IBS & Gut Barrier Dysfunction
Symptoms are mapped across diet, motility, visceral sensitivity, microbial ecology, immune activation and exposures, while red flags are routed to conventional evaluation first.
Key points
- Core Fifth Estate case: a stool organism report is classified as active infection, colonization, dysbiosis hypothesis, past exposure or incidental detection before any antimicrobial is discussed.
- Test to discuss: Red-flag screen (bleeding, weight loss, anemia, onset over 50)
- Test to discuss: Celiac serology and calprotectin
- Test to discuss: Targeted stool studies only when justified
- Test to discuss: Symptom and food diary
- Regular meal timing and fiber titration
- Stress and sleep management
- Avoid unnecessary antibiotics
Root-cause chain
I · Observational association · Post-infectious IBS cohorts show persistent mucosal immune changes and altered sensation.
N · Randomized evidence · Low-FODMAP trials demonstrate symptom reduction in a substantial subgroup.
I · Mechanistic plausibility · Bile-acid malabsorption and microbial shifts plausibly affect transit; testing is often inconclusive.
B · Randomized evidence · Gut-directed hypnotherapy and CBT reduce symptom severity in trials.
Protocols by lane
Evidence grade + regulatory statusGuideline-based agents for IBS-C, IBS-D and pain-predominant subtypes.
Status: FDA-approved · Cautions: Subtype-specific contraindications; review before each change.
Effective in a defined subgroup when supervised.
Status: Lifestyle · Cautions: Avoid long-term restriction; nutrient adequacy and eating-disorder risk must be monitored.
Reduces symptom severity with durable effects.
Status: Lifestyle · Cautions: Requires trained practitioner.
Improves global symptoms, particularly in IBS-C.
Status: Supplement · Cautions: Start low; worsens bloating if escalated quickly.
Antispasmodic benefit in several trials.
Status: Supplement · Cautions: Reflux aggravation; avoid in significant GERD.
Minimal controlled evidence.
Status: Investigational · Cautions: Never a substitute for red-flag evaluation.
Monitoring
- Symptom severity score monthly
- Dietary adequacy review during restriction
- Reintroduction schedule after low-FODMAP phase
