Duodenal Ulcers

How does BN help with Duodenal Ulcers?
Here is the answer from Dr. Masayuki Sano, MD โ gastroenterologist, oncologist, and surgeon. He is a medical consultant for BN in Japan.
1) Causes of duodenal ulcers
The main causes of duodenal ulcers are:
1.H. pylori infection
2.NSAIDs (non-steroidal anti-inflammatory drugs)
3.Excess stomach acid
4.Reduced mucosal defense
2) Fundamental principle: The main treatment is โPPIโ and โH. pylori eradicationโFor duodenal ulcers, the most important thing is to address the cause and control stomach acid:
Administer PPIs (proton pump inhibitors) to suppress acid secretion
Eradicate H. pylori if present
BN is not a replacement for these treatments. It is a supportive agent that helps create an
environment where the mucosa can recover more easily.
3) How BN supports treatment
โ Antioxidant support (calming the inflammatory environment)
BN suppresses lipid peroxidation
โ Helps to gently regulate the inflammatory environment of the mucosa underlying the ulcer
โ Digestive support (reducing gastrointestinal burden)
BN supports protein digestion
Promotes digestion
โ Reduces post-meal gastrointestinal stress, creating a gentler environment for the mucosa
โ Gut environment support
As a fermented product, BN helps regulate the intestinal microbiome
4) Timing of use (safety-focused)
โ
Recommended timing
โ Recovery phase when symptoms have settled
โ Period of mucosal recovery (when PPIs have stabilized the stomach)
โ Acute phase (when there is pain, nausea, or suspected bleeding)
During the acute phase, priority should be given to:
- Medical intervention (PPIs, etc.)
- Excluding bleeding, perforation, or other complications
Even though BN is a food product, adding anything during the acute phase can sometimes triggerย sensitive reactions.
โ It is safest to start BN after the acute phase has settled.
Ideally, it should be taken consistently for at least three months.
After that, it is recommended to continue with a maintenance dose.
5) ๐ Summary
BN is best used as a supportive measure on top of standard treatment:
- Helps create an environment that does not interfere with mucosal recovery
- Supports a post-meal flow that does not overly burden the gastrointestinal tract
