Dr. Zhang Liwen
Oral malodor can be caused by *Helicobacter pylori*. This bacterium is commonly associated with conditions such as gastritis, gastric pain, excessive gastric acid secretion, and dyspepsia. Excess gastric acid can lead to dyspepsia, which in turn may exacerbate digestive symptoms. When halitosis is caused by *H. pylori*, the odor often originates from the esophagus. To completely eliminate this type of oral malodor, targeted eradication therapy against *H. pylori* is required.
