Digestive Health & Gut Nutrition

IBS is a description rather than an explanation. This library studies the physiology behind digestive complaints for educational purposes (microbial balance, motility, food reactions and gut–brain relationships) and where each requires medical assessment.

Digestive Health & Gut Nutrition

Possible contributing factors.

01

SIBO / SIFO: bacterial & fungal overgrowth

02

Dysbiosis & low microbial diversity

03

Food intolerances & histamine load

04

Post-infectious gut damage

05

Gut–brain axis dysfunction & visceral hypersensitivity

06

Low stomach acid & enzyme insufficiency

Five educational case studies.

Fictional, simulated or appropriately de-identified, presented exactly as they are discussed in class. Tap a case to open the educational walkthrough.

Overlooked detailsStarted after a bout of food poisoning in college: post-infectious IBS, never linked.
Possible contributing factors discussedMethane-positive SIBO, slowed motility, fear-driven food restriction down to 8 'safe' foods.
Educational framework exploredSIBO framework, prokinetic support, structured food re-expansion.
Educational takeawayLearning point: how a post-infection timeline is considered when studying digestive complaints.
Overlooked detailsHeartburn since his 20s treated with acid suppression, while his actual acid was low.
Possible contributing factors discussedHypochlorhydria from long-term PPIs, downstream dysbiosis, B12 and iron depletion.
Educational framework exploredPhysician-coordinated PPI taper, digestive support, mineral repletion, fermented-food ladder.
Educational takeawayLearning point: the educational discussion around long-term acid-suppression and digestion; changes to medication are for the physician.
Overlooked detailsSymptoms track stress with total precision; the gut–brain axis was the primary lesion.
Possible contributing factors discussedVisceral hypersensitivity, cortisol spikes, caffeine on an empty stomach, no safety signals to the gut.
Educational framework exploredNervous-system regulation first (breath work, meal rituals), then gentle microbiome rebuilding.
Educational takeawayLearning point: the gut–brain relationship as a possible contributing factor alongside diet.
Overlooked detailsSymptoms worsened steadily after gallbladder removal 4 years ago; fat digestion was never supported.
Possible contributing factors discussedBile insufficiency, pancreatic enzyme insufficiency, fat-soluble vitamin depletion.
Educational framework exploredBile & enzyme support, smaller fat loads more often, A/D/E/K repletion.
Educational takeawayLearning point: fat digestion after gallbladder removal as a topic for educational discussion and referral.
Overlooked detailsThe rash-plus-gut pattern pointed at histamine, confirmed by a low-histamine trial.
Possible contributing factors discussedHistamine intolerance on top of dysbiosis; DAO insufficiency; daily kombucha making it worse.
Educational framework exploredShort low-histamine phase, DAO cofactors, targeted probiotic strains, then reintroduction.
Educational takeawayLearning point: how structured food trials are framed educationally, and when allergy or dermatology referral is needed.
