In integrative medicine there are the 4 R's (there's actually 7 now! but let's stick to old time basics):
Treating the overall gut, with
exclusion or rotation diets,
glutamine, fish oils for inflammation,
and the entire 4-R program includes:
Treatment Using Four “R” Program for
Intestinal Health:
• Remove offending foods, medications,
gluten (if sensitive) and reduce high
fat foods, refined carbohydrates,
sugars, and fermented foods (if yeast
is present). Consider antimicrobial,
antifungal, and/ or antiparasitic
therapies in the case of
opportunistic/ pathogenic bacterial,
yeast, and/or parasite overgrowth (see
otherrecommendations below).
• Replace what is needed for normal
digestion and absorption such as
betaine HCl, pancreatic enzymes, herbs
that aid in digestion such as
deglycyrrhizinated licorice and
marshmallow root, dietary fiber, and
water.
• Reinoculate with favorable microbes
(probiotics such as Lactobacillus sp.,
Bifidobacter sp., and Saccharomyces
boulardii). To enhance the growth of
the favorable bacteria, supplement
with prebiotics such as insulin,
xylooligosaccharides, and fiber.
• Repair mucosal lining by giving
support to healthy intestinal mucosal
cells, goblet cells, and to the immune
system. Consider L-glutamine,
essential fatty acids, zinc,
pantothenic acid and vitamin C.
Other Recommendations for Increasing
sIgA
• Exercise and relaxation techniques
(such as footbaths, aromatherapy and
massage) have been shown to increase
sIgA levels.
• Decrease cortisol levels. Cortisol
can direct the production of immune
cells immuncytes, which produce
sIgA.Probiotics (bifidobacter and
Lactobacillus bacteria) have been
shown to increase sIgA (as well as
beneficial short chain fatty acids).
They may also activate macrophages.
• Saccharomyces boulardii is used for
the prevention and treatment of
diarrhea of different etiologies and
has been shown to enhance IgA immune
response
