INTRODUCTIONINTRODUCTION
• Without efficient digestive function, general health cannot prevail
• A “rumble” in the guts produces a “rumble” in the mind and vice versa
• The most common digestive disorders are functional in origin
• Integrative Medicine cannot impact “plumbing problems” in the gut

FUNCTIONAL DIGESTIVE FUNCTIONAL DIGESTIVE DISORDERSDISORDERS
• Commonest cause of digestive upset
• A lack of harmony of digestive function (Claude Bernard)
• Involves the brains of the body and the “brains” of the gut
• The mind-body or body-mind
• Constitutes about 75% of all GI work

RED FLAG SYMPTOMSRED FLAG SYMPTOMS• Difficulty in swallowing
• Common first symptom of cancer of the
esophagus especially in adults.• Persistent, new
abdominal pain • Abdominal pain must be taken
seriously. It may signal serious diseases.
• Family history of bowel cancer, inflammation or polyps
• These diseases run in families.
• Blood in the stool or vomit
• Bleeding common among individuals with cancer or ulcers.
• Change in digestive function in people over the age of 40 years
• Most cancers in the gastrointestinal tract occur with advancing age.
• Systemic symptoms
• Weight loss, fever, joint disease etc.

GERD: ACID REFLUXGERD: ACID REFLUX
• Mismatch between symptoms and severity of esophagitis
• Endoscopy indicated in persistent symptoms or dysphagia
• Oxidative tissue damage contributes to Barrett’s metaplasia (pre-cancer)
• A peptic stricture may hide cancer• Dysphagia over the age of 45 years is
cancer until proven otherwise

GERD: ACID REFLUXGERD: ACID REFLUX• Obtrusive problems with many
unobtrusive issues
• Laryngitis, globus sensation, asthma and COPD
• Coexistence of obesity and Metabolic Syndrome X
• Adverse effects of medication (occult)

HOLISTIC NUTRACEUTICAL HOLISTIC NUTRACEUTICAL APPROACH TO GERDAPPROACH TO GERD
• Neutralize gastric acid: fava bean flour (USP standard), sodium bicarbonate (2% RDI, Na), Ca, Mg
• Natural inhibitors of the proton pump e.g. ellagic acid: c.f. H+/K+ ATP-ase
• Antioxidants: E, C, green tea, turmeric, beta carotene: REDOX balance
• Miscellaneous: mastic gum, lecithin, apple pectin, gastric mucin, Zn

PEPTIC ULCER DISEASE
• Potent antisecretory drugs put surgeons out of work, but their legacy remains with post gastrectomy or post vagotomy complications (DDD)
• Helicobacter pylori is a miscreant
• Mind-body plays a role: Tidy, H, “The Incidence of Peptic Ulcer at St. Thomas’ Hospital” BMJ, 1, 319, 1945
![Page 19: Stephen Holt MD-Natural Ways to Digestive Health](https://reader034.vdocument.in/reader034/viewer/2022051819/5524f267550346d36e8b4607/html5/thumbnails/19.jpg)
PEPTIC ULCERPEPTIC ULCER
Dr. H Tidy stated in 1945, BMJ:
Psychoneurotic stimuli (mind) may pull the trigger (referring to peptic ulcer complications), but some other hand has previously loaded the gun.”

HELICOBACTER PYLORIHELICOBACTER PYLORI
• A bug that lies below the layers of gastric mucus in the antrum
• Switches on acid
• Damages tissue by major generation of free radicals and oxidative stress
• Peptic ulcer disability worse in substance abusers: oxidative stress
![Page 21: Stephen Holt MD-Natural Ways to Digestive Health](https://reader034.vdocument.in/reader034/viewer/2022051819/5524f267550346d36e8b4607/html5/thumbnails/21.jpg)
KEY CONCEPT: THE KEY CONCEPT: THE ANTIOXIDANT APPROACHANTIOXIDANT APPROACH
• The role of oxidative stress in the generation of acid peptic disease has been well defined but ignored as an important focus of therapeutic intervention
• Oxidative stress promotes tissue injury, inflammation, metaplasia and cancer in the upper digestive tract
• All individuals with acid peptic disease should receive REDOX balanced antioxidants

REDUCING THE BURDEN OF REDUCING THE BURDEN OF NSAID DAMAGENSAID DAMAGE
• Reduce NSAID dosage by topical bone and joint rubs with evidence-based dietary supplement strategy
• Synergistic formulation of chondroprotection, herbal Cox-2 inhibition, immune tolerance and specific anti-inflammatory agents
• Therapeutic tips: “delayed onset”
![Page 24: Stephen Holt MD-Natural Ways to Digestive Health](https://reader034.vdocument.in/reader034/viewer/2022051819/5524f267550346d36e8b4607/html5/thumbnails/24.jpg)
IRRITABLE BOWELS OR GUTSIRRITABLE BOWELS OR GUTS
• Visceral learning • About 25M Americans have “The IBS,
a condition that includes the presence of long lasting (>3m) or intermittent abnormalities of bowel habit, with or without lower abdominal pain or discomfort, not explained by causes involving any structural or metabolic changes” c.f. Functional Dyspepsia
![Page 25: Stephen Holt MD-Natural Ways to Digestive Health](https://reader034.vdocument.in/reader034/viewer/2022051819/5524f267550346d36e8b4607/html5/thumbnails/25.jpg)

