IBS

Gradual Fiber for IBS & Gut Tolerance

1Get IBS diagnosed by a clinician (Rule out red-flag symptoms (unexplained weight loss, rectal bleeding, anemia, family history of GI cancer or IBD) with a physician before starting an elimination diet)
2Monash low-FODMAP elimination, then structured reintroduction (Eliminate high-FODMAP foods for a short defined period, then reintroduce them one FODMAP group at a time to identify personal triggers, ideally with a dietitian)
3Gradual fiber and FODMAP reintroduction to build tolerance (Instead of staying strictly low-FODMAP long-term, slowly and incrementally increase fiber and reintroduce FODMAP foods over weeks, watching symptom response as you go)

IBS

SIBO: The Low-Fermentation Diet (What To Eat During and After Treatment)

1The primary SIBO treatment is a physician-prescribed antibiotic course (commonly rifaximin, sometimes with neomycin or metronidazole for methane-predominant SIBO) (n/a, physician-prescribed and monitored)
2Eat normally, without cutting carbohydrates, for the duration of your antibiotic course (n/a)
3Once antibiotic treatment ends, shift to a low-fermentation diet: more liberal than low-FODMAP, limiting the most fermentable foods without eliminating broad food categories (Ongoing, individualized with a dietitian if possible)

What to buy

Ginger root extract capsules ~$15
