When to Test for H. pylori

For functional medicine practitioners, comprehensive stool testing is a cornerstone of root-cause analysis. The GI Effects Comprehensive Stool Profile evaluates digestion, inflammation, microbial balance, and infection in the gut ecosystem. One of the most clinically relevant pathogens that can be added to this profile is Helicobacter pylori, a bacterium with far-reaching implications beyond the stomach.

But when does it make sense to add H. pylori testing and when might it be unnecessary?

Why H. pylori Matters

Although the link between H. pylori and peptic ulcer disease is well known, its clinical relevance extends much further. H. pylori colonization has been associated with:

• Chronic gastritis and gastric cancer risk
• Iron and B12 deficiency (via reduced stomach acid and impaired absorption)
• Food sensitivities due to altered digestion
• Systemic inflammation and autoimmunity (via molecular mimicry)
• Skin conditions (e.g., rosacea, urticaria)
• Dysbiosis and altered gut motility (through its effect on gastric emptying)

Testing for H. pylori becomes particularly important when patients present with upper GI symptoms like bloating, belching, nausea, reflux, or epigastric pain - especially if those symptoms persist despite dietary and lifestyle interventions.

H. pylori testing via stool antigen offers a non-invasive, validated EIA assay that detects active infection, unlike serum antibodies which only indicate past exposure.

When to Add H. pylori to GI Effects

Consider adding H. pylori when your patient presents with...	You might not need it if your patient has...
Unexplained upper GI symptoms (e.g., GERD, ulcers, early satiety) Refractory or recurrent dysbiosis despite therapy Nutrient deficiencies (B12 or iron) with no clear cause Autoimmune conditions, especially thyroid (e.g., Hashimoto's) Chronic skin issues like rosacea or eczema Chronic NSAID or PPIs use	No upper GI symptoms Normal stool inflammatory markers (e.g., calprotectin, EPX, sIgA) No history of ulcers or gastritis Symptoms resolved after prior antimicrobial or microbiome therapy ⚠ Routine H. pylori testing in asymptomatic individuals is not universally recommened, unless there is a compelling family history of gastric cancer or autoimmune disease.

Bottom Line for Providers

Adding H. pylori testing to the GI Effects profile can provide a more complete picture in patients with upper GI symptoms, unexplained nutrient deficiencies, or signs of immune dysregulation. It empowers early, targeted treatment strategies that can prevent more serious complications down the line.

When in doubt, remember that stool antigen testing detects active infection, making it a strategic and practical choice when you're seeking answers in complex GI cases.
