You Have Tried Everything
Still Struggling Despite Doing All the Right Things
You have cut out gluten, taken probiotics, tried multiple elimination diets, and maybe even had a colonoscopy that came back clear. Yet you are still bloated, still reacting to foods that should be fine, and still exhausted in a way that does not make sense.
The frustrating truth is that standard testing rarely looks at what is actually happening inside your gut environment. The gut microbiome, intestinal permeability, digestive enzyme output, bile acid function, and the gut-brain axis are rarely assessed in a standard clinical workup.
When the ecosystem is dysregulated, symptoms will continue to return regardless of how carefully a person eats — because the structural imbalances driving them have not been addressed. The problem is not the food. It is what is happening to the food.
You have tried everything.
Your gut is still not right.
The Gap in Standard Care
Why Conventional Treatment Has Not Fixed It
Conventional gastroenterology is excellent at ruling out serious structural disease. What it is not designed to do is assess the living ecosystem inside your gut. Conditions like irritable bowel syndrome are largely diagnosed by exclusion, meaning once nothing serious is found, the symptoms are often managed with dietary advice or medication rather than investigated further. The gut microbiome, intestinal permeability, digestive enzyme output, bile acid function, and the gut-brain axis are rarely assessed in a standard clinical workup.
Medications that suppress acid or motility can provide short-term relief but often worsen the underlying environment over time. When the ecosystem is dysregulated, symptoms will continue to return regardless of how carefully a person eats because the structural imbalances driving them have not been addressed.
What We Look For
What Is Actually Driving Your Gut Symptoms
The gut is not simply a tube that food passes through. It houses approximately 70 percent of the immune system, produces neurotransmitters that influence mood and cognition, and communicates directly with the brain via the vagus nerve. When the gut environment is disrupted, the downstream effects extend well beyond digestion. Chronic bloating, fatigue, skin conditions, anxiety, and joint pain can all have gut origins that a standard workup will never connect.
At Wave Functional Health, we look for disruptions in the gut microbiome including overgrowth of opportunistic bacteria, parasites, and fungi. We assess intestinal permeability, often called leaky gut, which allows undigested food particles and bacterial byproducts to enter systemic circulation and drive immune activation. We also look at digestive output, the capacity to actually break down and absorb what you eat, because nutrient deficiency and malabsorption are extremely common in people with chronic gut dysfunction.
Stress physiology, sleep disruption, prior antibiotic use, and early life gut exposures all shape the current state of the microbiome. We treat the gut as a system, not a collection of isolated symptoms, and we look for the pattern that explains the whole picture.
Our Approach
How Wave Functional Health Investigates and Treats Gut Dysfunction
We begin with a comprehensive clinical intake to understand your full history, including medication use, diet, stress load, and prior diagnoses. From there we use advanced functional stool analysis through Nutripath MicrobiomiX metagenomics or GI MAP testing, which maps the bacterial, parasitic, fungal, and viral environment of your gut in far greater detail than a standard culture.
Where indicated we also run organic acid testing, comprehensive blood chemistry through OptimalDX, and assess markers of gut-immune interaction including secretory IgA and zonulin.
Treatment is sequenced to match what your results show. We do not apply a generic gut protocol — the type of dysbiosis, the specific organisms identified, and the broader gut environment all determine what approach will be most effective and in what order.
Comprehensive clinical history
We map your full health timeline including medication use, prior diagnoses, antibiotic history, stress load, and dietary patterns. The history often reveals the root cause before testing begins.
Advanced functional stool analysis
GI MAP or MicrobiomiX metagenomics maps the bacterial, fungal, parasitic, and viral gut environment in far greater detail than a standard culture or colonoscopy.
Address pathogenic overgrowth
Targeted antimicrobial or herbal protocols address the specific organisms identified. This step must come before repair — rebuilding without clearing is one of the most common reasons gut protocols fail.
Repair intestinal lining integrity
Mucosal lining support, immune modulation, and targeted nutrients address intestinal permeability and restore the gut barrier once the primary pathogenic burden has been reduced.
