In this solo episode of The Perfect Stool, host Lindsey Parsons explains post‑infectious irritable bowel syndrome (IBS) – a form of IBS that often follows an acute gut infection such as food poisoning or traveler's diarrhea. She describes how common bacterial culprits (Campylobacter, Salmonella, Shigella, pathogenic E. coli) produce the cytolethal distending toxin B (CDTB), which can trigger molecular mimicry and the production of anti‑vinculin antibodies that damage the gut’s pacemaker cells, leading to impaired motility and small‑intestine bacterial overgrowth (SIBO). Parsons reviews the scientific evidence, especially work by Dr Mark Pimentel, and outlines diagnostic options (IBS‑Smart/Vibrant antibody panels, breath tests including lactulose, glucose, fructose, Triosmart, FoodMarble, and stool testing). She then provides a comprehensive treatment toolbox: prescription antibiotics (rifaximin, bismuth), probiotics (Saccharomyces boulardii, spore‑based blends), serum‑derived bovine immunoglobulin (SBI powder), herbal antimicrobials (pomegranate husk, MSM, allicin), prokinetics (low‑dose erythromycin, tegaserod, prucalopride, low‑dose naltrexone, herbal bitters, ginger‑based formulas, artichoke extracts, 5‑HTP combos), dietary strategies (targeted low‑FODMAP, wheat vs dairy focus, regular beans/lentils, elemental diet, fasting‑mimicking diet), and adjuncts (postbiotic Thanabiotic, fecal transplant). Throughout she interweaves her own decades‑long experience with post‑infectious IBS, shares practical dosing tips, product links, and emphasizes the importance of early identification to prevent systemic inflammation and secondary autoimmune conditions. The episode ends with a call to action for coaching, supplement purchases, and community engagement.
