Helicobacter pylori (H pylori) infection is strongly linked to halitosis. Eradicating H pylori significantly reduces bad breath, suggesting it plays a role in the condition.
Area of Science:
- Gastroenterology
- Oral Medicine
Background:
- Halitosis, or bad breath, is a common condition with various potential causes.
- Helicobacter pylori (H pylori) infection has been investigated as a potential contributor to halitosis.
Purpose of the Study:
- To determine the correlation between H pylori infection and halitosis.
- To assess the effectiveness of H pylori eradication therapy in improving halitosis.
Main Methods:
- A comprehensive meta-analysis was conducted, searching multiple electronic databases up to December 2015.
- Included studies were published in English and Chinese, with data extraction and quality assessment performed independently and in duplicate.
Main Results:
- The analysis of 21 studies revealed a significant association between H pylori infection and halitosis (OR=2.85, P=0.004).
- Successful H pylori eradication therapy led to a substantial reduction in halitosis (RR=0.17, P<0.0001).
Conclusions:
- There is clear evidence linking H pylori infection to halitosis.
- H pylori may be a significant factor in the pathophysiology of halitosis, and eradication therapy could be a viable treatment for persistent cases.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