Rebuild a diverse resilient microbiome
Targeted probiotic strains, prebiotic support, and dietary diversity strategies restore microbial balance. Strain selection is based on testing results, not generic supplementation.
Monitor and adjust throughout
Progress is monitored through follow-up testing and clinical reassessment. We adjust the protocol as results evolve rather than applying a fixed timeline.

What We Test and What It Reveals
← Scroll to see full table
| Test | What it reveals |
|---|---|
| Nutripath MicrobiomiX Metagenomics | Full microbial ecosystem mapping including bacteria, fungi, parasites, and viruses. Identifies dysbiosis patterns that conventional culture consistently misses and provides functional pathway analysis of the gut environment. |
| GI MAP (Diagnostic Solutions) | Quantitative PCR stool analysis assessing pathogens, commensal bacteria, digestive markers, and intestinal immune function including secretory IgA, zonulin, and pancreatic elastase. |
| Organic Acids Testing | Metabolic byproducts of gut organisms indicating fungal overgrowth, bacterial fermentation, and mitochondrial function. Reveals what stool testing alone cannot capture about the gut's metabolic environment. |
| OptimalDX Blood Chemistry | Optimal range blood analysis revealing nutrient deficiencies, liver stress, inflammation, and metabolic markers linked to gut dysfunction that standard reference ranges consistently miss. |
| Zonulin and Secretory IgA | Markers of intestinal permeability and mucosal immune defence capacity. Confirms leaky gut where present and guides the repair protocol sequencing and nutrient support strategy. |
| Food Sensitivity Panel | IgG-mediated food reactivity indicating immune activation from dietary triggers, often driven by underlying gut permeability rather than a true intolerance to the food itself. |
| Full Thyroid Panel | Thyroid function directly influences gut motility, microbiome diversity, and digestive enzyme production. Hypothyroidism is a commonly missed contributor to chronic constipation and gut dysfunction. |

Frequently Asked Questions
Questions Patients Ask About Gut Health
A colonoscopy assesses the structural integrity of the large intestine and rules out conditions like polyps, ulcerative colitis, and colorectal cancer. It does not assess the gut microbiome, intestinal permeability, digestive enzyme output, or the functional state of the small intestine.
Many people with significant gut dysfunction receive a normal colonoscopy result because the testing is not designed to find what is actually causing their symptoms. This is one of the most common presentations at Wave.
Yes. The gut and brain are in constant two-way communication via the vagus nerve and through the immune and endocrine systems. The gut produces approximately 90 percent of the body's serotonin. Gut-derived inflammation, bacterial byproducts known as lipopolysaccharides, and disruptions to neurotransmitter production can all significantly affect mood, cognition, and energy levels.
Many patients notice significant improvement in these symptoms once gut dysfunction is properly addressed — when no direct brain or mental health treatment had worked.
Intestinal hyperpermeability is a well-documented physiological state supported by published research. It describes a breakdown in the tight junctions of the intestinal lining that allows larger molecules, including bacterial fragments and partially digested food proteins, to cross into systemic circulation.
This triggers immune activation and low-grade inflammation that can drive a wide range of symptoms throughout the body. It is measurable through functional markers including zonulin and is treatable when properly identified.
Dietary restriction is often a starting point to reduce the burden on a compromised gut, not a permanent solution. As the underlying drivers of dysfunction are addressed through targeted treatment, the gut environment improves and food tolerance typically expands.
The goal at Wave is to restore a functional, resilient gut so that you can eat a broad, varied diet without symptoms — not to keep you restricted indefinitely.
This depends on the severity and duration of dysfunction, the specific organisms or imbalances identified, and individual response to treatment. Many patients notice meaningful improvement in bloating, energy, and bowel regularity within four to eight weeks of beginning a targeted protocol.
Deeper repair of the microbiome and intestinal lining typically takes three to six months. Progress is monitored through follow-up testing and clinical reassessment throughout the programme.
You do not have to keep managing this.
There are answers worth looking for.
If you have spent years being told your gut is fine, or been given dietary advice that provides partial relief at best, you deserve a more thorough investigation. At Wave Functional Health, Dr Matt investigates what standard testing misses and builds a plan that addresses the real drivers.
