Yes — H. Pylori is a known cause of persistent bad breath (Halitosis) when the problem isn't from teeth or gums.
How It Causes Bad Breath:
- Urea production: The bacterium breaks down urea producing ammonia — which smells foul.
- Hydrogen sulfide production: A gas that smells like rotten eggs.
- Acid reflux: Stomach content reflux causes persistent sour smell.
- Digestive disturbance: Indigestion causes food fermentation and bloating.
How to Know If the Problem Is Gastric:
- Persistent smell despite tooth brushing.
- No dental or gum problems present.
- Accompanied by gastric symptoms (heartburn, bloating, burping).
- Improves after H. Pylori treatment.
Treatment:
Treating the bacteria itself is the solution — mouthwashes and fresheners are only temporary. After eradication, the smell gradually disappears within weeks.
At BEIT TARIQ Center, we test for H. Pylori as part of comprehensive digestive system assessment.
