If your patient took an antibiotic, give them a probiotic.
Because it’s good.
The end.

When you tell your patients about good bacteria
they only half hear you.

How I think about treatment
1. Diet – not always curative but always important to health
2. Microbiota – almost always contributes to the problem
(probiotics, prebiotics, occasionally killing)
3. Nutrient deficiencies – will make healing and repair, as
well as feeling good impossible if there are major
deficiencies
4. Healing and repair
5. Help – enzymes, HCl stimulators, HCl, prokinetics

…And Sleep Matters Too
“In fact, if you start asking the IBD patients in your
practice about sleep fragmentation, it may be a
predictor for who in remission is going to go to a
flare in the next 6 months, with odds ratios increasing anywhere from two to three times.”

IBS - Diet
Most recently, and belatedly, the important role of the
ubiquitous interloper into the gastrointestinal environment,
food, has begun to be recognized and serious research
efforts devoted to understanding its role in IBS and to the
development of dietary approaches to the management of
IBS.

IBS – Low-FODMAP Diet
IBS symptoms are linked to FODMAP content and
associated with alterations in the metabolome. In subsets
of patients, FODMAPs modulate histamine levels and the microbiota, both of which could alter symptoms.
Histamine was reduced eightfold

IBS – Spelt Sourdough
In conclusion, breads fermented by the traditional long
fermentation and sourdough are less likely to lead to IBS
symptoms compared to bread made using the Chorleywood Breadmaking Process. [short processing time, lower quality wheat]

Digestive enzymes are classified based on their target
substrates:
o Proteases and peptidases split proteins into small
peptides and amino acids.
o Lipases split fat into three fatty acids and a glycerol
molecule
o Amylases split CHO such as starch and sugars into
simple sugars such as glucose

IBS – Gut/Brain Connection
GABA selectively increases the expression of MUC1, a cell
surface mucin that prevents the adhesion of microorganisms,
because of its size and negative charge, and therefore propose
that the well-described positive effects of glutamine on
enterocytes and intestinal integrity are partly attributable to effects of its metabolite GABA.

GERD – Food Allergies
Treatment with GAS medications is associated with the
occurrence of food allergy, an effect not apparently related to a diagnosis of GERD alone.

H. Pylori
We conclude that H. pylori presence and CD are inversely
associated, a relationship that persists after adjustment for
socioeconomic factors. Future studies should address whether H. pylori modulates immune responses to ingested gluten.

H. Pylori
Helicobacter pylori is a late-in-life human pathogen with potential early-

microbiota and host immune responses not only locally in the stomach, but distantly as well, affecting important target organs

GERD - Probiotics
In infants with functional GER, L. reuteri DSM 17938 reduce
gastric distension and accelerate gastric emptying. In addition,
this probiotic strain seems to diminish the frequency of regurgitation.

GERD - Probiotics
The sequential treatment regimen achieved a significantly higher
eradication rate of H. pylori compared with standard 7-d
regimen. L. reuteri supplementation could reduce the frequency and the intensity of antibiotic-associated side-effects.

L. reuteri combination alone is able to exert an inhibitory effect
on H. pylori growth, and when administered with eradication
therapy, it determines a significant reduction in antibiotic-associated side effects.

discontinue at least one of their prior IBD medications, and all
patients had symptom reduction including bowel frequency.

IBD-AID Nutritional RegimeThere are 4 basic parts to the diet that need to be included
on a daily basis + texture changes to food:
1. Prebiotic food
2. Probiotic food
3. Good balanced diet
4. Avoidance of certain foods (modified specific CHO diet)
- No processed foods, trans, refined sugar, grains (except
oats), lactose

PHGG promotes colonic epithelial cell wound. These
findings indicate that PHGG could be utilized as a
therapeutic agent for patients with intestinal mucosal damage such as those with IBD.

The majority of these studies indicate that melatonin has a
positive impact on IBD with no or negligible side effects. Such
results have been mostly explained through free radical scavenging and diminishing inflammation.
