digestive functions you’re missing—stomach acid, digestive enzymes, bile flow—so you can properly break down and absorb nutrients. Reinoculate: We rebuild a healthy, diverse microbiome through targeted probiotic and prebiotic strategies, not generic supplements. Repair: We provide the specific nutrients (L-glutamine, zinc carnosine, omega-3s, others) that your gut lining needs to heal, alongside the lifestyle support that allows healing to happen.
Most Houston patients see meaningful improvement within three to six months. More complex cases—those involving SIBO recurrence, chronic infections, or significant mold exposure—can take longer.
Frequently Asked Questions
Q: Do you replace my Houston gastroenterologist?
A: No. We work alongside specialists. Many patients keep their gastroenterologist for procedures and structural evaluation while working with us for the functional, root-cause work that conventional GI doesn’t address.
Q: I had a colonoscopy and it was “normal.” Why am I still sick?
A: Standard scopes excel at ruling out structural disease, but they can’t detect SIBO, food sensitivities, dysbiosis, leaky gut, or fungal overgrowth. These functional issues require specialized testing—and they cause the majority of chronic digestive symptoms.
Q: Do I have to be in Houston to work with you?
A: No. We provide telehealth care to patients across 32 states. Patients in Sugar Land, The Woodlands, Katy, the Heights, and across Greater Houston benefit from local lab partnerships — but geography has never been a barrier to working with us.
Q: How is this different from a “wellness” or supplement-based gut program?
A: We are licensed clinicians —Dr. Andy Martin, MD and Dr. Bronwen Martin, DC, IFMCP — using advanced diagnostic testing and individualized clinical protocols. Not generic programs, supplement retailers, or wellness coaches. Every recommendation is built on what your labs actually show, not a one-size-fits-all gut protocol.
Q: How long until I notice improvement?
Most Houston patients see meaningful shifts — reduced bloating, more predictable digestion, better energy — within 6 to 8 weeks. More complex cases involving SIBO recurrence, chronic infections, or mold exposure take longer. We track progress throughout so you always know where you stand.