MANAGEMENT OF IBSMANAGEMENT OF IBS• A perfect target for Integrative
Medicine• Controlled trials reinforce visceral
learning: body-mind approach, relaxation responses, self hypnosis
• A mixed bag of disorders: benefit of smooth muscle relaxation, fish oil, synergistic GI balancing formulae
• Back to Claude Bernard
![Page 27: Stephen Holt MD-Natural Ways to Digestive Health](https://reader034.vdocument.in/reader034/viewer/2022051819/5524f267550346d36e8b4607/html5/thumbnails/27.jpg)
COLON CLEANSINGCOLON CLEANSING
• Synergistic, gentle, herbal, water-retaining supplements which facilitate exodus of stool
• Lifestyle change, fiber etc.
• A role for colon hydrotherapy
• Must consider concepts of CDR
![Page 28: Stephen Holt MD-Natural Ways to Digestive Health](https://reader034.vdocument.in/reader034/viewer/2022051819/5524f267550346d36e8b4607/html5/thumbnails/28.jpg)
FIBER SUPPLEMENTSFIBER SUPPLEMENTS• Soluble and insoluble fibers• Fiber has predictable effects by
consideration of physicochemical properties e.g. bran vs. hydrocolloids
• Soluble fibers have intrinsic metabolic effects
• Fiber must interact with colonic bacteria to exert its many benefits
![Page 29: Stephen Holt MD-Natural Ways to Digestive Health](https://reader034.vdocument.in/reader034/viewer/2022051819/5524f267550346d36e8b4607/html5/thumbnails/29.jpg)
FIBER: THE GLYCEMIC INDEXFIBER: THE GLYCEMIC INDEX
• Calculations of the glycemic index of food are probably a waste of time.
• Understanding factors that control gastric emptying rate can result in inference about the glycemic index.
• Slowing gastric emptying slows glucose absorption – relevance in acute dosing

PROBIOTICS: BENEFITSPROBIOTICS: BENEFITS• Assistance with digestion• Alleviation of digestive disorders, e.g., colitis, IBS, peptic ulcer.• Enhanced mineral absorptions, especially calcium.• Enhancement of the synthesis of several vitamins (especially
B complex).• Protection against pathogenic bacterial infections, e.g., E. coli
infection.• Reduction of symptoms of lactose intolerance; permits limited
reintroduction of dairy products.• Reduction of yeast overgrowth (Candidiasis); notable reduction
in vaginal thrush.• Improvement in immune function; “primes” the gut immune
system.• Anticancer effects, some good evidence.• Prevention of Helicobacter pylori infection and its association
with peptic ulcer, dyspepsia and gastric cancer.• Acne prevention (?)• Cholesterol reduction, modest and unpredictable.

THE CANDIDA CONTROVERSYTHE CANDIDA CONTROVERSY
• Candida albicans: innocuous gut inhabitant or pathogen
• Opportunistic organism with gliotoxin, which depresses immunity
• Combined use of prebiosis, probiosis, enzymes and detox
• Dietary change: sugar elimination

ORGANIC FOODORGANIC FOOD• Favored for enhanced nutrient
density and absence of organochemicals
• Pesticides and fertilizers are growth promoters and may contribute to body toxicity that promotes obesity TOXIC LIPOGENESIS
• Food contamination: strawberries, cherries, apricots, grapes etc.
• Economic disadvantages

PARASITESPARASITES• Clever organisms that are not “fooled
by a dose of salts”
• Effective management involves eradication. Most predictable by the use of drugs, cleansing inadequate?
• Herbal approaches are variable e.g. black walnut, grapefruit seed, wormwood, rosemary, thyme, marshmallow and citrus peel

LEAKY GUTS 1LEAKY GUTS 1• Damage to tight junctions in the
intestinal lining• “Chicken and Egg arguments”• Disease associations: drug usage,
autoimmune disease, gastrointestinal disease, skin disease, AIDS, etc.
• Causes: drugs (NSAID), infections, radiation therapy, trauma, TPN
• Dysbiosis: classic lack of harmony

CONCLUSIONCONCLUSION
• Without digestive health, general health will not prevail
• Practitioners of Integrative Medicine are focused on restoring digestive harmony as a premonitory to the management of all disease
• New advances in nutraceutical technology remain underexplored
• Think digestive health as a baseline
