Comprehensive Stool Analysis & Gut Microbiome Testing

A comprehensive stool analysis measures the gut microbiome and digestive function — bacterial overgrowth, H. pylori, parasites, digestive enzymes like elastase, and inflammation markers — to show what is driving your heartburn. In our Wilmington practice, we use it to connect reflux symptoms to specific gut imbalances, so your plan targets the actual problem instead of another guess.

What This Test Actually Measures

Stool testing today is nothing like the simple "culture and see" test of decades past. The panels we use read your gut ecosystem in detail. Here is what comes back:

• Communal gut microbiome analysis — which bacterial families are dominant, which are depleted, and whether the balance favors fermentation and gas production after meals.
• Bacterial overgrowth markers — evidence of SIBO-type patterns and dysbiosis that create pressure pushing stomach contents upward.
• H. pylori detection — stool antigen testing for the stomach organism linked to disrupted acid regulation. What we see clinically is that when biofilm is present, conventional breath tests can miss strains — so we look carefully here.
• Parasitology — screening for intestinal parasites that inflame the gut lining and impair digestion.
• Digestive markers — pancreatic elastase (a read on your enzyme output), fat and fiber digestion, and short-chain fatty acid patterns.
• Inflammation markers — calprotectin and similar markers that tell us whether the gut lining is actively irritated.
• Immune markers — secretory IgA, which reflects the state of your gut immune defenses.

How Digestion and Reflux Are Connected

Most people think of heartburn as too much acid. In a lot of the cases we see, the trouble is weak digestion. When stomach acid or enzymes are low, food sits and ferments. Fermentation creates gas. Gas creates pressure. Pressure pushes contents back up through the lower esophageal sphincter — and you feel heartburn.

The same chain runs through bacterial overgrowth: microbes fermenting your meals in the wrong place create the same upward pressure. Stool testing is how we find these patterns instead of assuming them.

Who Should Consider Stool Testing

• Heartburn that flares after meals, especially carbohydrate-heavy ones
• Bloating, gas, or a "food baby" sensation alongside reflux
• Unexplained bowel changes — constipation, diarrhea, or both
• A suspected or treated H. pylori infection that keeps coming back
• GERD symptoms that persist despite normal endoscopy results
• Long-term antacid or PPI use with unresolved symptoms

Conventional Stool Testing vs. Our Functional Panels

Topic	Conventional stool testing	Our comprehensive stool analysis
What it screens	Pathogens (infection)	Pathogens plus microbiome balance and digestion
H. pylori	Breath test or basic stool test	Stool antigen and functional panels, looked at closely
Digestion markers	Rarely included	Elastase, fat and fiber digestion, SCFA patterns
Inflammation	Only when disease is suspected	Calprotectin and immune markers on every panel
Use for reflux	Not designed for it	Built to explain functional reflux drivers

How Collection Works

1. We mail you an at-home collection kit with clear instructions.
2. You collect the sample at home — no clinic visit required — and mail it to the lab in the prepaid packaging.
3. Results are typically back within 7 business days.
4. We schedule a dedicated results review where we go through every marker with you, page by page.

No colonoscopy prep, no sedation, no waiting room. Most patients tell us the hardest part was remembering to mail the kit.

What Happens After Your Results

Results without a plan are just paperwork. At your review appointment, we translate the markers into plain language: what is overgrown, what is missing, what is inflamed, and what that means for your reflux. Then we build your care plan around the findings. That may mean targeted changes to what you eat, support for the digestive function your markers show is low, and a stepwise approach to calming the inflammation we found. Where medication is involved, we build any step-down with your prescribing doctor — see PPI cessation support.

Stool testing is often paired with the 184 food sensitivity panel or adrenal stress testing, since gut trouble rarely travels alone. It is one core piece of our 3-Step Root Cause Heartburn Protocol, and it is available by mail anywhere in North Carolina through Wilmington Functional Medicine.
